普通測量与中学数学有密切的联系,在中学数学教学中可以适当地讲授測量的基本知識;尤其是在平面几何及平面三角的教学中,可以系統地讲授小平板測量的基本知識。但是在小平板測量中有些問題是值得研究的,这些問題沒有很好地用数學推导其道理;今将个人的看法写出来,希望大家給以指正。一、平板仪的定水平平板仪定水平的方法一般是这样:先将三脚架支成鼎足形,把平板定稳,在平板上使水准器与二脚的联綫平行,轉动基座螺絲使汽泡居中(如图1——平板平视图);移动水准器使与他二脚联綫平行,轉动基座螺絲使汽泡居中(如图2);再移动水准器与原来二脚联
Ordinary measurement is closely related to middle school mathematics, and the basic knowledge of measurement can be properly taught in middle school mathematics teaching; especially in the teaching of plane geometry and plane triangle, the basic knowledge of small plate measurement can be systematically taught. However, some problems in small flat-panel measurement are worthy of study. These problems do not use mathematical reasoning to derive their reasoning. Now we write personal opinions and hope that everyone will give us corrections. First, the flat-panel leveling method is generally the level of flat-panel instrument is: first tripod into a tripod-foot, the plate is stable, in the flat plate so that the level of the two feet in parallel with the rotation of the base screw Bubble center (Figure 1 - flat view); mobile level parallel to his two feet line, rotate the base screw to bubble center (Figure 2); then move the leveler with the original two feet
