程序可求解任意边界条件任意力（需手算或增加m文件将力等效到单元节点）的矩形板的单元受力及应力。-Program can solve any power of arbitrary boundary conditions (to be hand or the equivalent increase in m file will force the node to the unit) unit of the rectangular plate the force and stress.

横截面为矩形的无限长槽由三块接地导体板构成，槽的盖板直流电压100v，求矩形槽的电位分布-A infinite long slot, with rectangle cross-section, consists of three grounded conductive plate and one coverplate with 100 voltage. Please give the potential distributions inside slot

平面8节点单元类，可以输出单元的刚度，并可通过形函数插值得到内部各点得位移、应力等。对各位以前编写的程序的一个补充和完善吧。(plane eight-unit category, the output unit stiffness, through the shape function can be interpolation points in the internal displacement and stress. Right before you and the procedure fo

计算矩形平板的声辐射特性，该平板为有障板的矩形薄板，考虑板在水中的声振耦合问题(CALCULATION OF ACOUSTIC RADIATION CHARACTERISTICS OF RECTANGULAR PLATES)

矩形板是一种常用的结构，针对有限元原理，运用matlab对他进行了编程。(Rectangular plate is a commonly used structure, for the finite element principle, the use of matlab on his programming.)
