Overview: from January to may, the crude steel output of steel increased in China by 27.81% year on year, and the output of bearing steel increased by 22.08% year on year. Looking back on the bearing steel market in June, affected by the off-season demand, the market demand of related varieties of premium special steel has obviously weakened, and China’s bearing steel market price is also weak. So far, the average price of bearing round steel 50 mm (continuous casting) is 6470 yuan / ton, 320 yuan / ton lower than that at the end of May, with a month on month decrease of 4.71%. Recently, the steel pipe plants and forging plants are weak in orders, while the bearing steel enterprises are insufficient in actively reducing production, which reflected the increase of social warehouse and factory warehouse. At present, the demand is still affected by the off-season, and it is difficult to release it by a large degree. It is expected that the market price of bearing steel may show a trend of volatility and weakening in July.

I. Output of bearing steel in China

Output of bearing steel from January to may 2021: both crude steel and steel increased year on year.

According to the data of the Special Steel Enterprises Association of China, the output of cruel bearing steel was 1.9756 million tons in China's main excellent special steel enterprises from January to may 2021 , an increase of 32.03% compared with the same period last year. From January to may 2021, the output of bearing steel of China's main excellent special steel enterprises is 1.6929 million tons, an increase of 26.12% compared with the same period last year.

II. Market performance of bearing steel in China

In June, the prices of bearing steel in China showed a downward trend, and the overall market performance was not good. Due to the particularity of the season, the whole country is hot and rainy, and the overall inventory is large in June. The orders of some high-end bearing manufacturers are great. In addition, the current market is falling again, which alleviates the risk of high price in the early stage and digests part of resources, which plays a certain role in supporting the price. The space for price decline in the later stage is limited. However, the feedback from the current situation shows that the demand of automobile, engineering, wind power and other downstream industries is not optimistic, and the demand for bearing steel may remain low. In view of the limited supporting effect of demand on the price, coupled with the continuous release of steel production capacity, it is expected that the market price of bearing steel in July will show a weakening trend.

III. Relevant market information

(1) Price of raw materials

The market performance of common carbon scrap is relatively strong, with the average price at the end of the month at 3215 yuan / ton. At the beginning of this month, the arrival of steel scrap continued to decline, and scrap prices continued to rise. Later, as the price of thread steel continued to decline, the profits of steel mills were greatly compressed, the price of scrap was depressed one after another. However, due to the tight supply of scrap, the decline of scrap price was not large.

(2) Downstream industry

According to the statistics of China Automobile Industry Association, in May 2021, the production and sales of automobiles were 2.04 million and 2.218 million, with a month on month decrease of 8.7% and 5.5%, and a year-on-year decrease of 6.8% and 3.1%. From January to May this year, automobile consumption remained stable on the whole. Judging from the market, the production and sales of automobiles in this month decreased year on year. Looking forward to the future, China's economic operation is stable and strengthening, which plays a good supporting role in the stability of automobile consumption. However, the global epidemic is still spreading, the global economic recovery is uneven, and China’s economic recovery foundation is not solid, which also brings difficulties for automobile industry.

IV. Conclusion

In June, the market price of bearing steel is still weak, the demand is obviously affected by the off-season, and the inventory accumulation speed is accelerated. At present, the price gap between GCr15 and 45# carbon structural steel has expanded, and the price gap of some steel plants has reached 600-800 yuan / ton. Recently, the demand of bearing steel pipe plants and forging plants has declined obviously, the end users are more cautious in purchasing, and downstream industries still worried. The output of bearing steel production enterprises is high. Under the high inventory pressure, capital flow and risk control are particularly important.

From the perspective of demand, the southern region entered a continuous high temperature after ending of plum rain season in July, so it is difficult to recover demand. In addition, the release of steel production capacity is not reduced, it is expected that the bearing steel market may show a trend of weakening in July.

Elementor是一个免费的WordPress页面构建器插件，拥有超过500万个活动安装。此外，该插件还具有高级版本和数百个附加组件，可在您的网站中添加精美的元素。与任何其他页面构建器插件一样，Elementor添加了自定义样式和脚本，为页面的前端外观添加了令人惊叹的因素。但是，它会在前端和后端影响您网站的页面加载速度的高成本。那么Elementor加载缓慢如何解决?

1、 仅对页面启用Elementor

默认的WordPress设置允许您创建两种文章类型——文章和页面。此外，像WooCommerce这样的插件将创建产品，您还可以根据需要创建自定义文章类型。我们强烈建议只为页面启用Elementor，而不是为文章和其他自定义文章类型启用。这有助于在前端和后端禁用除页面之外的Elementor资源的加载。当您激活Elementor插件时，它将默认为文章和页面启用。您可以转到“Elementor > Settings”菜单并在“General”选项卡下禁用文章插件。

2、 使用Elementor Experiments

该插件在“Experiments”选项卡下提供了许多实验性功能。在这里，您可以看到正在进行的实验以及已完成并被接受为稳定功能的实验。为了提高加载速度，您可以在稳定和持续部分下启用所有与速度相关的项目。

3、优化字体使用

使用Google字体和其他自定义字体会在Google PageSpeed Insights中产生很多问题。例如，当您使用带有Elementor插件的Google Fonts时，您会看到在加载Web字体和预加载字体时使文本可见的警告。幸运的是，Elementor具有内置的字体优化选项，您可以使用它们来提高页面加载速度。

4、使用外部CSS文件

正如您在上面的屏幕截图中看到的那样，Elementor允许两个“CSS Print Method”选项。一种是使用“External File”，另一种是使用“Internal Embedding”。选择“External File”选项，以便将所有CSS样式作为外部文件加载。之后转到“Elementor > Tools > General”部分，然后单击“Regenerate Files & Data”。这将重新生成数据并作为外部CSS文件加载。它将有助于正确缓存页面并提高速度，而不是动态注入无法缓存的CSS。

5、尝试安全模式

如果您在创建或编辑页面时遇到加载缓慢的Elementor编辑器，则可以使用“Elements > Tools > General”部分下的安全模式。安全模式会在加载缓慢时在编辑器中显示建议。

6、 减少附加组件的数量

有数百个第三方插件可用作Elementor页面构建器插件的附加组件。这些插件将为基础插件添加额外的元素以创建漂亮的布局。但是，这些插件可能无法很好地与父Elementor插件一起使用，尤其是当父插件更新到较新版本时。此外，附加组件将添加额外的CSS/JS并增加HTTP请求。如果您喜欢 Elementor，请转到提供足够元素和模板库的 Pro 版本。避免使用第三方插件来添加一些可能会降低您网站速度的元素。

Elementor是一款功能强大、灵活的WordPress页面构建器，使用它可以轻易搭建出时尚、功能强大的响应式页面，因此备受欢迎。Elementor功能很强大有众多小部件可以实现各种功能和排版，而且设置多种多样很人性化。然而大家在使用Elementor的过程中，或多或少都会遇到各种小问题和错误提示，本文为大家汇总了Elementor常见错误和解决方法。

1、 Elementor小工具面板加载失败

最常见的 Elementor 错误包括 Elementor 部件面板无法加载。当使用大量插件、多个元素插件或服务器 PHP 内存有限时，Elementor 部件就会停止加载。

解决方法：《Elementor加载缓慢如何解决?》

2、 Elementor内容区域缺失错误

“Sorry, the content area was not found on your page. You must call the_content function in the current template in order for Elementor to work on this page.”（”抱歉，您的页面上未找到内容区域。您必须在当前模板中调用 the_content 函数，Elementor 才能在此页面上运行。）

• 方法 1：换一个主题是最简单的方法。GeneratePress 主题是最兼容 Elementor 主题之一。
• 方法 2：如果不想更换主题，也可以试试这个方法。在页面模板的代码中添加 the_content 函数，只需添加 <?php the_content(); ?> 一行即可

3、Elementor页面空白错误

如果在尝试使用 Elementor 编辑时出现空白页面，可能是因为 WP 内存不足，可以检查网站是否满足Elementor的系统要求。

• 方法 1：增加网站的 WP 内存。
• 方法 2：可以试试这个故障排除步骤。进入 WP 控制面板 > Elementor > Settings。点击 “Advanced” 选项卡，启用切换编辑器加载器方法，然后检查问题是否解决。
• 方法 3：在某些情况下，这可能是因为后端的 URL 与前端的 URL 不同。
• 方法 4：尝试停用任何 Elementor 附加组件或其他插件，看看是否有帮助。

4、如果使用Elementor编辑时出现灰色页面

如果出现灰色页面，可能是由于插件冲突造成的。如何解决使用 Elementor 编辑时出现灰色页面的错误？

• 方法 1：您可以逐个停用插件（Elementor 和 Elementor Pro 除外），然后确定是哪个插件导致了故障，从而解决这个问题；也可以尝试停用 Elementor 附加组件。
• 方法 2：这个问题的根源有可能是浏览器中的某个扩展。为了仔细检查，请尝试使用其他浏览器打开 Elementor 编辑器。

5、无法用Elementor编辑页面错误

如果试图编辑页面，但却一直被重定向到实时页面，这可能有两个原因。要么是插件冲突，要么是内存问题。解决办法如下：

• 方法 1：如果是内存问题，提高网站的 PHP 内存限制。
• 方法 2：可以逐个停用插件（Elementor 和 Elementor Pro 除外），并找出是哪个插件导致了问题，从而解决这个问题。

6、Elementor更改不起效错误

可能会出现这样的情况：您做了更改，但发布时却没有显示样式。出现这种情况可能是因为缓存问题。解决办法可以参考以下5钟办法：

• 方法 1：进入 WP 管理 > Elementor > Tools > Regenerate CSS & Data，即可轻松解决这个问题。然后，您可以清除缓存（WP 缓存和浏览器缓存）并刷新页面。
• 方法 2：检查网站上是否有缓存插件或启用了服务器级缓存。清除这些缓存。
• 方法 3：清除浏览器缓存或在私人/隐身窗口中检查网站。
• 方法 4：这个问题可能是主题造成的。您可以尝试更换为 WordPress 的默认主题，如果问题得到解决，请联系主题的开发人员。
• 方法 5：如果你在使用 Elementor 的同时还使用了其他页面生成器，那么它可能会覆盖你用生成器创建的内容，从而停止显示更改。要解决这个问题，请保存模板，然后将其添加到新页面中，这样就能解决问题了。

7、Elementor发布/更新按钮不可用错误

与大多数问题一样，造成这一问题的原因是内存不足。

方法 1：这可以通过 WP 内存限制来解决，以满足运行 Elementor 的最低要求。

方法 2：有时，当 admin-ajax 脚本超时时也会出现这种情况。要确认这一点，请按 F12 键检查控制台是否出现任何错误信息。如果出现 “加载资源失败：服务器响应状态为 413 “的信息，请在 .htaccess 文件中添加以下指令，以延长动态超时时间。

<IfModule mod_dtimeout.c> <Files ~ ".php"> SetEnvIf Request_URI "admin-ajax.php" DynamicTimeout=150 </Files> </IfModule>

方法 3：这也可能是由于服务器上设置的参数造成的。你可以通过在网站上添加 SSL 认证来解决这个问题。之后，您需要在 WP 控制面板的 Elementor > Tools > Replace URL 中更改网站的 URL。

方法 4：如果尝试更新页面时出现 403 错误，则是由于安全插件造成的。要解决这个问题，请激活插件的学习模块或联系他们的支持。

8、使用Elementor时出现500错误

500错误是服务器问题，您可以自行解决。如果您在使用 Elementor 时遇到 500 错误，必须查看服务器的错误日志来了解问题所在。

• 方法 1：内存限制问题是导致此问题的原因。要满足 Elementor 的要求，内存至少应设置为 128 MB，增加 PHP 内存限制。
• 方法 2：可以停用插件（Elementor 和 Elementor Pro 除外）和任何 Elementor 附加组件，并将 WordPress 主题更改为默认主题，如 Twenty Seventeen，以排除与第三方产品的冲突。

根据国外科技博客TechCrunch的报道，Facebook创始人兼首席执行官马克·扎克伯格（Mark Zuckerberg）在其公司博客上正式宣布，这家社交网站目前用户数已经达到5亿。这对所有人来说毫不奇怪，即便是那些从不关心Facebook公司的人来说也是在预料之中。据扎克伯格称，这个里程碑是在当日上午创造的。不管怎样，Facebook确实与用户一起创造了奇迹，包含了一个个鲜活的故事 ，详细描述了这家社交网站对他们生活的影响。

此外，Facebook也收集一本包含很多感谢之词的相册。Zuckerberg 将会在当晚出席美国广播公司的 “世界新闻”节目接受主持人Diane Sawyer 的采访，详细解述这一重要的里程碑。

试做一个分析：仅仅是在五个半月前，当Facebook在庆祝其成立六周年时，其活跃用户达到4亿 – 目前是5亿，3亿到4亿的时间与4亿到5亿的时间差不多。这能否意味着到今年年底Facebook的用户数能增长到6亿呢，还是说这就是顶峰了呢？

Zuckerberg实际上非常有信心用户数会在某个时候达到10亿，就在上个月举行的 Cannes Lions国际广告节上，他就宣称 ：那是“几乎保证会发生的”。

Facebook最近终于同意引入OpenID。 这意味着，如果得到网站许可，你不仅可以用Gmail账户登录Facebook，还可以顺便登录任何一家使用Facebook Connect的网站，这其中甚至可能包括你的博客。

要达到以上目的，首先要将Facebook账号连接到某个OpenID服务提供商。 Inside Facebook的Luke Shepard接受采访时主要谈到了Google账号的连接。用户需要在自己的Facebook设置中将Google添加为可连接服务。

Shephard说到：

我们致力于为Facebook平台和Facebook Connect提供身份认证服务。 由于OpenID开发上的技术难度，目前支持OpenID后台自动登录的网站还不多，但OpenID会成为Facebook Connect开发历史中的重要财富。

Shepard还提到，Yahoo和Microsoft都在尝试寻找OpenID的解决方案，不久后他们也可能与Facebook开展相关合作。

对OpenID来说这应该是个好消息。 Facebook具有强大的品牌效应，但目前也展现出了衰退的趋势。 此次他们引入OpenID的目的显而易见，不过这也是网站发展的手段。 Facebook究竟会怎样发展，让我们拭目以待。

Faster time to enter the market, reusability of components, the richness of design, programming and debugging tools are just some of the reasons why well-known companies chose React to build or rebuild their web applications. Below, I present the list of brands using React and the reasons why it was chosen.

Facebook

Let us start with a curious detail: Facebook is the place where the React.js library was created. Its author is Jordan Walke, a Facebook software engineer who developed a prototype called “FaxJS”, and who was inspired by library components for PHP.

At this point, it should be noted that Facebook is not only a social platform but – above all – a technological company whose goal is to develop technology and share resources with its users. Thus, React turned out to be a way to involve more developers in relation to open source also.

When can you see the functionality for which React is responsible on Facebook? Especially when the key elements of a page load immediately when it is being updated. Thanks to this, you receive the updated information. This is reflected, for example, when the latest update, comment or like of a friend from Facebook appears – as you know, there is no need to reload the entire page. You can interact then, click “Like”, “Share” buttons, etc. – and still get an immediate response from a webpage, without having to load a page.

Atlassian

Atlassian is a world-famous Australian brand that owns, among others, such products as: JIRA, Confluence, Bitbucket, Trello, Hipchat. And almost all of them are being built using React.js.

Atlassian used key React functions to easily introduce changes on all devices: desktop, Internet and mobile ones.

Atlassian experts argue that there is an exciting future lying before React, both in terms of opportunities for developers, but also because of the growing interest in it.

UberEats

Most people probably know this brand, but maybe not everyone knows that browsing, ordering and tracking orders is the result of using React.js.

Thanks to it, the restaurant dashboard was developed, which can be accessed via smartphones or tablets. The UberEats team decided that restaurants need a seamless way to communicate with both suppliers and consumers.

They wanted a solution that would meet various requirements, including:

• placing a new order,
• accepting an order,
• arrival of a delivery man, 
• execution of an order.

The most important, however, seems to be the fact that React has made it possible to improve the user experience of the web application, which you can see for yourself when using the application.

Netflix

The absolute leader in its line of business. In 2015, Netflix used React to redesign its UI. The decision came from the need for improving:

• launching speed, 
• performance, 
• modularity. 

Over the course of five years, the website has undergone numerous changes and updates, but React remains the main tool for creating its front-end.

Thanks to the user-friendly interface, you can easily go through the authorisation and logging-in process, and the intuitive website design, as well as the convenient filtering, help to find what users are looking for. The application includes many features for content management: Ultra HD 4K, HDR, Dolby Vision, Play Netflix.

Airbnb

Component reusability was also an argument for Airbnb’s choice of React. The Airbnb developers have actively contributed to the development of the entire React ecosystem, which resulted in creating the React Sketch.app library. It is a library that aims to serve as a support bridge for cooperation between some design works and programming works. The React components are responsible for rendering documents in Sketch.

Dropbox

Starting in 2012, the developers at Dropbox began taking steps to improve the service. At that time, one of the problems was the fact that many engineers contributed to the codebase, but only a few were aware of what was actually going on within the website. In 2016, React was selected in order to start redesigning the library.

Have you noticed how quickly you can preview any document at Dropbox? When gathering file data, React analyses the number and size of pages, visualising a preview as the page is being scrolled down. The Dropbox team used a combination of React and other JS tools to ensure smooth operation across all browsers.

Codecademy

The company offers coding courses, including such languages as: Java, Python, SQL, C ++. It is a well-known educational platform.

React is an integral part of the library; it is one of the key scripts integrated with the Codecademy structure – the header, menu and navigation among them. Arguments for using React, pointed out by Codecademy, were its ease of use, SEO-friendliness, and flexibility.

In addition, it is great for front-end building and interfaces development with JavaScript. In addition, it should be emphasised that animations are also created using React, and it is worth noting that they will appear with minimal coding. The company really wanted the interface to remain as attractive as possible.

Skyscanner

Moving on the topic of design, another example is a website – and more precisely a large internet search engine – enriched with information about flights around the world.

In 2019, Skyscanner decided to redesign so widely that the development team created an entire design system – Backpack. This is important enough to mention because this system is based on React components. The main goal of the developers was to create a coherent, clear interface for all users. The programmers wanted the UI/UX design and the brand appearance to be impeccable.

Zendesk

It is a software development organisation that offers SaaS solutions with features such as tracking, problem monitoring, help desk management and customer service. The company is committed to ensuring easy and effective communication with its clients.

Zendesk is the author of Garden – a system to assist with design. And it was in Garden that React components and tools were used to offer visualisation, localisation or navigation.

Summary

Companies eagerly adapt to the technologies thanks to which they can shorten the time of entering the market with a new product. This is an extremely important argument in the context of business and expected profits. The issue of technology stability is essential here, especially in a situation where other technological solutions appear and disappear.

As I mentioned in the introduction, React comes with a rich suite of design, development, and debugging tools. The React developer tools are available for some browsers such as Chrome and Firefox. With React, you can reduce wasted time, improve user experience, and provide better application performance.

As you can see in the examples above, React is one of the most popular and reliable front-end frameworks used by many companies. That is why at Droptica we put an emphasis on the React.js development services, and most importantly – we know how to use React.js with Drupal.
