Cold finished products include wire, rod, and bar applications that have been used in the automotive and commercial industries.

冷加工产品包括线材、杆材和棒材应用，这些已用于汽车工业和商业中。

On the condition that the axes of two chain wheels are in the same horizontal plane, the paper considers that the mesh drive of chain and chain wheel is equal to single small angle movement of four-rod mechanism every time on tight side.

在两链轮的回转中心同处一水平面的条件下，视紧边每一时刻链条与链轮的啮合传动为四杆机构作小转角的单向运动，建立起相应的链条速度模型，并据此分析了影响链传动中链条速度波动的因素，得到了一些有益的结

At the same time, the finite staff element method is used to analyze the influence of beam rigidity; and the two new methods proposed are used to analyze the influence of connect way between piles and beam; and the conclusion is obtained that the rigidity ratio between beam and piles being 0.48 is appropriate; the continuative increase of the rigidity ratio is not significant; the worst condition is that connecting way between piles and beam is hinged; the best condition is that connecting way between piles and beam is rigid. Whether is single-row pile or are double-row piles, when the front of single-row pile or the front of the front-row pile(in the double-row piles) needed excavation, it is supposed to that ought to be carefulness to excavate, because it is that the engineering cost increased greatly.

同时，用有限杆单元法，对双排桩的连梁刚度和用文中提出的方法以桩梁连接方式进行了试验和理论分析得出如下结论：在满足不相互影响排桩间距的情况下，桩顶连梁与桩的刚度比不小于0.48是合适的，此时再增加连梁刚度无意义；桩梁连接为铰结时双排桩受力变形性质最差，刚结时受力变形性质最好；不论是单排桩还是双排桩，桩前和前排桩桩前土体需要开挖时应慎重，因为这种开挖对支护结构影响很大，造价增加很多；双排桩省钱，而且抵抗变形的能力强，值得在工程中研究和广泛应用

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
