Physical and chemical properties of crude oil itself, which have an important effect on biodegradation, such as conglutination, boiling point, refractive index, ingredient and concentration of the oil; 石油物质本身物理化学特性的影响,如石油物质在水体或土壤中的浓度以及石油的粘度、沸点、折射率等特性;
And the product has been analysed by mass spectrum and element analysis, and its physical constants, such as boiling point, refractive index and density, have been determined. 通过质量和元素分析手段对产物进行了初步分析,测定了其沸点、折射率和密度等物理常数,并通过了评香鉴定。
