Based on varying process of generator terminal parameters after excitation fault, shortages of excitation protective principle of static stability boundary and asynchronous impedance boundary are analyzed. It proposed that excitation fault research relates to large-disturbance stability. Because dynamic power-angle character of generator after excitation fault is non-sinusoidal, there are differences between dynamic power-angle character and static state power-angle character. So it isn't ideal to protective operation result based on small-disturbance stability and static stability boundary criterion. At the same time, it proposed that asynchronous boundary impedance criterion is a constant reactive power circle moving adown j Xd′. It can ensure complete loss-of-excitation generator measuring impedance enter into the circle, but can't ensure the other condition measuring impedance including impossible losing synchronism enter. So loss-of-excitation protection would be maloperation when system voltage drops short and recovers or generator rejects load.③Based on stability principle, it puts forward setting conditions and calculation method of generator loss-of-excitation protection by direct measuring power-angle.

以励磁故障后发电机端的相关参数的变化为基础，通过对以静稳定边界和异步阻抗边界作判据的两类三种现行励磁保护在原理上存在的缺陷分析，发现：励磁故障是一个大干扰稳定性问题，励磁故障后的发电机的动态功角特性与静态功角特性有很大的差异，已远非正弦曲线，因此基于小干扰稳定性原理、以静稳定边界作判据的保护必然动作不理想；异步边界阻抗判据是一个下移j Xd′的等无功阻抗圆，它可以保证完全失磁后的发电机测量阻抗能进入该阻抗圆，但不能保证完全失磁之外的其它状态不会进入该阻抗圆，因此在系统电压短时下降或发电机突然甩负荷等情况下可能启动该保护使之误动。

The results were as follows.(1) In the backward handspring, the trajectory of CM and horizontal velocity of CM in junior-high and college gymnasts were lower and higher than those of senior-high gymnast, so the vertical velocity is better when they perform tucked backward somersault. College gymnast has higher vertical velocity than junior-high and senior-high gymnasts in take-off moment of backward handspring phase.(2) Senior-high and college gymnasts have more elbow and shoulder angle in take-off moment of backward handspring and tucked backward somersault phase. Therefore, angle of both arm is bigger for performing in hand push away phase in the backward handspring, and increased the reaction force with body in the tucked backward handspring.(3) College gymnast has large knee flexions in hand support and push away moment in the backward handspring, it would increase rotation radius and better moments of inertia in the backward handspring.

The effect of tribology factors on bearing vibration is studied experimentally. AR model and WPT are used to processing the normal arid abnormal signals. The results are as follows:1. The vibration of ball bearings is caused by the tribology action of contact pairs of ball and ring races and has the essential of tribo-dynamics. Any factors affecting the tribology characteristics of contact pairs will affect vibration and noise of bearings consequently.2. Vibration characteristics of bearing keep almostly unchanged with the increasing of axial load expecting the increasing of nature frequencies. When radial load increasing with axial load unchanged, nature frequencies keep unchanged but some new vibration peaks appears in the spectrum.3. Vibration amplitudes are damped and nature frequency are enhanced with sufficient lubrication. Vibration and noise of bearings increase obviously and roar can happen and the contact surfaces scratch slightly under insufficient and unclean lubrication state. Bearing will be disabled in a few minutes without any lubrication.4. Bearing vibration is unstable under low speed. With the speed increasing, the vibration become stable and natural frequencies increase slightly but the amplitudes increase apparently.5. Bearing vibration can be excited only by some harmonics ofwaviness without lubrication and by all harmonics with lubrication based on the theoretical analysis.6. The nature frequencies of ball bearings decrease with the increasing sizes. When international clearance increasing, nature frequencies decrease in radial and increase in axial and angular and the amplitudes increase in radial and decrease in axial and angular. When the number of balls increasing, nature frequencies increase and amplitudes decrease. When the pitch diameter increasing, axial nature frequency increase and others nearly keep no change. When outer race groove curvature radius increasing, nature frequencies increase in radial and decrease in axial and angular and amplitudes keep no change in radial and increase in axial and angular. When inner race groove curvature radius increasing, nature frequencies decrease and amplitudes increase.7. The distortion in amplitude and frequency components of bearing vibration signals picked up by the present probe measurement method is founded and right conclusions cannot be achieved by the signals. When accelerometer is rigidly screwed with steel stud onto a flat outer surface of a ball bearing, vibration signal can be got without distortion and the reliability of research on bearing vibration is assured.8. AR model is suitable for large samples of bearing vibration signals, square root of length of samples can be used as the upper limitation of order determination and the FPE order selection criterion is effective. Many advantages of AR spectrum are founded over the classical based on FFT.9. Time-Frequency analysis is necessary for abnormal noise of ball bearings. WPT overcomes the principle shortcomings of STFT and proved to be a best tool to process the abnormal signals.

本文首先详细介绍了黑白棋的游戏规则，和一些基本的战术，然后将这些战术编写成代码存储在计算机中，使计算机在对弈过程中，可以灵活的运用这些战术。该程序主要运用的战术有削弱对手行动力战术、四角优先战术、最大贪吃战术。在游戏开局和中局时，程序采用削弱对手行动力战术，即尽量减少对手能够落子的位置；在游戏终局时则采用最大贪吃战术，即尽可能多的吃掉对手的棋子；而四角优先战术则是贯穿游戏的始终，棋盘的四角为稳定角，不会被对手吃掉，所以这里是兵家的必争之地，在阻止对手进角的同时，自己却又要努力的进角。

Fill a tulip-shaped glass with red wine to one third of a full glass (5cm from the foot of the bottom).Observe the wine. Lean 45 degrees to check its color against a white background. Fine dry red wine looks clear and glossy. By observing the color and tone of the wine, you coukd make good judgment about its maturity. Usually the deeper in yellow tone it looks, the more aged the wine is; the paler in color or deeper in purple tone it looks, the less aged the wine is.Smell the wine. Gently shake the glass for better contact between wine and air until the aroma of the wine evaporates enough. Reach your nose into the glass, smell gently and quickly. Fine red wine is rich in aroma, dense and subtle, with both the aroma from grape and the matching oak fragrance.Taste the wine. Take a deep sip, simultaneously draw in the air over the wine, whirl the wine inside every part of your mouth, fully appreciate its flavor before swallowing. Sense the aftertaste and make a good judgment of its potential quality.
