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 ) .
