摘要 将零阶Whitney延拓推广到非各向同性的欧氏空间中(这里距离的定义与原来的欧氏空间不同,其距离定义为抛物距离)。这样在实际计算中需要求解正则性较差的区域中的抛物型偏微分方程时,可以先对区域进行适当扩张,再进行数值计算。 Zero order Whitney extended to the continuation of the isotropic in Euclidean space, here the distance with the original tanee. It is calculated in first, region appropriately definition is different, its Euclidean space distance defined as parabolic disneed in poorer areas of properties of paraboli expanded, then numerical calculation is carried c partial differential equation, out.
