摘要
从极坐标下应力分量是ｒ、θ的连续函数出发，假设某一应力分量是某一函数对ｒ或对θ的偏导数，找到了直接推导极坐标下不计体力时平衡微分方程通解的途径，给出了两种推导方法，均比惯常的方法简捷直观，从而证明了直接推导应力函数是可行的．
A stress component is supposed to be a partial derivative of a function on r or θ, and many methods deriv- ing directly the general solution of differentiating equations about equilibrium in polar coordinates are found neglecting the forces distributed in volume. The methods are conciser and forthrighter than the conventional ones; therefore, it proves practical to derive the stress function.
