在研究刚体转动中合外力矩与刚体转动角加速度的关系时,对于确定的转动系统,转动惯量Ⅰ一定,有M-Mμ=Ⅰβ,即M=Mμ+Ⅰβ。以往的实验中均把Mμ看作定值。但实际中Mμ是否恒定呢?怎样修正Mμ造成的误差,这就是本实验研究的目的。 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
