Different bottlers of fuel propane use different odourants and so do green gas bottlers hence the different smells.

不同的燃料丙烷使用的刺激性气体的添加剂都不同，所以绿气的味道也许是不同的。

The layer, microstructure and thickness could be accurately controlled by adjusting preparation parameter. The ZnO gas sensors with different Al dopping method were measured, and it is indicated that ZnO self-assembled film has better performance than thick film to use as gas sensors.

测试了不同掺Al方式的ZnO气敏元件对多种还原性气体的气敏性能，表明自组装法制备的ZnO薄膜气敏元件比传统的厚膜元件具有更优异的气敏性能。

According to the appearance that the gas in soil can effect the propagate of stress wave, and combine with some test conclusions in three—phase saturated soil under explosion wave, theory of mixture is applied in this paper and the dynamic analysis model and constitutive relation are built.

根据土中气体的存在对应力波的传播有显著影响的现象，以三相饱和土为研究对象，结合三相饱和土在爆炸载荷作用下的有关试验结论，以混合物理论为基础建立动力分析模型和本构关系，在此基础上得到用于三相饱和土的有限元方程，计算结果揭示了动力固结法的若干特点。

The application of the alloy that can effectively reduce the release of hydrogen, the special technique in manufacturing grid, and the appropriate match of active materials of both negative plates and positive plates, all these enable spiral valve-regulated sealed lead-acid battery, greatly restrain the release of hydrogen from negative plates, at the same time the generated oxygen, due to overcharge of positive plates, arrive at negative plates through the diaphragm and compose with lead in the negative, thus enable the recombination of gas inside of the battery and prevent the case of water loss so that water addition is free.

双登卷绕式阀控密封铅酸蓄电池通过采用具有极高析氢过电位的合金通过特殊工艺制造板栅，同时对正负极活性物质量的合理匹配等工艺措施，使得负极上发生的析氢过程得以最大限度地受到抑制，同时正极因过充电所产生的氧气通过隔膜到达负极，并与负极上的铅发生反应，生成水，这样便使得电池内部气体的再复合，防止失水，实现免维护。

The outgas types and amount of different gas resource varied with the different geological conditions and evolution processes. There are four outgas models including the model in which inorganic gas directly overflows from mantle matter through lithospheric fracture,the model of heat flow piercement outgas,the model of volcano-magma outgas,and the model of carbonate rock outgas due to heat metamorphism.

对气藏成藏条件和深部壳幔结构的研究表明，松辽盆地存在多种类型无机&气源&，由于赋存的地质条件和演化过程不同，不同气源脱气的方式、脱出气体的类型、脱气量也大不相同，共有4种主要的模式：地幔物质沿超岩石圈断裂直接脱气模式；热流底辟体脱气模式；火山—岩浆成因模式；碳酸盐岩热变质成因模式。
