The results show that the PSD fractal dimension of Light chestnut soil, Yellow cultivated loessial soil, Orthic dark locssial soil, Orthic cinnamon soil (stratified old manured loessial soil), Fluvo-aquic soil, Orthic gray desert soil, Orthic black soil, Orthic yellow-brown earth, Orthic yellow earth, Orthic ted earth and Orthic lateritic red...

结合上壤颗粒表面分形特性及土壤粘附的基本原理，探讨了土壤PSD分维对土壤—固体表面粘附行为的影响。PSD分维高的土壤与固体表面粘附力大，与固体表面发生明显粘附的起始含水量提高，发生明显粘附的含水量区间增宽。

The research history of Earth system can be divided into three stages:Ancient, Great Divide and Great Syncretic stages, and that the Earth System Science will be the mainstream in Earth science research for a long time.

简略回顾了地球系统的研究历史，指出人类数千年来关于地球系统的研究可分为古代、大分化和大融合3个阶段，提出&地球系统学&在今后相当一段时间内将是地学研究的主流。

In this dissertation, two series of rare earth initiators: rare earth tri (2, 6-di-tert-butyl4-methylphenolate) and rare earth calixarene complex have been developed to ring-opening polymerize 2, 2-dimethyltrimethylene carbonate, trimethylene carbonate and ε-caprolactone at mild conditions. Both the polymerization features and mechanisms are discussed in details.

本论文为环碳酸酯、内酯的开环聚合开发了两类新型低毒性稀土催化剂：三(2，6-二叔丁基-4-甲基苯氧基)稀土配合物和对叔丁基杯芳烃稀土配合物，都可以在温和的反应条件下单组分引发2，2-二甲基三亚甲基环碳酸酯、三亚甲基环碳酸酯和ε-己内酯聚合，合成各种分子量的均聚和共聚材料，考察了催化剂结构、聚合条件等对聚合的影响，深入研究了聚合机理。

In order to investigate the relation between the ligands and rare earth ions, in this dissertation, two new polyaza cryptands, two new tripyrazolone ligands, a macrobicyclic rare earth cryptates, a tripyrazolone and a tripodal ligands rare earth complexes have been synthesized.

为了进一步研究和探讨穴醚、吡唑啉酮、三脚架化合物配体对稀土元素的配位作用，论文首次报道了两个新氮杂穴醚配体、两个新三脚架吡唑啉酮结构配体、一个系列大二环新型的稀土配合物、一个系列三脚架吡唑啉酮结构配合物、一个系列三脚架结构三酸配合物的合成。

Within Earth's unconscious is lost knowledge, agreements made without Earth's consent, or manipulations to Earth's field and form that have continued since ancient times, but now as the karma is released, can be untangled or undone.

地球的无意识内是丢失的知识、未经地球许可而缔结的协议，或自远古时代以来对地球能量场和形态的操纵，但现在当业力被释放，能被解开和脱去。

The result showed that Wote and PAM increased the average temperature of the earth's surface, temperatures of 10cm soil, 20cm soil and the lowest temperature of the earth's surface, but reduced the highest temperature of the earth's surface in reviving phase. Soil moisture was increased by using Wote and PAM, and the soil moisture of 0-30cm soil in florescence and fruiting phase was also increased.

结果表明，施用沃特和FAM降低了西瓜缓苗期的地表最高温度，提高了地表的平均温度、最低温度及10cm土层和20cm土层的土壤温度，增加了土壤的含水量，特别是开花坐瓜期0~30cm土层的土壤含水量。
