The way to get the solution for the soil alkalization is pointed. 本文对绿洲生态系统的动态稳定性作了初步探讨。
In the course of experiment, the relation between ratio n (SO42-/Fe2+)and alkalization of PFS is investigated. 在制备过程中,实验重点考察SO42-/Fe2+的比值n和PFS盐基度之间的关系。
Soil salinity varied sharply in the zone, showing an obvious trend of alkalization. 垦区的土壤含盐变异强烈,碱化倾向明显;
The equations of linear regression in these parameters of alkalization are analysed. 建立了各碱化参数之间的线性回归方程,并对地下水体的碱化危害程度进行了评价。
The machine's major used is the alkalization and dehydration in the course of fat oil's refinement. YLYG系列脱色锅: 属于间歇性脱色设备,用于油脂的脱色、干燥、冷却等。
Carboxymethyl chitosan (CMC) was prepared by a two-step alkalization and refined by the method of isoelectric point. 本论文采用了两步加碱的新方法制备羧甲基壳聚糖(CMC),并利用等电点沉降法精制CMC。
