The low solid concentrarion in the circulating suspension bed ( csb ) causes the insufficient gas - solid mixing and low contact reaction intensity 摘要循环悬浮床内固相浓度很低，改善气固混合对增强接触反应、提高脱硫效率起着关键作用。
2.
Ni ohmic contacts fabricated by traditional evaporation and thermal annealing on temperature of about 1000 have lower contacts resistances . the testing result on 400 does n ' t show it can keep thermal stability 按常规方法镀镍( ni )并经1000左右高温退火得到的欧姆接触具有更低的室温比接触电阻，但400高温欧姆特性测试表明其热稳定性不够好。
