摘　　要：本文提出采用空气隙错位平晶涉仪测量高密度梯度场,并测量了空气中高温等温热板自然对流的高温度梯度场,计算出折射率的分布。The shearing interferometer with air-gapp between two piano-plates is used to measure both the flow field with high density gradient, and the flow field of natural convection with high temperature gradient beside an isothermal hot plate. The distribution of the-refraction index in the field is calculated.
