求翻译：石墨烯SEM圖，由於石墨烯層的數量也決定了不同區域的亮度,由於較低的電子吸收,薄膜越薄，顏色越亮，暗區域可能是由幾個因素的影響，如碳含量或基板結構等因素。是什么意思？

Graphite alkene SEM figure, the graphite alkene-level the number of different regions of the decision brightness, since the lower electronic absorption, thin-film thinner, the colors the bright, dark area may be due to several factors, such as carbon content or board structure.

Graphite alkene SEM chart, because graphite alkene level quantity had also decided different region brightness, as a result of the low electron absorption, the thin film is thinner, the color is brighter, the dark region is possibly by several factor influences, like factors and so on carbon content

Graphene SEM figure, since the number of Graphene layers determines the brightness of different regions, due to lower absorption, film is thinner, the colors brighter and dark areas may be affected by several factors, such as carbon or substrate structure and other factors.
