查询词典 column foot

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.

中文解释=在非常强烈的低压中心周围所发展的快速旋转气柱。

A device in a brass wind instrument that permits change in pitch by a rapid varying of the air column in a tube.

活瓣在铜管乐器中通过在管中迅速改变气流而完成音调的改变的一种装置。

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。

On line measurement of pulsed column parameters by air purge is studied.

用吹气法在线测量脉冲萃取柱参数。

Although there is 34,500 tons of gaseous nitrogen in the air column above each acre of the earth's surface, this cannot be used by plants until it has been fixed by nitrogen-fixing bacteria and algae.

虽然在地球表面每英亩空气柱中有34，500吨气态氮，但是如果这些气态氮不被固氮菌和藻类固定，是不能被植物利用的。

A tornado is a violent, rotating column of air which is in contact with both the surface of the earth and a cumulonimbus cloud.

龙卷风是一种暴力，旋转柱空气接触而同时与地球表面和积雨云。

And, of course, we in the press will abet the hype because it's about conflict, which is the motor fuel of storytelling, and because we need to "sell" the story in order to win air time and column inches.

当然我们新闻人会鼓动瘾君子，因为这是冲突，是谎话的源动力，因为我们需要"售卖"故事情节去赢得时间和观众。

It is suggested that TDS can be used as a new method for the analysis of pedogenesis and climatic change.

总之，热处理过程中磁化率的变化能非常灵敏地反映磁性矿物的转化情况，而且，这种转化往往与样品所经历的土壤化作用强度密切相关，因此，TDS可做为分析成土作用强度和古气候变化的一种新方法。

Therefore, in this chapter, I will research into the conflict and contradiction of the paternity. Also, in this novel, the father's behavior of "He who loves well chastises well." is quite suspicious, one of the reasons is that the father thought his son belonged to him. And then, this thesis quoted Lacan's theory to touch upon that someone who has accepted the concept of patriarchal society, he will be influenced for his whole life. That also reveals that human being has no choice sometimes in this society.

因此本章会先就父子关系的冲突与矛盾做深入的探讨，小说中的父亲似有对儿子爱之深责之切的行为，其原因可能在於父亲将儿子视为所有物所致；其次，论文将引用拉冈相关理论，讨论在父权社会中，不论身分为何，只要是已受父权社会观念根深蒂固影响的人物，终生都将受其所苦，此也揭示出人生存於社会上的无奈。
