摘　　要：将实验室常用的测高仪加装一个精密测角仪后,可在实验室采用两次三角高程测量方法实现建筑物的高度测量.测量时在同一个测量点短距离改变测量竖直角的望远镜位置定位,分别测量两次被测点的竖直角,可以不必直接测量水平距离而实现高度的间接测量.增加了一种高度测量方法,拓宽了物理实验教学内容.By adding a precision goniometer to the altimeter commonly used in the laboratory,two times of trigonometric leveling can be used to measure the height of a building in the laboratory.In order to measure the height indirectly without measuring the horizontal distance,we measure the vertical angle of two measured points separately by changing the position of the vertical angle of the telescope in the same measuring point.A method of height measurement is added and the content of physical experiment teaching is broadened.
