Fingerprints of broiler chickens divergently selected for very low den sity lipoprotein in fat line and lean line of the third generation were studied using inter simple sequence repeated technique. Geneti c polymorphism and genetic similarity coefficient between two groups were analyze d. Ten primers were screened from 60 SSR primers and 62 sites were deprived. Of which 39 bands were polymorphic sites and the frequency was 63 percent.

选取属级分类单元作为统计变量， Dice系数作为统计公式，对中国早中侏罗世较具代表性的18个植物群进行了相似性的聚类分析。

Four important conclusions were drawn. First, the CMLE method is the most suitable pro-cedure for parameter estimation in 1-parameter model. Second, the test construction of TIPS guided by classical test theory will not be valid for obtaining reliable measures. Third, the systemmatic ICC presenting method presented the perfect item and ability latent traits for the results in CMLE findings. Fourth, the complicated analysis of reliability coefficient and likeli-hood parameters met the precise and accurate measures of latent traits in either integrated process skills or hypothesizing skills.

本研究四项主要结论如下：一是CMLE确为分析试题潜在结构的量化模式，本文之精心分析过程及分析技术本身即为重要的测验资料分析规范；二是TIPS全卷及试题与原始之评量目标对应关系并未如古典测验理论之分析结果；三是各试题之表徵曲线图示法，显示在同一难易度鉴别度下，CMLE估计法分析确实显现高、中、低能力群之试题及能力特质；四是由信度系数及概度参数分析精准地显示了全卷及形成假说技能之试题参数之潜在特质。
