查询词典 gravity

The separation action of the gas anchor eliminates the effect of the gas on the subsurface pump and improves the efficiency of the pump; the gravity-type anti-gas device carries out gas-fluid separation by gas-fluid separating principle and chimney stack criterion: while the laser slotted screen pipe ensures the OD of sand in the fluid less than 0.05mm.

闭式气锚的分离作用消除了气体对抽油泵的影响，提高了泵效；重力防气装置利用液气分离原理和高烟囱原理进行液气分离，液流回流时间可达10 min，排气最高压差可达0.2 MPa；经激光割缝筛管过滤后的液体含砂粒外径小于0.05 mm。

The total gravity force on the star from the stars enclosed by its circular orbit can be treated as if they are concentrated at the center.

对于一个离中心为 r 的恒星来讲，来自轨道内的恒星的引力与把它们集中在星系中心的一样，来自轨道外的恒星的引力合力为零。

This paper demonstrates three different strategies of point distribution for two-dimensional problem. Points are distributed at gravity point,at circumcircle center and at the edge of Voronoi. The examples using these three methods show that the results are satisfactory. Among the three methods, the last is best in terms of mesh quality.

本文以二维非结构网格生成为例，介绍三种布点策略，即重心布点、外接圆心布点和Voronoi边布点，算例表明三种方法均可生成满意的非结构网格，其中Voronoi边布点方法生成的网格质量更好一些。

Working substance transfers heat with its boiling and condensing and is circumfluent by its own gravity. The loop thermosyphon is simple in structure and easy to make, therefore it becomes one of the most effective way to solve heat dissipation of electronic devices with high heating flux.

回路型重力热管不使用毛细结构，工质沸腾和冷凝传递热量后依靠重力自然回流，结构简单、加工方便，是解决高热流密度电子器件散热的重要手段之一。

You must prevent circumfluenting to the boiler if the boiler closes chake valve. Rail pressure valve and buffer pistons in the act of gravity can realize the pressurize immediately to make the steam and condensate water not to circumfluent to the boiler in low pressure.

如果锅炉没有关闭截止止回阀，则必须防止回流到锅炉上，阀瓣压铁和缓冲活塞，在重力的作用下，能够迅速实现密封，使得蒸汽和冷凝水即使在低压下也不会回流到锅炉里。

If the boiler don't close the check valve, then must prevent back flowing to the boiler, valve clack mould weight and buffering piston can seal under gravity action, they make steam and condensed water can't flow back to the boiler under the low air pressure.

如果锅炉没有关闭截止止回阀，则必须防止回流到锅炉上，阀瓣压铁和缓冲活塞，在重力的作用下，能够迅速实现密封，使得蒸汽和冷凝水即使在低压下也不会回流到锅炉里。

The gravity of Russia's economic crisis had led the official media to clamour for a return to strong leadership.

俄罗斯经济危机的严重性，导致官方媒体重新呼吁强有力的领导。

Using the climatologically mean temperature and salinity from the Levitus data, the solutions with different modes of the gravity waves and planetary waves are analyzed.

利用Levitus气候平均温盐资料，分析了线性理论意义下南海的重力波及行星波的不同模态解，其一阶模的相速度分布与真实地形关系十分密切；通过行星波的临界频率的计算，从理论上描述了南海行星波动的特征。

METHODS: Calvarial osteoblasts of neonate rats were cultured under conditions of normal gravity(1G) and simulated weightlessness induced by clinostat respectively. The total RNA in cells was isolated in different time points (24, 48, 72 h). Reverse transcription PCR analysis was made to examine the gene expression of α5,αv and β1 integrin subunits.

培养的大鼠乳鼠颅骨成骨随机分为对照组和失重组，在实验的24， 48和72 h提取细胞总RNA，进行反转录PCR，检测整合素的α5，αv和β1亚单位mRNA表达，并计算与内参照β肌动蛋白 beta？？？？

The total RNA in cells was isolated in different time points (24, 48, 72 h). Reverse transcription PCR analysis was made to examine the gene expression of α5,αv and β1 integrin subunits. Each value was normalized against that of β actin mRNA.
