Moreover, for some Special cases, it is proved that there exists unique equilibrium solution and it is global asymptotically stable.

在适当条件下，证明了平衡解方程有唯一解且是全局渐近稳定的。

For the calculation problem of column stability set forth in this paper, there exists a trouble that the conventional solution cannot satisfy the equation of equilibrium.

对于文中列举的一道压杆稳定性计算题，其常用解法中存在着不能满足平衡方程的问题。
