[求助] 请帮忙翻译两句话(汉译英) 谢谢

这个椭圆的长短轴总在x,y方向,x,y方向恰好是1/4波片的快慢轴方向,因此,从1/4波片出射的光为线偏振光,其偏振方向与y轴夹角为。因此要把检偏镜从正交位置转过角就可使输出极小,这个角称为消光角,该角可由检偏器检测,双折射梯度ΔR可由下式表达:

The long-short shaft of the oval is always in the X, Y-directions, and the X, Y direction is exactly 1/4 wave plate of the fast-slow axis direction. Accordingly, the light emitted from the 1/4 wave plate is named as linearly polarized. Its direction of polarization and the y-axis angle is . Therefore, the analyzer from the quadrature position turned away  angle allows the output is minimal. This angle named as the extinction angle, can be detected by the analyer, and the birefringence gradient ΔR can be showed as follows:
