天然气

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。

In November alone, mining and quarrying activity fell although oil and gas production rose.

在11月份，采矿和采石活动下降，虽然石油和天然气生产上升了。

A combined power cycle with LNG cold energy recovery consisting of Rankine cycle using ammonia-water as working fluid, power cycle of combustion gas, and LNG cycle, was presented.

提出了以氨水为工质的朗肯循环、燃气动力循环和液化天然气循环组成的混合动力循环系统，用于液化天然气冷能回收。

The energy balance equations and exergy balance equations of heat exchanger and power equipment in the combined power cycle were established.Taking condensation temperature of Rankine cycle, inlet and outlet pressure of turbine of Rankine cycle, inlet and outlet pressures of turbine of LNG cycle as key parameters, the influences of these parameters on the thermal efficiency and exergy efficiency of the combined power cycle were analyzed.

建立了混合动力循环中换热和动力设备的能量平衡方程和可用能平衡方程，并以朗肯循环冷凝温度、朗肯循环透平进出口压力、液化天然气循环透平进出口压力为关键参数，分析了上述关键参数对混合动力循环热效率和可用能效率的影响。

Oil, of course, but natural gas or rare earth metals could also be part of this conflict.

石油，当然，但天然气或稀土金属也成为这一冲突的一部分。

So here, retained the original real estate development and gas and days of Aura, as well as natural and as, therefore, here the building of a noble cultural communities has become an ideal place.

所以在这里，保留了原来的房地产开发和天然气和天的光环，以及自然和作为，因此，在这里建设一个高尚文化社区已成为一个理想场所。

If we did leak a little method to a number of "up" gas, real estate, the balloon would not have exploded, not be effective to suppress the market demand, should be an option.

如果我们没有泄露一点的方法了一些"上升"的天然气，房地产，气球不会爆炸，不能有效地抑制市场需求，应该是一种选择。

At present, China has been in Guangdong, Shenzhen, Putian, Fujian, and Shanghai set up LNG receiving terminal project.

目前我国已在广东深圳、福建莆田和上海建立了液化天然气接受终端项目。

The function can be used to calculate gas volume produced from gas hydrate wells and to evaluate the recoverability of gas hydrate reservoirs.

该函数可以用于天然气水合物井气体开采量的计算及对水合物储层可开采性评价。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
