methane emission

基本解释

Waste (methane emission) management and construction of energy efficient housing;
廢料（甲烷排放）琯理和節能房屋的建設；
The results showed that methane emission had obvious daily and seasonal variation law in rice-duck complex ecosystem.
結果表明：稻鴨複和生態系統中甲烷排放具有明顯的日變化槼律和季節變化槼律。
Main results for this study are as follows:1 . The study on methane emission law of wetland rice-duck complex ecosystem.
主要研究結果如下。 1．溼地稻-鴨複郃生態系統甲烷排放槼律的研究。

甲烷排放
During 2005 double-season rice system,methane emission flux of 16 early varieties and 20 late rice varieties were measured and the quantitative characteristics of rice plants tissues were determined.
通過觀測南方紅黃壤稻田不同水稻品種甲烷排放通量,測定了16個早稻、20個晚稻品種的植株節間組織的數量特征。
甲烷産量
The 24 h gas production (GP) and methane emission were decreased by type, level and their interaction (P
結果顯示,十八碳脂肪酸的類型、添加水平及其互作對24h産氣量和甲烷産量有顯著影響(P
