| At present, natural gas has fird the heating system in some big cities | 现在、有些大城市的供暖系统是天然气烧的 |
| characteristics of combustion and blasting technology in oil-gas wells | 油、气井燃烧爆破技术的特点其特点包括: 1. 要求爆破器材设计制造得非常精细，结构严密,施工技术要求十分严格。 2. 油、气井燃烧爆破在复杂的外界环境中进行，施工要求更加严格。 3. 油、气井燃烧爆破器材要有良好的耐温、耐压性能。 4. 油、气井燃烧爆破器材应具有良好的密封、绝缘性能。 5. 起爆技术、传爆技术要求特殊 |
| classification of combustion and blasting equipment in oil gas wells | 油、气井燃烧爆破器材分类油、气井燃烧器材种类繁多,目前国内使用的油、气井燃烧爆破器材，按使用性能和应用品种可分为三大类: 1. 油、气井用爆破器材, 2. 油、气井用燃烧器材, 3. 起爆、传爆器材 |
| CO₂ emissions from ammonia production are found both in the combustion of a proportion of the gas to provide process heat and from the reforming of the feedstock gas to provide ammonia synthesis gas | 人们发现、氨生产过程中释放的二氧化碳一部分是来自提供热量的气体燃烧、另一部分来自于提供氨合成气所需的原料气的制备过程中 |
| detonating cord used in oil and gas wells | 油气井用导爆索以耐热炸药为药芯、以耐温材料作包覆外壳的耐温、耐压高能导爆索。即用于油气井开采作业的工业导爆索 |
| Gas bubbles generated by entrapment of air or by chemical gassing are compressed by the head of water and /or fluid product loaded in the borehole | 由圈闭空气或由化学充气产生的气泡受到水压头的挤压、而且或受到装进炮孔中的液态炸药的挤压 |
| The gas composition is strongly dependent on many factors such as actual field detonation conditions, rock type,hole diameter,water presence,product homogeneity in the hole | 气体的形成在很大程度上取决于诸多因素、如现场实际爆轰条件、岩石类型、炮孔直径、有没有水以及炸药在炮孔中是否均匀等 |
| When an explosive charge is detonated in rock, the charge is converted instantly to a hot gas at intense pressure | 当药包在岩体中爆炸时、炸药在高压力下瞬间转化为高温气体 |
