The experiment data proved that this kind of reaction was kinetically controlled and the internal diffusion limitation can be neglected. 提出了攪拌釜中克服外擴散的方法和條件，實(shí)驗證明了反應過(guò)程為動(dòng)力學(xué)控制，內擴散影響可以忽略。
The aggregation and diffusion of indus tries and the evolution and promotion of industrial structure are important fact ors to maintain TEB and motivate its development. 然后沿著(zhù)交通線(xiàn)逐步向外擴散，在有利的地點(diǎn)形成新的生長(cháng)點(diǎn)。
