三元体系Mg^2＋／Cl^—,Borate—H2O25℃相关系和溶液性质的研究

用等温溶解法测定了Ｍｇ＾２＋／Ｃｌ＾－，Ｂｏｒａｔｅ－Ｈ２Ｏ三元体系２５℃时的溶解度，此三元体系等温溶解度图为简单共饱型，它的平衡固相分别为三方硼镁石（Ｍｇ２Ｂ１２Ｏ２０·１５Ｈ２Ｏ）和ＭｇＣｌ２·６Ｈ２Ｏ，未产生新的复盐或固溶体。拟合了ＭｇＢ６Ｏ１０随ＭｇＣｌ２浓度变化的溶解度曲线方程，并且对平稳溶液的物化性质（密度、粘度、折光度、电子率、电导、ＰＨ值）进行了测定，用半经验公式描述了一些物化性质     

某些镁硼酸盐溶解及相转化的研究

进行了章氏硼镁石和三方硼镁石在纯水以及某些盐溶液中的溶解平衡及相转化研究。首次发现三方硼镁石在水中的转化是分两个阶段进行,从而证明尼古拉耶夫等对２５℃时ＭｇＯ－Ｂ２Ｏ３－Ｈ２O体系的研究中,三方硼镁石与章氏硼镁石的共饱点实际上是三方硼镁石向多水硼镁石发生转化的一个中间点。报导了水溶液中的某些盐类对章氏硼镁石和三方硼镁石溶解平衡及相转化有一定的增溶或阻滞相变的作用。从这些溶解转化规律中可以对盐湖镁硼酸盐的形成及其转化规律提供物理化学解释。

Ｈ＾＋,Ｌｉ＾＋,Ｍｇ＾２＋／Ｃｌ＾－－Ｈ２Ｏ四元体系０℃,２０℃,４０℃的溶解度预测中需要大量参数,而这些参数的获得,依赖于盐酸－碱金属氯化物－水三元体系和ＨＣｌ－ＬｉＣｌ－ＭｇＣｌ２－Ｈ２Ｏ四元体系的热力学性质。总结了近５０年来国内外对上述体系的热力学性质的研究,为Ｈ＾＋,Ｌｉ＾＋,Ｍｇ＾２＋／Ｃｌ＾－－Ｈ２Ｏ四元体系０℃,２０℃,４０℃的溶解度预测奠定基础,同时为Ｐｉｔｚｅｒ模型增添更合理的

Deserts and Aeolian Desertification in China: Book review and some thoughts

Desertification is a global phenomenon that affects about two billion people. It occurs in arid zones where the annual precipitation is below 400 mm, partic- ularly in the marginal areas of the world＇s largest deserts. It is a result of water and wind erosion, over- grazing, global warm-ing, improper soil cultivation, and increased pressure ot population growth, and it causes degradation of soil and natural and agricultural vegetation. The direct result is less food for people and livestock, which influences pop- ulation and animal husbandry fluctuations. Despite ef- forts to combat and reduce desertification, the affected areas are annually increasing.
