But their piezoelectric property is poor. Several processings, grain orientation growth ( TGG) and doping, which can improve performance of the bismuth layer structure lead-free piezoelectric material, are introduced.
本文重点介绍了提高铋层状结构无铅压电材料压电性能的措施&晶粒定向生长和掺杂。
At high temperature melted Al spread over the TiB 2 particle surface, which lead to a decrease of reaction layer thickness of melted Al, an increase of reaction surface and speed, and liquid sinter occurs.
在反应区高温下熔融Al在TiB2表面发生漫流现象,使Al的反应层厚度减小,反应面积增大,反应速度提高。
The design of 10 900L constant temperature stainless fermentation tanks with insulating layer was in the lead domestically, as well as the saccharified boiler and the filtration-deposition trough.
设计的10个900L高性能保温恒温不锈钢发酵罐及麦汁制备的糖化锅和过滤沉淀槽,其设计在国内是领先的。
