以双U形地埋管换热器为例，进行了3个不同季节的地下热响应换热实验。实验结果表明，在地埋管换热器地下热响应实验中存在着季节效应。

Based on the oil-water flow rate and density obtained with a double-U Coriolis flow meter, and by the help of Support Vector Machine, a direct prediction method of the oil-water respective mass flow rate was developed to avoid the need of study on the complex relation between the slip velocity, water hold up and water fraction.

以双U型Coriolis流量计得到的油水混合物的质量流量和密度为基础，提出了基于支持向量机油水分相质量流量的直接预测方法，避开了直接对滑脱速度、持水率与含水率等之间复杂关系的研究。

In order to overcome the difficulties in measuring the flow rate of oil-water two-phase flow, the measurements of total mass flow rate, respective mass flow rate and real density of oil-water mixture with a double-U Coriolis flow meter were investigated.

针对油水两相流流量的测量难题，采用双U型Coriolis流量计对油水混合物的总质量流量、分相质量流量和真实密度进行了测量研究。

一种用来盛液体的并且用来防止污气回流的排水管的u-形部分。

By adjusting the producing technics of PVC-U drainpipe , the impact property is effectively improved.

通过对PVC-U 排水管材生产工艺的调整，有效地提高产品的冲击性能，在实现有效控制成本的同时，最大程度地满足用户对产品冲击性能的要求。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
