The Process and Application of Basified and Ammoniated Straw Grain Fodder 碱化和氨化麦秸尿素颗粒料的加工及其应用
Effect of Gypsum on Improving Basified Soil(ⅱ)& Columns of mixture of gypsum with soil from top 20 cm 石膏改良碱化土壤的效果(Ⅱ)&石膏与土上部20cm混匀的土柱系列
To study the effect of gypsum on improving basified siol, columns of mixture that made by gypsum and soil from top 20 cm were used. 利用石膏与上部20cm土混匀制成不同深度的土柱,分析了石膏改良碱化土壤的效果。结果表明各处理的改良效果特点是自上而下逐步脱碱。
It used soil column modeling gypsum to improve basified soil, and concluded that the optimal irrigation has much to do with conducting ways of gypsum. 本文运用土柱模拟石膏改良碱化土壤的过程,认为最佳灌水量与石膏的处理方式有关,石膏与土混匀的处理只需保证最佳灌水量为134.47m3/hm2即可。
Cavernous basified fibroin was prepared from degumed silk which pretreated with dilute alkali solution and served as supporter for immobilization of α amylase to form the basified fibroin immobilized α amylase, BFIA. 脱胶蚕丝用稀碱溶液处理后制成多孔的碱化丝素,经物理吸附方法固定α-淀粉酶,制得碱化丝素固定化酶。
Conformation of Optimal Irrigation During Course of Gypsum Improving Basified Soil& Select 20 cm as Planning Improvement Layer 石膏改良碱化土壤过程中最佳灌水量的确定&选定20cm为计划改良层
After that, the reaction solution was basified, concentrated and alcoholized. The yield reached 88%. Clindamycin 3,4-isopropylidene was synthesized by Clindamycin Hydrochloride at room temperature. 反应液直接碱化、浓缩、醇化得到盐酸克林霉素,收率达到88%。盐酸克林霉素在室温下制备丙叉克林霉素。
