1·Amount of methane emission was closely related to the air temperature.
甲烷排放量与气温呈正相关。
2·Methane from rice paddy is one of major contributor to methane emission.
稻田是甲烷的重要排放源之一。
3·In addition, wetland soils are known for methane emission, a greenhouse gas.
此外，湿地散发沼气这种温室气体，是人所共知的。
4·Waste (methane emission) management and construction of energy efficient housing;
废料（甲烷排放）管理和节能房屋的建设；
5·Different cropping systems also resulted in seasonal variations of methane emission.
耕作制也影响稻田甲烷排放的季节变化规律。
6·The methane emission peak of early rice appeared in young panicle differentiation stage of rice.
早稻甲烷排放峰值出现在水稻幼穗分化期，晚稻种稻期间甲烷排放通量在水稻分蘖盛期最大。
7·Methane emission was higher from late rice fields than from early rice fields, in all treatments.
各处理晚稻田甲烷排放总量高于早稻田甲烷排放总量。
8·Research progress in recent years on methane emission from rice fields in China was summarized briefly.
简要综述了我国近年来在稻田甲烷排放研究中取得的进展。
9·The results showed that methane emission had obvious daily and seasonal variation law in rice-duck complex ecosystem.
结果表明：稻鸭复和生态系统中甲烷排放具有明显的日变化规律和季节变化规律。
10·It confirmed that the amount of methanogens was the one of main factors of amount of methane emission in paddy fields.
从而证实了甲烷细菌数量是决定水稻田中甲烷释放量的主要因素之一。
