管道

The transducer, which is coaxially connected with the transport pipeline, does not disturb the flow state and has the features of ruggedness and durability, it is especially suitable for industry process control.

基于极化电荷的流量传感器不仅结构简单、寿命长，而且与气输管道同轴密封连接，不影响粉粒体在管道中的流动状态，因此特别适合于工业过程控制。

Due to the corrodibility of soil and roughness of corrosion protection presently, old fuel gas pipes in Shen Zhen suffer severe corrosion, confronting a great deal of accidents after more than ten years' running.

摘要由于深圳土壤的强腐蚀性和当初防腐工作的粗糙和不完善，深圳旧燃气管道遭受严重的腐蚀，经过十多年的运行，腐蚀老化严重，已经到了事故多发阶段，因此对旧燃气管道进行防护势在必行。

The actual CP effectiveness of Ma anshan and Wuhu pipeline suffered stray interference was well. The soil corrosibility distribution along the pipeline was obtained. IR-drop statistical value of 170mV was obtained to revise protection potential criterion that is substituting -1.02V for -0.85V.

经过检查片设计、试验方案实施以及数据处理分析，得到了管道沿线阴极保护度和土壤腐蚀性分布；获得该地区IR降误差的统计值为170mV，并修正了管道保护电位准则（以－1.02V替代－0.85V）。

Struma Cuvier consists of three parts: digenetic gland, the reproductive ducts and subsidiary glands of male, the reproductive ducts and subsidiary glands of female.

雄性生殖管道由输精管、阴茎、刺激器组成，附性腺为主要的附属腺体；雌性生殖管道由输卵管、受精囊、阴道组成，附属腺体主要为卵黄腺和蛋白腺。

T he b iggest v alue o f a xial t ensile s tress i n c oncrete u nder t he a ction o f w ater p ressure a nd thermal load could be as high as 4.23MPa, which will lead the occurrence of circumferential cracks. So reinforcement along the axial direction must be laid.

在常规荷载和温降荷载共同作用下，斜直管段混凝土最大轴向拉应力可达4.23MPa，已经远远超过了C25混凝土的设计抗拉强度1.3MPa，在管道混凝土内可能出现环向裂缝，因此在进行管道轴向配筋时应采取一定工程措施。

So it is urgent to find a method todetect underground pipeline and its branches conveniently. In order to solve the above problem, based on the fact that the heated petroleumradiates heat to the soil and then the especial temperature distribution will be formedon the ground, this paper reach out a method creatively using the infrared imaging todetect the underground pipeline.

本文的研究内容正是从这一实际需求出发，根据石油在管道中传输时因加热而向周围土壤辐射红外能量，进而在管道上方地表形成特殊的温场分布的特点，创造性地提出了用红外热成像技术来检测埋地输油管道方法，并重点完成了几下几方面工作。

RESULTS After disinfection all parts of device including its cap, outlet, inner surface of pipe and outer wall were germfree.

Drainage is not set for the water inlet valve of the baby's pool on 9 F, which can result in helminthes.

9层游泳池里面的戏水池进水阀们没有安装排水管道，里面的积水不能及时排出，滋养寄生虫，戏水池里面的排水沟地漏应加有滤网，防止杂物对排水管道的影响

These tubes are hydrostatically tested by the manufacturer but, unlike cylinders and mobile tubes, periodical hydrostatic testing is not required.

这些管道经过了制造商的流体静力学测试，但是和钢瓶和移动管道不一样，它们不要求定时的流体静力学测试。

All piping shall be hydrostatically tested to the minimum pressure specified on the line lists or by Code, but not less than 103 kPa except piping excluded or modified herein.

所有管道均应在管线表或规范规定的最低压力下进行液压试验，试验压力不得低于103 kPa，未包含在本技术条件中或经改造的管道除外。

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.

其基本内涵可概括为：以确有疗效的中药复方为研究对象，以现代科学技术和传统中医药理论为技术支持，以该复方所治病证的药效响应为评价标准，以优化重组疗效更优的新复方为研究目的。

Ever since our world has been a world, native forests have been indiscriminately exploited by man.
