【摘要】 本实验是用转动惯量实验仪和电脑计时、计速仪来测量数据 ,用转动定律和平行移动轴定理推导新的线性方程 ,再用方程中的自变量和变量关系进行画图 ,成一条斜直线 ,从而间接地验证了转动定律和平行移轴定理成立 ,计算出转动惯量的大小。这种测量方法可达到国内较高的测量水平。与原来的测量方法相比 ,可消除较大部分系统误差和偶然误差 ,使数据接近真值 ,测量方便 ,重复性好 ,节省时间 ,效率高 ,可实现设备资源共享 ,可以解决实际问题。更多还原

【Abstract】 The data of text is surveyed by turning’s inertia instrument and count time and velocity instrument.This way can make the test have much less tolerance than old the way.It makes the data is more close to the real situation.The test becomes convenient and efficient.It can make new linear dualism equation with twhing law and paralle axis theoyem Then make a picture what is a line by the theorem and it uerify turhing lnoand parallelaxis theoremc.更多还原
