supporting plane

One plane of the rear-floor strengthening beam is a rear spring supporting seat surface, the rear spring is installed at the lower surface of the rear spring supporting seat surface;

所述后地板加强梁上的一平面为后弹簧支座面，后弹簧安装在后弹簧支座面的下表面；

Under earthquake action, the low-side and high-side supporting columns interact through space truss, so the holistic structure has generality of space truss as well as individuality of space truss with inclined plane.

地震作用下，带斜面的网架下部低端和高端支承柱通过网架相互作用，带斜面的网架整体结构受力时既具有普通网架结构的共性，又具有斜面网架整体体系的特性。

When supporting, as far as possible face plate's working surface will adjust in the horizontal plane.

支承时, 尽量将划线平台的工作面调整到水平面内.

With the method of formal description of plane geometry graphics, an electronic whiteboard supporting intelligent drawing of dynamic geometry on Web is implemented based on SVG.

通过平面几何图形形式化描述方法，利用新型网络图形标准SVG实现了支持Web动态几何智能作图的电子白板。

Base on the basic theory of finite-element analysis, hypostatic modeling for four-side simple supporting plank was upbuilt with ANSYS software. Three-dimensions hypostatic model and plane model were present by simulating the strain distribution of four-side simple supporting plank with damage using finite-element analysis software.

介绍了有限元分析的理论基础，用ANSYS软件对四边简支板试件进行了实体建模，比较了三维实体模型和平面模型特点，并指出了采用平面模型进行建模的合理性；
