不稳定性

Reconstruction problem is affected by noise that the solution is so unstable that other means is needed to resolve the three dimensional problem at many times.

重构问题由于受噪声影响出现解的不稳定性，致使很多时候不得不采用其他的方法来解决。

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.
