Not all of that steam could be solar, but a system which used high-pressure solar steam during the day and low-pressure gas-generated steam by night, to keep the pipes hot, might get 80% of its power from the sun.

并非所有蒸汽来自太阳能，而是来自一个系统。白天，这个系统使高压太阳蒸汽，而晚上使压天然气产生蒸汽，保持管道热乎，或许80%能量可从太阳光获得。

Meteorologists say this series of rainstorms were part of two low-pressure weather systems causing stormy conditions enhanced by moisture coming off of the Mediterranean Sea and running up against Spain's coastal mountains.

气象学家表示，这一系列暴风雨是两个压天气系统一部分，而来自地中海、受到西班牙沿海山脉阻挡水汽增强形成暴风雨天气条件。

Ehlmann and her team previously identified metamorphic rocks on Mars that she thinks could have formed when hot groundwater circulated through rocks buried underground, a relatively low-temperature, low-pressure process.

埃尔曼和她团队之前在火星上发现岩，她认为这些岩可能是热地下水在埋藏于地下岩石中循环时形成，这是一个相对温、压过程。

A low-pressure system developing over the central U.S. on Sunday will slide eastward in the coming days, bringing the chance of rain, snow, high winds, and even possible tornadoes.

周日在美国中部地区形成压系统将在未来几天向东移动，有可能带来雨雪、大风，甚至可能出现龙卷风。

Several climate scientists and meteorologists said the immediate cause of the flooding is a cut-off lower pressure storm system that came from an unusually wavy and slowed jet stream.

几位气候科学家和气象学家说，洪水直接原因是一个被切断压风暴系统，它来自一个异常波动和缓慢急流。

Sean Hogan from Reuters reports. The low pressure system named Boris has wreaked deadly havoc across central Europe, causing the worst flooding in more than two decades.

路透社记者Sean Hogan报道。名为鲍里斯压系统给中欧地区带来致命破坏，造成20多年来最严重洪水。

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，或者声波在空气中产生高压和压之间差异。

A 2016 study by weather scientists suggested that low-pressure storms from the Pacific Ocean bring rain and snow to Chile in the winter under normal conditions.

气象科学家2016年一项研究表明，在正常情况下，来自太平洋压风暴在冬季会给智利带来雨雪。

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，还有可以固定在一个地收集压电力小螺丝管。

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，高压和压位置。

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

从地理角度看，加拿大上空高压系统和其东部压系统相互作，将烟雾送往南。

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

But we also have this very deep trough that is set up over the United States.

但同时美国上空又存在一个非常深压槽。

It takes precise coordination to create the high and low pressures required to pump your blood after all, and cardiac cells need to be linked in order to have that perfect timing.

毕竟，创造泵送血液所需高压和压需要精确协调，心脏细胞需要联系起来才能有完美时机。
