The rail welding plays an important role in the engineering of laying continuous welded railway (c WR), and decides the quality of rail tie-in directly, which has great influence on railway security.

钢轨焊接是无缝线路建设工程中的关键环节，它直接决定了钢轨接头的质量，从而对铁路安全有重要影响。

As well as performing minesweeping missions, the Type 6610 could also be used for mine laying role, carrying a mine rail and 8 ~ 10 naval mines on its stern deck.

除了履行扫雷任务，6610型也可以用于水雷布设，在舰尾甲板上装有一具布雷导轨和8 ~ 10枚水雷。

The method comprises the following steps: A. laterally laying the rolled rail on a collection bracket for cooling;

该方法包括如下步骤：A。将轧制出的钢轨侧放在收集台架上进行冷却 ；

The rate of rail creep lengthening at the beginning after rail laying on the track is greater than that of the afterward time.

新钢轨上道后的前期，蠕变伸长速率较大，以后逐步降低。

It is also raising fares for weekly and monthly passes, cutting rail services by 14.2% and laying off around 300 people.

而且还会提高周票、月票的价格，减少14.2%的铁路服务，并裁员300多人。

The rate of rail creep lengthening is not the same at the different time after the new rail laying on the track.

得出新钢轨上道后的不同时期，其蠕变伸长速率是不同的。
