The paper induces and analyzes research method of the tooth, including Method line of the tooth theory,Envlopment theory, Camus theory, Circling cluster theory and so on.Based on the past theories,the new measure to deduce the chain wheel tooth equation of roller chain at high speed,Circling cluster and envlopment theory,is proposed by analyzing basic concept of equidistant curve and Willis theory.Following the presentation of drawing lessons from traditional roller chainof the change of stanza line distance. A new type of roller chain at high speed is given in the paper.The paper studies deeply structural characteristics, the change of stanza line distance,separation between plank and bore and so on.According to design requst of roller chain at high speed and the study ofH_y--V_0 tooth chain,the impossibility that Quasi-conjugage engagement theory isrealized by the engagement of roller chain at high speed from the aspect of theory is decribed.

作者综述了高速滚子链国内外研究现状，并进行了以下研究工作：归纳分析了齿形法线法理论、包络法理论、卡姆士定理、圆族法理论等齿形研究方法，在此基础上，结合齿形啮合基本定律，分析了等距曲线的基本概念，提出了一种推导高速滚子链链轮齿廓方程的新方法—圆族包络法；在借鉴普通变节距滚子链的基础上，本文提出了一种新型的高速滚子链链条，深入研究了高速滚子链链条结构特性及其变节距、板孔中心分离等特性。

Each non-isotropic engagement member (56) has a stem portion (58), and a securement element (60) which is non-isotropically disposed at a distal end region of its corresponding stem portion (58) to provide a non-isotropic engagement opening.

每个非各向同性接合件(56)具有杆部分(58)，和在其相应的杆部分(58)的远端部设置的固定元件(60)，以提供非各向同性接合开口。

The distribution of gear's contact stress, root stress, and contact engagement line in the engagement situation of gear pairs, were obtained on the base of explicit integration method. 3. Adopting the method of system matrix, the torsional vibration differential equation of general shafting was gained. The simple harmonic forms of excitation torque under the normal combustion or piston flameout of in-line engine and v-type engine were analysed. The decoupled algorithm of free vibration and forced vibration and the solution to the vibration damper's energy of resistance and the off-resonance calculation were studied. The sensitivity formulations of the natural frequency and vibration mode to physical parameters of system were derived by solving the eigenvalue problem. These sensitivity formulations provided the theoretical base for the dynamic modification of structure.

运用系统矩阵法建立了轴系的扭振微分方程，并对直列和V型发动机在正常发火和气缸熄火工况下的激振力矩进行了详细的简谐分析；基于精确方法推导了自由振动和强迫振动的解耦算法，给出了能量法计算中的减振器阻尼功求解和非共振计算方法；并研究了曲轴系扭振非线性分析中的变惯量问题，得到了单缸转动惯量的精确求解公式以及变惯量和固有频率的关系式；最后，从特征方程和振型正交性出发，推导了固有频率和振型对轴系转动惯量和刚度等物理参数的灵敏度，为扭振系统的结构动力学修改提供了理论基础。

Moissanite and platinum engagement rings are other types of diamond alternative engagement rings that many couples are now choosing.

Most of hob design for non-involute gears are nowadays taken by approximation method.For example,the normal sectional profile of hob worm therad is usually regarded approximately as its basic rack profile.Recently, some new methods have been developed in this respect but, perhaps, they appear overelaborate since the principle of spacing engagement is based on. For this reason , the paper offers a new design procedure for hob worm based on the planar engagement principle with the intention of simplific...

本文应用平面啮合原理精确设计各种非渐开线齿轮滚刀的基本蜗杆，提出并应用啮合线的投影原理从工件齿轮端截面的啮合线直接求得刀具蜗杆的端面齿形，而不必求出媒介齿条的齿形，方法很简单，还从啮合线的投影原理简明而形象地证明了一对螺旋齿轮直接啮合过程的啮合线是一条垂直于齿向的平面曲线。

But if the engagement only has moral obligation, the moral observer will only be fetters, and those who violate the engagement will be connived.

但是，如果婚约仅有道德约束性而不具有任何法律效力，那么，婚约就很有可能只是约束了有道德的守约人，对道德低下的人任意毁约反而是一种纵容。
