蒸汽

The most important character of such a problem is that the vapor makes not only a bulk motion under the pressure gradient with the whole gas phase together, but also a diffusive motion relativing to the incondensable gas.

这类问题的主要特点是蒸汽不仅随着不凝性气体在压力梯度的驱动下做整体运动，还有相对于蒸汽相对于整体运动的扩散运动。

On the basis of same main components, comparison and analysis are performed on thermodynamic performance of HAT cycle, STIG (Steam-Injected Gas Turbine) cycle, gas-steam combined cycle and the relevant cycles with intercooling or reheat.

在主要部件相同的基础上，分析比较了HAT循环、注蒸汽燃气轮机循环、燃气—蒸汽联合循环以及各循环采用中冷或再热手段后相应循环的热力性能，确定了再热HAT循环高效率和中冷再热STIG循环高比功的优势，指出中冷手段对循环性能改善不大，回收中冷热量也不会收到好的效果，而再热手段对循环性能改善显著。

Steam generator level is a non-linear, mutative and multi-variable system. It is a problem to design the control system because of"false level".

蒸汽发生器水位控制系统是非线性、时变的多变量系统，&虚假液位&现象的存在使蒸汽发生器液位控制成为一个难题。

The steam and nitrogen push uses steam as the heat source ,extra heavy oil or bitumen has been mobilized by conductive heating and rely on the action of gravity of condensed liquid to recovery heavy oil. Because nitrogen is noncondensible gas and its density is lower, nitrogen rise and accumulates in the top of the reservoir.

蒸汽―氮气辅助重力泄油的开采机理是以蒸汽作为热源加热油层，使高粘度的原油、沥青获得较好的流动性，利用气体和液体由于密度不同而产生的垂向分异作用，靠油的重力开采。

The Effects of Substrate s Volume and Density on Pleurotus Ostreatus Growth;2. Relation between degree of gelatinization and density of steam-flaked corn was found.

利用自行设计委托加工的蒸汽压片设备，选择不同温度与时间的工艺参数进行玉米糊化度与容重的测定试验，以确定蒸汽压片玉米的最适工艺参数。

Incorporated in the injection train is a pneumatically operated flow control valve, which controls the steam flowrate.

蒸汽 喷射器前有一个气动控制阀，它控制着蒸汽的流量。

Reactor accident and fault analysis ; RELAP 5; main steam line break ; steam generator tube rupture

反应堆事故及其分析； RELAP 5；主蒸汽管道断裂；蒸汽发生器传热管破裂

Three in vitro gas production experiments were conducted using the procedure described by Menke et al.(1979) to investigate the effect of steam conditioning time, processing method and corn variety on the gelatinization of starch and ruminal fermentation characteristics of corn grains.

本文应用人工瘤胃法，进行以下三个试验研究：1 不同调制时间预处理的蒸汽压片高油玉米对淀粉糊化度和人工瘤胃发酵的影响；2 比较最佳调制时间处理的蒸汽压片、微化、膨化及爆破不同方法处理的高油玉米对淀粉糊化度和人工瘤胃发酵的影响；3 不同品种玉米对淀粉糊化度和人工瘤胃发酵的影响。

The steam generator, in the incorporate type of the high-temperature gas-cooled reactor, should be of the compact structure, the least heating surface and the higher power density in order to decrease the volume of the initial-stress concrete pressure vessel, there by the steam generator with the uniflow multi-start helical coiled tubes is used generally for it possessing all these characteristics.
