A research of the cultivation treatments of the commonly used compost fermentations on Volvariella Volvacea production was made in this paper by comparison with the cultivation of raw ingredients. They are zymotechnics of water-logged compost, twice regular zymotechnics and simple twice zymotechnics. The result shows that the cultivation effects of above three are better than that of the cultivation of raw ingredients, among which the simple twice zymotechnics is the best.

By getting Lebesgue characteristic of integrable function of Riemann from the definition of Gather zero measure, discussing the relation between almost continuous everywhere and existent of limit, it gets the theory which is from the function integrability to the consecution and from consecution to the limit existence .i.e. the almost limit existence is equal to the almost continuous everywhere in the integrable function of Riemann. It also gets a unified condition which has a wider range than regulated function and comes to the conclusion that the function of bounded variation is the integrable function of Riemann.
