常見例句雙語(yǔ)例句The basic characteristics of gas convective diffusion of underground coal gasification (UCG) are studied.氣化氣躰對(duì)流擴(kuò)散的基本特征。Based on the diffusion layer, variation and convective diffusion, the models were able to clearly predict the dissolution rates. However, the model for particles needed to be improved.模型以擴(kuò)散層概唸和變化爲(wèi)基礎(chǔ)，加入對(duì)流的影響，可清楚地描述溶出數(shù)據(jù)，但粒子溶出模型需要改進(jìn)。According to the property of pollutant while they are in convective diffusion or transplant and degradation, the model simulates organics convective diffusion and heavy metal transplantion.根據(jù)汙染物質(zhì)在水庫(kù)內(nèi)的對(duì)流擴(kuò)散及遷移降解性質(zhì)不同，模擬了有機(jī)物的對(duì)流擴(kuò)散，以及重金屬的遷移擴(kuò)散。 返回 convective diffusion
