管道中的

Lack of penetration is one of the main defects in piping. It is necessary to study the safety assessment engineering method of LOP not only in academic research but also in practice engineering.

未焊透缺陷是在役压力管道缺陷中存在的主要缺陷，研究其安全评定工程方法不仅具有重要的理论意义更具有重要的工程应用价值。

There are a number of hidden contributions to this work, beyond the construction of a fully verified, optimizing compiler: The compiler was built in a modular, pipelined fashion as a series of translations between well-specified intermediate languages, making it possible to add new optimizations or reuse components for other projects.

除了构造一个完全经过验证的优化编译器之外，这项工作还有一些更多贡献：采用了模块化、管道－过滤器设计模式，将整个编译器划分为一系列规范良好的中间语言之间变换的模块，这为加入新优化算法或者是在别的项目中重用这些模块提供了可能。

There were no false positive reports among the 220 (40.1%) biopsies interpreted as benign lesions in paraffin sections. Among 329 (59.9%) malignant biopsies on paraffin sections, 3 cases were interpreted as benign lesions on frozen sections. Three false negatives included 2 ductal carcinoma in situ and one infiltrating ductal carcinoma associated with papillomatosis. The tumors were small and confined to the breast without any evidence of metastasis.

本研究针对五年来本院 549 例乳房病理冰冻切片及永久性石蜡病理切片诊断比较，发现在 220 例的良性乳房病变40.1%）并未发现任何假阳性的冰冻病理切片诊断，而在 329 例（ 59.9 %）恶性乳房病变中，其中有三例假阴性包含二例乳房管道原位癌及一例合并良性乳突瘤的浸润性乳癌，而这三例均属较小病变及未有腋下淋巴腺转移。

Therefore, the detection of corrosion and defects in pipework is a critical problem in all fields of industries.

做好管道检测工作已成为各国所关注的重大课题，对这类结构的检测近年来也一直是该领域中设计、制造和用户密切关心的问题和检测难点。

The prefabrication and hoisting of steel structural tower are crucial work in oil and gas pipeline crossing.

钢结构塔架的预制和吊装是石油天然气管道跨越工程的关键，目前国内同行业中，尚无一套较成熟、完整、有效控制变形的施工方法。

As an effective method, pipelines play an important role in modern industrial, agricalture and people's life. It is called the fifth transport way except the highway, railway, water carriage and airway.

管道作为物流输送的一种有效手段在现代工农业生产和人民生活中起着重要的作用，是除公路、铁路、水运和航空以外的第五大运输方式，也被誉为生命线工程。

But the siphonic roof outlet of system has complex hydraulic peculiaritys、 high velocity of flow and limited capability of dealing with overflow. The error of any design might cause the system invalid or to be insiphonic, furthermore, it can lead to drainage hitch or make big noise, and overflow will appear when the rainfall exceeds the design value of tube. So we should make further studies to consummate the hydraulic peculiarity and the method of calculation continuously.

但虹吸式屋面雨水排水系统中防旋雨水斗的水力特性复杂和系统流速大、超泄能力有限，稍有不慎可能造成系统运行的失效，引起排水故障，或者产生很大的噪声，雨量超过管道设计值时还会出现溢流，从而需要对其进行进一步研究，不断地完善其水力特性和设计计算方法。

When people think of factories, they think of clouds of dirty smoke or a pipe pouring chemical waste into a river. They think of greedy businessmen hiding from their responsibilities to the environment and only thinking about money.

每当人们想起工厂，他们就会联想到滚滚烟尘，或者一根向河中倾泻化学废物的管道；他们就会联想到贪婪的商人躲避自己对环境的责任、一味追求金钱。

The selection of water supply pipe material, laying of pipeline, water gauge leading-out arrangement and noise rontrol in dwelling house design are discussed in this paper.

就住宅给排水设计中给水管材的选用、管道的敷设、水表出户设置及噪声的防治等问题进行探讨，并提出一些具体看法。

By the experiment studying, the relationship of ξ1, and v1 is determined. In a word, the water-power calculation of pipe can be done by taking corresponding ξ1, according to the design velocity v1 and .

通过实验研究，确定了ξ1与流速v1及A1/A2之间的关系，在设计中，只要根据设计流速v1与A1/A2就可以采用相应的ξ1进行管道的水力计算。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
