例句與造句

1. The spectral intensity can be found via a quadratic equation using the intensity of the dc and ac terms ( filtered independently via a similar method above ) or more commonly from an independent measurement ( typically the intensity of the dc term from the calibration trace ), since this provides the best signal to noise and no distortion from the upconversion process ( e . g . spectral filtering from the phase matching function of a'thick'crystal ).
2. It's difficult to find calibration trace in a sentence. 用calibration trace造句挺難的
