Result calculated by the mathematics model indicates that pipeline capacity decreases as the length of pipeline increases and reliability of pump unit reduces.

该数学模型计算的结果表明，管道的输送能力随泵机组可靠度的降低和管道长度的增加而减小。

Meanwhile, the influences of pipeline internal pressure, wall thickness, crack arrest length and initial crack velocity on the crack driving force (crack propagation) are further studied.

进而分析了管道内压、壁厚、裂纹止裂长度和初始裂纹速度对裂纹驱动力(也即裂纹扩展)的影响。

The length of the pipeline is on fire about 200 meters, fire officers and soldiers while cooling oil reserves in the tank with cold water, while fire-fighting foam.

正在着火的管道长度大概在200米左右，消防官兵一边在用冷水冷却原油储备罐，一边用泡沫灭火。

"If we find a mine, we inform the national authority, and we would re-route the pipeline, " he explains, adding that the real challenge is the length of the pipeline, the shallow nature of the Baltic Sea and the irregular seabed.
