The mechanism of vegetation restoration on degraded karst regions has been a research focus of soil science and ecology for the last *** an attempt to preferably interpret the soil microbiological characteristic variation associated with vegetation restoration and further to explore the role of soil microbiology in vegetation restoration mechanism of degraded karst regions,we measured microbial biomass C and basal respiration in soils during vegetation restoration in Zhenfeng County of southwestern guizhou Province,*** community level physiological profiles(CLPP) of the soil microbial community to were estimated determine if vegetation changes were accompanied by changes in functioning of soil microbial *** results showed that soil microbial biomass C and microbial quotient(microbial biomass C/organic C) tended to increase with vegetation restoration,being in the order arboreal community stage > shrubby community stage > herbaceous community stage > bare land *** trend was found in the change of basal respiration(BR).The metabolic quotient(the ratio of basal respiration to microbial biomass,qCO 2. decreased with vegetation restoration,and remained at a constantly low level in the arboreal community *** of the CLPP data indicated that vegetation restoration tended to result in higher average well color development,substrate richness,and functional *** utilization of specific substrate guilds was highest in the arboreal community *** component analysis of the CLPP data further indicated that the arboreal community stage was distinctly different from the other three *** conclusion,vegetation restoration improved soil microbial biomass C,respiration,and utilization of carbon sources,and decreased qCO 2.thus creating better soil conditions,which in turn could promote the restoration of vegetation on degraded karst regions.

A cyclic plasticity model is used into finite element (FE) method to obtainthe details of elastic-plastic stress-strain in the bolts under cyclic axial loading. Two criteriain multiaxial fatigue are employed to predict fatigue lives of bolts. The predicted fatigue livesare in favorable agreement with the experimental results for machined bolts.

There are four subtypes. namely, Ia, Ib, Ic and Id of the Early Carboniferous bauxite deposits of the old weathered crust type in guizhou, Sichuan, Hunan and Hubei provinces. They are all distributed in the Upper Yangtze old land. As a result of the Hunan-guizhou palaeo-faulting, the crust on the northern side of the fault was uplifted and became land, thus suffering denudation. The bauxitic substances left in the weathered crust evolved and were reworked into bauxite. On the other hand, the crust on the southern side of the fault sank and remained to be part of an ocean. The bauxite deposits of Ia and Ib subtypes were formed by in-situ enrichment of residual bauxitic substances in the weathered crust of the old land, but bauxite deposits of Ic and Id subtypes resulted from transportation, accumulation and sedimentation of allothogenous bauxitic substances on the weathered crust of the old land. The processes of transportation may be distinguished as dry transportation and wet transportation, both of which proceeded under atmospheric conditions.

利用多种方法在不同基组水平下,对 TiO 基态分子的几何构型进行优化.通过对比选用密度泛函(DFT)B3LYP/6-311+G 方法研究在强外电场(—0.02.a.u.～+0.02.a.u.)作用下的 TiO 分子的基态键长、总能量、HOMO 能级、LUMO 能级、能隙及势能曲线的变化规律.结果表明:在一定外加电场范围内,随电场强度的增大,分子键长变小;总能量升高;HOMO 能级、LUMO 能级均依赖外加电场方向,随电场的增大而降低;能隙不依赖于电场方向,随电场强度的增大而减小;势能曲线在外电场中有"平移"效应,其中反向电场对势能曲线的影响较甚,会导致势能曲线偏离势能零点,进而破坏原有的"势能平台".

The kinetics and the influence of time on the solid metal manganese nitriding were studied by means of vacuum resistance furnace, X ray diffraction technique and LECO TC-436 Oxygen/Nitrogen Determinator. The longer the nitriding time, the more amount the nitrogen pick-ups. Except for trace of oxide MnO developed, the metal manganese can thoroughly be nitrided into MnN and a little-phase (the stoichiometric components as MnN) with the nitriding time lasted. A kinetic model is developed to reveal the nitriding situation and agrees well with the experimental results.

通过对茂兰喀斯特森林林隙更新状况及林隙环境特征的调查,分析了茂兰喀斯特森林主要树种在不同大小和年龄林隙中的更新密度、无性繁殖特征以及林隙特征、立地条件等因素对树种更新密度的影响。结果表明:不同树种的更新密度随林隙大小的变化因树种的耐荫性强弱而存在差异,表现为耐荫性较强的树种在小面积林隙中更新密度较大,而耐荫性较弱树种在大面积林隙中更新密度较大;主要树种的更新密度随林隙年龄的变化曲线有单峰型和双峰型两种类型,可用多项式进行最好的拟合;大部分树种在林隙中的萌枝率较非林隙中的高,无性繁殖的幼苗数量随林隙面积的增大而增多,随林隙年龄的增大而减少,表明林隙的形成对喀斯特森林的无性繁殖也有显著的促进作用,无性繁殖亦是喀斯特森林的重要更新对策;林隙面积、年龄、枯落物厚度及小生境类型等是林隙树种更新的主要影响因子。
