摘要
The article adopted the orthogonal experiment investigating four factors: temperature of reaction; density of phosphoric acid; content of sulphur; content of fluoride, discussed the effect of the four factors to qualities of Urea phosphate, and applied regression analysis establishing five models of mathematics: equation of production; equation of phosphorus’s content; equation of sulphur’s content; equation of fluoride’s content and equation of nitrogen’s content.In addition,the step of crystallization was discussed on the aspect of engineering.
