指出劈尖等厚干涉实验中随着膜厚的增加，条纹间距变大。
In the experiment of wedge shaped interference, the fringe space becomes wider as the thickness of the membrane increases.
随着光束间距的增大，干涉条纹间距减小，条纹数目增多，条纹可见度减小；
With increasing beam separation, the number of interference fringes increases and the fringe separation and visibility decrease.
光束束腰半径增大时，干涉条纹数目增多，条纹间距变化很小，对条纹可见度影响不大。
With increasing beam waists, the number of interference fringes increase, but the fringes separation and visibility change little.
