The interfaces electric circuit and the control program can be transplantated to other micro voltage control equipment very easily.Then we take the C_2H_5Br and the hydrogen (H_2) as the source gas to deposite the gradient bromating amorphous hydrogenated carbon film in the improved low-pressure plasma polymerization unit.

然后在改进的低压等离子体聚合装置中以溴乙烷(C_2H_5Br)和氢气(H_2)为源气体沉积了掺溴非晶碳氢薄膜和梯度掺溴非晶碳氢薄膜，用Perkinelmer Lambda12型紫外／可见分光光谱仪测量了样品的透光谱，并利用透光谱计算了薄膜的光学厚度和光学带隙：利用NICOLET MX—1E傅立叶变换红外光谱仪和XSAM800型X射线光电子能谱仪分析了薄膜的化学键和结合态以及薄膜中氧碳元素比和溴碳元素比。

This paper describes the concaved gear tooth profile after shaving resulting from the unbalance of cutting forces due to the variation of numbers of contact points acting on the teeth flanks, during backlash-free meshing engagement between the shaving cutter and the gear workpiece.

本文认为剃齿齿轮产生齿形中凹现象的主要原因是由于剃齿刀和齿轮在无侧隙紧密啮合过程中，因两侧齿面接触点数量的变化引起切削力的不平衡而造成的。
