气压

This is problematic because the implementation we had in mind was to have the TemperatureCalculator look up the current pressure by accessing The Weather Channel over the network.

这是有问题的，因为我们脑袋中拥有的实现是让 TemperatureCalculator 进入天气频道的网络查找当前气压。

The US National Hurricane Center says John is barely above the threshold for a tropical storm now and will lose strength and become a tropical depression later in the day.

美国国家飓风中心说约翰几乎是高于目前热带风暴，将失去力量在今天晚些时候成为热带风暴低气压。

The result showed that the strong storm followed by mesoscale squall line was primary cause of strong sandstorm producing, steps and ladders short wave trough of 500 hPa was great criterion triggering system for the mesoscale squall line producing, the essential dynamic condition was provided by distortion field and the mesoscale low pressure of 700 hPa for the strong sandstorm forming and maintaining in mid-west of Hexi Corridor, the deep vertical circulation development condition was basic power that urged squall line to occur and sand dust to curl up, which was provided for the deep convection development by superimposition of lifting movement before ground cold front and ascendant current of secondary circulation in upper air jet entrance region, temperature and the barometric gradient around the cold front was enlarged by enhancement of ground thermal low and temperature diurnalvariation of afternoon, by which essential thermal energy unstable condition was provided for the gale and strong sandstorm eruption, the strong sandstorm appeared in downstream of -200 m^2s^(-2) center of vertical helicity, the vertical helicity had good instruction significance for development of squall line and landing region of sandstorm, the mesoscale squall line occurred in unstable stratification, basic condition of potential energy transforming as kinetic energy was provided by strong unstable stratification for the strong sandstorm forming and developing.

结果表明：中尺度飑线所伴随的强风暴是产生强沙尘暴的主要原因；500 hPa阶梯短波槽是中尺度飑线产生的大尺度触发系统，河西走廊中西部700 hp变形场、中尺度低压为强沙尘暴形成和维持提供了必要的动力条件；地面冷锋前上升运动与高空急流入口区次级环流的上升气流的叠加，为深对流发展提供了深厚的垂直环流发展条件，是促使飑线发生和沙尘卷起的基本动力；地面热低压的加强和午后气温的日变化加大了冷锋前后的温度和气压梯度，为大风、强沙尘暴爆发提供了必要的热力不稳定条件；强沙尘暴出现在垂直螺旋度为－200平方公尺/s^2中心的下游，垂直螺旋度对飑线的发展和沙尘暴的落区具有较好的指示意义；中尺度飑线发生在不稳定层结内，较强的不稳定层结为强沙尘暴形成、发展提供了位能转化为动能的基本条件。

Furthermore, its working characteristics are studied experimentally and compared with those excited by the only DC glow discharge. Under the action of transverse silent discharge, the laser power, the gas-filled pressure and the fraction of N2in the laser are increased obviously, the laser efficiency is increased, too.

实验表明，由于横向无声放电的作用使这种激光器的激光功率、工作气压和工作气体中氮的比例有明显的提高，激光效率也有所提高，而且放电电流能兼顾最大激光输出功率和最佳效率。

PCDSG displays basic observational data at Wushan station of Guangzhou,four stations nearly,Qingyuan rawinsonde station and Hengshan station.Time series curves of pressure,temperature,humidity and upper air physical values are also included.PCDSG has been used in routine service and appeared as a valuable tool for short - term weather forcast in Guangzhou.

系统可实时显示广州五山站、四个县级市、清远探空站、衡山站的基本资料，显示气压、温度、湿度等观测要素或清运探空站物理量的时间演变曲线。

At higher altitude the air pressure is lower and the number of oxygen molecules taken in with each breath is reduced.

在高海拔的地方气压较低，平均吸入的氧气量较少。

PRESSURE ALTITUDE, The altitude displayed when the barometric pressure on the altimeter is set to 29.92 inches of mercury.

压力高度，当高度表上的气压调至29.92英寸汞柱时显示的高度。

Air pressure decreases with altitude.

气压随着高度的而下降。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
