2022 年5 月挖机行业销量20,624 台，同比-24.2%，基本符合此前CME 预期-23%，较4 月-47.3%降幅趋势明显。其中国内销量12,179 台，同比-44.8%；出口8,445 台，同比+64.0%，出口持续向好，销量在总销量占比提升至40.9%。2022 年1-5 月挖机行业累计销量122,333 台，同比下降39.1%。其中，国内市场销量80,097 台，同比下降54.7%；出口销量42,236 台，同比增长75.7%，在总销量中占比34.5%。5 月挖机行业降幅较4 月明显缩窄，主要原因是同期高基数压力缓解、出口增长强劲，展望未来，随着疫情逐步可控，基数进一步稀释，行业降幅进一步有望缩窄，三季度有望迎来转正。

军工“内生”需求将中期高增长。世界进入新一轮装备扩张期；为“备战”打战、实现百年强军目标，建立与经济相称的国防，军工装备进入5-8年高增长期。行业“外延”增长锦上添花。2022年是国企“三年行动计划”最后一年，国资委再提“加大优质资产注入及股权激励力度“，军工集团不断推出重组案例。

Chillers are devices that eliminate heat from a fluid through a vapor-compression or absorption refrigerant cycle, and discard that heat elsewhere. Cool fluid generated by the chiller is dispersed within a heat exchanger to cool and dehumidify fluid in various commercial, industrial, and medical facilities. In addition, ice cold water is utilized for different industrial applications, which include food processing, patient cooling, equipment cooling, and others.

Transmission is a component inside the vehicle, which is installed to transfer mechanical power from the engine for spinning the wheels. Electric vehicles are generally installed with single-speed transmission. However, leading players in the electric vehicle (EV) transmission market are launching new multi speed transmission with added features for high performance and efficient energy conversion. Electric vehicles with multi-speed transmission offer better performance than single-speed transmission systems in terms of faster acceleration, top speed, gradeability with driving range, and others.

A commercial boiler is a pressurized system that creates heat by burning combustible fuel to provide heating for residential and commercial buildings. Burner, combustion chamber, heat exchanger, controls, and exhaust stacks are just a few of the components that make up a commercial boiler. These add-ons are essential for a commercial boiler's optimal operation. However, due to efficient operation of commercial boilers, regional governments have mandated the installation of safety accessories in commercial boilers under the Code of Federal Regulations (CFR) and the India Boiler Regulation (IBR).

Though not officially recognised by SAE under SAE levels of autonomous driving, L2+ is a new level of autonomy, adopted by the automotive industry, which bridges the capability and requirements gap between Level 2 and Level 3 automated driving. Over the next few years, L2+ is expected to enjoy a larger market share than L2 and L3 have. The higher adoption of L2+ will provide a larger number of consumers, with access to and acceptance of automated driving systems.

美国总统拜登今年3 月16 日宣布将向乌克兰提供8 亿美元 额外军事援助，其中包括100 个“弹簧刀300”巡飞弹。此后陆 续提供了多批，数量已经达到400 枚。4 月21 日美国又宣布了新 一轮对乌克兰8 亿美元军事援助，其中包括121 套“凤凰幽灵” 巡飞弹，据称该弹是美国专门为乌克兰研制的定制版。巡飞弹是 无人机技术和弹药技术有机结合的产物，可看作是“自杀式无人 机”，或者是“可以飞行并锁定目标的手榴弹”。
