The formulae that didn " t contain fluorine had low rates of corrosion , high stability and easy operation and had distinct improvement in coating quality , surplus of chromium , saving electricity and energy and environmental protection etc . when they were compared with the commercial additive of wr - 1 and the electrolyte formula of fenghui galvanization plant , the results showed that the effect of chromium plating of the formulae obtained in this study are more excellent 所研制的配方，不含氟、腐蚀率低，稳定性好，易操作，在镀层质量、节铬、节电、节能、环境保护诸方面都有明显的改善，并将其与市售的wr 1添加剂和淬惠电镀厂镀铬效果进行了对比，结果表明本研究得到的配方镀铬效果更优良。
How to rescue the jammed people in earthquake as soon as possible is the aim of 05 task of the " tenth five " national key research . this paper discussed a problem of the task research on auxiliary microaudio - optic life explorer and invent a small , light , easily manipulated , saving electricity , auxiliary system which is an indispensable part of optic life explorer and location finder 本文阐述的是05子课题光学生命搜索与定位仪研究下面的子专题? ?辅助声光一体微型探生仪的研究，主要是利用现有的科技成果，研制出一套只有体积小，重量轻，操作简便，省电，携带方便等特点的微型光学探生设备，是光学生命搜索与定位仪不可缺少的辅助系统。
