Chinese firm delivers self‑developed core casting for world's most powerful onshore wind turbine_我的网站

一 |     与2021年的更新一样，12.9英寸的iPad Pro采用了Mini LED显示技术，以提高黑色水平、更好的对比度和HDR性能，而较小的型号则坚持实用配置较低的屏幕，但两者都支持苹果的ProMotion功能，刷新率最高可达120Hz。新款iPad Pro保持了苹果公司自2018年以来一直使用的整体设计，当时该公司首次取消了Home键，以最大限度地扩大显示面积。但很难说这是一面"全面屏"，因为四面仍有明显的边框，持续四年的外观设计依然持续至今。

The core castings for the world's most powerful onshore wind turbine in terms of single‑unit capacity have recently been delivered by a Chinese company, marking a technological breakthrough in the large‑megawatt onshore wind power castings, domestic news portal stdaily.com affiliated with Science and Technology Daily reported on Wednesday.
Independently developed by Dalian Huarui Heavy Industry Group Co., Ltd. (DHHI), the delivered components include the bearing housing and base castings for 15 MW doubly fed onshore wind turbines. The components need to bear the huge gravity, wind loads and alternating loads transmitted from the blades and hub, and transfer the loads to the generator, ensuring steady rotation of the main shaft. 
The products passed all customer inspections and assessments in one go and were officially delivery, stdaily.com reported.
Adopting an advanced modular design, the turbine components delivered can support flexible power adjustment ranging from 13 MW to 16 MW, enabling adaptive operation to varying and complex wind conditions across diverse regions, the report said.
The turbine's rotor diameter ranges from 240 meters to 260 meters, and are compatible with tower heights of 135 meters to 190 meters, delivering a maximum swept area of 53,000 square meters, roughly 8 standard football pitchs (105m×68m). This places the unit's overall performance among the world's top-tier.
Such super-large castings place extremely high demand on material properties, casting processes, dimensional accuracy and internal quality. The successful validation and delivery of the products therefore demonstrate the research and development, as well as manufacturing capabilities in super‑large wind power castings, stdaily.com reported.

。新款iPad Pro有一个新的 "悬停"Apple Pencil功能，当触控笔稍稍位于屏幕上方时，系统就会检测到它。苹果公司表示，这让用户 "在做标记之前看到他们的预览"。这也让用户能够以更高的精度进行素描和插图，并使用户用Apple Pencil做的一切事情更加轻松。

三 | 例如，使用Scribble时，当铅笔靠近屏幕时，文本字段会自动展开，手写的内容会更快地转换为文本。第三方应用程序也可以利用这项新功能，实现全新的标记和绘画体验。

四 | 苹果公司表示，iPadOS 16是该平台最新的主要软件更新，将在本月某个时候发布。iPadOS落后于iOS 16发布的部分原因是苹果在一个名为"Stage Manager"的新功能上的挣扎，它被描述为"轻松完成多任务的新方法"，在测试期间，一些iPad高级用户对其反应不佳，并被批评为性能有问题。苹果已经对Stage Manager的一些反馈做出了回应，推迟了对外部显示器的支持，并扩大了该功能支持更多iPad型号的范围。M2 iPad Pro支持目前最快的Wi-Fi 6E，下载速度最高可达2.4Gb/s，比上一代产品快2倍。而Wi-Fi+蜂窝型号同时还支持5G（sub-6GHz和mmWave）。新的11英寸和12.9英寸iPad Pro将有银色和太空灰外观，配置为128GB、256GB、512GB、1TB和2TB。11英寸的iPad Pro起价为799美元，现在就可以订购。

五 | M2 iPad Pro将于10月26日星期三上市。
