高强度的

To ensure close adhibition of connecting board, screwing should start from center to outside, that is, screwing from enlarged center to skirting area. To avoid coating's influence on tensile force, screwing work should be finished on one day. And to decrease prestress' difference of high-tension bolt, bolt screwing runs in two steps: primary screwing and final screwing. For large-scale joint with great amount of bolts demands a second screwing.

为使被连接板叠密贴紧，应从螺栓群中央顺序向外施拧，即从节点中刚变大的中央按顺序向下受约束的边缘施拧，为防止高强度螺栓连接副的表面处理涂层发生变化影响拉力，应在当天终拧完毕，为减少先拧后拧的高强度螺栓预拉力的差别，其拧紧必须分为初拧和终拧两步进行，对于大型节点，螺栓数量较多，则需要增加一道复拧工序。

In this paper, based on the experimental studies, the effects of the ARC-3 glass fiber for the improvement of the flexural tensile and the unconfined compressive of the concrete are analysed. Further statistical relations between flexural tensile strength, volume ratio of fiber and curing time, and a mathmatical model of the flexural tensile is presented. Finally, the optimum fiber volume ratio in the concrete is presented. In this paper, a mathematical model of the volation between the flexural ten...

通过采用形变热处理工艺和微合金化，在保证高韧性和优异的焊接性能的条件下，具有铁素体珠光体组织的低碳低合金高强度钢的屈服强度可以达到500～550MPa的极限水平。

The influence of recessing in adh es ive layer with high elastic modulus on the peak stress of joint is not evident so that it would improve the actual strength of joint markedly based on the load bearing ability not being affected evidenly . On the other hand , the recessing in the joint with low elastic modulus adh es ive caus es the peak stress es increase evidently that may decrease the nominal and actual strength of the joint markedly .

对胶层和被粘物中应力分布的数值分析结果表明：胶层中的间隙对接头端部的应力分布无明显影响，但对间隙附近的应力峰值影响较大；随着胶粘剂弹性模量的增大，间隙附近的应力峰值有所降低；对于高弹性模量胶粘剂接头，胶层中的间隙对接头的应力峰值无明显影响，在不降低接头名义强度的同时可使得接头的实际强度显著提高；而对于低弹性模量胶粘剂接头，间隙使得接头上的应力峰值明显上升，可能导致接头的名义强度和实际强度显著降低。

Based on these problems, this article provides a new solution of applying the boriding ——heat treatment of compound technology of austempering, it makes the face of the mold have the characteristics of high rigidity, strong wear proof and good tenacity, thus makes the li.
