water vapor

【TPO例句】

1. And then it snows because as the air rises, it cools off and loses its capacity to hold water vapor. (TPO24-C2)

所以接着就会下雪,因为随着空气的上升,温度降低,从而失去了对水蒸气的控制。

2. And from what I remember, water changes back and forth from water in lakes and oceans to vapor, and then back to water again when it falls as rain or snow, as precipitation. (TPO24-C2)

根据我的记忆,水是来回循环 的,湖水和海水变成水蒸气,然后水蒸气又变成雨或雪落下,也就是降水。

3. Um, water vapor? Carbon dioxide?(TPO40-L3)

水蒸气?二氧化碳?

4. With all the water vapor gone, the greenhouse effect would no longer have accelerated.(TPO41-P2)

所有水蒸气都消失了,温室效应也就不会加速了。

5. Since water vapor is a greenhouse gas, this humid atmosphere—perhaps denser than Earth’s present-day atmosphere, but far less dense than the atmosphere that envelops Venus today—would have efficiently trapped heat from the Sun. (TPO41-P2)

由于水蒸气是一种温室气体,这个潮湿的大气层——可能比地球现在的大气层厚,要比现在笼罩的金星的大气层薄得多——可以有效地留住来自太阳来的热量。

6. But if water vapor and carbon dioxide were once so common in the atmospheres of both Earth and Venus, what became of Earth’s carbon dioxide? (TPO41-P2)

但是,如果水蒸气和二氧化碳在地球和金星的大气中曾经如此普遍,地球的二氧化碳去了哪里?

7. Thus water vapor would have been able to liquefy and form oceans on Venus. (TPO41-P2)

因此,水蒸气能液化并在金星上形成海洋。

8. The gases that emanate from present-day volcanoes on Earth, such as Mount Saint Helens, are predominantly water vapor, carbon dioxide, and sulfur dioxide. (TPO41-P2)

来自现如今地球上的火山(例如圣海伦斯火山)的气体主要是水蒸气、二氧化碳、和二氧化硫。

9. And the heat energy that was stored in the water vapor is released into the new environment. Okay? (TPO47-L4)

在水蒸气中储存的能量在新环境中得到释放。明白了吗?

10. Then the air, the wind, transports the water vapor to some other part of Earth. (TPO47-L4)

然后空气/风把水蒸气运输到地球上其他部分。

11. But that heat energy, that conversion energy, doesn't raise the temperature of the water vapor or the air, it's just stored in the water vapor. (TPO47-L4)

但是那部分热量,转换的能量,不提高水蒸气或空气的温度,它只是储存在水蒸气中。

12. So when the air moves, it carries the vapor with it to some other parts of Earth, where it can deposit it as rain or snow, or some other form of precipitation. (TPO47-L4)

所以当空气移动的时候,它带着蒸汽到地球上的其他地方,那里它以水或雪的形式沉淀,或其他降水形式。

13. Water's contained in the air in the form of vapor, mostly through evaporation, mostly from the oceans. (TPO47-L4)

水灾空气中以蒸汽的形式存在,主要通过蒸发,大部分来自海洋。

14. Water vapor condenses onto these particles when the relative humidity is as low as 70 percent, forming haze that greatly reduces visibility. (TPO48-P3)

当相对湿度低至70%时,水蒸气凝结在这些粒子上,就会形成阴霾,大大降低能见度。

15. Each time the snowflake encounters water vapor, more molecules attached to it, leading to more and more complex structures.  (TPO52-L3)

每一次当雪花遇到水蒸气时,更多的水蒸气分子会附着其上,这就形成了越来越复杂的结构。

16. And when it encounters water vapor, molecules from that vapor attached to each of the six sides.  (TPO52-L3)

当它遇到水蒸气的时候,水蒸气分子就会附着在六道边上。

17. And that water vapor condenses directly into ice, into an ice crystal.  (TPO52-L3)

水蒸气会直接凝结成冰,凝结成冰晶。

18. Well, you start with water vapor. (TPO52-L3)

嗯,我们要从水蒸气开始说起。
