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。

提出了一种新的基于轮廓特征的图像配准算法，首先提取图像轮廓并计算每个轮廓点的法向角，然后对轮廓点法向角进行直方图统计，通过对两幅图像的轮廓点法向角直方图进行圆周相关计算便可快速估计出两幅图像所存在的旋转角度。

Results the safe angle range for needling yamen (gv 15) were: 16.27±7.68～29.46±7.23 degrees for males and 18.46±4.81—33.61±7.83 degrees for females; the danger angle of upward oblique insertion was negatively correlated with the extension of bowing and raising the head, that is, the larger the angle of backward raising the head, the smaller the range of danger angle of needling into the great occipited foramen.

The second half inspects SciTech from the four angles of the wholeness of the system of human nature: from the angle of self, as the production of making use of objects by self, SciTech can be in favor of self or dissever self, which, the author thinks, is little helpful to the consolidation and transcendence of self; from the angle of individuality, for its aim is to eliminate individuality and to pursue commonness, there is distinct conflict between SciTech and individuality; from the angle of valueness, only have been the means of affirming and realizing the value of human nature and the purpose of personality, can SciTech have internal legitimacy; from the angle of sublimatity, human's right and rational needs make SciTech impel development of human nature healthfully, lust which is the distortion of needs make the trap, and technologizing the human nature will never be the way and aim of sublimating human nature.

下部分从人性系统整体性的四个角度考察；从自我看，科技作为自我"假于外物"的产物而推动或肢解自我，对自我的整合和提升少有实质性作用；从个性看，它是销匿个性而寻求共性的结果，与个性之间矛盾突出；从价值性看，它只有成为确证和实现人性价值和人格目标的手段，才具有内在合法性；从提升性看，人的正当合理的需要使科技推动人性健康发展，欲望对需要的扭曲造成陷阱，使人性技术化不是人性提升的途径和目标。

With the increase in tempo, the angle of hands away hail no significant change, but in 4 tempo for 3 athletes, their angle of entrance always greater than their angle of run, and their left angle of hands always were greater than right, it means that their left extent of hands away were longer than their right.

Although translator has turned from being a crystal ball by which the original culture can unrestrainedly penetrate to another crystal ball by which the target culture can freely traverse, the translator's personal embodiment, in the process of cognitive act, are still absent in translation studies. Translators are still subjects without body or simply disembodied subjects.
