本文详细讨论了用伍氏(Wulff)赤平极射投影网制作极点等值线图的原理,并给出了相应的电算程序。用一个具体实例将所得结果与用施米特(Schmidt)作图法得到的结果进行了比较。此例说明,经改正的伍氏网作图法更精确,但占用计算时间更长,而用两种方法得到的等值线图大体上是彼此接近的。 This paper discusses in detail the principle of making polar contour maps using Wulff polar projection projection nets, and gives the corresponding computer program. A specific example was used to compare the results with those obtained using the Schmidt plot method. This example shows that the modified Wu’s network plotting method is more accurate, but takes longer to calculate, and the contour plots obtained by the two methods are generally close to each other.
