有几个专门用于线性图表的折线图选项，如标记(显示数据点)、张力(使直线弯曲)和阴影(给每条线一个下拉阴影)。

There are a few line chart options that are specific to a linear chart, like markers (show data points), tension (make the lines curvy), and shadows (give each line a drop-shadow).

本文根据几何非线性有限元理论，提出张力膜结构初始形态分析的8结点曲面四边形等参单元。

Based on the geometrical nonlinear finite element (GNFE) theory, a curved quadrilateral isoperimetric element with 8 nodes for initial form analysis of tensile membrane structures is presented.
