The isotherm was devided into three different sections, at low pressure it is concave, at high pressure it is convex and the middle section it is nearly linear.
得到的吸附等温线分为三个不同区域：低压区等温线对压力轴呈凹形，高压区呈凸形，中间部分近似为直线。

Current density low, sedimentary speed is slow, prone to Yin and Yang, the luster of the poor, face Current density too high, convex department easily burnt.
电流密度低，沉积速度慢，容易出现阴阳面，光泽欠佳；电流密度过高，凸部易烧焦。

As to their applications, some results about the low control theorem of the convex lower semi-continuous function and the subdifferentiable function theorem are obtained.
