摘　　要：以试函数拟合压杆挠曲线 ,用加权残值法求得临界载荷近似值 ,结果表明 。Using the mode of trying function to quasi coincidonce depression bar bine of deflection and the method of weighted residual to evalate the approximation of critical load, we can get the result that the precision of the approximation has something to do with the level on which the trying function approaches the skew curre.
