By the use of Circling cluster and Envlopment theory and flat surface sit-mark transformation theory, the chain wheel tooth equation of roller chain at high speed to match conjugage engagement is deduced.Establishing chain speed equation of roller chain at high speed,based on the analysis of the speed curves between roller chain at high speed and common roller chain,good drive of roller chain at high speed is verificated theoretically.By a example that move distance from transverse vibration between roller chain at high speed and common roller chain is contrasted,the accuracy of those theories that the paper brings up and higher functions of roller chain at high speed is proved.Finally, Establishing conjugage engagement line equation of roller chain at high speed and analyzing the complete engagement zone, the chain wheel tooth curve equation is studied at a higher degree. At the same time,the lack's place of the research result is pointed out.

依据高速滚子链设计要求与H_y-V_0齿形链的研究，阐述了滚子链传动实现准共轭啮合理论可能性；利用圆族包络法结合平面坐标变换理论推导出了满足共轭啮合的高速滚子链的链轮齿廓曲线；建立起高速滚子链链速方程，通过对高速滚子链与普通滚子链链速曲线的对比分析，从理论上验证了高速滚子链具有良好的传动性能；最后，建立起高速滚子链共轭啮合线方程，对其整个啮合区间进行了分析，进一步研究了链轮齿廓曲线方程，确定了主要参数的设计方法的问题，并同时指出了不足之处。

In one hand, in the progress of children"s socialization, television medium, instead of family and schools, play the role of advancer in some extent. In another hand, because of television programs" different qualities, there are a lot of differences in different childrens moral, communication, studying and entertainment. The fifth part show the conclusion of this paper.

通过研究发现，电视媒介对农村留守儿童的道德状况、社会交往、学习及休闲等方面产生了双重影响：在农村留守儿童社会化的过程中，由于家庭的缺位，学校教育的补位不足，使得电视媒介在其社会化过程中充当了桥梁和伙伴的角色：然而，电视媒介内容的良莠不齐，导致农村留守儿童呈现出的道德水平落差大、社会交往能力差、学习成绩两极以及休闲活动盲目化等特征，指出电视媒介在农村留守儿童社会化过程中所起到的重要作用。
