He included in his column of air the way convective updrafts carry heat up from the surface, a basic process that nearly every earlier calculation had failed to take into account.

在他的模型中，他加入了上升气流携带的热力的影响。这个基本的过程是几乎早期的每个计算方法都忽略了的。

One mechanism of temperature effect is that temperature influence water characters, such as surface tension and viscidity, the other one is that temperature affect on the quantity of air in experiment column.

温度对土壤水分运动和保持的影响一方面是由于温度影响水的表面张力和粘滞性，另一方面是由于温度影响密封土柱中空气的含量。

The narrow column of air which rests upon our shoulders weight almost 2,000 pounds. But our bodies are built in such a way that this weight does not crush us.

压在我们肩膀上的细空气柱子几乎重达2000磅，但是我们的身体的构造方式使得这个重量不会把我们压坏。

DOAS can be used not only to the measurement of air pollutants near the surface, but also to the measurement of column density of air pollutants, even in the global monitoring of air pollution by satellite instruments.

这种方法不仅可以用在大气污染气体浓度的近地面测量上，还可以用来测量大气污染气体的柱浓度，以及用到卫星仪器对大气污染状况的全球测量上。

A rapidly rotating column of air developed around a very intense low-pressure centre.

The law that the blasting effect varies with the length of bottom air column is analysed.

结果表明，底部空气柱长度与装药深度之比为0.4～0.8时，爆破效果最佳，爆破体积比传统的装药结构增大45％～55％，显著提高了炸药能量有效利用率。

The blasting effect of bottom air column charge is studied through a series of crater tests on cement mortar models.

本文通过水泥砂浆模型上的一系列爆破漏斗试验，研究底部空气柱装药的爆破效果，分析了底部空气柱长度变化对爆破作用的影响规律。

For example, if an open test tube with some water in the bottom is placed in a room in which the air is relatively dry, water vapor will diffuse out through the column of air in the test tube.

例如，当一支底部有水的开口试管被放置在一间空气相对干燥的房间里，水蒸气就会通过试管中的空气柱散布出来。

There had been a moment during the breakfast meeting, though, after the backslapping and the small talk and when all of us were seated, with Vice President Cheney eating his eggs Benedict impassively and Karl Rove at the far end of the table discreetly checking his BlackBerry, that I witnessed a different side of the man.
