Question

请高人帮忙翻译一段话（有点难度），要专业的！翻译工具的就不要拿出来了！翻译好再加分！谢谢！

这是因为对于一个给定的扇叶位置，当射频能量传送到腔体的边角，就会被混波室侧壁、顶面、底面和扇叶所反射。所以在混波室内某点的电磁场是来自各个方向反射波在这一点的矢量和。而扇叶的旋转改变了电磁波抵达这一点的路径长度和波的反射次数。故在室内某点叠加的各个反射波也具有不同的幅度，不同的相位。
图5是混波室中间某一点的电场Ex时间平均后得到的时域变化曲线，图6是矩形空腔中间某一点的电场Ex时域变化曲线。通过与图6比较，可以看出，随着时间的推进，混波室的时间平均电场值波动减小，逐渐趋于稳定，而矩形空腔由于其谐振作用，波形收敛很慢，波动很大。这是由于扇叶的旋转或取了大量的离散位置，影响了原理想空腔的场值变化，谐振效应对混波室内部场分布的影响明显变小。

图6 矩形空腔中间某一点的电场Ex时域变化曲线（57000时间步）

Answer 1

This is because for a given position of the fan, when the RF energy to the cavity of the corner, will be mixing chamber side wall, top, bottom and reflected fan. Therefore, in mixed indoor wave electromagnetic field of a point in all directions from the reflected wave at this point and the vector. And changed the fan rotation of electromagnetic waves that arrive in the path length and frequency of wave reflection. Therefore, superposition of a point in the interior of each reflected wave amplitude is also different, and different phase.
Figure 5 is the middle of Reverberation-Chamber Ex electric field of a point after an average period of time-domain curve, Figure 6 is a point in the middle of the rectangular cavity of the electric field changes in time-domain curve Ex. Compared with Figure 6, one can see, as time progresses, the time Reverberation-Chamber fluctuations reduce the average electric field value, and gradually become stable, while the rectangular cavity resonance due to its role in the convergence very slow wave, volatile . This is due to the rotating fan, or take a large number of discrete locations, the impact of the principle of market value would change in the cavity, resonant chamber mixing effects on the distribution of the internal market significantly smaller.
