there is vapor pressure lowering.

蒸汽压的下降。

so, that means that the vapor pressure above the solution is lowered. so i should have said vapor pressure lowering.

这就表示溶液上的，蒸汽压下降，所以这就是刚才说的饱和蒸汽压下降。

the rotation of compensator can cause the change of optical pathlength, and the number of interference fringes will change simultaneously.

补偿板的转动会引起光程差的变化，产生干涉条纹数目的变化。

with increasing beam waists, the number of interference fringes increase, but the fringes separation and visibility change little.

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 separation, the number of interference fringes increases and the fringe separation and visibility decrease.

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；
