油管

A number of factors areconsidered including the pressure wave and the viscous resistance in the highpressure oil pipe and the changes of flow areas in the high pressure oil chan-nels.

讨论中考虑了高、低压油管内的压力波动和粘性阻力，以及高压油通道截面变化等因素的影响，同时，对系统中出现的"空腔"现象也作了适当的处理。

WE NEED TO BUY AUTO VITTA ,PLEASE AND CONTTACT US .

我们需要求购汽车油管，请与我们联系。

Research on photoelectric measurement of the vitta′s position［J］.

Character:Mark big object,for example batholith,vitta

特点：打印大型工件，如汽车底盘，油管等

Disc brake , as the name suggests, the shape is like a disc and its main parts include brake disc, wheel cylinder, brake caliper and vitta etc.

盘式制动器又称为碟式制动器，顾名思义是取其形状而得名：它的主要零部件有制动盘、分泵、制动钳、油管等。

Affected by the hydraulic pressure sent from the vitta, the wheel cylinder piston pushes the friction plates and makes them press down on brake disc so friction braking can be achieved. The working principle is like griping a rotaty plate with a clamp and making it stop.

分泵的活塞受油管输送来的液压作用，推动摩擦片压向制动盘发生摩擦制动，动作起来就好像用钳子钳住旋转中的盘子，迫使它停下来一样。

It chooses the vitta, the pump, and the sucker-rod assemblage in reason from the dimensionless quality curve, and the sucker-rod assemblage sheet.

以产量为目标根据无量纲参数曲线、抽油杆柱组合数据表来合理选择抽油泵、油管、抽油杆柱组合，并对工作状态进行预测。

The author stops crock of test, engine response is sensitive, chase a crock to try high-pressured vitta with the hand, have apparent pulse feeling, explain job of high-pressured oil path is regular.

笔者断缸试验，发动机反应灵敏，用手逐缸试高压油管，有明显的脉冲感，说明高压油路工作正常。

November 2001, the vitta below the well ruptures, the pressure below the well appears unusual, this year in January, flat aggravate -- if do not take strong step, cause malign accident extremely likely, destroy Chuanxide finally the big gas field with area the richest gas pool, make people life property is damaged badly.

四川德阳市境内中国石化控股的新场气田中的新851井，是2000年10月投产，日产天然气40万立方米的高产气井。2001年11月，井下油管断裂，井下压力出现异常，今年1月，漏气加剧——若不采取有力措施，极有可能造成恶性事故，最终破坏川西地区气藏最丰富的大气田，使人民生命财产受到严重损害。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
