Through transformation of parameters, the meshing design system among Hy-Vo silent chain, sprocket and hob was built up based on the research of the pitch increment and the equivalent apothem increment of the effects on the common normal line length when the Hy-Vo silent chain was wrapped around and located on the sprocket, with the proper meshing conditions of Hy-Vo silent chain and sprocket into consideration. The design method of common normal line length was put forward that can be used when the value of the sprocket pressure angle was equal or unequal to the value of the Hy-Vo chain plate pressure angle.

在分析Hy-Vo齿形链链节围在链轮轮齿上定位时其节距增量和当量边心距增量对链轮公法线长度影响的基础上，根据Hy-Vo齿形链与链轮的正确啮合条件，通过参数变化，建立了Hy-Vo齿形链－链轮－滚刀三者之间的啮合设计体系，提出了既适用于链板齿形角等于链轮压力角情况，也适用于链板齿形角不等于链轮压力角情况的Hy-Vo齿形链链轮公法线长度的计算方法。

螺旋角是指在锥齿轮节锥表面展开图上的齿线任意一点A的切线TT与该点和节锥顶点连线之间的夹角。在齿面宽中点处的螺旋角称为中点螺旋角(图5—4)。通常不特殊说明，则螺旋角系指中点螺旋角。双曲面齿轮传动比为

The effects of nonsolventγ-butyrolactoneon the behavior of phase separation of PC casting solution were studied at different operating temperature according to the LCP correlation.It was found that the phase separation behavior of PC/NMP/γ-GBL also exhibited well agreement with the LCP correlation.Therefore,the maximum content ofγ-GBL in casting solution could be obtained according to the binodal line of the system,which provided scientific basis for the composition of casting solution.

However,when increasing x_(12) in the range of larger than 1,the change tendency of the binodal curve position is also affected by the values of x_(13) and x_(23).(3) The ternary phase diagrams of ScCO_2/acetone/CA,ScCO_2/toluene/PSt and ScCO_2/solvent/PVB systems are calculated using the thermodynamic model.

当x_(12)在小于1的范围内变化时，随着x_(12)的增大，均相区增大；然而当x_(12)的数值跨越了该分界点在大于1的范围内变化时，随着x_(12)的增大，双节线位置的改变将受到x_(13)、x_(23)具体数值的影响，从而不再沿单一方向迁移。

By means of the constructed ternary phase diagrams of these systems,it is found that the binodal curve of ScCO_2/acetone/CA system is quite close to the polymer/solvent axis.

相图研究结果表明：ScCO_2/丙酮/CA成膜体系的双节线距离聚合物/溶剂轴很近，且在聚合物浓度为25wt。

It was found that the phase separation behavior of PPESK, ie., PPESK/NMP/H_2O and PPESK/NMP/NSA, all agree with the LCP correlation. The binodal lines of the three systems were calculated according LCP correlation. Therefore, the maximum content of NSA in the casting solution can be calculated according to the binodal lines of the system, which is a scientific solution for the establishment for the composition of casting solution.

实验结果表明LCP关系可以用于描述PPESK／NMP／H_2O和PPESK／NMP／NSA三元体系在相分离时的浊点组成，并根据LCP关系外推计算三元体系的双节线，由此可得铸膜液体系中非溶剂添加剂的上限含量，为PPESK铸膜液体系组成的构建提供了可靠的科学依据。

The study on polygonal or chordal action, the associated impact between rollers and sprockets and dynamic loading in the system is carried out with different motion laws.An experimental apparatus is set up to investigate dynamic behavior of intermittent chain drive system thoroughly.

为拾取链节在运动中的振动信号，设计了一套特殊的反凸轮——滑块机构，可实现测试信号线与链节保持同步运动，从而避免了信号线与链节发生缠绕的问题。

The contents of valine and leucine of the nematode are obvious higher than that of others in different kinds of amino acid of the nematode. The analysis of irritant factors playing a important role on the production of predacious organs showed that live nematode larva or its lytic solution can cause the production of predacious organs of the strain A1, but the latter produced less than the former .The live larva of the third stage produced more predacious organs than one of the first and the second stage , so the number of predacious organs that are produced by the live larva of first and the second the stage are less than the live larva of the third stage .

刺激捕食器产生的因素在线虫体来说：活的线虫幼虫和其裂解液可以刺激捕食线虫性真菌—少孢节丛孢菌菌株产生捕食线虫性结构——捕食器；但后者刺激产生的捕食器数量较少；有活力的第三期幼虫与第一、二期幼虫相比较，可以刺激菌株产生较多的捕食器；但少孢节丛孢菌对第一、二期幼虫作用速度快；与第三期幼虫相比，第一、二期幼虫易被捕获致死。

The assay of the coarse protein , a variety of amino acid about nematode-trapping fungus — Arthrobotrys oligospora strain A1 and the third stage larva showed that the contents of the coarse protein and a variety of amino acid of larva are mostly higher than that of predacious organs containing annulus and cohesive net ,conidia and hypha in the different growth phases.
