介绍两种低压电器新的限流技术，粉末颗粒分断技术与液体金属限流器。
The two kinds of new technologies for current limiter: powder based breaking technology and liquid metal current limiter were introduced.
这项新技术的基本原理就是将充满液体的微小胶粒渗入金属外的保护层。
The basic idea of the new technology is to infiltrate this coating with tiny, fluid-filled capsules.
直接还原是一种以气体、液体燃料或非焦煤为能源，使用球团矿、块矿、粉矿在固态下进行还原生产金属铁的炼铁工艺技术。
Direct reduction is an iron smelting process for producing metallic iron using gas, liquid fuels and non-coke coal as energy to reduce pellets, lump ore and fine ore under solid state.
