Both cases are acompanied by the light-emission from the transition from higher excited-state to lower excited-state, and the total superfluous band energy of nuclear system is released by means of excited element, and an energy level appears in the ground-state band, which signifies a quantum phase transition.

基于微观IBM理论，提出转动诱导出玻色子量子相变的一种可能途径：一旦原子核在受到高能激发或作快速旋转时，假如外界提供的能量足以使玻色子完成拆对顺排，则核处于集体相与单粒子态的共存相，其特征是出现较密集的能谱；假如能量不足以完成拆对或顺排，可能发生两种情况之一，当核旋转达到某个临界转动频率ω c时，或者一个高角动量的玻色子脱离"集体"而"游离"出来，或者发生一个高角动量的玻色子转变为一个低角动量的玻色子，核仍旧处于集体相；均会伴随出现光辐射，产生基态带的一条能级——相变信号。

Firstly, the natural frequencies and normal mode shapes of the fluid-conveying pipe with zero fluid velocity (i.e. U=0) were determined with the transfer matrix method. Next, these natural frequencies and normal mode shapes were used to derive the equation of motion for the fluid-conveying pipe with fluid velocity U.neq.0 by using the expansion theorem. Finally, the free and forced vibration responses of the pipe with flowing fluid were obtained by means of the Jacobi method and the Newmark direct integration method.

首先吾人使用转移矩阵法来求取一流速等於零(即U=0)、跨距数为N之流体输送管的自然频率及其所对应之正规化振态，然后利用振态重叠法原理来推导流速不等於零(即U.neq.0)时，整个流体输送管在外力作用下的运动方程式，最后再以Jacobi法及Newmark直接积分法来计算该水平流体输送管的自然频率及强迫振动反应。

It is deemed here that the legitimacy of power under the peculiar conditions of ancient societies was destined by the other world outside of human beings', such as religion, theology, etc. In ancient societies, the power and governance were justified by means of God's will, divine regulations, exceptional human power and exterior transcendentalism.

本文认为，在古代社会特有的历史条件下，古代社会中权力的合法性由宗教、神学等外在于人的彼岸世界所支撑，古代社会的权力，往往要借助神的意志或是神法规则，借助超人的力量和外在的先验秩序来赋予自身统治的合法性。

As pointed out in my doctoral thesis, we are allowed to abstract a limited form of this from our experience with finite collections, since we know that, should we doubt the conclusion derived by means of this, the conclusions can always be checked out by finite sequence of trials! But we have no such experienced assurance of the safety of this procedure with infinite collections!

正如我在博士论文里指出的，我们可以从对有限集合的体验中抽取有限形式的逻辑规则，因为假定我们对运用这些规则推导出来的结论持怀疑态度，那么我们可以用有限数量的实验步骤对这些结论加以检验！
