进行了大气压等离子体流动控制初步实验。

Elementary atmosphere plasma flow control experiment is performed.

大气压低于正常值的气团；常伴有降水。

An air mass of lower pressure; often brings precipitation.

在水面上用圆柱活塞加一个大气压的气压。

And I put a cylinder with one bar pressure on top.

“干燥器中”：采用五氧化二磷试剂干燥，大气压，室温。

"in a desiccator": the drying is carried out over diphosphorus pentoxide R at atmospheric pressure and at room temperature;

Xoom还提供陀螺仪，和测量大气压的晴雨表，当然HPPalmPad上也有陀螺仪。

The Xoom also features a gyroscope as well as a barometer for measuring the atmospheric pressure while the HP PalmPad has a gyro.
