容器的破坏型式主要有塑性破坏、疲劳破坏、应力腐蚀、脆性破坏和蠕变破坏。

钢材的破坏形式有（）、脆性断裂和疲劳破坏。

钢材具有两种性质完全不同的破坏形式，即塑性破坏和脆性破坏。

结构钢材最易发生脆性破坏的应力状态为（）

Every deliberate act of wrongdoing by the master or any of the crew against the ship or cargo，without the authorization or privity of the Shipowner or his agent，is（）.

（）, or drum is used for hauling in or letting out the wires or ropes which will fasten the ship to the shore.

Vessels must be（）valid certificate of nationality or certificated of registry or license.

逻辑运算符（AND、NOT、OR）的运算顺序是AND→OR→NOT。

脆性破坏的特征是在破坏之前钢材的塑性变形很不明显，有时甚至是在应力小于屈服点的情况下突然发生，这种破坏形式对结构的危害比较大。
