The phosphorus in water and sediment collected at different time from the Xiangxi River were analyzed. The results indicated that the phosphorus pollution have significant relations to human activities (especially the phosphorus industry). The concentrations of total-phosphorus (TP), total dissolved phosphorus (TDP) and dissolved phosphorus (DP) in Dec.2.04 were higher than those in Jul. 2.05; the TP contents of sites 15 and 16 were much higher than others’, the TP content of the largest site 16 was 1946.2.mg/kg in Dec. 2.04 and 1756.11mg/kg in Jul. 2.05, respectively, which was much higher than the average (1497.51mg/kg and 1369.38mg/kg, respectively). The TP content in the sediment of the Xiangxi River was from 1179.53mg/kg to 1851.2.mg/kg. The TP contents of most sites except site 18, 19 and 2. were higher in Dec. 2.04 than those in Jul. 2.05. The aluminium-phosphorus (Al-P) content in the sediment was obviously higher in Jul. 2.05 than that in Dec.2.04, which indicated that the stability of Al-P has a significant relation to the change of season.

It is commonly acknowledged that the development of gout is a multi-step process,ranging from asymptomatic hyperuricemia,acute gouty arthritis,intercritical gout to chronic tophaceous gout [1].Almost 80% of patients after the first gout attack will suffer a recurrence within 2.years [2..With the accumulation of uric acid and the deterioration of the disease,acute attacks might become polyarticular in chronic gout ***,the attacks will be more common and tend to last longer and become progressively ***,we can conclude that one of the important characteristics of gout disease is its recurrent attacks and no rule to *** acid as a single evaluation indicator for clinical diagnosis is insufficient to satisfy versatile properties of the *** this work,a new strategy,called graphical index of separation（GIOS） [3] were developed to select the important metabolites from the serum sample in order to understand metabolic changes induced by gout disease based on metabolic target *** most significant difference of GIOS for the selection of variable is that the importance of one single variable is not influenced by the inclusion or exclusion of another variable from all variables.

Gabor X ray in line holograms are recorded with a photoresist at Hefei National Synchrotron Radiation Laboratory. An Atomic Force Microscope (AFM) is used to read the X ray holograms of minute granules recorded on photoresist PMMA. Digitized hologram is reconstructed by numerical method. The granules with a size less than 0.3 μm can be resolved in the reconstructed image. So the estimated resolution reaches the level of submicrometer.

利用线粒体控制区序列片段(史氏鲟,42.bp,达氏鳇,434bp)分析检测了两个养殖场留做后备亲鱼的史氏鲟和达氏鳇的遗传多样性。在所检测的养殖史氏鲟后备亲鱼4个年龄群体共34个体中,发现5个单倍型,共有11个多态位点,占碱基总数的2.6%,无简约信息位点。不同单倍型之间有1～10个变异位点,占碱基总数的0.2.～2.4%。各单倍型之间的遗传距离为0.002.0.02.。单倍型多样性Hd=0.768,平均核苷酸差异数k=4.367,核苷酸多样性Pi=0.011。而分别来自2.养殖场的2.达氏鳇养殖群体都是1个群体仅1个单倍型,2.单倍型之间仅有2.碱基差异,遗传距离为0.005,遗传变异极度缺乏。结果提示在利用史氏鲟和达氏鳇后备亲鱼进行繁殖育苗时要充分注意近交的影响。

Gully Impact on Soil Moisture in the Gully Bank

Pedosphere 2006年第3期16卷 339-344页

作者： ZHENG Ji-Yong WANG Li-Mei SHAO Ming-An WANG Quan-Jiu LI Shi-Qing State Key Laboratory of Soil Erosion and Dry Land Farming on the Loess Plateau Institute of Soil and Water Conservation Chinese Academy of Sciences and Northwest A＆F University Yangling Shaanxi 712100 （China） Institute of Geographic Sciences and Natural Resources Research Chinese Academy of Sciences Beijing 100101 （China） College of Life Sciences Northwest A＆F University Yangling Shaanxi 712100 （China）

In order to preliminarily look at rules for soil moisture changes in the bank of the gully and to provide some recommendations for vegetative restoration in gully bank regions in the Loess Plateau, changes of soil moisture with depth and distance to the gully edge and their dynamic changes with time were observed to study the soil water characteristics in the bank of the gully. The results showed that soil water content increased with increasing distance from the gully edge, whereas for the same time period, the closer the distance to the gully wall, the greater the water loss; and that the influential distance of side evaporation decreased as depth increased.
