Picture thousands of drones disseminating a killer virus with aerosols " to every nook and cranny " of the planet at once , she said .
她说道,想象成千上万的无人驾驶机迅速通过喷雾剂“向每一个角落和缝隙”散布致命病毒。
Since most aerosols are concentrated near earth 's surface , the aureole at sea level appears much larger than it would high on a mountain peak .
因为绝大多数气溶胶集中在地球表面附近,所以海平面处看到的光晕比高山顶上看到的要大得多。
Taking aerosols into account , climate models do a pretty good job of emulating the climate trends of the 20th century .
把气溶胶(的因素)纳入系统,气候模型都能够很好地模拟出20世纪的气候发展趋势。
Most infrared wavelengths outbound from earth wouldn 't be strongly scattered by aerosols this size , so the particles wouldn 't effectively trap heat in the atmosphere .
The science may have matured , but the role that black carbon and other aerosols play in the changing climate is still rife with nuance , uncertainty and doubt .
科学或许已经成熟,但黑碳和其他气溶胶对改变气候所起的作用还存在细微的差别,不确定性和各种怀疑。
Some of these fine particles -- suspended in air as primary organic aerosols -- are tiny flecks rich in carbon , often from sources such as diesel exhaust .
Sulphur is very good at forming reflecting aerosols that can also make natural clouds both whiter and possibly longer-lasting , which provides an added cooling effect .
Of the first variety , injecting sunlight-reflecting sulphate aerosols into the upper atmosphere is a relatively cheap , easy and quick option .
对于第一种方式,在上层大气注入阳光反射硫盐酸气溶胶是一个相对便宜、简单、快捷的选择。
Secondary aerosols begin life as gases and chemically react in the atmosphere to form particles .
二次气溶胶起初表现为各种气体,在大气中发生化学反应后形成颗粒。
For example , emitting aerosols at rates of 30 micrograms per meter-squared yielded temperature decreases of roughly 7 degrees celsius during the hottest part of the day .
