水平仪和自准直仪是一种测量小角度的常用量具,它们的用途十分广泛,但这两种仪器的使用特点却往往被人忽略。现简要介绍其测量原理,并分析测量的可靠性及使用的局限性。 使用水平仪测量时,是以自然水平面作为测量基准,根据气泡向高处移动的原理和气泡移动的格数来确定倾斜角度
Level and self-collimator is a commonly used measurement of small angle measurement, their use is very wide, but the use of these two instruments are often overlooked. Now briefly introduce its measurement principle, and analyze the reliability of the measurement and the use of limitations. When using the spirit level measurement, the natural horizontal plane is used as the measurement standard, and the inclination angle is determined according to the principle that the bubble moves to the upper position and the cell number of the bubble movement
