气体处理

This paper introduced the use of differential pressure meters which use a double cone as the primary differential pressure producer.

美国的煤层气生产者在煤层气计量方面面临的挑战主要包括：在煤层气井口进行准确的气体流量测量的同时，在测量系统的两端要保持一个低的差压值；要妥善处理流量计测量管段中的湿气体问题等。

The excrescence during the helium replacement in satellite gas store case was tested and analyzed by using gas chromatography of GOW-MAC and Agilent company.

用美国GOW-MAC公司的气相色谱仪和Agilent公司的气相色谱仪对某卫星气体贮箱在氦气置换化验过程中发现的未知杂质进行试验分析，经分析未知杂质的来源可能是所用气体贮箱处理时的残留物。

The distributed optical fiber sensing gas system uses space division multiplexing technology and many gas absorption optical fiber sensors to deal with the gas signals by the harmonic detecting technology.

分布式光纤传感瓦斯气体系统是利用空分复用技术，采用多个气体吸收型光纤传感器，并通过谐波检测技术对瓦斯信号进行处理。

Based on the Percolation theory and the Voronoi model, the pore size distribution is with normal distribution. Considering the flection of the pore, the variability of the pore size and the diffusion of the reactive gas, the comprehensive desulfurization model between CaO and SO〓 is established by adopting the elemental sphere disposal method.

根据由逾渗理论结合Voronoi模型得出的CaO孔径分布符合正态分布的结论，采用微元球壳的处理方法，考虑孔隙长度的曲折性和反应过程中孔径的变化过程和反应气体的扩散过程，建立了CaO颗粒与SO〓气体之间的综合脱硫反应模型。

The cold-shock treatment with ozonated water (ozone concentration 2 mg/L, dipping 5 min in the 1 ± 1 ℃cold water) reduced quantities of bacteria and funguses of winter-jujube, and decreased the rate of loss weight, and extended shelf-life of the fruit. By the ultrastructures of winter-jujube pericarp, cold-shock treatment with ozonated water could clean out the waxiness of crackle and lenticel, which is helpful for exchange of fruit internal CO2 and air, and inhibit accumulating of ethanol concentration.

臭氧水冷激处理(臭氧浓度为2mg/L，浸泡时间5min，水温1±1℃)可以明显降低冬枣表面细菌和真菌的数量，减少失重率，延缓冬枣硬度的下降，提高冬枣的货架期；从微观结构观察发现，臭氧水冷激处理可以清洗冬枣表皮裂缝和皮孔的蜡质，有助于枣果内部CO_2气体的排逸，从而延缓了冬枣的酒化；此外，冷激处理可以明显降低冬枣表面残留的农药：如马拉硫磷、氯氰菊酯和溴氰菊酯农药的含量，提高枣果的食用安全性。

It can be widely used to get rid of toluene,dimethylbenzene,and hydroxybenzene,and ester,and hydroxyketone,and aldehyde as well as bad smell and other gases containing small heavy metal.

可广泛用于处理含有甲苯、二甲苯、苯等苯类、酚类、酯类、醇类、醛类等达式有机气体及恶臭气体和含有微量重金属的低浓度、大风量的各类气体。

Results of edaphon diversity by DGGE analysis of soil DNA showed that both bacteria and fungi Shannon index of treatment N_U were lower than those of treatment No, which suggested that planting crop decreased the soil microbial Shannon index.

油菜地各处理的土壤N_2O、CO_2排放通量高于小麦地相应处理，常规处理和无氮处理的土壤N_2O、CO_2排放通量高于空闲地处理，说明作物的生长促进了土壤温室气体的排放。

And Toona sinensis were steam-treated at temperature 70℃ and 90℃ for 4 h and 8 h. The radial gas permeability and tangential gas permeability of the steam-treated specimens were compared with those of non-steam-treated one.

处理条件为：杉木和马尾松木材的汽蒸温度分别为90、100℃，假水青冈和香椿木材的汽蒸温度分别为70、90℃，处理时间分别为4 h和8 h，并对汽蒸处理前后木材的弦向和径向气体渗透性分别进行了测定。

It produces the gas with low content of tar and ash.

对于木片、木块和秸秆等农林加工剩余物，其含水率不超过25％的，均可使用下吸式气化炉，其气体焦油含量低，含灰份少，对气化炉产生的气体，直接用含镍催化剂处理，发现能提高气体热值，最高可达7230KJ/NM〓。

The results showed that the data of permeability were improved dramatically. Higher temperature could obviously promote the permeability of wood. The effects of steam-treated time on the permeability was slightly different.

结果表明：汽蒸处理后木材的径向和弦向、心材和边材的渗透性都有不同程度的提高，随着汽蒸处理温度的提高木材气体渗透性有较大提高，汽蒸处理时间对不同木材渗透性的影响有所不同。
