It includes the function of vacuometer , atmospheric pressure altimeter, thermometer and pressuremeter (for example the standard pressure meter of sphygmomanometer calibration).

介绍一种便携、数字式的多用途仪器，它具有真空度计、气压高度计、温度计以及压力计（例如可作为校准血压计的标准器）等功能。

The other one retrieves vertical velocity from the reflectivity using statistical algorithm and assimilates the vertical velocity taking Richardson's equation as observational operator. It is found that the vertical velo city derived by the former is usually too weak while the later gets the distinct three dimensional convective structure of meso-scale system with strong vertical velocity.

其一是采用Richardson方程通过水平风场、温度和气压来对垂直速度进行诊断，其二是利用统计方法由观测的反射率因子反演出垂直速度后，再采用Richardson方程作为观测算子对反演的垂直速度进行同化。

If it falls too low , he may not have enough to get back to the surface , which is why scuba is such a deadly sport for illiterates and hotheads .1qr2MLa ym X0

如果气压降得太低，他就没有足够的氧气回到水面，这就是为什么潜水对于新手和脾气暴躁的人是一种致命运动的原因。

It is understood that the figures Dropsonde main role is to probe the ground to the atmosphere between the 30,000 meters at high temperature, humidity, air pressure and wind direction, the sonde launched about 15 minutes to 20 minutes after the will the completion of its mission blasting ground, because of its small size, light weight, so passers-by will not be injured.

据了解，数字式探空仪的主要作用是探测地面至三万米高空之间大气层的温度、湿度、气压和风向，升空后的探空仪大概在十五分钟到二十分钟之后就会完成它的使命爆破落地，由于其体积小、重量轻，因此不会砸伤路人。

This paper expatiate the study on nail-shotting gun examination system, and applying that equipment to shotcrete strength examination in tunnel. That examinaton method is a better undamage examination method.

本文研究气压射钉枪检测系统，并将其应用于隧道喷混凝土强度检测，是一种比较理想的无损检测方法。

With the development of information-construction, More and more quick, abundant, reliable, undamage examination method to concrete strength are needed. The traditonal examination method to concrete strength can not satisfy the examination request. Study on nail-shotting gun examination system for shotcrete strength is very important for either theory or practice.

随着信息化施工的发展，对快速、大量、可靠、无损检测混凝土强度的技术要求越来越高，传统的强度检测方法难以满足要求，研究喷混凝土强度气压射钉枪检测系统具有重要的理论和实际意义。

Methods MRI and CT imaging of brain were examined and analysed on 5 cases of pulmonary barotrauma complicated with cerebral arterial gas embolism .

方法对 5例空气潜水所致肺气压伤并发脑动脉气栓症患者进行了脑部MRI检查或脑部CT检查，分析脑动脉气栓所致脑影像学的变化。

Speckled Trout are very temperamental fish and are very sensitive to changes in water temperature as well as barometric pressure.

斑点鳟鱼和气质都很敏感水温变化以及气压。

The amount of air pressure required to close the valve depends upon the line pressure of pipeline.

关闭阀门所要求的气压值依赖于管道内的管道压力。

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。
