摘要
提出了一种测量重力加速度的新方法,结合CCD杨氏模量实验仪给出了重力加速度和杨氏模量的物理关系式,从测量结果可知,所测重力加速度与标准值相比其相对误差甚小,说明该实验方案确实可行,具有一定的应用价值。
It presents a new method for measuring the acceleration of gravity,Young＇ s modulus with CCD experimental instrument gives gravity and Young＇ s modulus of the physical relationship. From the measurement results, the measured value is compared with the standard acceleration of gravity relative error is very small, indicating that the experimental program is feasible, has a certain application value.
