Stayed cable is very vulnerable to vibration as it is with low rigidity, low damping ratio and light weight.

由于斜拉索刚度小、阻尼低、质量轻，极易发生振动。

The high coefficient of thermal expansion and low rigidity of many plastics increases the risk that the pipe will lose its dimensional stability.

很多塑料的热膨胀系数高、刚性低，这增加了(塑料)管道失去空间稳定性的风险。
