Two new maturity parameters, 4-MAD/3-MAD and 4, 9-DAD/3, 4-DAD, have been chosen on the basis of the experimental simulation and proved to be effective in the preliminary research on the 52 samples of crude oil from the Tarim basin.

• 通过热模拟实验还选出了4－MAD/3－MAD和4，9－DAD/3，4－DAD两个新参数。 用52个塔里木原油样品试用，结果表明它们基本上有效。
