The methane emission from soil to the atmosphere is mostly through rice plants, only small amounts of methane is released across the water-air interface via bobbles or moleculardiffusion.
后者主要是通过水稻植株向大气释放,只有少量通过气泡或分子扩散从水田土壤通过田面水层向大气排放。

The experimental data fit well with that from three-compartment model analysis, it suggests that the fluorescence probe labelling process is mainly controlled by moleculardiffusion.
实验结果和用三房空模型分析所得的理论值符合较好,提示荧光探剂的标记过程主要受分子扩散所控制。

Based on moleculardiffusion model of water vapor a theoretical model of frost growth is established and an experimental set with a liquid nitrogen cooled tube is built up.
