The side - jet - engine can be used as an implement to control the hvp 對于這種高超速射彈,側噴發(fā)動機控制是一種有效控制手段。
The harm could be amplified by the effects of other emissions from jet - engines at high altitude 噴氣式引擎在高空中排放出的其它物質可能加劇這種危害。
The airline industry has promised great strides in jet - engine efficiency to mitigate the environmental damage caused by flying 航空業(yè)已經在其噴氣發(fā)動機的效率方面做出了很大的改進措施,旨在減少飛機在飛行過程中對環(huán)境造成的破壞。
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 他們制造出的排放物質對大氣層的破壞也尤為嚴重? ?這一方面是由于噴氣式發(fā)動機工作產生的氮氧化物會促使臭氧的形成,而臭氧是一種強溫室氣體;另一方面是飛機掠過后留下的漂亮尾跡會有助于云的形成,從而加強溫室效應。
