This paper focuses on the effect of different temperature on methane capacity and CO2 reduction potential of the anaerobic fermentation.Four anaerobic digesters of 10L capacity have been operated in batch mode at temperature of 19℃, 30℃, 37℃and 52℃, respectively.We can know how the temperature influences the potential of producing methane with anaerobic fermentation of cattle manure.And the result shows when the temperature was 37℃, the fermentation cycle was 22 days, the volumetric biogas production rate was 0.76 m3/m3·d, the biogas production yield was 0.31m3/kg TS, and the average content of methane was 53.59%.Taking methane produced by household biogas digesters of Gansu province into account, the annual emission reduction of carbon dioxide was 2.35× 107t.Thus, it shows that we could using anaerobic treatment with cattle manure at 37℃ for biogas production—the potential of higher productivity of methane and lower productivity of carbon dioxide—to replace the traditional energy supply.And it will have good values of application and promotion in countryside.

摘要：小学阶段的学习是为未来的学习奠定根基，数学更是渗透在我们生活的方方面面。近几年，随着教育体制的不断改革与深入发展，国家对数学教育研究的投入也越来越大。小学数学的探究式教学却寥寥无几，实际教学中对于小学数学探究式教学的研究也不够深入，殊不知孩子们的根基没有打稳，怎能健步如飞。所以我们要加强对小学数学探究式教学的实践研究，在平时的教学中，培养学生的创新能力，让学生自主的学习，变被动为主动，通过正
