However, the solutions of the Cauchy problem of the nonlinear hyperbolic system generally develop singularities in finite time even if the initial data are small and smooth.For this reason, solutions must be found in the space of discontinuous functions. Therefore, one can not directly use the classical analytic techniques that predominate in the theory of partial differential equations of other types. Instead, we construct approximate solutions via the singular perturbation methods. By using the compactness of the approximate solutions, we can obtain the existence of the solutions of original system.

然而一般而言，即使是在初值很小且光滑的情况下，非线性双曲型守恒律的Cauchy问题的解在有限时间内也会出现奇异性，为此，我们必须在不连续函数空间中寻找上述问题的解，因此对这类问题的研究，我们也不可能直接利用在其它类型的偏微分方程中占主导地位的解析方法来解决问题，而是通过奇异扰动法构造近似解，由近似解的紧性得到原问题解的存在性。

They didn t study the detailed stability: irreducibility, regular, positive Harris recurrence, and unstability: non-positivity. In the paper we study the drift criterias of these forms of st...

本文利用Drift有关的判别法来给出这些性质的判别条件、 PDMP最初是由Davis引入，其引入的PDMP的首次跳时的分布函数要求必须是绝对连续的，本文是针对刘国欣推广的PDMP模型。

In addition, this article took the isoclinic information which unwrapped already into isochromatic formula to get the correct retardation. This method might not get the form of arc-tangent because there are not output quarter-wave plates in three and six phase-stepping methods. Therefore, this paper corrected it by load-stepping method.

另外，为了使相位展开技术能顺利完成，进而得到相对的延迟量，在修正等色线包裹相位图中的不连续点时，本文使用之方法是将修正完的正确等倾线数值带入等色线公式中，此法在三场与六场中因为少掉了输出的四分之一波板，造成公式的结果使得条纹角度分布非反正切形式，因此需另外使用负载相移法来做修正。
