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。

proper motion：自行

事实上,恒星在正常情况下,它们的颜色与亮度在很长的时间尺度内不会有变化(只有变星以及新星和超新星爆发时才例外);恒星在天空中的相对位置,虽然存在着规律性的缓慢移动--即恒星的"自行"(proper motion)但古代中国人并未发现这一移动;
