例句與造句

1. This device splits the light beam into a measuring light beam and a reference light beam .
   此設計把光束分成測量光束和參化光束。
2. Be different with other botdr systems , the coherent self - heterodyne botdr system uses only one consecutive laser . the light from consecutive laser is divided into two beams , the detecting light and the reference light , by a coupler
   與其他的botdr系統(tǒng)分別使用兩臺激光器不同,自相干外差的布里淵散射分布式光纖傳感系統(tǒng)采用一臺激光器,經耦合器分為兩路光束? ?探測光和參考光束。
3. At the same time , it uses a frequency translator to obtain a frequency shift , which is equal to the brillouin frequency in fiber . then the detecting pulsed light and the cw reference light can coherent . this method greatly improved the system ’ s sensitive and signal to noise ratio ( snr )
   同時在探測光路中引入一個光移頻環(huán)路,使探測光移頻后再經光纖中布里淵頻移,其后向布里淵散射光頻率與參考光束大致相當,可進行相干自外差探測,大大提高了系統(tǒng)的探測靈敏度以及系統(tǒng)的信噪比。
4. It's difficult to find reference light in a sentence. 用reference light造句挺難的
