In recent years, it has become one of the important launch methods. Since 2019, China has carried out a total of 11 successful sea launches. The Gravity-1(YL-1) sea launch system consists of a launch vehicle system and a sea launch platform. The sea launch program includes roll on/roll off boarding, sea mooring, sea maneuvering, anchoring and positioning, system testing, and formal launch. Through the maiden flight of YL-1, the design and manufacturing technology of large tonnage dedicated launch ship, launch vehicle vertical transfer and roll on/roll off boarding technology, anti-shake technology for sea launch, simple inflatable flexible insulation protective cover technology, and remote wireless measurement and control technology have been fully verified. 展开更多

With the rapid development of agricultural machinery technology, the quality, reliability and operation ability of our country's independently produced agricultural machinery products have been significantly improved. The functions of agricultural machinery products have been continuously enriched and the driving experience has been significantly optimized. Under the situation that the state strongly supports the development of agricultural mechanization, the state and local governments have launched a large number of policies to support agricultural machinery. The implementation of subsidies for the purchase and operation of agricultural machinery has significantly improved the cost input and actual income in the process of agricultural production and operation. Farmers' purchasing ability and enthusiasm for the use of new technology agricultural machinery have been continuously improved. The good situation of agricultural mechanization production has promoted the development of agricultural machinery production enterprises. Many new agricultural machinery products are further combined with advanced automation technology and information technology, so that the agricultural machinery products gradually have the characteristics of automation and are developing towards high technology, which has a positive role in promoting the improvement of the level of agricultural mechanization and the development of agricultural economy in our country. 展开更多
