The simulation study mainly concentrates on the following aspects: the relations of attack angle versus caudal fin motion, the phase difference of heaving and pitching motion of caudal fin motion, swimming velocity and body motion, body wave length and body motion, heaving amplitude and body motion, Strouhal Number and body motion.

具体研究内容包括：最大击水角度对尾鳍运动的影响；尾鳍摆动—平动运动相位差对尾鳍运动的影响；游动速度对鱼体运动的影响；鱼体波波长对鱼体运动的影响；尾鳍后缘最大摆幅对鱼体运动的影响；斯德鲁哈尔数对鱼体运动的影响。

Based on description method of damping motion in mechanical vibration, variables movement of generator are divided into two basic motion models: damping oscillation and critical damping motion. Detail methods of extracting damping parameters from simulation data is introduced to establish variable motion models. An approximate method is put forward to simulate low-frequency signal and generator response characteristic, from which motion models and damping parameters of main variables are obtained. The influences of oscillation amplitude, frequency and initial operating point of power system to the motion damping parameters are analyzed.

借鉴机械振动中阻尼运动的描述方法，将低频振荡下发电机主要变量的运动归纳为阻尼振荡和临界阻尼两种基本运动形态；介绍了从仿真数据提取阻尼参数建立参数运动模型的方法，实现对发电机振荡特性的量化分析；提出一种系统侧低频振荡信号的近似模拟方法，并应用于发电机响应仿真，获得了主要变量的运动模型和阻尼参数；分析了系统侧振荡幅度、频率以及初始工况对发电机功角振荡的影响。

This proposal has been tested in the present study, in a second-order motion configuration, which was assumed to be irresolvable for the linear filter model. A luminance defined first-order motion and a motion-contrast defined first-order motion were used as control conditions. The results suggest that there was no significant difference between the amplitudes of the flash-lag effect in the second-order motion and in the first-order motion.

用视网膜外推机制不再有效的二阶运动刺激取代前人实验中的一阶运动刺激来研究闪现滞后现象，发现在视网膜推断机制失效的情况下，闪现滞后现象并没有减小，而是和一阶运动刺激条件下的量相当。

perpetual motion：永恒运动

永恒运动(Perpetual motion)在传统物理定律中是行不通的,但在量子(quantum)世界里,无摩擦力(frictionless)运动却是可能的. 例如,由超导线(superconducting wire)构成的一个闭锁回就能够展示永恒运动现象──尽管这只是电子在无摩擦力的导线回路中运动.

perpetual motion：《无穷动>

推荐~>(perpetual motion) 我简直怀疑我是怎么坚持把这个片子看完的. 不少媒体称其为:中国版绝望的主妇,我看了之后是挺绝望. 丑成那样了能不让人绝望吗?不知何时,能去北京住住胡同里的四合院. >(First Blood) 一套三张碟,

perpetual motion：恒动

perpendicularity 垂直度 | perpetual motion 恒动 | perpetual motion machine 永动机

peroxydisulfuric acid 过硫酸 | perpetual motion 永久运动 | perphenazine 佩吩嗪

perpetual motion machine：永动机

永动机(perpetual motion machine)也许是最能够体现人类乌托邦思想的机械设计了. 为了获得源源不断的、永恒的动力,这一在今天已经被证明为不可能实现的、违反热力学第一或第二定律的动力机械已经在数百年来吸引了无数人们为之迷狂,并投入了大量的心血.
