The formed active material in the stamped grids becoming loose in the grid openings and the battery failed . 冲孔板栅形成后的活性物质在板栅的孔中变得松散,因而使蓄电池失效。
The broad fluorescence spectrum of the organic dyes suggests a broad tunability range for lasers using them as the active material . 有机染料具有宽荧光光谱使人们想到,若用它们作为激光介质,则激光器就会有宽的调谱范围。
Positive active materials of lithium manganese oxides for lithium - ion batteries 4电池材料的研究现状
Lifepo4 as the cathode active material for lithium ion battery 锂离子电池正极材料掺杂稀土的研究进展
The pure active material can be sintered in 5 hours by using solid - state method 用高温固相法5h就能合成出纯相活性物质。
