WebSummary Most of the well-known oil-bearing black shales are united by the fact that they contain abnormally high contents of a number of chemical elements (U, S, Fe, Mg, P, Cu, Zn, Mo, V, Ni, Ba, As, etc.). The study of variations in the content and ratios of these elements makes it possible to obtain an increase in geological data on the genesis and … Web1 dec. 2024 · 化工常用英语词汇化工常用英语词汇BIOX.CN时间:2006-8—24来源:生命经纬jacket夹套ﻫjacketcooling套管冷却jacobcell雅讣电池ﻫjacobsenrearrangement雅可布森重排ﻫjade硬玉ﻫjadeite硬玉jalap贾拉普ﻫjapan黑漆jasminoil茉莉花油jasmone茉莉酮ﻫjasper碧玉javelwaterjawbreaker腭式碎石机ﻫjawcrusher腭式碎石机ﻫjelly凝 …
