用时域有限差分法模拟超宽带脉冲入射时与目标腔体上的孔缝相耦合的过程，用单轴各向异性的完全匹配层吸收边界条件截断时域有限差分网格。

The plasma density scale length decided by main laser pulse in the experiment is suitable for Vacuum Heating, and it is the domiant process for hot electron generation. From the scaling law about hot electron temperature given by VH model, the hot electron measured by experiment was reasonable, the temperature was higher than the temperature given by Rcsonant Absorption scaling law.

从真空吸收给出的超热电子温度的定标率来看，实验中测量得到的超热电子温度是合理的。X射线是各向同性的，X射线产额随入射激光强度的降低而减小，当强度小于10〓W/cm〓时，不再有硬X射线产生。

Being of the achromatic color of maximum darkness; having little or no hue owing to absorption of almost all incident light.

最黑的非彩色颜色；因为吸收了几乎所有的入射光而只有很少的颜色或者没有颜色。

Being of the achromatic color of maximum lightness; having little or no hue owing to reflection of almost all incident light.

In Chapter 4 windowed function of data signal processing is introduced and applied to addition theorem, which succeeds in solving the difficult problem: it has a bad result when recursive T-matrix is applied to calculate the wave scattering of electrically large objects and multiple objects in the excitation of TE wave.

在第四章中引入数字信号处理中的窗函数，成功解决了在入射波为TE波时，用递推T矩阵法计算电大尺寸物体或多个散射体时，精度不高的问题。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
