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.

结果：得出哑门穴安全针刺角度，男性为16.27±7.68～29.46±7.32度，女性18.46±4.81～33.61±7.83度。且向上斜刺的危险角度范围与头颅俯仰程度呈负相关，即头颅后仰角度越大，刺入枕骨大孔的危险角度范围越小。

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.

转桨角的变化幅度不大，但在四种桨频下，3名运动员的入水角都大于出水角。3名运动员的左转桨角比右转桨角大，意味着3名运动员左手桨叶的划幅比右桨大。

The flume experiments of equilibrium concentration in water and slurry have been done to determine the function between the kinetic friction angle and internal friction angle. The equilibrium concentration of debris flow calculated by the function between the kinetic friction angle and internal friction angle is quite close the equilibrium concentration data of debris flow in field.
