The intense eluviation and weathering of soil with groundwater and run - off result in the enhancing of capacity of transference of some elements, such as si, al, fe, mn. the chemical reactions of the colloid particles in the soil water make those crannies or holes filled by some epigenetic clay minerals and quartz. then a great deal of white reticulate clay comes into being in the quaternary laterite of the dongting basin
地下水和地表水強烈的淋溶作用使土壤中硅鋁鐵錳等元素的遷移能力增強，土壤膠體粒子之間的化學反應，使得這些孔隙空間在後期逐漸被次生黏土礦物和石英所充填，最終，在洞庭盆地第四系紅土地層中形成大量的蠕蟲狀和根狀白色網紋。 -
On the basics of briefly summarizing the research and application presents of building coatings and nano - composite building coatings in domestic and overseas, presented a creative approach of modified exterior building latex coatings applying inorganic nano - powders and its " compound. systematically studied the effect of factors such as nano - materials " category, additive capacity, dispersing method on the behavior of exterior building coatings " weathering resistance, scratch resistance, water resistance and alkaline resistance etc. studying on uv - vis optical property of nano - powder materials and its " compounds turned up that nano - tio2, nano - sio2, nano - zno have excellent characteristics to uv shielding ; dispersing system of polybasic nano - composite materials owned higher uv shielding capability than single disperse system
本文在簡要敘述國內外建築塗料和納米復合建築塗料的應用研究現狀的基礎上，提出了使用無機納米粉體及其復合材料改性建築外墻乳膠漆的創新思路，系統地研究了納米粉體材料的種類、添加量、分散方式等因素對外墻乳膠漆耐候性、耐洗刷性以及耐水、耐堿性等性能的影響，成功地開發了納米改性建築外墻乳膠漆產品，並完成了外墻乳膠漆用納米助劑的初步開發工作。 -
Abstract : this paper, by analyzing the effect of differences of mineral structure of 2 1 layer minerals, the properties of their interlayer charge and changes of some properties caused by weathering on the attractive force for interlayer cation, reached the conclusion that : the fixation capacity is determined by the ratio of the total amount of interlayer charge and that of tetrahedral charges. the relationship of interlayer cation fixation and octahedral structure of secondary minerals is probably different from that of primary minerals. the oxidation and reduction of variable valence cations can greatly influence the cation fixation capacity
文摘:分析2 1型礦物的結構差異、層間電荷性質以及在風化過程中某些性質的變化對層間陽離子吸引力的影響，對已有報道中一些矛盾的結果或不具普遍意義的結論進行了討論.得出幾個較為明確的結論：層間總電荷與四面體電荷所佔比例大小共同決定礦物對層間陽離子的固定能力；原生礦物中八面體結構與層間陽離子固定間的關系對次生礦物而言，也許並不一致；八面體中可變價陽離子的氧化還原，可導致礦物固定陽離子能力發生較大變化 -
Abstract : compared with soil destroyed pattern of vertical force and its controlled factor of bearing capacity, it is concluded that pile capacity and its tip resistence have some difference when soil with the same physical mecanic property is used as natural foundation and pile tip resistent layer. whereas the middle weathering rod stratum hasn ' t this property, that is to say it has the same bearing capacity and pile tip resistence
文摘:通過豎向荷載下土（巖）體的破壞模式及其承載能力控制因素的比較，論述了物理力學性能相同的土層作為淺基礎的天然地基與樁端持力層時，承載力值與樁端阻力值應存在一定的差異；而中（微）風化程度的同一巖層作為天然地基與樁端持力層時，不具有這方面的差異性，承載力值與樁端阻力值應該相等。 -
So far, most related researches and achievements have showed that acid rain has certain impact on functions of a soil ecosystem. such as leaching of soil base - exchangeable ions, heavy metals and microelements, nitrogen, contents of sulfur and phosphorus nutrients, soil acidification, population and activities of soil microbes, soil buffer capacity, soil sensitivity to acid rain, soil structure and weathering status of soil minerals, and so on
現有的大量研究表明，酸雨對土壤生態系統的功能特性，包括土壤的鹽基離子以及重金屬與微量元素的淋溶、土壤營養、土壤酸化、土壤微生物數量及其活性、土壤緩沖性能、土壤對酸雨的敏感性、土壤結構、土壤礦物風化等方面均會產生一定的影響。 -
