Based on the two cruises investigation in Acipenser sinensis Natural Reserve and its adjacent waters (31°19.58'N-31°38'N, 121°32.08'N-122°11.65'E) in May and August 2004, the seasonal variations of species composition and quantitative distribution of fish eggs and larvae in the study area were studied, with the relevant environmental affecting factors analyzed. The results showed that in study area, the species composition and quantitative distribution of fish eggs and larvae varied remarkably in different seasons.

The results indicated that there were six types of sensilla, namely, finger-like sensilla, platcodeum sensilla, trichoid sensilla, ampullaceous sensilla and chaetic sensilla on the antenna of two wasps. The type, number, and distribution patterns of the antennal sensilla were similar in the two species, but the differences between two sexes were significant.

结果发现，在两种寄生蜂的触角上着生着6种感器，分别为指形感器、板状感器、毛形感器、坛形感器、刺形感器、蒲姆氏鬃；两种桑天牛卵寄生蜂触角感器的种类、数量及分布模式在种间没有明显差异，但在种内雌雄个体间差异较为显著。

The Antennal ultrastructures of the two closely related wasp species, Aprostocetus prolixus and Aprostocetus fukutai, were observed by scanning electron microscope. The types, numbers, morphological characteristics and distribution patterns of the antennal sensilla of the two species were described, and the differences between two sexes were compared too.

利用扫描电镜观察了同属的桑天牛卵啮小蜂和桑天牛长尾啮小蜂的触角感器，对这两种寄生蜂触角感器的种类、形态、数量及分布进行了描述，并对雌雄两性触角之间的差异做了比较。

The pattern of vertical distribution of organic matter in mangrove soil reflected the roots distribution. Surface roots were abundant in Avicennia marina forest, so organic matter of soil in top layer (0-20cm) was the most there. However, the organic matter of soil in Kandelia candel forest was the most in middle layer (20-40cm) because roots were abundant in middle layer while there were fewer roots on surface soil. Content of organic matter in bottom layer (40-60cm) was generally lower in two mangrove forests.

1红树林土壤有机质的垂直分布模式反映了根系的分布状况，在地表根系发达的白骨壤林，表层土壤有机质含量高，而在地表少根而根系多集中分布于中层的秋茄林，中层有机质含量高，下层土壤有机质含量一般较低。

A hypothetical drained cell model retrofitted from a 160kA Hall-Heroult cell was set up to calculate the current distribution in the cathode when the anode bottom and cathode top surfaces were declivous. Two half anode-cathode slice thermo-electrical models with the collector bars installed slopingly or horizontally were adopted to calculate the potential drop and electricity distribution of the cathode.

摘 要：将某厂现有的160kA Hall-Heroult铝电解槽改造成导流槽后，在阴极上表面和阳极底面呈斜坡状的条件下，计算了采用不同阴极导杆安装方式时阴极的电位和电流分布，即通过建立导流槽内部从阳极到阴极的一个半切片电热场模型，用有限元法分别对水平和平行于阴极斜坡两种不同导流槽阴极导杆的安装方式下阴极电位和表面电流密度分布进行了计算。

So we adopted the isotope marking method in order to know the distribution of BBP in male and female mice. The result indicated 〓H-BBP presented the first-order kinetics and matched the open two-compartment model. Distributional half-life was about 20 minutes and eliminable half-life was about 6-7 hours. As α(the speed constant of distributional phase) was about ten times β(the speed constant of eliminable phase), this compound had a fast distribution and a low elimination.

为了揭示BBP致毒有明显性别差异的原因，采用同位素标记方法示踪BBP在雄、雌动物体内的归趋，结果表明：BBP在动物体内呈一级动力学线性过程，符合二室开放模型，分布半衰期为20min左右，消除半衰期为6-7hr左右，分布相的速度常数α是消除相的速度常数β的10倍左右，说明该化合物在体内的分布较快、消除慢的特征。

结果表明，采用合理的正反胀形可以很好地改善成形件的厚度不均匀性并大大提高成形极限，实验验证了仿真和实验结果相吻合。

According to the distribution of species and amount, the author makes a PCA analysis to the different habitats. The analysis of hierarchical cluster to different habitat is according to the distribution of species. According to the results of the two ways of analysis and the factual condition of environment, the environment of Daqinggou is divided into 3 types of habitat that are described as the hygric plant community in the bottom of ditch, xerophytic plant community in the top of ditch and single type plant community.
