His plane flew through a low pressure area and began to ice up. 他的飞机飞进低压区开始结冰。
Construction Ventilation Technology for Tunnels in High Altitude and Low Atmospheric Pressure Area 高海拔低气压地区隧道施工通风技术
Its energy-saving benefits depend on the way in which the low pressure economizer is connected into the cycle and on the chosen heating surface area and corrosion fatigue life of the low pressure economizer. 低压省烟器系统的节能效益和技术经济指标与低压省煤器的受热面面积及其耐烟气侧低温腐蚀寿命的选择以及与热力系统的联接方式有关。
The mesoscale torrential rain cloud cluster from the low pressure periphery area of the Typhoon No. 9608 9608号台风低压外围暴雨中尺度云团的发生发展
When the coal bed flows from high pressure area to low pressure area, the enriched zone of coal bed becomes the concentrating center of gas and stress. 在煤层由高压区流向低压区后,煤层富集带就成为瓦斯、应力的高度集中点,最易诱发瓦斯突出。
The importance of oxygen in the life activity of the biological organism is self-evident. The low pressure and partial pressure of the hypoxia of the high altitude area are main ecological factors. There are great influences on local animals, plants and human being survival and development. 氧在生物有机体的生命活动中的重要性不言而喻,高海拔地区的低气压与低氧分压是主要的生态因子,对本地动植物和人类的生存与发展有极大影响。
The application of low pressure plastic pipe in shallow burial conveyance of water irrigation engineering in serere cold area 寒区低压塑料管道在浅埋输水灌溉工程中的应用
The paper summaries the parameter determination, pipe network layout, pipe material and auxiliary equipment selection for planning and design of low pressure water delivery pipe system in irrigation area. 该文针对灌区低压管道输水系统规划设计参数确定、管网布置、管材选择、附属设备选择等方面进行了概述。
Research on field water saving technology of low pressure pipeline irrigation on well water irrigated area of the northern plain of Huaihe River 淮北井灌区低压管灌田间节水技术措施研究
The vented gas mixture jetted out under expansion for its higher pressure relative to ambient pressure, and the low pressure area near the exit was formed due to the rarefaction waves of the Prandtl-Meyer flow. 管口附近形成Prandtl&Meyer流稀释波低压区,而稀释波又在射流边界上反射并在轴线附近汇聚,形成压力相对较高的高压区,即悬吊激波高压区。
The low pressure system is supported by positive center of vorticity, the minus vorticity area around it and strong gradient zone between both. 低值系统有正涡度中心支持,外围是负涡度区,其间有强涡度梯度带;
The ECRCVD system has many advantages in respect of low operating pressure, low substrate temperature and large depositing area. 所采用的ECRCVD设备,具有低压沉积、大面积均匀和低温生长的优点。
There exist low velocity, low TSS and low pressure in the flow separation area downstream of tubal stenosis. 圆管狭窄下游流动分离区边壁局部存在明显的低速度、低压力和低切应力分布。
The section steady distortion pressure distribution can be divided into high pressure area, mixing pressure area and low pressure area, each has its own characteristic in distortion and their boundaries are obvious. 截面稳态畸变压力分布可以分成高压区、掺混区、低压区,且分布各有特点,边界明显。
Secondly, the path of hydrocarbon migration is always along the least resisted one; namely migration from high pressure area to low pressure area, and finally accumulate to form reservoir: in the low pressure traps. 其次,油气在地下运移的路线是沿着阻力最小的途径,即从高压区向低压区流动,并在低压的圈闭中聚集成藏的。
The occurrence of the combustible cloud, low pressure area of the rarefaction waves and high pressure area of suspended shock were the basic characteristics in the external flow field before the flame spouted out. 这样,在火焰泄出前,外流场存在可燃云团、稀释波低压区和悬吊激波高压区,这些特征构成外流场的基本特征。
This article is aimed at researching low pressure complex caving ground in Jilin area, studied mechanism of formation instability, analyzed through X-ray diffraction mineralogical analysis and SEM imagery structural analysis. 本论文针对吉林油田低压复杂易坍塌地层,对地层的失稳机理进行研究,通过X&射线衍射矿物分析,扫描电镜成像结构分析等实验对易坍塌地层进行分析。
