1·In the process of automobile engine gear, the scheme of gear blank processing and the determination of the gear shaving parameter are the main factors that affects the gear teeth processing.

在汽车发动机齿轮的加工工艺中，齿坯加工方案和齿轮剃齿参数的确定，直接影响齿轮齿形加工的主要因素。

2·The results show that the determination system is within the scope of widen wave length with low absorbency in blank solution and high absorbency in working solution.

结果表明，这些体系均存在空白液吸光度很低、工作液吸光度较高的较大的波长区间，是分光光度分析法中理想的测定体系；
