连接榫

Distribution of contact stress and contact status of dovetail joint are obtained,and the location of fretting fatigue crack predicted.

进一步应用该位置处的应力场和接触状态进行结构的寿命预测，通过燕尾榫连接结构的低周微动疲劳试验，获得了寿命预测模型中的相关参数。

Distribution of contact stress and contact status of dovetail joint are obtained, and the location of fretting fatigue crack predicted.

针对燕尾榫连接结构，采用有限元技术求解接触问题，获得结构接触应力及接触状态量的分布，并预测裂纹萌生的位置。

According to 3D analysis, it is known that shear transfer between rings are carried out by three ways. First is friction between ring joint faces; Second is dowel effect of circumferential bolts; Third is contact-hold effect of tongue-and-groove.

从三维分析可知，错缝拼装衬砌的环间剪切力传递主要通过三个途径实现，一是环缝处两个环面之间的摩擦；二是纵向连接螺栓的销栓作用；三是环缝凹凸榫的接触咬合作用。

Indeed, its massive lintels are bound to their uprights by mortise-and-tenon joints taken straight from carpentry, an eloquent indication of just how radically new this hybrid monument must have been.

事实上，它巨大的楣石就是以榫接方式与竖立的石块连接，跟现代木工如出一辙，强烈表现出这座混杂着不同特征的遗迹在那个年代新颖得有多么彻底。

Bao Luo decorative wall systems are energy-saving polyurethane directly on the 0.5 mm thick aluminum sheet on the foam, using mortise slot connections, hanging decorative construction insulation system.

罗宝外墙节能装饰系统是聚氨酯直接在0.5毫米厚铝板上发泡，采用榫槽连接，干挂施工的保温装饰系统。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
