建立高的测量(占見)标,所用材料一般都是圆杉木,规格很粗。在高空作业中,因木料笨重搬动困难,而且费时很多,操作也不安全。利用地面排架法,减去了大部分的高空作业,使工作达到既好又快又安全。此方法经过实地试验,证明是一种先进的方法。兹介绍如下: The establishment of high measurement (accounting) standard, the materials used are generally round fir, specifications are thick. In aerial work, due to bulky timber moving difficult, but also time-consuming, unsafe operation. Using the ground-laying method, most of the overhead work is subtracted to make the work both good and fast and safe. This method has been field tested to prove to be an advanced method. Here is the introduction:
