转动惯量测量实验是大学物理实验中综合实验项目之一,目前高校工科物理实验常用三线摆法测量刚体的转动惯量,而转动惯量测试仪目前都无测量过程周期自检报错功能,为减少学生使用过程中出错概率,对仪器增加自检功能,提高测量准确度,同时为方便记录,增加了周期记忆功能。 相似文献

本文指出,双通道计时法测量刚体转动惯量的误差比单通道测量误差小;此时,外力矩中不考虑加速度α时引入的测量偏差更是不能忽略,要对测量值进行修正. 相似文献

The influences of σ^* and Ф mesons, temperature and coupling constants of nucleons on the moment of inertia of the proto neutron star (PNS) are examined in the framework of relativistic mean field theory for the baryon octet {n, p, A, ∑^-, ∑^,∑^+,^-, ^0} system. It is found that, compared with that without considering σ^* and Ф mesons, the moment of inertia decreases. It is also found that the higher the temperature, the larger the incompressibility and symmetry energy coefficient, and the larger the moment of inertia of a PNS. The influence of temperature and coupling constants of the nucleons on the moment of inertia of a PNS is larger than that of the σ^* and Ф mesons. 相似文献

The variable moment of inertia (VMI) model proposed by Holmberg and Lipas has been shown to be a special case of the VMI model
of Mariscottiet al. The solution of Mariscotti’s model is expressed in terms of hypergeometric functions, which directly give the rotational
energies or their expansions in terms of the quantityF(F+1), whereF is the total angular momentum. The present way of looking at the VMI model also tells us how to write the general dependence
of the vibrational energy and the moment of inertia on the energyE
