蒸汽

This makes more and more people pay more attention to studies and applications of numerical simulation in thermal recovery. In this research, we have developed a reliable mathematical model for thermal recovery, which takes a full consideration of the effect of viscos, gravitical and capillary forces on the three-phase flow of gas, water and oil, the effect of the temperature on the medium characteristics of liquid and solid, the phase equilibrium of gas-liquid in each component, heat transportation including connection, conduction and radiation as well as heat losses in both the overburn and underlying strata. In the space discreation of the mathematical model, we have proposed a new method based on the improvement of the conventional nine-points difference approximation, which has a higher difference accurancy.

本项研究以热力采油的主要机理为基础，充分考虑在粘性力、重力和毛管力作用下油水气三相流动，考虑温度对各种流体和固体介质物性的影响，考虑每一组分中汽液两相的相平衡，考虑热在地层中的传导、对流和辐射以及上下盖层的热损失，利用热力学第一定律、质量守恒定律和流体迁移定律，建立了正确可靠的注蒸汽数学模型；在对数学模型进行空间离散时，利用控制有限体积积分法，对以往的九点差分近似作了合理的改进，使其具有较高的差分近似精度：结果表明，该公式的近似精度要比以往文献中所给的九点差分近似精度高，可以认为，在油藏数值模拟中，如果遇到非均质情况，使用这种九点差分近似更合理。

Oil exploitation mining method is facing a great challenge: changing from Steam Air Gorge and Disgorge to a new method, it is a inevitable need for the new dynamic test.

石油开采面临由蒸汽吞吐向新的开采方式转换的巨大挑战，新的动态测试方式是必然需要。

Finally when using steam, it is possible to entirely get rid of any disinfectant or detergent.

最后当使用蒸汽时，他可以彻底的避免使用任何的消毒剂和清洁剂。

He had the manners of a disobliging steamroller (most steamrollers are abjectly obliging and conciliatory); and he was rather less particular about his dress than a scarecrow: in fact he was once arrested as a tramp because the police refused to believe that such a tatterdemalion could be a famous composer, much less a temple of the most turbulent spirit that ever found expression in pure sound.

他有一架不听话的蒸汽轧路机的风度（大多数轧路机还恭顺地听使唤和不那么调皮）；他穿衣服之不讲究甚于田间的稻草人：事实上有一次他竟被当做流浪汉给抓了起来，因为警察不肯相信穿得这样破破烂烂的人竟会是一位大作曲家，更不能相信这副躯体竟能容得下纯音响世界最奔腾澎湃的灵魂。

In this thesis, control and optimization of heat pump assisted distillation is studied based on a mechanism model.

In recent years, with "double at the end of Distiller's Grains Grains heap fermentation and then" Run-expected accumulation of unprocessed high-temperature steam mixed mixed hanging, and so the effectiveness of new technology research and put into use, making the company's products, technical content and quality of another step on a new level.

近年来，以"双在酒糟发酵结束谷物堆，然后"运行预期累积未处理高温蒸汽混合混合吊等新技术研究的成效，并投入使用，使公司的产品，技术含量和对一种新的台阶一步的质量。05.11.15

And the far field divergency angles of the output beams are detected experimentally, the results illustrate that compared to the single UR90, this new coupling technique may nether weaken the mode control ability, nor effect the beam quality.

此外，还利用铜蒸汽激光器实现了两台放大率M=1.21的UR90腔和两台放大率M=1.5的环状输出UR90腔的相干并束输出，并对输出光束的远场方向性进行了测量分析。

Thus vapor doping method is a new and effective method.

因而，蒸汽掺杂是一种新型高效的掺杂方法。

boiler is a important power equipment,the require is to provide qualified vapour,let the amount of vapour maked by boiler suit for the load.because of this,every main parameter in the process of the product should be strict controlled.this paper is introduced same main control system in the process of boiler control、concentrate and disperse control system 、the characteristic and the develop of the MCGS compose status software.integrate with the technique of the boiler, discuss the single momentum, double momentum, three momentum boiler control system distinguishly.we think in the process of micro boiler control, three momentum control is the best choice,and has been well implemented in the water level mediation.further more,use the concentrate and disperse control and MCGS compose statue sofeware can achieve the control of the boiler,and can reach a fine effect..

锅炉是一个重要的动力设备，其要求是供给合格的蒸汽，使锅炉发气量适合负荷的需要。为此，生产过程的各个主要参数必须严格控制。本设计了研究锅炉控制过程的几个主要控制系统，以及集散控制系统和MCGS组态软件的特点和发展状况。结合锅炉的工艺情况，针对单冲量、双冲量、三冲量锅炉控制系统，对它们存在的利弊做出了比较和分析。结合生产实践，对三冲量的算法进行比较，认为在小型锅炉控制过程中，三冲量控制是最好的选择，并在水位调节中得到很好的应用。

Moreover,this potential nonwoven technology is claimed to double bond webs depending on mechanical entanglement and heat-fusible function.
