在电气安装维修工程中,校对电缆(或成扎导线)芯线是一项大量而繁琐的工作。人们在长期工作实践中,总结和创造出许多简便有效的方法及各种校线仪器。校线的目的主要是解决一个给导线排序编号的问题,解决此类问题,运用数学思维的方法就显得比较容易。下面所要介绍的就是运用数学方法较好地解决了如何准确、快捷、简便地完成校线工作的二个实用 In the electrical installation and repair works, proofreading cables (or into the wire) core is a large and cumbersome work. People in the long-term work practice, summed up and created many simple and effective method and a variety of school instruments. The main purpose of the school line is to solve a problem of the numbering to the wire, to solve such problems, the method of using mathematical thinking is relatively easy. The following is to introduce the use of mathematical methods to better solve the problem of how to accurately, quickly and easily to complete the school line of the two practical
