热胀系数 meaning in Chinese

thermal co

Coefficient of linear thermal expansion
线性热胀系数
Results show that the brittle fracture is mainly caused by hydrogen brittleness that results from the oxidation arid absorbing hydrogen of copper tube during braze welding
同时在加热和冷却时，由于异种材料的热胀系数差别过大，产生的较大热应力作用于已存在的裂纹，促使裂纹二次扩展，甚至使得晶粒脱落产生空洞，最终导致焊接接头漏气失效。
We research on the thermal buckling characteristics of double layer membrane which is composed of different materials with different thermal expansion coefficiens under uniform temperature elevation . the energy method is proposed which is used to solve the problem and the symbolic relation between central buckling height and substrate height under small buckling height is also given . it is the primary theory of membrane resonant sensor , which makes the research and development of novel thermal sensor possible
本文对微机械中热胀系数不同的材料构成的双层复合薄板在均匀温升下的挠曲特性进行了研究，提出了在均匀温升下双层薄板热挠曲求解的能量法，并给出了小挠度下中心挠度与板厚的解析关系，为薄膜谐振式传感器温度特性的研究和新型温度传感器的设计与开发打下了基础
