【摘要】 本文提出一个改进薄板弯曲单元计算精度的一般性方法：用精化矩阵对原有的单元刚度阵进行修正。实践表明，这种方法可以有效地改变单元的刚柔特性，从而达到提高单元精度的目的。文中证明了，单刚中加进精化矩阵不会破坏原来单元的收敛性质。更多还原

【Abstract】 A general method,namedf refining matrix technique,is presented to improve the accuracy ofa thin plate bending element.It is shown that stiff/flexible characteristic of the element can bechanged efficiently by the method,so the high accuracy is obtained.It is also proved that the con-vergency of the element would not be damaged.更多还原
