一、背景物理天平是我们学习质量等知识必不可少的实验工具。在使用物理天平测量物体质量时,调节底座水平是第一步,也是非常重要的一步。底座水平调得如何,关系到实验结果的准确程度。底座水平调得平,就能减少实验误差;底座水平调得不平,实验测量结果不准,造成实验误差大。现在物理天平普遍使用的调 First, the background of the physical balance is essential for our learning quality knowledge of experimental tools. When using a physical balance to measure the mass of an object, adjusting the level of the base is the first and most important step. Base level adjustment, related to the accuracy of the experimental results. Adjust the level of the base level, you can reduce the experimental error; base level uneven, the experimental measurement results are not allowed, resulting in large experimental error. Now commonly used physical balance adjustment
