- 文摘:对于C1的具有任意函数类型的平面曲线，利用分段仿射变换方法，生成近似的等距线.它的每一段与原曲线的相应曲线段具有相同的函数类型，具有仿射意义下的几何性质，能较好的逼近原曲线的等距线.
Abstract: In this paper the segmental affine transformation is used to produce an approximate offset curve for C1 plane curve with arbitrary function.Each segment of this offset curve has the same function form as the corresponding segment of the original curve and has the invariable geometric characteristics under affine transformation,and also it shows a better approximation to the offset curve. - 在写信的正文⑤时，可以有两种格式，一种是顶格式，所有段落首行一律与左边线对齐，另一种是缩进式，所有段落首行均采用首行等距缩进格式。
In the body of the letter ⑤, all paragraphs should begin flush with the left margin, which is the block style, or begin with an equal indentation of two typing spaces, which is the indented style.
