【摘要】 提出一个新的下丘脑垂体性腺轴（男）脉冲分泌的动力学模型，此模型既考虑到了激素的各种复杂的相互作用，又考虑到了睾酮实际处于两种不同的状态（游离态和结合态）中．此模型推出的结果既与许多实验结果相符，也可以解释激素的脉冲分泌现象更多还原

【Abstract】 Using general definition of moment of inertia of the rigid body and a serious deduction, It obtained“the theorem of moment of inertia" of the rigid body about arbitarary axis. Then using the result obtained in this paper,it also gave theorem of moment of inertia about parallel and vertical axis respectively. Examples showed that "the Theorem" is concise and easy to use.更多还原
