解釋
碳源-
The structures and characteristics of several graphite samples are measured by means of powder x - ray diffraction ( xrd ), brunauer - emmer - teller ( bet ) surface area measurement, inductively coupled plasma ( icp ) spectroscopy, particle size analysis and electrochemical measurements. the effects of origin, structure, impurity, particle size, specific surface area of carbon materials on the electrochemical characteristics are studied. a synthetic graphite with abundant resources, low cost and favorable performance is determined as the raw material for modification of graphite
採用xrd 、 bet 、 icp 、激光粒徑分析及電化學性能測試等方法，對國內外多種典型石墨樣品的結構與性能進行比較，研究石墨材料的來源、晶體結構、雜質含量、顆粒大小、比表面積等因素對其充放電性能的影響，確定一種性能較好、價格低廉、來源廣泛的普通人造石墨粉作為熱處理與摻雜改性、以及復合結構炭材料研究的原材料。 -

四種土壤和沉積物有機質中除了腐殖酸和乾酪根，都含有相當數量的碳黑，最少的海洋沉積物有機質中碳黑含量也達到18 . 36 。 -
Then it makes a summary of the terrestrial carbon deposition and points out several potential land - origin carbon traces including dam capture, deposition happening in floodplain, estuary and near - shore area, and terrestrial carbon precipitation
之後對陸地碳沉積機制進行了歸納，指出了包括大壩截留，河漫灘、河口近岸帶沉積及陸地碳沉降等幾種可能的陸源碳蹤跡。 -
And even if it could, it would not really help explain the origin of life, because the time available since the formation of carbon is only just over double the age of the earth
而且即使它能夠，那也不一定對詮釋生命的起源真的有所幫助，因為自碳元素形成以來可用的時間不過是地球年齡的兩倍多一點。 -
