contraction crack

基本解釋

The text has analyzed the mechanism of contraction crack on the surface of ceramic . fibre.
分析了纖維收縮産生裂紋的機理。
Sensitivity coefficient obtained from calculation can represent how much the internal temperature variation and contraction affects the early crack of concrete structure.
