  • 简介:通过测定化成过程中AA1500型氢镍电池的内压,研究了电池制备工艺参数,如:电池的正负极容量配比、电解液组分及用量、负极导电剂、粘合剂、化成制度等对电池内压的影响。试验表明,电池制备工艺参数对氢镍电池的内压均有很大影响,通过确定合理的制备工艺参数可以有效地抑制氢镍电池化成过程中内压的升高。

  • 简介:高倍变焦以前只出现在高档胶片单反相机中,但自从数码相机出现后,高倍变焦不再是个梦。相对于传统的胶片相机,数码相机的最大弱点是感光元件(CCD或CMOS)的面积太小。很多消费级数码相机的感光元件面积仅是1/1.7英寸或1/2.7英寸甚至更小。不过,这个小型感光元件配上不大的镜头就能够拥有大光圈,现在很多数码相机在35~420mm的范围内都能使用f2.8光圈。
