查询词典 incidence matrix

Projectors and monitoring hydrophones are placed n a chamber along its length. The projectors are driven By the required drives that are calculated aceording to a measured transfer matrix, and amplitude, frequency and incident of the predicted plane wave. Then the acoustic pressure field distribution which is equivalent to the predicted plane wave of any incidence is set up in the chamber. A prototype calilbration system has been developed.

在管中沿管轴方向布置一系列发射换能器和监测水听器，根据实测得到的传递函数矩阵和所要模拟的平而波频率、幅度和入射角计算得到一组发射换能器驱动信号的幅度和相位，然后以此信号激励每个发射换能器，就能在管中形成一个等同于任意角度入射的自由场平面波声场的声压分布。

This paper analyses how the electricity vector orientation of the normal incidence plane polarized light or garden polarization light is altered by quarter wave plate by making use of Jones matrix of polarizer.

用坐标变换法解出偏振器件一般情况下的Jones矩阵，利用偏振器件的Jones矩阵分析四分之一波片对正入射平面偏振光和园偏振光的偏振态的改变，指出获得和判断椭园和园偏振光的方法。

In view of the facts that traditional graphical construction has less pertinence to stray light and tracing different incidence angle rays is fatiguesome and more likely to omit some rays, we proposed a reverse ray-trace method based on the ray reversibility. According to the method, a dot-matrix source was set at the image plane. Each dot emitted rays to fully cover the system aperture. A detector surface, large enough to receive all possible rays from the source, was set at object plane.

针对传统作图法设计遮光罩的针对性不强，且追迹不同入射角的光线繁琐、容易遗漏的问题，本文提出一种逆向追迹法，依据光的可逆性，在像面处设置点阵面光源，每一点都发出充满系统孔径的光束，在物面设置足够大的探测面，使之有充足的余量记录所有到达物方的光线，利用该方法可以在探测面上直观地区分出非成像杂散光。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
