It is interpreted that the correlation structure of the allelic polymorphism data contains null correlations introduced by "closure" and the statistical distribution of the data is not normal because of its constant row sum,which resulted in great difficulties in analyzing the data with traditional multiple linear statistical methods such as principal component analysis,factor analysis,cluster analysis and canonical correlation analysis.

长期以来，对于多维基因多态性数据的多元统计分析，如计算遗传距离时所用的聚类分析、分析群体遗传结构时所用的主成分分析、因子分析和典型相关分析等，一直应用为无约束条件数据而设计的经典多元线性分析方法，并没有注意基因多态性数据的"闭合效应"所带来的问题。

Probably the most common need for a custom datasource is when dealing with a large amount of external data (for which you already have an interface) that can retrieve data based on a col and row vector, obviating the overhead that would be required in duplicating data items by preloading them through the SetCell interface of the grid.

Rough集理论[1-3]自1982年由波兰数学家Pawlak Z教授提出以来，经过20多年的研究和发展，在系统理论、计算机模型的建立和应用系统的研制开发上，已经取得了许多成果，也建立了一套完整的Rough集理论体系，特别是由于上世纪80年代末和90年代初在知识发现等领域得到成功的应用而受到国际上广泛关注。

The obtained spatial data are comparatively incompleteness, and it is necessary for the observed data to radiate their data energies from the sample space to their parent space.

空间数据挖掘面对的首先是空间观测数据，然后才形成概念；先有连续的数据量，然后才有离散的符号量。

The article studied and analyzed the data of the investigative fishing vessel from 2002 to 2005, fisheries statistical data of Zhoushan and sequential monitoring data of Mackerel and Scad from marine fisheries research institute of Zhejiang Province. The results showed that the fishing ground of Mackerel and Scad mainly distributed in 28°-32°N, 122°-125°E, and fishing period was usually July to September, yearly average ratio of Mackerel and scad was 98.97 % from 2002 to 2005. According to the early rearch result of others, the fishery resources of Mackerel and Scad are 120 thousand tons.

对灯光围网调查船2002~2005年的渔业生产调查资料、舟山市渔业统计资料和浙江省海洋水产研究所历年来的上层鱼监测资料进行了研究和分析，结果表明：2002~2005年，浙江省群众灯光围网渔业的作业渔场主要集中在28°~32°N、122°~125°E之间的海域，渔期一般为每年的7~9月；鲐鲹鱼占总渔获的年均比例为98.97%；根据历史资料粗略推算，调查海域鲐鲹鱼等中上层鱼类的资源量约为12×10^4t，最大持续产量为5.8~6.7t，最佳捕捞船数315组左右。
