摘要通过数值模拟软件ANSYS分析对接接头的工作应力分布，找出了对接接头的几何参数对应力集中系数的影响。

When connecting rubber joint and pipe flange,the bolt pole shall extend to the pipe flange so as to prevent from crushing or pricking the coved screw thread expanding because of pressure, all bolts shall be pressured and screwed down and word congruously, If the surrounding circumstance is bad,spring washer and flat gasket shall be added to prevent bolts from loosing .

4，若使用拱形或高弧度橡胶接头时，（因螺栓六角难以穿过法兰孔），必须采用双头螺栓，并尽量减少球体端螺纹突出部分，以免球体受压膨胀时被挤伤，使橡胶接头早期损坏。

The results show that the simplified equations can be used to calculate the weld magnification factor not only for the T-butt joint but also for the butt, cruciform joints.

The author determines the fatigue property in super long life region of the cruciform joint of 16MnR base material of one ...

作者利用瑞士RUMAL电磁高频疲劳试验机测定16MnR板材十字单面焊接接头在超长寿命区间的疲劳性能，并采用标准法和Dixon-Mood法对测得的试验数据进行处理，整理出十字单面焊接接头在超长寿命区间的疲劳极限，这些结果可以为焊接结构的可靠性设计及服务寿命估计提供试验数据基础。

Butt,T-butt and cruciform weldments are typical joints in ship and ocean structures. Most of the fatigue failure can be traced to the weld toe.

对接、T型接头与十字接头是船舶与海洋结构的典型结构形式，其大部分疲劳失效是由于焊趾引起的。

The pipe couplings should maintain the normal working condition under the maximum allowable deflexion and dislocation.

柔性管接头具有随一定末端载的能力。末端负荷是指管接头槽口可承受沿钢管轴向负荷的能力。

Bonded joint was obtained by diffusion bonding at constant temperature and pressure, phase transformation superplastic diffusion bonding and diffusion bonding under pulsatile pressure. The strength of welding joint was tested and metallography of welding joint was observed.

采用恒温恒压扩散焊、相变超塑性扩散焊和脉冲加压扩散焊实现了钛合金和不锈钢的焊接，测试了焊接接头的强度，并对接头进行了金相观察。

The only alternative and referential way to predict the phase transformation temperature is to make use of the continuous cooling transformation diagrams, which are measured dilatometer curves that have not taken the effect of practical welding conditions into account.

由于焊接过程的瞬时性和焊接热影响区温度场、应力场的复杂性，该区域的组织转变往往并不完全遵守热处理条件下CCT 图所反映出的相变规律，因此为了提高焊接接头的性能，有必要深入研究真实焊接条件下热影响区组织的相变规律，尤其是马氏体组织的相变规律，因为在含碳量较高或合金元素较多的情况下，这两类钢的淬透性较强，在焊接热影响区极易形成高硬度马氏体组织，从而严重影响焊接接头的性能。

Two 15nt complementary ssDNA primers were ligated into double stranded satRNA.Complete sequence of satRNA was obtained by RT-PCR using these 15nt ssDNA as amplification primers.Phylogenetic analysis showed that the identity of this 383nt satellite and some documented satRNAs was 72.6 to 99.5% at the nucleotide level.

以常规引物对感病植物的总RNA进行RT-PCR扩增，获得CMV RNA3全长克隆，经测序显示该RNA3序列属于CMV亚组Ⅱ；通过在卫星dsRNA两端分别加上15nt的单链DNA接头，以接头互补序列为引物进行扩增获得一个383nt的卫星RNA的全长序列。

Further more, the simplified analysis method on stressed-skin effect of corrugated steel sheet is also discussed in detail.
