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。

与chain reaction相关的网络解释 [注：此内容来源于网络，仅供参考]

chain reaction：连锁反应

59 所谓的"临界质量"(Critical Mass)和"连锁反应"(Chain Reaction)都是化学名词,是指原子弹如果达到一定的数量时,其原子分裂所释放出的热能,就足以使反应持续下去,最后导致爆炸.

chain reaction：链式反应

与所有的天然铀矿一样,该矿石含有3种铀同位素--换句话说,其中的铀元素以3种不同的形态存在,它们的原子量各不相同:含量最丰富的是铀238;最稀少的是铀234;而人们垂涎三尺,能够维持核链式反应(chain reaction)的同位素,则是铀235.

chain reaction：链锁反应

核分裂之过程可分成数个阶段,首先中子撞击重原子核;中子被吸收而形成複核(compoundnucleus);此複核并不稳定,而继续分裂成两个或以上之原子核,同时并放射出数个中子;这些中子又被其他原子核所吸收,如若具有足够之原子则可能发展形成链锁反应(chain reaction),此链锁反应即构成

chain reaction：链反应

+ 通过活性粒子(自由基或原子)使一系列反应相继连续发生,像链条一样自动发展下去,这类反应称之为[[链反应]] (chain reaction). 所有的链反应,都是由[[链的引发]](chain inition)、[[链的传递]](chain propagation)和[[链的中止]](chain termination)三个基本步骤组成的.

nuclear chain reaction：核链反应

就在这一年,恩里科.费米(Enrico Fermi)和同事们一道,用实验证实核链反应(nuclear chain reaction)是完全可控的. 费米他们当年的科学研究目的本来是为了制造核武器,且最终在日本广岛实现了这一目标. 二战时期,美国某军事委员会还负责对原子能的其他潜在用途进行研究.
