The results indicate that : 1. the main physical and chemical characteristics vary regularly : with rising of the altitude, there is a transition from silt > sand > clay to sand > silt > clay in the mechanical composition ; the argic horizon emerges below the altitude of 1600 meters ; the content of organic matter is enrichment, the content of organic carbon of epipedon is higher than 20 g / kg, while the content of organic carbon increases with increasing of altitude, and in the altitude of 3500 - 3700meters, the soils under the meadow have the maximum content organic carbon ; the soils appear acid - slightly acid reaction, the ph decreases appreciably and acid strengthen with increasing of altitude ; the soils higher than the altitude of 2500 meters are base unsaturated, indicating the soil leaching is strong, the ph and bs are distinct plus correlated ; the contents of sio2, al2o3, and fe2o3 of the soil body and clay are all relatively stabilization ; in the soil body, the content of sio2 is much high and cao is very little, the total contents of sio2, a12o3 and fe2o3 occupy 92 % of the mineral parts, the sequence of mineral elements is : sio2 > al2o3 > fe2o3 > k2o > mgo > cao > tio2 > mno
研究結果表明： 1太白山南坡土壤的主要理化性質隨海拔高度的上升呈有規律的變化：隨海拔高度上升，機械組成由粉粒砂粒粘粒逐漸過渡到砂粒粉粒粘粒，海拔1600m以下出現粘化層；土壤有機質豐富，表層有機碳含量一般在20g kg以上，有機碳含量隨海拔高度升高而相應增加，海拔3500 3700m的灌叢草甸植被下有機碳含量最高；土壤呈酸性或微酸性，並隨海拔上升， ph值略微降低，酸性增強，海拔2700m以上的土壤多呈鹽基不飽和狀態，表明土壤淋溶作用較強， ph值和鹽基飽和度呈極顯著正相關；土體與粘粒中的sio _ 2 、 al _ 2o _ 3 、 fe _ 2o _ 3含量相對比較穩定，土體中sio _ 2含量較高， cao含量較少， sio _ 2 、 al _ 2o _ 3和fe _ 2o _ 3含量之和約占土壤礦質部分的92 ，礦質元素含量的順序依次為： sio _ 2 al _ 2o _ 3 fe _ 2o _ 3 k _ 2o mgo cao tio _ 2 mno 。 -
The optimum conditions for air electrode preparation were shown as follow : 20 % ptfe and 20 % mno2 in active layer, thickness of active layer 0. 15 - 0. 25mm and the ratio of active carbon to ethine black 4 : 1 ; 60 % ptfe in the gas diffusion and waterproof layer, employing na2so4 as pore - making agents, thickness 0. 35 - 0. 45mm, colding forming and layer sequence catlytic layer / gas diffusion and waterproof layer / current collector layout ; employing 40 meshed nickel screen as current collector and thermal treatment temperature over 200
確定了制備空氣電極的優化工藝條件，催化層中ptfe含量約20 ， mno _ 2的最佳含量約為20 ，催化層中活性炭和乙炔黑的比例為4 ： 1 （質量比） ，厚度在0 . 15 - 0 . 25mm之間。防水透氣層中ptfe的含量約為60 ，以無水硫酸鈉作為造孔劑，厚度一般為0 . 35 - 0 . 45mm 。電極各層採用催化層/防水透氣層/集流體的排布方式，冷壓成型，熱處理對空氣電極的性能影響較大，熱處理溫度不低於200 。 -
After modification, main technologica and economic indexes have been improved and sequence casting has been realized, finished products of plain carbon and low - alloy grades through secondary annealing eliminated and billet hot delivery and charging primarily realized, which develops the modification of slab ccm at xinyu iron & steel co. ltd
改造后，方坯連鑄機主要技術經濟指標得到了提高，並實現了轉爐鋼全連鑄，消滅了普鋼、低合金鋼二火線材;消滅了二次化鐵;初步實現了方坯熱裝熱送;引發了新鋼公司板坯機改造。 -
Three phenanthrene - degrading bacteria were isolated from soil samples contaminated by oil, which are capable of using phenanthrene as sole carbon and energy sources, and were identified to be belonged to sphingomonas, strain zx4 as s. paucimobilis, strain zx6 as s. aromaticivorans and strain eva 17 not being identified to species, respectively, based on the results of physio - biochemical tests and the phylogenetical analyses of 16s rdna sequence
實驗結果分述如下： 1 、本研究從石油污染土壤中分離到3株菲降解細菌（ zx4 、 zx6和eva17 ） ，它們都能以菲為唯一碳源和能源生長。經鑒定3菌株都歸于鞘氨醇單胞菌屬（ sphingomonas ） ，其中zx4菌株為少動鞘氨醇單胞菌（ sphingomonaspaucimobolis ） ， zx6菌株為溶芳烴鞘氨醇單胞菌（ sphingomonasaromatics ） ， eva17菌株比較獨特，尚未能鑒定到種。
