The characteristics of the diffraction efficiency, compression, cross modulation, and intermodulation intensities are analysed theoretically.

虽然相对来说音量不大，但“交叉调制失真”增加的却是刺耳的不和谐音符。
Even in relatively small amounts, intermodulation distortion adds a dissonant quality that is unpleasant to hear.

多级衍射光所引起的互调光、衍射光的压缩和交叉调制现象直接影响多色光的合成。
Multistage diffraction light produces inter - modulation light, compression and crossover modulation for the diffraction light will directly affect the composition of the polychromatic light.
