During the working process, it bears thermal and mechanical loads simultaneously, because of which it tends to crack and even break.
它在工作过程中，受到热负荷和机械负荷的共同作用，工况恶劣，容易产生裂纹而导致破坏。
The method avoids the problem that the wafer break is caused by thermal stress in the course of cooling down, especially is suitable for preparing gallium nitride and aluminum nitride substrates.
该方法避免了降温过程中热应力造成的晶片破裂问题，尤其适于氮化镓、氮化铝衬底的制备。
The thermal fatigue crack propagated mainly through the break-age of the interface of carbide and grain boundaries for either quenched or quenched and tempered steel.
无论是淬火或淬回火态的试样其热疲劳裂纹主要沿着碳化物与基体脱开处及晶界裂纹桥接而扩展。
Low density, low particle strength, good thermal property itself, but break easily while mixing, and reduce thermal property.
容重轻，颗粒强度低，本身有较好的热工性能，但在砂浆搅拌过程中容易破碎，会很大程度降低其热工性能。
The utility model has the advantages of high bearing, high thermal efficiency, etc., and the inner tube is not easy to break.
本实用新型具有承压高、内管不易破碎和热效率高等优点。
