Of course, automotive fuel changing from gasoline and diesel into gas fuel is also carried out blazingly everywhere in our country. Because automotive gas-fuel supplying system is yet not self-contained, and now a large of running vehicles by gasoline and diesel are the largest consumers of petroleum and source of pollutants, so vehicles by liquefied fuel being transferred into Gasoline/Gas amphibious-fuel or Diesel-Gas dual-fuel vehicles is the best way of automobile using gas fuel in our country now.

当然，我国各地也兴起了汽车燃料油改气的热潮，由于我国车用气体燃料的供给基础设施建设远未完善，并且目前在用的大量汽、柴油车是我国的石油消耗大户和最重要的污染源之一，所以我国目前最现实的做法是把大量的汽、柴油车改装为气体燃料／汽油两用燃料汽车或气体燃料—柴油双燃料汽车。

After the tested N gas components are led into the spectrograph via sampling probe and pipeline, the spectrograph obtains the transmittivity data in the scanned wave number or wavelength range and transmits the data to the computer, the computer extracts the effective characteristic quantities as the input to the parallel supporting vector machine algorithm module, and the supporting vector machine outputs the multiple component gas concentration values.

提要 用示踪气体浓度衰减法对某会议室的自然通风作了实测研究，分析了影响换气次数的各种因素、示踪气体浓度衰减法的有效性及其正确应用。揭示出不同的房间布置及不同的门窗开启情况对换气次数有很大影响，而示踪气体浓度衰减法是对此进行实验研究的有效手段。

Under middle and high heat flux, the liquid was degassed with the result that the boiling was pure liquid nucleate pool boiling, and, hereafter, the heat transfer coefficients could not be raised with increasing dissolved gas.

实验结果发现，低热通量时，相同热通量下的壁面温度会随著可溶解气体含量的增加而降低，主要原因是增加气体含量可以降低初始沸腾的热通量；中高热通量则因液体中所含的气体被除气所致，为纯液体核沸腾，热传系数无明显的提升。

The main reasons and its correlated factors of the photoacoustic signal had been quantitatively analyzed based on signal absorption and photoacoustic rationale. It is found that the changed coupling coefficient of sound source and optical cavity modes which caused by the intensity of incident light absorbed by gas sample is the major reason, and a criterion was put forward for signal saturation depth estimating.

基于气体吸收和光声光谱原理定量分析了光声信号饱和的主要原因及影响因素，分析表明气体样本对入射光强吸收而导致的声源与本征共振模式的耦合系数改变是异常饱和的主要原因，并导出判定光声信号饱和深度的准则以用于判定高浓度气体饱和深度。

It pumps the same volume of work and the general principles, Shaft is a concerted installed in the pump body in a position eccentric rotor component, Journal of the three rotor blade will pump cavity divided into three studios, since gas was pumped into the suction mouth. break through strainer into the pump room and check valve, rotor, The studio itself complete with suction inlet isolation rooms will pump gas compression and access to the box and exhaust gas emissions.

它的工作原理与一般容积泵相同，是由一个与传动轴同心安装而在泵体内处于偏心位置的转子组成，转子上有三个径向滑动的叶片，将泵腔分隔成三个工作室，被抽气体自吸气口进入，通过打开的逆止阀与过滤网进入泵室，当转子旋转时，完成吸气的工作室自行与进气口隔离并将气体压缩和通过泵室与排气箱之间的通路将气体排出。

In fact,it is function of temperature and pressure especially for HTHP gas well.

以往的模型在确定气体参数时，很多情况下把井筒内的气体黏度认为是不变的，而实际上黏度是温度和压力的函数，尤其是在高压情况下，气体黏度在不同的井段是一个动态变化的量。

There is no iron carbide existing in pellet samples when reaction is used gas containing higher content of CO〓 and H〓O.

该球团在CO〓、水蒸气含量较高的气体中反应时不能得到碳化铁，但适量的CO〓、水蒸气加入到反应气体（尤其是CO含量较高的H〓-CO气体）中时，减少了CO的沉积量，有利于碳化铁的生成。

Sulfur Recovery. The main feed streams to the SRU (Fig. 2) are acid gas from the AGRU regeneration column, which contains all H2S removed from the feed gas and the acid gas from the regeneration-gas treatment unit that contains the mercaptans removed in the MSU.

硫磺回收：输至同步再生机组的主给原料气流（图2）是来自AGRU再生塔的酸性气体，这气体中所含有的硫化氢是从含有硫醇的再生气体解决机组的原料气和酸性气里脱离出来的。

Again, assuming a 1-D flow of a perfect gas, the, gas properties at any nozzle area ratio can be obtained by knowing a property of the gas called the ratio of specific heat capacities, or gamma.

再次，假设一维流动的一个完美的气体，气体性质在任何喷嘴面积比例可以得到知道的一个性质的气体所谓的比例，具体的供热能力，或伽玛项。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
