It is concluded that, first, geochemical data of the surface soils can clearly distinguish two kind of soils, that is, juvenile soils, for example, purple soils, which inherits most geochemical characteristics of the parent rocks or materials, and anthropic soils, the geochemical characteristics of which have been greatly changed as the results of intensive impact from variety of agricultural uses. Second, different soils have typical indicator elements association respectively due to different parent rocks or materials and utilization, such as purple soils, yellow soils (low alkali and alkaline-earth metal contents and pH value), paddy soils (high organic element and heavy metal elements contents) and fluvo-aquic soils (high rock-forming accessory mineral elements contents) and so on. Consequently, it can be suggested that elements association is an important indicator for two key factors (parent materials and anthropic activities) of soil classification. Third, some differences exist between soil genesic classification and result of cluster analysis, because geochemical characteristics of surface soils can not completely represent the foundation applying to soil genesic classification, that is, condition and process of soil-forming, and soil property.

结果表明：浅层土壤的地球化学数据能较好地用来区分两类土壤，即紫色土一类的幼年土壤（在很大程度上继承了母岩、母质的地球化学特征）和受强烈人为活动水耕、早耕熟化的土壤（外来物质的不断加人显著地改变了浅层土壤原有的地球化学性质）；(2)各类土壤因母岩母质和利用方式不同，各具明显的标志性元素组合特征，如紫色土、黄壤（低碱和碱土金属元素和pH值）、水稻土（高有机元素、肥料元素和重金属元素）和潮土等，因此，这些元素组合是土壤分类两个要素的重要参照系；(3)浅层土壤的地球化学特征不可能完整地体现成土条件、成土过程和土壤属性这三个发生分类依据，因此，聚类分析结果与发生类型之间存在一定的差异。

Results: 1 The capacity of engulfment of A549 cells started enhancing at the 1h of preincubation with dexamethasone, reached the highest at the 4h of preincubation,At the 8h、24h of preincubation the capacity of engulfment evidently reduced. 2 Glucocorticoid cytosolic receptors antagonist RU38486 inhibited the improved engulfment ability by dexamethasone. 3Phagocytosing apoptotic eosinophils did not change the release of IL-6 and IL-8,but can inhibited the release of IL-6 and IL-8 from A549 cells stimulated by lipopolysaccharide. 4Increasely uptaking by dexamethasone also did not agitate the release of IL-6 and IL-8 from A549 cells. Conclusion: 1Dexamethasome improve the phagocyte capacity for apoptotic eosinophils of A549 cells by glucocorticoid cytosolic receptors, and the effect presents time-dependently. 2Phagocytosis of apoptotic eosinphils can degrade inflammatory reflection, so it is likely to be critical in the control of asthma inflammation.

结果： 1 A549细胞在地塞米松诱导后1小时吞噬能力开始升高，4小时吞噬能力达最高峰，8小时、24小时吞噬能力明显下降 2加入RU38486后抑制了地塞米松所增强的吞噬能力 3凋亡嗜酸粒细胞的吞噬并不能改变A549细胞释放IL-6和IL-8，但能抑制脂多糖刺激A549细胞后IL-6、IL-8的分泌 4地塞米松增加的吞噬也不激发A549细胞释放IL-6和IL-8 结论： 1地塞米松促进A549细胞吞噬凋亡的嗜酸粒细胞是通过A549细胞糖皮质激素胞浆受体发挥作用的，并且具有时间依赖性 2 A549细胞吞噬凋亡的嗜酸粒细胞能降低炎症反应，对哮喘炎症的控制具有重要意义

Changes of land use would make NPP decrease and NEP increase with a large range of about 77%. These changes do not only caused by the pixels with land use type changes, but also by the spatial interaction.

土地利用的改变使得NPP有所下降，NEP则出现了大幅地增长，增加了77%，这些改变不仅是发生土地利用方式改变的格点造成的，而且是空间上相互影响的综合结果。

of transitive closure based on equivalence relation, method of maximum fuzzy spanning tree based on fuzzy graph, and algorithm Fuzzy C-Means based on partition are more deeply investigated. Respectively, this thesis proposes an algorithm for document fuzzy clustering based on methed of transitive closure and an algorithm for document fuzzy clustering based on methed of maximum fuzzy spanning tree. Moreover, FCM is particularly studied from data standardization method, metrics method, and selection method of initial clustering prototype.

They interweave together each other, tend to changing constantly, power and shape , they fine long hair sometimes flow , sometimes congeal and stop , erupt sometimes irregular, disappear sometimes," some such things change like lights of forest like that in feeling of us, it hand in again and the overlapping:" Gather into certain form again when they have not offsetted and concealed each other, but this kind of form in often resolving, or break out in the fierce conflict for the passion, or become changed beyond recognition in this kind of conflict , all these things blend subjective reality make up man we call that inalienably for an organic whole " The inherent life " Thing promptly emotions human so-called.

它们相互交织在一起，不断地改变着趋向，强弱和形态，它们毫无规律地时而流动，时而凝止，时而爆发，时而消失，&这样一些东西在我们的感受中就象森林中的灯火那样地变化不定，相互交又和重迭&当它们没有相互抵消和掩盖时便又聚成一定的形状，但这种形状又在时时的分解着，或是在激烈的冲突中爆发为激情，或是在这种冲突中变得面目全非，所有这些交融为一体不可分割地主观现实就组成丁我们称之为&内在生命&的东西即所谓人类情感。

The stabilities of the extract from sanguisorba under different pH, light, heat, ultraviolet ray, oxidant, reducing agent and additive agents were studied. It was indicated the products could widely used in the condition of weak acid or neutral, while they were not stable to heat and light, so they should be used without light and at low temperature. The products had a strong ability to withstand ultraviolet ray. They could easily be oxidized and degraded by oxidant while they were not easily affected by reducing agent and were almost not affected by additive agents. The extract from the stem of sanguisorba was analyzed by UV and FTIR, showing that the structures of the active components were not changed during ultrasonic wave extracting.

研究了pH值、光、热、紫外线、氧化剂、还原剂以及添加剂对地榆提取物稳定性的影响，结果表明地榆提取物适合弱酸或中性条件下使用，使用范围比较广；但对光热稳定性较差，适合在避光低温的环境；具有很强的抗紫外线能力；氧化剂对地榆提取物稳定性影响较大，会加速其降解，还原剂对地榆提取物影响不大；其他添加剂对其稳定性几乎没有影响；并通过UV和FTIR光谱分析，超声波浸提没有对地榆根茎中有效成分的结构发生改变。
