Depends on when we have these large dips in the jet streams, placement of the high pressure and low pressure.

取决于喷射流大倾角，高和位置。

But due to the presence of low-pressure zones, these winds follow a circular path.

A tragedy has been caused by a tropical depression which brought days of heavy rain in several provinces.

这场悲剧是由热带引起，给几个省份带来了连日大雨。

When tropical cyclone is an area of low pressure that forms in the tropical regions of the world.

And the casualties of low-pressure fronts simply move on-gingerly.

锋过境造成伤亡人数持续增加，请小心。

So when we're harvesting geoduck, we use low pressure, high volume water.

因此，当我们收获象拔蚌时，我们是大容量水。

But in higher winds, they create alternating low pressure zones that make the building rock back and forth.

但大风中，它们会形成交替区，得建筑石头来回摇摆。

But considering its dry, low-pressure atmosphere, snow barely reaches its surface, and never stays for very long.

但考虑到其干燥、大气层，雪几乎无法到达其表面， 而且永远不会停留很长时间。

Line spectra work for heated gases under the right low-pressure conditions.

线谱适于 正确条件下加热气体。

So with low pressure levels at this height and above, your blood boils.

因此，这个高度及以上水平下，你血液会沸腾。

This results in tremendous low-pressure areas.

这导致了巨大区域。

Climate patterns related to high and low pressure systems are what push large storms in certain directions.

与高和系统相关气候模式是将大风暴推向某些方向原因。

However, it seems the most plausible explanation was a perfect  storm of dry conditions and a strong low-pressure system.

然而，最合理解释似乎是一场完美干燥风暴和强大系统。

Geographically, the interaction between a high-pressure system over Canada and a low-pressure system east of it have sent the smoke south.

从理角度看，加拿大上空高系统和其东部系统相互作，将烟雾送往南方。

The diaphragm can do this thousands of times a second which creates cycles, or an oscillation, of high pressure and low-pressure waves.

横膈膜每秒可以进行数千次这样运动，从而产生高和波循环或振荡。

But if you listened for 8 consecutive hours, this relatively low-pressure sound would overwork the stereocilia and swell the hair cell's supporting tissue.

但如果你连续听 8 小时，这种相对声音会静纤毛过度劳累，并毛细胞支持组织膨胀。

You know, standardized platform with the motors and the battery when it operates, little solenoids that will lock it in place and get low-voltage power.

还有带着发动机和电池标准平台，还有可以固定一个方收集电力小螺丝管。

How loud a sound registers depends on the wave's amplitude, or the difference between the high and low pressures created in the air by that sound wave.

声音大小取决于波振幅，或者声波空气中产生高和之间差异。
