It was found that the oxygen concentration on carbon black surface is proportional to the ozone supplied per unit area of carbon black surface.

The black material is considered as carbon deposition, which is formed by oily-liquid medium fission product (mainly carbon black) covering inside crack during the discharge process of pulse current.

认为这些黑色覆盖物为脉冲电流在放电过程中，油性液体介质裂变产物(主要为碳黑)涂覆在裂纹内部形成的积碳。

"When we compare changes in the black carbon to changes in these other indicators, it is clear that most of the increases in black carbon in the late 19th and early 20th centuries, particularly in winter and spring, resulted from industrial emissions - probably from coal burning, " he added.

If carbon dioxide were black, we could actually see our atmosphere darkening with carbon dioxide, creating a heat-trapping blanket that is raising global air and ocean temperatures and threatening to dramatically rearrange our climate.

Lehmann, the lead author of the paper which is published in the journal Nature Geosciences, said that the black carbon content of soils in the study ranged from zero to 82 percent of soil organic carbon.
