电光阻力天平利用游标原理，能比较准确地读出指针的位置。上皿天平秤盘在上侧灵敏度较低。电子天平它是传感技术、模拟电子技术、数字电子技术和微处理器技术发展的综合产物，具有自动校准、自动显示、去皮重、自动数据输出、自动故障寻迹、超载保护等多种功能。电子天平通常使用电磁力传感器（见称重传感器），组成一个闭环自动调节系统，准确度高，稳定性好。当秤盘上加上被称物时，传感器的位置检测器信号发生变化，并通过放大器反馈使传感器线圈中的电流增大，该电流在恒定磁场中产生一个反馈力与所加载荷相平衡；同时，该电流在测量电阻Rm上的电压值通过滤波器、模/数转换器送入微处理器，进行数据处理，后由显示器自动显示出被称物质量数值。，牛顿并未就引力本质作出结论。牛顿在科学上的成就须由他的哲学思想和科学方法来寻根求源。牛顿的学生R.科茨曾在《原理》第2版序言中道出了其中的奥妙。古希腊、古罗马的哲学家凭着对自然现象的观察和思考（战国时期也有类似
