One of the main objectives of this study is to develop a generic thermo-mechanicaldurability model for Pb-free solders.
这项研究的主要目标之一是建立一个通用的热机械为无铅焊料的耐久性模型。

Aerogel material has lower thermal conductivity and performs best in the atmosphere of Mars, but the problems of dust control and mechanicaldurability cannot be avoided.
The design of tower structures foundation is more complicated than common structures, and it is difficult to study tower structure mechanicaldurability and diagnose its defects.
