本文综述了一种新的适用于热流数值分析的谱有限差分格式（Fourier展开、Dini展开、Legendre展开）。给出了不同类型（数学或物理）问题的具体求解程序，用于分析二维外部流动、轴对称热流和流体流动、椭圆内的二维自然对流、自由表面的二维自然对流以及所获得的热场或流场。
A newly developed spectral finite difference scheme ( Fourier expansion, Dini expansion, Legendre expansion ) applicable to numerical analysis of heat and fluid flows is reviewed. Concrete solution procedures applied to different ( mathematical or physical ) types of problems are given for analyses corresponding to two-dimensional external flows, axisymmetric heat and fluid flows, two-dimensional natural convection in an elliptic enclosure, two-dimensional natural convection with a free surface, supplemented with obtained thermal or flow fields.
