Solid-state transformer (SST) is an advanced power converter that offers bi-directional power flow, which makes use of power electronic components. These transformers are also known as solid-state transformers, such as universal power electronics, intelligent universal transformer, energy control center, and power electronics traction transformer. However, the most common term used to refer SSTs is smart transformers. The concept of solid-state technology has been getting attention in the recent years as a direct result of advances in power electronics, smart grids, and growth in application sectors such as renewable energy generation.

苏联解体后，俄罗斯的文化政策主要经历了三个发展阶段。当前俄罗斯已经形成了较为完备的文化政策体系。《国家文化政策纲要》和《2030年前国家文化政策战略》等法律文件从法律概念层面将文化提升为国家优先事项，将其视为保证统一文化空间和俄罗斯领土完整的最重要因素之一，文化政策具备了国家战略意义。国家项目“文化”是俄罗斯执行文化政策的具体方案，规定了文化政策具体开展的方式以及资金资助内容。2020年新冠肺炎疫情肆虐全球，俄罗斯也深受其害，国家项目“文化”的执行受到了一些阻碍，但在俄文化部和各部门的努力下，国家项目“文化”的各子项目并未停滞，有些项目甚至超额完成。

Tower cranes are mostly fixed and offer heavy lifting and handling operations on very high heights. These cranes constitute of a vertical mast and an operating jib or arm, along with other components including, a counter jib, an operating cabin, slewing unit, hoist winch, and a hook, which assists in lifting and maneuvering heavy materials and goods efficiently. The report on the global tower crane market presents a detailed analysis of the trends, future estimations, and thorough study of the market on the basis of type, lifting capacity, end-user industry, and region.

农牧业是人们利用太阳能、依靠生物的生长发育来获取产品的社会物质生产部门。其本质是人类利用有机体的生命力，把外界环境中的物质和能量转化为生物产品，以满足社会需求的一种生产经济活动。农牧业是提供人类生存必需品的生产部门，同时也是一个弱质产业。改革开放初期，我国在农村实施了家庭联产承包责任制，这项制度设计激发了农民的生产积极性，解放了劳动生产力，大大提升了农业的单位产出量。但由此而来的问题也在不断显现，随着计划经济时代被抑制的农村劳动力潜能的释放，家庭联产承包责任制下的农业产出逐步达到了它的极限，“统分结合”中过于偏重“分”的经营模式，越来越不适应现代农业的低成本、高效率、重生态的要求。实现农牧业现代化、提高农牧业的比较收益成为民族地区发展农牧业的必然选择。

锂电设备作为生产工艺设备，直接决定了电池的品质和一致性。电池生产工艺大体上其工艺流程可分为前端工序（极片制作）、中端工序（电芯制作）以及后端工序（化成分容及电池组装）。前、中、后段设备的价值量占比分别约为35%、30%、35%。其中前、中、后段工艺最核心、价值量也最高的设备分别为涂布机、卷绕/叠片机、化成分容柜。
