钎焊接头

In this dissertation, joints of single crystal Al2O3 and Nb were prepared by tungsten metallization and Pd brazing.

本文通过钨金属化和Pd钎焊，成功获得了单晶Al2O3与金属Nb的连接接头。

In order to decrease the residual stress in the joint, the impartance of considering the properties and thickness is the same as considering the wettability and interface reaction.

在选择金属／陶瓷钎焊用钎料时，为降低接头残余应力，除考虑钎料与陶瓷的润湿性和界面反应程度外，钎料的性能参数和厚度同样重要。

Moreover, microstructure of brazed joint with BNi-2 filler metal is studied by means of metallographic microscope, SEM, EDAX and so on.

通过金相分析、扫描电镜和 X射线能谱分析等手段，研究了BNi-2钎料钎焊不锈钢时的接头组织。

And for brazing, the quality of welding connector has much to do by thewelding temperature in the welding course.

而对于钎焊来说，焊接接头质量的好坏，与焊接过程中的温度有很大的关系。

On the other hand, if Ti foil is too thick, the interfacial reaction between liquid Cu-Ti alloy and Al〓O〓 ceramic can proceed sufficiently, due to the widening of the liquid phase region. This results in a too thick reaction layer, which also reduces the joint strength. Further more, in this situation, not all of the liquid alloy is isothermally solidified, similar to the case of brazing, the heatresistant of joint can't be improved.

相反，Ti箔过厚，一方面由于液相区宽度增大，连接过程中始终为Cu-Ti液体合金与陶瓷反应，导致形成过厚的反应层，降低接头强度；另一方而，由于连接后液相区未能完全等温凝固，与活性钎焊相类似，接头耐热性也难以得到提高。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
