摘　　要：基于弹性平面问题的多项式解析解，构造出一种新的拟协调平面四边形单元──ＡＱＣＥ单元。算例表明该单元具有计算量小、精度高、便于应用的优点。Based on the polynomial analytical solution of elastic plane problem , a new qusi-conformedplane quadrilateral element which is named AQCE element is presented. Numerical examplesshow that the method with convonient applications requires less time-consuming and calculatedresults have higher precision.
