强激波

For instance, the perturbation may transform a strong detonation into a weak deflagration followed by a shock wave. This interesting phenomenon also appears in the numerical solutions in [58]. Our results give a reasonable explanation to this phenomenon.

例如，扰动会将一个强爆轰波变为一个波后为激波的弱爆燃波，这种现象亦出现在数值解[58]中，我们的结果为这种现象提供了一个理论的解释。

The evolution of the half-peak width of the relative density increment pulse with respect to slow wave also demonstrates the close relation to Δp. Its minimum w〓 decreases with the increase of Δp, which means, slow wave will steepen with the enhancement of Δp and may evolve into slow shock eventually. Numerical results also indicate that the propagation velocity of fast and slow wave increase when Δp increases.

对强扰动情形(Δp＝5)，通过考察相关物理量的径向分布，并借助于对物理量沿波动阵面法向分布的讨论，可以初步判断出由强扰动所造成的慢模磁声波在传播过程中逐渐陡变而演化为慢激波，慢激波在进入日冕前已在色球层中形成，并在此后的传播过程中始终保持这一性质。

It is found thatthe fractal dimension D=1.25 corresponds to the lowest criticalcoupling constant αc=1.9,D=1.73 corresponds to the highest criticalratio of dielectric constants ηc=0.163,and when D≤1.145 bipolaronscan not exist at any rate.In chap,4,we will propose a novelapproach to the calculation of the exciton ground-state energy for thestrong-coupling case.Different from all previous methods,the wavefunction of the phonon part is assumed to take a form related to thewave function of the relative motion.We obtain the exciton energy bysolving the derived integrodifferential equation rather than select ahydrogen-like form to minimize the energy expectation.

结果发现，分数维的维数D＝1.25对应最小的临界的电-声耦合常数(αo＝1.9)，D＝1.73对应最大的临界的介电常数比(ηc＝0.163)，当分数维的维数D≤1.145时，双极化子无论如何也不可能存在，在第四章中，我们将提出一种新颖的变分方法来计算强耦合的激子-声子系统的基态能，不同于以前所有的方法，我们取声子的波函数与相对运动波函数有关的形式，而不是假定一个固定的关于相对运动坐标r的函数形式，得到相对运动波函数所满足的非线性的微分积分方程，我们数值求解这个微分积分方程得到系统基态能，而不是选择一个类氢原子的波函数变分使得能量的期待值最小。

When the shock wave is not strong, the results of the present method agree with the FP results and the experimental data well.
