摘 要：
微分方程的平衡点可分为稳定和不稳定两种。当轻轻扰动平衡点时,系统状态就会剧烈变化。若新的状态决不会回到原平衡点,此点就是不稳定的;相反,如果一个系统在稳定平衡点附近受到干扰,它总是企图回到平衡点,那么此点就是稳定的。用这一数学工具可以解决诸如渔场鱼量等一系列实际问题。

摘 要：
Balance solutions of a differential equation are steady solutions that represent steady condition of a system. Balance solutions can be divided into steady spots and unsteady spots. When solutions just change slightly, the system will digress drastically from the original condition ,in this circumstance ,these solutions are unsteady spots of the system. Steady spots are in contrary.
