It comprises an in-put shaft hinged to its yoke through one axis, and an out-put shaft also hinged to its yoke through another axis, and these two yokes (13) were combined together by only one axis position, perpendicular to that two yoke axes like a cross, so that this combined axis will bend just like the angle bisector of that two shafts to maintain its constant velocity by a few methods, firstly, by using a section of gear teeth mesh at both ends of the shafts' teeth were so polished so that it can turn longitudinally as usual gear, and also sideways, to provide a larger solid angle of turning from ordinary 45 degrees into 60 or even more.

它包括输入轴，其通过一根轴铰链连接于叉形支架，和输出轴，其通过另一根轴也铰链连接于其叉形支架。并且这两个叉形支架(13)只需用一根相对垂直铰链轴相连而组合在一起，使得这种组合的轴总能形成这两个轴的角平分线，以通过少数几种方法保持其恒速，首先，通过用啮合在轴的两端的一段齿轮齿抛光为以能够像普通齿轮一样纵向转动，并且还能够侧向转动，以提供较大的转向立体角，从通常的45度变成60度或更大。

The cloned Buchnera groEL genes of Schizaphis graminum and Rhopalosiphum maize were ligated into pBV221,pET30a and pTrcHisA expression vector for construction of pBVRM,pBVSG, pETRM,pETSGPR,pTrcRM and pTrcSG. They were transformated into E. coli BL21(DE3),DH5a and JM109 for studying their expression.

Observations on the dichotomous leaf venation of Circaeaster agrestis found no intermediate forms of the fusion of vascular bundles between the two completely fused commis-sural veins of anastomoses and the two separate approximate veins, but found different degrees of the vestige of commissural veins .

在星叶草叶二叉分枝脉序中，网结脉中2条完全汇合叶脉与靠近脉中完全分离叶脉间未发现任何形式的维管束汇合的中间类型，相反观察到了网结脉中不同程度的连接脉退化的痕迹，因此网结脉不可能由靠近脉形成；盲脉的出现与齿的退化、网结脉中连接脉的间断及非网结脉由分枝处间断等相关；上述事实表明星叶草叶的二叉分枝脉序应为一减化性状。
