Al impurity, the floatabilities of hematite and aegirine were resemble, which is contributed to the existence of structrual iron ion on surfaces of both minerals. It is the structrual iron ion that accelerates the floatability of aegirine greatly and leads to difficult separation with hematite. 2. The basic mechanism of actions of fluorosilicate salts as selective depressants of aegirine during the direct flotation of hematite was investaged detaily by using FTIR and XPS spectrocppy, fluorosilicate salts are poor depressants for hematite, but are very strong depressants for iron-containing silicate such as aegrine in weakly acid medium, which can enlarge the flotation differences between two minerals.

运用X射线衍射、俄歇能谱等测试手段研究了赤铁矿与钠辉石纯矿物的晶体结构特征，表面破裂面的元素组成与赋存状态，发现在白云鄂博不同的矿床（氧化矿段，原生矿段，风化矿段）存在着三种颜色与可浮性均有所差别的钠辉石，其可浮性的差异主要是由于表面含铁量及Ca、Al等杂质含量的不同而引起的，结构Fe〓的存在导致钠辉石可浮性剧增从而与赤铁矿难以分离。

Results:Normal segment:DEM 8.89±1.21mm,VDEM2.30±0.76cm/s;Hypokinetic segment:DEM 4.56±0.53mm,VDEM 1.89±0.35cm/s;Akinetic segment:DEM 2.13±0.45mm,VDEM 0.95±0.07cm/s.There was a significant overall difference in DEM and VDEM (P0.0001)among wall motion grades.1/3 VDEM was greater than 2/3 VDEM in normal(P0.0001)and hypokinetic(P0.05)segments,though 1/3 VDEM was slower than 2/3 VDEM in akinetic segments(P0.0001).There was also high correlation between 1/3 DEM and 1/3DEMF in both normal(r＝0.81,P0.0001,y＝0.75x＋0.16)and OMI(r＝0.91,P0.0001,y＝0.74x＋0.10)groups.Conclusion:Analysis of color kinesis image can quantitatively assess regional and global diastolic function.

However, those decreased in secondary forest dominated by Alchornea trewioides, Mallotus conspuyrcatus, Eurycorymbus cavaleriei with lower species diversity. The SOM contents in rock-soil (110 g kg-1) and soil surface microhabitat (77 g kg-1) in gentle slope decreased significantly, which were only 32% and 35% of that in primary forest, respectively; but there were not significant differences in SOM, TN and AN contents in depression between the two vegetations.

以红背山麻杆、广西野桐、伞花木等为优势种的次生林，物种多样性较原生林低，SOM、TN、AN含量也低，缓坡石土面和土面小生境的SOM分别为110 g kg-1和77 g kg-1，是原生林的32%和35%，下降幅度最大，其次为陡坡，而洼地的差异不明显。

All the 〓-fixing legumes other than Lespedeza bicolor had higher %FNDA than Lespedeza bicolor, and showed between-and among-species variation, with the Amphicarpaea capillipes being the highest (100%). Vicia unijuga (66. 4% on average), was comparable to the related studies reported by foreign researchers.

除胡枝子之外的其他豆科植物的％FNDA都高于胡枝子，且存在种间差异，以三籽两型豆最高（100％），歪头菜最低（平均66.4％），这些结果与国外相关研究接近。

DNA C-values might be one of important indices in the evaluation of angiospermous invasiveness. To test this viewpoint, we compared DNA 1C-values and basic genome sizes in 3,676 angiosperms. The results suggest that:(1) the two nuclear values vary greatly among different groups, e.g., significantly higher in herbs than in trees, in monocots than in dicots, in perennials than in non-perennials;(2) the two nuclear values both have significant effects on plant invasiveness, especially in herbs, dicots, monocots, perennials, non-perennials, diploids, polyploids, Compositae, and Poaceae, while not significant in trees and Fabaceae.

DNA C值与被子植物入侵性密切相关，为考察应用DNA C值评估被子植物入侵性的可靠性和局限性，我们统计分析了全世界范围内3676种被子植物的DNA 1C值（配子未发生DNA复制时的染色体DNA含量）及基因组大小（单个染色体组的DNA 含量），结果表明：1）DNA 1C值和基因组大小在被子植物不同类群中差异极大，例如在草本植物中显著高于木本植物，单子叶植物显著高于双子叶植物，多年生植物显著高于非多年生植物；2）两项指标都与被子植物入侵性显著负相关，尤其是在草本植物、双子叶植物、单子叶植物、多年生植物、非多年生植物、二倍体、多倍体、菊科和禾本科中，然而在木本植物、豆科植物中其与植物入侵性无显著关系。
