In most planes , the engine turbines are visible through the air inlet -- and they 're a huge source of radar reflectivity .
大多数飞机发动机涡轮时能通过入风口看到的,这也就成了雷达反射率高的很大来源。
This would create lighter , whiter clouds to increase the reflectivity of the earth and deflect more sunlight into space .
这将生成更轻更白的云团,从而提高地球的反射率,将更多阳光反射到太空中。
In both cases , the carbon surfaces made the objects good absorbers of light , having extremely low reflectivity .
在两次演示中,碳表面都让物体具有了良好的吸收光线的能力,反射率极低。
Any mechanicalness or reflectivity or infected cause can destroy the nasal function to sustain normal ventilation , and then cause the obsruction of nasal cavity .
任何机械性、反射性、感染性的原因都可能破坏鼻腔的通气功能,而引起鼻阻塞。
Combined with their reflectivity measurements , they calculated that ships decrease the amount of solar energy absorbed by the oceans by 0.14 milliwatts per square metre ( geophysical research letters , doi : 10.1029 / 2011gl048819 ) .
