查询词典 air gas

The results showed that the performance of unchoked ducted rocket is superior to that of choked one. When the gas generator is loaded with high burning-rate exponent fuel-rich propellant, the performance of unchoked ducted rocket is almost the same as that of the ducted rocket working under fixed mass ratio of fuel to air.

研究结果表明：非壅塞固体火箭冲压发动机的性能显著优于燃气流量不可调的壅塞式固体火箭冲压发动机；当贫氧推进剂具有高的燃速压强指数时，非壅塞固体火箭冲压发动机的性能接近燃气流量完全调节、以等空燃比工作的冲压发动机性能。

The unirradiated and irradiated samples are analyzed by FTIR, SEM, PGC/MS and TG. At the same time, the gas products after irradiation are analyzed by GC/MS. The relationship of gel fraction of irradiated samples in air with the dose and the compression property and stress relaxation ratio along with the dose are determined.

采用傅立叶红外分析仪、扫描电镜、裂解色谱质谱联用仪以及热失重分析仪等对辐照前后的样品进行了分析，同时使用色质联用仪对辐照后产生的气体进行了分析，并且测定了空气中辐照试样的凝胶含量与吸收剂量的关系以及在室温下试样的压缩性能、应力松弛率与吸收剂量的关系。

Natural gas is also a fuel; it will burn in air.

天然气也是一种燃料，它可以在空气中燃烧。

The experiment can be optimized by these results: the pellets with great density or with big diameter have the same influence tendency.When the material density is great,the pellet diameter should be taken short relatively,when the material density is small,the pellet diameter should be taken long relatively,the modification effect is best.If spray gas is air,the best pellet diameter should be taken between 1 μm and 10 μm.

结果表明：大密度颗粒与大直径颗粒受流场影响趋势相同；材料密度较大时，颗粒直径应相对取小，材料密度较小时，颗粒直径应相对取大些，喷涂效果最佳；若喷涂气体为空气时，最佳颗粒直径应在1～10 μm。

Common saying says:" Word bright gas comes loose ", only much lay one's heart bare aerates, ability clear the air, promotional understanding, dissolve contradiction, achieve the goal with unified solidarity thereby.

俗话说：&话明气散&，只有多交心通气，才能消除误会，增进了解，化解矛盾，从而达到团结统一的目的。

"Warriv's advice is like corpse gas; it befouls the air for a moment and then it disappears."

瓦瑞夫的建议和尸气一样；它会在空气中放出臭气，然后就消失无踪。

For the coked 5A molecular sieve, using air as regeneration gas at a space velocity of 720h-1, a regeneration temperature of 350℃ and a regeneration time of 1h, the activity of the regenerated molecular sieve could reach 96% of that of the fresh one.

对于结焦5A分子筛，以空气为再生气体，在空速为720h-1、350℃条件下再生1h的吸附活性可以达到新鲜5A分子筛的96%左右。

The gas from factory often contaminates our air.

从工厂排出来的废气经常污染空气。

Under this condition, the preventive measure was increasing the porosity of coal mass and deceasing the circulating channels of gas and air.

提出了增加卸载区的范围，促使煤体裂纹稳定扩展，降低单位煤体储能从而控制冲击矿压发生的原理。
