△C理论认为,只有油气成因的蚀变碳酸盐在500～600℃温度下产生热分解.作者通过实验认为,其它成因的次生碳酸盐也可在500～600℃下大量分解.换句话说,这些次生的非晶质的碳酸盐(包括△C)可能是该温区分解的主要物质.鉴此,作者根据它们之间函数关系,对其测值进行修正.

With △C theory,it is believed that a pyrolysis will take place only in the altered carbonate of hydrocarbon generation under the temperature range of 500~600℃.However,through the experiments,the author concludes that much pyrolyses will occur in the secondary carbonates of other origins at the temperatures of 500~600℃.It means that these secondary noncrystalline carbonates( including △C)are the major pyrolytic products within the temperature range.In view of this,the author modifies their measurements based on the functional relationships between the carbonates.
