As a result of the heightening of mechanical operation speed and the application of new materials and new structures, the nonlinear dynamic behavior in rotating machines is becoming increasingly outstanding and important. nonlinear dynamic phenomena in rotating machines cant be described, explained and predicted by rotordynamics based on linear system theory. along with the deepening and permeating of nonlinear scientific research, the nonlinear vibration of rotor systems has become an attractive field in recent years. from a point of view to set up the distinct corresponding relations between vibration states and failures of rotating machines, main advances in the research of rotor nonlinear vibration are summarized, and typical nonlinear dynamic phenomena and their forming mechanism are also summed up in the paper. the aim of the paper is to enrich the diagnostic knowledge base of rotating machines. 55refs
由於機械運轉速度的不斷提高和新型材料、新型結構的推廣應用，旋轉機械的非線性動力學行為日顯突出和重要.基於線性系統原理的轉子動力學理論與方法難以對實踐中出現的豐富的非線性動力學現象作出準確的描述、闡釋和預測.近年來，隨著非線性科學研究的深入和滲透，轉子系統非線性振動已成為應用力學和機械工程領域的研究熱點之一.從有利於建立旋轉機械振動狀態集與故障集之間的映射關系出發，綜述了近年來轉子系統非線性振動研究的主要進展，總結了轉子系統中出現的典型非線性動力現象及其產生機理，目的在於豐富旋轉機械故障診斷知識庫.參55 -
Provides a virtual - trackball alternative for rotating objects. only works in fullscreen mode in main view
在操作物件旋轉時提供一組軌跡球供操作，僅能工作于全螢幕的模式下的主視窗。 -
For the transition induced by the asymmetric perturbations is double - direction, the particle number in the core state is always less half of the total particle number. so, from the point of view of average over time, it is a coexisting state of rotating and without rotating that is formed. this state which is in the josephson tunneling regime of the macroscopic quantum tunneling is a quantum self - trapping state
由於不對稱的微擾引起的躍遷是雙向的，使得核心態上的粒子數總是少於總粒子數的一半，因此從時間平均的角度看，形成的是旋轉的和不旋轉的態共存的狀態，而且處于宏觀量子隧穿的約瑟夫森隧穿區域中，是量子自束縛狀態。 -
In this paper, complex constraints theory and rotating mode substructure are used in view of the character of cyclically symmetric structure. only a cyclically sector is selected as the calculating region instead of the whole structure, through which the static, dynamic and transient characterestics of the whole structure are obtained successfully
