The linked -OH and aromatic ring showed synergistic reaction and enhanced their interaction.

磷酰化肽酯及小肽的体积大小、空间位阻对相互作用亦有显著影响。

Currently as China's accelerating development of agricultural industrialization and the increase of the agricultural production investment, the demand for chemical fertilizers increases year after year. Simultaneously as China's scientification in fertilization and fertilization ratio of the nitrogen, phosphorus, and potassium fertilizer tending to be reasonable, the chemical fertilizer demand structure will possibly change, the chemical fertilizer market environment will also change, the chemical fertilizer industry will run to the direction of high efficiency and environmentally no harm. Comparing to ordinary urea, large urea has many merits. These merits include big rime, glabrous pellet, smooth and well-mixed, not easy to crush or agglomerate in moist environment, suitable for long distance bulk transport and storage, and so on.

目前随着我国农业产业化的不断加快发展和对农业生产投入的增加，化肥的需求量在逐年上升，同时随着我国农业施肥的科学化，氮、磷、钾肥的施用比例趋向合理，化肥需求结构可能发生变化，化肥市场环境也会发生变化，需求旺盛的化肥业将向高效、环保等方面转化；大颗粒尿素与普通尿素相比，具有结晶大、颗粒光洁、圆滑、均匀，不易粉碎和吸潮结块，具有适合长途散装运输和存贮等优点。
