The reaction kinetics of the sorbent with so2 was well described by the surface coverage model, which assumes that the sulfation rate is controlled by the chemical reaction on the sorbent grain surface and takes into account the surface covered by the product 吸收剂与二氧化硫的反应可用表面覆盖模式很好地描述;该模式假设吸收剂晶粒表面之化学反应为速率控制步骤,并且考量被产物覆盖的表面积。
In tradition, building spatial database always choose coverage model, which has some shortages such as it has not special character about the expression of spatial object . with the development of oriented-object technology . geodatabase has appeared representing oriented-object spatial model and stride forward to the objected spatial model 传统上建立空间数据库在空间数据模型上一般选择coverage数据模型,这种数据模型在空间对象的表达上存在特征聚集在类似的点、线、面集合中,不具有特殊的特征行为等种种不足。
