纵[横]向极化
The breakpoint is determined mainly by the frequency and nearly independent of the transverse dimensions of tunnels and the polarization modes. The greatest stress is found at the location on the cross section where V is the largest.
电导率断点主要受传播频率的影响,而与巷道横截面尺寸和极化方式几乎无关。最大应力出现在横截面上v为最大的地方。
We also measured the polarization by using the polaroid which is made of parallel metal lines, the transverse intensity distribution of modes by using thermo-electronic detector, and compare it with theoretical calculation.
用热释电探测器横向扫描测量了远红外激光的横向强度分布,并且与理论值进行了比较。
