Then the flow regime in the wells is studied.Firstly, the energy dissipation engineerings are systematically concluded. Then circular stilling well hydraulic model is made.The paper presents guidelines to aid the designers in determining optimum well geometry for their specific needs. General design criteria have been established to determine well size based on design discharge, Q, and diameter of the standard sleeve valve, D.

本文首先较系统地总结了消能工的研究现状；设计制作圆形深筒式消力井水工模型，通过试验及数据分析建立了圆形深筒式消力井各变量间的函数关系式，得出圆形深筒式消力井水力设计的基本方法，即已知设计流量和进水管直径，由曲线可得到圆形深筒式消力井的最优尺寸，并运用工程算例进行验证。

He threw a t-shirt into the bathroom hamper and then took a clean dress shirt from the dresser. He checked himself in the mirror as he buttoned it. Unruly hair, but not excessively long. Clear, fair skin, and smooth for a change; he was happy he'd shaved that morning. He was a little on the bony side around the neck and shoulders, but not without some muscle tone.

他把那件T恤衫扔进卫生间的衣物篮里，从衣柜里拿出一件干净的衬衣穿上，系上扣子，照照镜中的自己：头发乱糟糟的，还好不算太长；干净洁白的皮肤，光滑细腻；他庆幸早上刚刮过胡子，脖子和肩膀处的锁骨棱棱凸起，没有松弛的肌肉。

Identification and selection of dominant vibration-modes contributory to wind-induced vibration response for large-span space lattice structures;2. The wind-induced vibration response of single-layer cylindrical shells is analyzed by frequency domain method in this paper.

运用频域分析法对单层筒壳进行风振动力响应分析，在基本参数(阻尼比参数、地貌参数、几何参数、支座高度参数)的常用变化范围内，进行大量的算例计算，然后对所得的计算结果进行统计分析，考察各参数对单层筒壳的风振响应及风振系数的影响，在此基础上提出单层筒壳抗风设计的实用方法。

By three-dimensional linear standing wave,the wave propagation over a bar of scheldt flume experiment carried at Delft hydraulics and tidal current field simulation of waters of between Denmark and Sweden etc example,the model is verified to have advantages such as stability, high efficiency etc,and proved suitable for the simulation both water body of large range and long period.

最后通过三维线性驻波、Delft水力学中Scheldt水槽实验的周期性入射波通过淹没潜堤的传播问题以及连接丹麦和瑞典间海域的潮流场模拟等算例，从多方面验证了模型具有稳定、实用、高效、灵活等的优点，不但能对短波问题进行精确成功的模拟，而且也适合对大范围的水体进行长时段的模拟。

We've been dumping green stuff in the river for years.

这些年，我们到进河里的绿色废料还算少么？

I'm strongly against the death penalty — it's an eye for an eye.

我不赞成死刑——这是以牙还牙的报复行为。

And to get you the support you need, we're enlisting all elements of our national power: our diplomacy and development, our economic might and our moral suasion, so that you and the rest of our military do not bear the burden of our security alone.

并给你们所须的支援，我们正徵召国家所有各种的力量：我们的外交及发展，我们的经济力量与道德劝说，所以你们与其他军人不须要孤独地负起国家安全的责任。
