常常需要测定地球表面不同地点上的重力加速度,这就需要有携带式的高精度重力仪。这样的仪器已由苏联标准化科学院自动化与电气化装置研究所研制成功。原理示意图见附图。用这台仪器通过下面的公式则可计算出重力加速度:
Often it is necessary to determine the gravitational acceleration at different locations on the Earth’s surface, which requires a portable, high-precision gravimeter. Such instruments have been developed by the Institute of Automation and Electrification of the Institute of Standardization of the Soviet Union. Schematic diagram shown in the drawings. Use this instrument to calculate the gravitational acceleration using the following formula:
