摘要
本文导出了计算各种三角形条件方程式总数的通用公式,并按取简删繁的原则,用优化的形式给出了一套计算网中各类条件式数目的统一公式,改变按不同网形进行判断的现状,以期达到便于手算、机算,避免出错的效果。
The paper deduces the general formulas to reckon the total number of conditional equations in various nets of triangulation. According to the Simplilied principle, using optimal form, a set of unified formulas to reckon the number of all kinds of conditional equations is given. The existing state of judging by means of various nets is improved in order that manual calculation and computer are convenient and errors are avoided.
