不稳定解 meaning in English

unstable solution

Firstly , the integral - differential equation described the radiation field evolution is derived , and then the instability of its solution is also investigated analytically . by using the perturbation and iteration method , the threshold detuning and threshold linear growth rate of the unstable solution are analyzed and discussed in detail
首先，建立了一个描述辐射场演化的积分一微分方程，解析分析了系统解的不稳定性，并采用线性方程解的微扰迭代方法进一步对系统不稳定解出现的失谐量阈值和线性增长率阈值等作了详细讨论。
