直角密集台阶轧齐曲线

本文在分析具有密集性质的直角台阶轧齐问题中，提出里台阶轧齐曲线相对独立，外台阶轧齐曲线受里台阶影响，并形成某种叠加的基本设想。逐个分析了密集台阶存在的四种状态，推导出各种状态下每个台阶的轧齐曲线方程，并给出了各种状态的判别式及各方程的区间。文章最后以简图方式汇总了各种状态，并用例题归纳了计算步骤。

THE SHAPING CURVE OF DENSE RIGHT ANGLE STEP

In this paper, the basic concept was put forward as analyzing the shaping curve of right angle step that possess the quality of density. Its contents are that the shaping curve of inside step is relative independence, and the shaping curve of outside step is affected by the inside and formed a certain complex. The four kinds of conditions of the dense steps were studied one by one. The equations of per step shaping curve at each condition were deduced, the discriminants of each conditions and the domains of definition of each equation were presented. At the article last, the every condition was gather together with the sketch, and calculating methods was summed up in example.
