夹层材料 meaning in Chinese

sandwich material
sandwiched material

A new technology for bonding stainless steel / carbon steel with intermediate sandwich material is proposed
研究了中间夹层材料和保护气体对不锈钢与碳钢复合效果的影响规律。
The influence of intermediate sandwich material and shielding atmosphere on the stainless steel / carbon steel bonding was studied
摘要提出了利用中间夹层材料促进不锈钢与碳钢复合的新工艺。
The stainless steel and carbon steel can be excellently bonded under lower pressure by using silver intermediate sandwich materials and the oxide film on stainless steel can be destroyed effectively by argon gas shielding in the heating process
结果表明，采用自制的银基中间夹层材料可以使两种母材在较低的压力下实现良好的复合；加热过程中采用氢气保护能够有效地去除不锈钢表面致密的氧化膜。
Finally , the stress and strain distributions of dam foundation in which there have glacis weak surfaces are studied by means of nonlinear fem . with deducing parameters of weak surfaces gradually , stability of the dam against deep sliding is verified . therefore safety of dam and foundation would be estimated
5 、运用非线性有限元法研究了东张水库重力坝含有缓倾角软弱夹层的坝基应力、应变情况，用逐步降低夹层材料参数的方法核算大坝的抗滑稳定，以此评价大坝及坝基的安全性。
