数字式计算机如何在地形图上识别最小抵抗线位置

DIGTAL COMPUTERS'IDENTIFIGATION OF THE BURDEN POSITION ON A MAP

为将电算技术应用于露天药室爆破设计,我们进行了一些工作。在《电子计算机在露天药室爆破设计中的应用》一文中,我们就取得的初步成果作了简要介绍。并且指出,由于爆破类型的多种多样,难以用统一的电算程序来解决,因而主要着眼于一些功能单一的子程序的编写,而后,按具体情况,用适当的主程序将某些子程序组合起来。本文就各种类型露天药室爆破都要使用的最基本的子程序——子3000作具体介绍。

Working outthe direction of the burden distance on the basis of the topographical map and the charge centers is one of the fundamental jobs in designing large-scale surface coyote blast. This paper shows in detail how you could give your digital computer this function. The paper makes a particular exposition of the two important standards of judgment—"the N-crossing Criterion" and "Seven-point Criterion" and, besides, provides a detailed logic flow chart of the program
