Subsequently, the effects of subgrade freeze-thaw condition, running speed and width of rail gap on the vibratory load from trains were investigated.

据此，研究了北麓河试验段路基冻融状态、列车行驶速度、轨缝宽度对路基列车行驶振动荷载的影响。

SPVC (Soft Polyvinyl-chloride): Using this elastron for jacket manufacturing ensures the sufficient flexibility of the cable construction and additional decrease of vibratory load.

（柔性的聚乙烯氯化物）：用这种elastron制作护套可以保证线材有足够的柔韧性，并且还能降低振动负载。
