So we develop a sort of calibration equipment of the line displacement sensor. 为此，我们研制了一种线位移传感器静态校准装置。
This spectral shift permits laser light to selectively excite molecules containing one isotope while leaving the molecules containing the other isotope undisturbed. 这种谱线位移使我们能够利用激光有选择地激发含有某一同位素的分子，而含有其他同位素的分子则完全不受扰动。
