The velocity distribution curve by numerical computation near the wall is the same as the Blasius theoretical curve, and it approved that the numerical simulative solution is correct. Obtained the time dependent interface and pressure distribution, but also obtained the time dependent velocity distribution on the cross section. It is a new way to study the gas-liquid two-phase flow.

直接数值模拟圆管中气液两相分层流动不仅能得到相界面、压力分布随时间的变化情况，而且能得到圆管中各截面上速度分布随时间的变化情况，这为研究管道中气液两相流动提供了一个新的研究方法。

When the proper temperature is reached, the alloy will flow readily into the space between the tube outer wall and the fitting socket, drawn in by the natural force of capillary attraction.

当温度加热到一定程度，合金将流到管道外壁和管件插口内壁之间的空隙中，这种吸入作用是通过毛细吸引的自然力实现的。

With this method, the soil is dumped into a pit, which has been dredge d previously, and is dumped up by a plain suction dredge r. This dredge r then pumps it ashore through a floating and fixed pipe.

使用这种方法时，先将淤泥倒入事先挖好的坑中，然后使用吸泥机，通过漂浮在水中、并加以固定的管道将淤泥吸到岸上。

Most of them are in small-diameter and middle-diameter, which are located in densely populated areas. Once the leaks happened, the damages are more serious.

我国大量的中、小口径油气输送管道分布在人口较稠密的地区，一旦发生腐蚀泄漏事故，其后果将更为严重。

A method based on the resistance-displacement relationship of shape memory alloy spring that can adjust the nonaxiality of small-diameter pipe inner surface inspection sensor is proposed.

根据记忆合金弹簧的电阻和回复位移一一对应的特性，提出了一种微细管道形貌检测器对中方法。

The name of the tape comes from the fact that it was designed as an insulating tape that can be used in duct work (channels or conduits that are used for heat to travel through to get to different areas of a building).

在西方，多数人的工具箱中，你可望找到一把锤子和一些钉子，一把钻子，几把螺丝刀和一些螺丝钉。不过，你要是问北美人什么是他们工具栏里最有用的东西，多数人会肯定地告诉你那是管道胶带。

However, in reality there are still a number of malpractices in protecting the legal rights of pipeline riders.
