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。
Based on the principle of chemical reaction kinetics, a method for evaluating the rate of urea amination was established, and the series of urea amination reaction were determined. Ammonia reaction constants and half-lives of common urea and slow-release urea under specific conditions were determined. The sustained-release properties of coated sustained-release urea were evaluated.
