【Abstract】 Vitrainrflectivity （R₀） has become a very important index in the studyof the maturity of s?urcesource rock and the palaeo- tem-perature of thegeological. formation The conven tional method to measure the reflectivity known as deflection method of current meter, which has been used inthe geological laboratory for many years, has reletively low precisionbecause of the reading method. Also, it is difficult for the personnel tooperate the equipment. The develoment of the vitrain reflectivity photo-digital meter has made marked improvement to insure the measuringprecision as well as the safely operation. It also has the features of easoperating and direct reading of the measured. values. The develop-ment ofthis unit offers much convenience for the future research work both insideand outside of the institute.更多还原
