quadrature component meaning in English

正交分量

If we can prepare a mode of the electromagnetic field in an appropriately squeezed state , it will allow one to tune the signal - noise ratios of its quadrature components : one of the quadratures can be used to absorb the inevitable quantum - mechanical " noise " , while the other one serves to transmit an extremely well - defined signal
如果将电磁场的某一个模式制备在压缩态，那么就可以调节信噪比，使得一个正交分量可以用来吸收不可避免的量子力学噪声，另一个正交分量用来很好的传递信号。那么在量子电磁场中当系统的一些模式被制备在压缩态时，就很有必要研究场的腔性质了。
