Their emissions are especially damaging , too ? partly because the nitrogen oxides from jet - engine exhausts help create ozone , a potent greenhouse gas , and partly because the pretty trails that aircraft leave behind them help make the clouds that can intensify the greenhouse effect 他们制造出的排放物质对大气层的破坏也尤为严重? ?这一方面是由于喷气式发动机工作产生的氮氧化物会促使臭氧的形成,而臭氧是一种强温室气体;另一方面是飞机掠过后留下的漂亮尾迹会有助于云的形成,从而加强温室效应。
The application of adsorption refrigeration to recovery of engine exhaust heat is attractive and significant to social economy . this dissertation presents a preliminary analysis of adsorption refrigeration for diesel exhaust heat recovery by experimental investigations and numerical simulations . the main works are summarized as following 内燃机余热回收具有重大的社会经济意义,本文将吸附制冷技术应用于内燃机余热回收领域,采用实验研究和数值模拟的方法做了一些探索性的工作,这些工作分为以下几部分: 1
