| 摘 要： | 从常数到变量的飞跃,从定曲面到变曲面的探索,前景乐观.本文由电镀并简化为二维情形引出含双参量的变化闭曲线.通过建立法微分等概念,使变闭曲线的变化性状可用多元微分加以处理,建立了电镀公差估计及优化参数的微分基础,并导出有关性质.

| Abstract: | Tn this paper, a closed curve varied with both parameters has been introduced by means of a practical example of electroplating simplized in a plane. With the help of definning some Concepts such as the Normal Differential, it is made possible that the change behaviors of the varied closed surve may be deseribed in terms of calculus of functions with several variables. By it we could establish the differential foundations for estimation of the tolerarse anu optimization of parameters in electroplating. Further we have proved a series of Properties of the Curves. |
