碱化土

From purification of run-of-mill, acidification, basification , gelation to crystallization, the factors effecting the quality of molecular sieve4?

以钙基膨润土为原料，通过原矿提纯、酸化、碱化、成胶、晶化工艺，探讨了影响分子筛质量的因素。

But the result of improvement soil translated alkaline soil into alkalier soil. Not onlu it is unavoidable and subsisted of stabilization in commix tier of gypsum, but also it destroyed direct improvement process. It is imported find what solved seepage problem of gypsum in the study. In configured duality structure of improvement soil, it needs abundance seepage gypsum in commix tier into noncommix tier in order to losing seepage capacity reduce in all deepness of improvement soil.

碱土改良过程中石膏渗漏损失最高可达到石膏施入量的40%以上，而改良结果碱土只转化为重碱化土；在石膏混合层内，它是一种不可避免的、稳定存在的且直接破坏土壤改良进程逆流；因此解决石膏渗漏问题亦是在本文研究工作中的重要发现：配置二元结构改良碱土中，正需要石膏混合层中大量石膏渗漏，以改良非石膏混合层，并使整个计划改良深度内的渗漏损失降为零。

In the alluvial fan edge parts, mainly meadow marsh soil and meadow saline soil; this to the desert between, places the desert soil salinization and alkalization the main agricultural use value is not high.

在冲积扇缘部位，主要是草甸沼泽土和草甸盐土；由此至沙漠之间，则以盐化和碱化的荒漠土为主，农业利用价值不高。

Saline soils and the rice paddy soils developed on saline soil.were sampled from Zhenlai county of Jilin Province in this paper.The main alkalize characteristic parameters,including pH,cation ex- change capacity,exchangeable Na~+,exchangeable sodium percentageand the content of wa- ter-soluble salty,were measured.

本文中的土样采自吉林省镇赉县，在盐碱土的典型区域，选择了未开发利用的盐碱土和在盐碱土基础上开发为稻田土壤的剖面，测定计算了土壤 pH 值、阳离子交换量、交换性 Na~+、碱化度和水溶性盐总量等主要碱化特征参数。

Though the changes of all indexes are within the range of nonsaline and nonsodic soils, the soils affected by salt in glyphosate aqueous solution tend to salinesodic soils.

虽然土壤各项盐化和碱化指标的变化都还在非盐化和非碱化土范围内，但有盐化和碱化的趋势。

Combinating the siol column and potted plant experiment synthesize analysis that the soil alkalinity below 30% can be all improved by hydraulic and agricultural measure without the chemical amendment. When the alkalinity is over 30%, however, the alkaline soil must be made use of the chemical measure gathering water conservancy to attain improvement .

结合土柱试和盆栽试验的结果综合分析，在土壤碱化度低于30%的轻、中度碱化土壤通过水利与农业措施相结合的办法而不用化学改良剂就可以改良好；而碱化度大于30%的土壤，必须在水利措施的配合下，利用化学改良剂才能达到改良的目的。

The preparation method comprises the steps as follows: pulverizing; alkalizing and stewing plant straw to obtain fibrous pulp; mixing the fibrous pulp with bentonite and milling; conducting sodium treatment, chemical modification and purification to obtain modified composite bentonite pulp; separating, drying, etc., to prepare the composite fibrous material.

本发明涉及一种路用秸秆复合纤维材料的制备方法，该制备方法是将植物秸秆经过粉碎、碱化、蒸煮后的纤维浆与膨润土经过磨细、纳化、化学改性和提纯后得到的改性膨润土浆复合，并经分离、干燥等制备出的复合纤维材料。

There are thinks the double features of saline and alkaline for the formation and evolutionprocess of the salinization soils in this region,the generation intensity and scale are related withgeomorphological types,shallow water geochemical types,shallow water table and soil structureetc.,presents the quantity relationship between the salinization degree of the soils,shallow watertable and mineralization,expounds the four stage and seasonal succession features of slattransference and inversion,discuss the interaction between ions in shallow water and soils and thethe regularity of the salt transference and accumulation under freeze-thaw action.

本文在野外调查、监测及实验研究的基础上提出松嫩平原盐渍土的形成过程存在盐化与碱化双重作用，其发生强度和规模与地貌、潜水类型、径流条件、潜水水位、土壤结构有关，提取出潜水埋深、矿化度与土壤盐渍化程度关系的定量指标，以及土壤盐分迁移转化季节性变化的四个阶段及其特征。同时重点研究了潜水与土壤之间元素交互作用及冻融作用下盐分迁移和聚积规律，为土壤次生盐渍化的防治提供了理伦依据和技术支撑。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
