摘要
依据力平衡法原理,重新构思、设计了测量大气压强的实验方案及装置,力学传感器的使用,提高了大气压强测量中的关键物理量的测量精度;采用最小二乘法,实现了大气压强的巧妙测量.
Based on the force balance principle ,the experimental scheme and apparatus were rede-signed to measure the atmospheric pressure .By using mechanical sensor and least square method ,the atmospheric pressure had been measured ingeniously ,and the measurement accuracies of atmospheric pressure and the relevant key physical quantities were improved .
