摘　　要：根据化学反应动力学原理 ,建立了尿素氨化速度的评价方法 ,确定了尿素氨化反应的级数 ,测定了普通尿素、缓释尿素在特定条件下的氨化反应常数和半衰期 ,并依此评价了涂层缓释尿素的缓释性能。In accordance with the principle of chemical dynamics, a new evaluation method for rate of ammonification of urea was established, and the type of reaction of ammonification of urea was confirmed. The half life and constant of ammonification rate of urea were determined, simultaneously, the slow release performance of coated urea was evaluated.
