摆钟时差和摆长调节量的计算

Time Differences of a Pendulum Clock and the Calculation of Regulative Amount of Pendulum Length

由天文摆钟产生计时误差的启发，提出一种新的材料线膨胀系数测量方法：直接测量单摆振动周期的微小变化量，再通过公式间接换算出该摆杆材料的线膨胀系数。

A new method that the minute change of vibration period of a single pendulum is measured firstly , then the CTE of the pendulum material is calculated by indirect conversion of formula , is put forward with the elicitation of the error of the astronomical pendulum clock .
