This paper was focus on Dianshan River which is one of the most important water sources of Shanghai. We study the distribution, speciation and transformation rule of Cu, Cd, Cr, Hg, Pb and As in sedimentary record. In addition, the history of development of industries and agriculture were also taken into account to study the heavy metal pollution history in the study area.

本文以上海的重要水源地——淀山湖为研究对象，通过对研究区沉积物中重金属元素Cu、Cd、Cr、Hg、Pb、As的时空分布规律以及它们在沉积物中随时间或沉积深度的形态分布及迁移转化规律的研究，综合考虑区域工农业发展现状和历史对沉积物中重金属元素含量及分布的影响，对区域重金属污染历史及效应进行分析论证。

The problem of the error of calculation formula calculating the variance of grouping data within distances in statistics was put forward,and the concrete forms of correcting formula were given by the theorem of addition and the variance of even distribution.

提出统计学中的组距分组资料方差和标准差计算公式误差问题，由方差的加法定理和均匀分布方差给出分组资料方差计算和标准差计算的修正公式具体形式，并就均匀分布数列和正态分布数列组内方差平均数进行了讨论

Treating with coils as aeolotropy, this paper brings forward a set of mathematical mode for computing internal stress distribution of coil in the process of coil coiling, in which some factors are taken into account, such as the transverse distribution of shape, crown and curl tension of the strip, the friction between the strip and the reel, the friction between strips, and etc. Because the reel shrinkage and the inner circle of the strip losing radial restrain and circumferential restrain can induce interlayer slipping and the change of the whole coil compactedness , the assumption concerned ——"virtual reel" in the process of coil uncoiling is put forward, which takes the form of slow action to express the uncoiling process and, therefore clearly simulates the variation course of internal stress distribution of coil in the process of coil uncoiling.

考虑到带材板凸度、卷取张力的横向分布以及带材与卷筒之间、带材与带材之间的摩擦力等因素的影响，并将钢卷按各向异性体处理，提出一套计算卷取过程中钢卷内部应力分布的数学模型；同时考虑到卸卷过程中由于卷筒的收缩，钢卷内圈失去径向和周向约束而引起层间滑移及整个钢卷紧密程度发生变化，提出钢卷卸卷过程中有关"虚拟卷筒"假设，将卸卷过程以"慢动作"的形式表示出来，清楚地模拟出卸卷过程中钢卷内部应力分布的变化历程。

Results indicated that aphids fed on fresh bamboos by aggregately distributing, and their predators in bamboo forests were separately collected in different parts, main of which were in accord with negative binomial distribution and Polya-Eggenberger distribution, it was proved that some natural enemies in some sample sites were spraying extensively from single plot to around places, the population density of bamboo aphids was proved to be stable in a regular time.

在竹林中主要符合负二项式分布和 P-E 核心分布，为不均匀的聚集分布，存在由点片向四周扩散的现象，频次分析和聚集度指标的分析结果基本一致，其中瓢虫的聚集程度不及另外2种天敌的明显。

According to the results of the simulation, in the HTLOC process, the mixing of gas and the air can be raised with

It was based on t he Gauss distribution and conformal transformation method presented by Amari and Wu.

分析了确定数据分布特征的重要性，给出了判断数据呈高斯分布的方法，探讨了SVM核函数及其参数选择与数据分布的相关性。

Then thedistribution of the students during the period is analyzed and thealgorithm is proposed according to the size of the total students sample.Finally based on the research above, a modified dynamic probabilitydistribution algorithm is proposed to meet the the real-time and equitydemand of the course-selection system. Compared with the knownalgorithms, this algorithm can put in practice real-time course-selection.At the same time the anticipator can select the course with the sameprobability.

本文首先对已有的选课算法进行了比较研究，随后对选课人数随时间的分布进行了分析，并进行相关算法研究，按照选课样本的大小提出了相应的算法；最后综合上述算法，提出了一种改进的基于概率动态分布的选课算法思想，使得整个选课过程中，实时性与概率动态分布有了很好的结合与体现，既实现了实时选课，又能后使得参选人尽可能的拥有相等的机会(即实现选课过程中的相对公平合理性)选中某个课堂。

Cathepsin D and β-tubulin marked with fluorescence were followed in distribution observed by laser scaning microscope, the distribution was from nucleus nearby to cytoplasm and apophysis, which suggested that they took part in traffic in cells.

荧光双标组织蛋白酶D及β-tubulin，共焦激光扫描显微镜下观察，可见二者伴随分布，均由开始的核周分布明显到散在分布于胞质及突起中，说明溶酶体与骨架蛋白密切相关，提示共同参与细胞内的运输。
