摘要: 论证了作图法的几何原理------四点共圆. 介绍了四点共圆作图法在计算机辅助下的求解和构建复杂滑移线场的过程. 并以有心扇形场为例，演示了该方法的解题步骤. 通过实例计算，将该方法的求解结果与作者用数值积分法和矩阵算子法的求解结果作了比较，证明该方法计算精度高、绘图质量好.

Abstract: Abstract: Taking the centered-fan fields for example, the application of an orthogonal net of circles for construction of the complex slip-line fields are discussed. The results of this method are compared with the results of the numerical method and the matrix-operator method. The calculation shows that result of above three methods proffers a good approximation.
