With similar geology factors of controlling gas, the content of coalbed methane is controlled by effective stage ofgas genetation and the rateofgasgeneration in this stage.
在其它控气地质因素相似的前提下，有效生气阶段和有效阶段生气率控制着煤层含气量的高低。

Furthermore, the data ofgas production and generationrate were acquired through experiment and landfill gas models fit for domestic MSW were advanced in this paper.
并通过实验室的现场实验，得到了垃圾产气量和产气速率的数据，建立了适合我国垃圾自身特点的产气模型。

On the basis of analysing element data of coal and various macerals, a new computing method for determining apparent coal gasgenerationrateof coal and macerals is proposed out in this paper.
