Human's life is limited, but does laundry for the family member the work is infinite, so long as is willing to wash, the dirty clothes always have, in such work atmosphere, when the man full head hot perspiration, passes through an outstanding struggling hard, looks the flag of all nations resembles clothes hang all over dries in the sun clothes pole's time, the man had realized unconscious has borne hardships and stood hard work the work pleasure which brings.

人的生命是有限的，可是为家人洗衣服的工作是无限的，只要肯洗，脏衣服总还是有的，在这样的工作氛围中，当男人满脑瓜子热汗，经过一番卓绝的苦战，看着万国旗似的衣服挂满晾衣杆的时候，男人已不知不觉地体会到了吃苦耐劳带来的工作乐趣。

Originally Maurel et Prom approached Colfax about supplying progressive cavity pumps for oil-warming stations and transporting oil to cleaning systems.

MaureletProm原本只采用了科尔法的适用于平稳油区的螺杆抽油泵，输送原油到清洁系统中。

Colfax engineers demonstrated to Maurel et Prom officials that rotary positive displacement screw pump technology would be 50% less expensive to buy and operate for transporting viscous crude oil from the production field.

科尔法工程师向MaureletProm石油公司证实，偏远地区选择适用螺杆泵，能将高粘度原油从油田中运送出去，同时节省50%的采购成本。

MPlayer has a fully configurable, command driven, control layer which lets you control MPlayer with keyboard, mouse, joystick or remote control.

在控制层中，几乎所有的选项都是可控制的。使用者可以用键盘、滑鼠、摇杆、遥控器。

The simulation results show that the rod baffles placed vertically and horizontally in the unit duct continuously shear and comminute the streamlines of the flow when the fluid crosses over the rod-baffles, change the fluid flow directions, and result in the disruption of the continuity and stability of the fluid. The disturbing flow can promote the fluid turbulent intensity and effectively enhance the heat transfer.

结果表明，纵横交错布置的折流杆在单元流道中不断分割和剪切流道内流体，其扰流作用促进了流体湍流，减薄了液体边界层，减小了对流换热热阻，因而有效地提高了流体的对流换热强度。

The geometrical compatibility condition of the rod was analyzed.
