并按线性小振幅波理论，导出了改进的透射系数计算式，其计算结果与试验值符合良好。
A modified transmission coefficient formula is derived based on the linear small amplitude wave theory, and calculation results are in good agreement with the test results.
满足夫琅和费远场条件的两个物体，z值大的物体将被环数少的菲涅耳波带板扫描，具有小而平直的孪生像噪声振幅；
In the far-field, the further object scanned by FZP with fewer fringes has flatter and lower amplitude of twin-image noise for reconstructed image.
随刺激频率增加，负向波潜伏时延长，而小正向波振幅逐渐减小。
Increasing flash frequency increased latency time of the negative wave, but decreased the amplitude of the small positive wave.
结果显示，小耗散的存在使孤波的振幅和移速随时间缓慢地减小，孤波宽度则随时间缓慢增大；
The numerical results show that the presence of small dissipation causes a slow decrease of the amplitude and the propagation speed of the solitary waves and slow increase of the solitary wave width.
