According to fractal theory, R/S analysis on the typical colluvial landslides is complete, finding that the parameter of Hurst decreases just at the time before the landslide took place. This research result shows that Hurst parameter is an effective nonlinear displacement parameter and it also has a very explicit forecast function.

结果表明，基质引发处理能明显提高黑籽南瓜种子发芽势、发芽指数和活力指数，明显减少种子平均发芽天数；基质引发温度明显提高幼苗干鲜质量和根体积等，而基质湿度对幼苗生长性状影响不显著。

Species richness and Pielou evenness index were used to measure species diversity. Species richness in polluted area was 32-67, while in control area it was 47-82. Pielou evenness index of tree layer was 0.1161-0.8509, while those of shrub layer and herb layer were 0.1763-0.3249 and 0.0443-0.2601, respectively. The results showed that both species richness and Pielou evenness index were influenced by the point source pollution. Species importance values showed significant differences between polluted area and control area. Dominance of different species had changed, and some species even disappeared under the pressure of pollution, indicating a process of species replacement in plant communities. Such species replacement can provide a scientific basis for species selection for restoration of human-damaged ecosystem. The natural regeneration of Quercus variabilis was insensitive to pollution, while Cupressus funebris was effected seriously.

仅在污染区中出现的物种数量远低于仅在对照区中出现的物种数量；(2)可分出4种基本的群落类型：马尾松林、柏木林、栓皮栎林和马尾松＋栓皮栎林，各群落特定层次的物种丰富度指数以及Pielou均匀度指数在污染区与对照区之间存在显著差异；(3)污染胁迫下，物种在群落中的生态优势度发生了变化，反映了群落中不同物种相互替代的过程，这种物种的替代可为今后受损生态系统人为恢复过程中物种的筛选提供一定的理论参考；(4)对群落中王要物种更新的调查发现：栓皮栎林对污染不敏感；柏木林污染区与对照区幼苗数量及分布格局均有明显差异，污染条件下群落未来演替受到严重干扰。

Based on the problems of low viscosity index and the acidity increasing in the lubricating base oil,it has been found that the unstable quality of the crude oil was the root cause to effect on the quality of the base oil by analysis for long time;the low viscosity index and the higher acidity were resulted from the low paraffinicity and the high content of aromatics,cyclane.

针对润滑油基础油相继出现的黏度指数降低、酸值升高等问题，跟踪分析了润滑油基础油质量，认为原油的变化是造成润滑油基础油质量变化的根本原因；基础油组成中烷烃含量降低，芳烃和环烷烃含量上升是其酸值上升和黏度指数下降的内在原因。

The results show that the value of burning rate pressure exponent of propellant and its change law can bring about a great change of interior ballistic behavior, The new type high-energy propellant whose burning rate pressure exponent is decrescent as pressure increasing can obtain higher interior ballistic piezometric efficiency, and reduce the sensitivity of bore pressure and muzzle velocity on loaded conditions of propellant.

结果表明，发射药燃速压力指数的大小及其随压力的变化规律对内弹道性能有很大的影响，对于燃速压力指数随压力升高而减小的新型高能发射药，可获得较高的内弹道示压效率，降低膛压和弹丸初速对发射药装填条件的敏感性。

The diversity index of soil dematiaceous hyphomycetes was the highest but the evenness was lower in town-oasis, whereas in desert and gobi the diversity index was obviously lower, and the species evenness was higher.

在小镇-绿洲生境中，土壤暗色丝孢菌的Shannon-Wiener多样性指数最高，均匀度较低；而在沙漠和戈壁生境中多样性指数明显较低，而物种的均匀度较高。

It is convenient for sinter to be leached, and the secondary reaction appears little. The slurry after sinter leaching is transferred into autoclave for desilicification at about 170℃, and the siliceous modulus of solution reaches more than 200. Then some lime is added for deep-desilication at normal pressure, the siliceous modulus of solution increases more than 600 even if the Al2O3 content is more than 200g/L.The SiO2 coefficient in hydrate garnet from deep-desilication is more than 0.28.
