Percent of water,temperature and pressure conditions of natural gas hydrate formed in gas pipeline are analyzed.

通过分析输气管道天然气水合物形成的水分、温度和压力条件，给出了输气管道内NGH形成区域的预测方法。

In the process of building up the system, all the following works are done: confirming the index system of the gas pipeline by the maximum quadratic mean deviation analysis, caculating the index weight by the means of AHP, bringing forward three easy and useful methods (TOPSIS, the effect function and the integration index) of the gas pipeline's engineering schemes' multi-valuation and at last the mathematical models of the maximum compatibility degree is introduced to integrate all the results of all methods above.

在构建这个系统的过程中，主要从事了以下一些工作：通过统计理论中的最小均方差法分析确立了输气管道指标体系；采用层次分析法对输气管道指标权重进行了分析计算；提出三种简单易行的用于天然气管道设计方案评价的新方法：理想点法、效用函数法和综合指数法；最后将决策理论中的最大兼容度模型用于输气管设计方案评价中。

但输气管道投产前存在于管道内壁和管道低洼处的液态水对天然气有增湿作用，导致天然气露点在输气管道投产初期不能满足管输要求。

However, the liquid water exists on the inner wall and the pipeline sinkage before the line comes on stream will have a humidification function to the natural gas, because of which the dew point temperature of natural gas can not meet the requirement of gas transmission at the early stage of the pipeline commissioning.

但输气管道投产前存在于管道内壁和管道低洼处的液态水对天然气有增湿作用，导致天然气露点在输气管道投产初期不能满足管输要求。

Boilers operating wjth both forced and ind.uced draft use the forced draft fan to push air through the combustion air supply system into'the.furnace,The fan must have a discharge pressure high enough to equal the total resistance of air ducts,air heater, burners or fuel bed and any other resistance between the fan discharge and the furnace.

锅炉的运行是使用强制通风风机将空气通过空气燃烧供应系统供入炉内。风机必须有足够高的排气压力来平衡输气管、空气加热器、炉膛或燃料箱及输气管到锅炉之间所产生的全部阻力。

At the same time, realize the secure and steady schedule by the rapid reponse to the gas network and optimum control and enhance the capacity of early warning for production and running, rapid response and dealing with the emergency.

同时，通过对输气管网快速响应和优化控制，实现输气管网的安全平稳调度，增强生产运行的预警能力、快速反应能力和应急处理能力，缩短事件应对时间，提高管理水平和效益。

With the coming of peak period of our country's gas pipeline construction, how to use and perfect the Natural Gas Long Transportation Replacement Commissioning Technique to guarantee successful replacement of natural gas transmission line has increasingly become a focused problem.

随着我国输气管线建设高峰期的到来，如何利用和完善&天然气长输管线置换投产技术&保证输气管线顺利投产已成为人们日益关注的问题。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
