我们同意您的观点，当存在外加磁场时，等离子体出流实际上更快，因此速度剪

We agree with your point of view, when there is an applied magnetic field, the plasma flow actually faster, so the speed shearing stronger. With or without an applied magnetic field, we see similarly shaped vortex within the initial several KH Al modulation period, and in FIG. 5 (a), the simulation results are more or less all exhibit the same slope. But it will shear layer such that the speed is reduced in the presence of an applied magnetic field (KHI Evolution region) does not cause the rear of the Al layer KHI modulation generated. We redrawn in FIG. 2, we have now clearly seen from FIG. 2 (c, d), formed to have more than the number KH I have obtained the case where no external magnetic field applied magnetic field. This is a result of the stabilizing magnetic field applied.

We agree with you that when an applied magnetic field exists, the plasma flows out faster, so the speed is sheard more. With or without an applied magnetic field, similar-shaped KH vortexes are seen during the first few Al modulation cycles, and in Figure 5(a), all simulations show more or less the same slope. However, the presence of an applied magnetic field causes the velocity shear layer to become smaller (the evolution of KHI) causing no KHI generation on the latter Al modulation layer. We redrawn Figure 2, and now it's clear from Figure 2 (c, d) that there is no applied magnetic field that produces a significantly higher amount of KH than there is an applied magnetic field. This is the result of the stabilization of the applied magnetic field.

We agree with you that when there is an external magnetic field, the plasma outflow is actually faster, so the velocity shear is stronger. No matter whether there is an external magnetic field or not, KH vortices of similar shape can be seen in the initial several al modulation periods, and in Fig. 5 (a), all simulation results show more or less the same slope. However, in the presence of an external magnetic field, the velocity shear layer becomes smaller (the evolution region of khi), resulting in the absence of khi on the subsequent al modulation layer. We have redrawn Figure 2. Now from Figure 2 (C, d), it can be clearly seen that the number of KHS generated when there is no external magnetic field is significantly more than when there is an external magnetic field. This is the result of the external magnetic field.
