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。

Herons came, with a great bold noise as of opening doors and shutters, out of the boughs of a plantation which they frequented at the side of the mead; or, if already on the spot, hardily maintained their standing in the water as the pair walked by, watching them by moving their heads round in a slow, horizontal, passionless wheel, like the turn of puppets by clockwork.

In any type of let-off motion in which the warp sheet passes over a back roller, the tension in the horizontal part of the warp sheet will be greater than that in the warp sheet between the back roller and the beam, because if the back roller rotates, force is required to overcome friction in its bearings, and if the back roller does not rotate, there will be friction at its surface.

任何类型的送经机构，经纱片均绕过后梁，处于水平位置的经纱的张力要比后梁与织轴之间的经纱张力大。这是因为，如果后梁转动，就需要力来克服轴承处的摩擦；如果后梁不转动，在后梁表面会有摩擦。
