In this paper, we studied community stability, forage quality and yield character about the mixed-sowing of Medicago sativa and Bromus intermis from 2003 to 2004 and using Factor Analysis, Principal Components Analysis methods and getting the yield forecast model with linear regress multianalysis method. The study provided theoretical foundation for establishing high yield and good quality artifical pasture.

本试验以紫花苜蓿与无芒雀麦为供试材料，于 2003~2004 年对 6 个不同混播处理的群落稳定性、牧草产量及质量性状进行了系统的研究，并运用因子分析法、主成分分析法和多元线性回归的方法，建立了产量预测预报模型，结合经济效益评价和提高土壤肥力的因素，确立最佳混播处理。

After Confirmative Factor Analysis, Regression Analysis, and Structural Equation Modeling, I summarized main conclusions as follow. First, rule legitimacy and organizational identification have different effects on different rule behaviors.

对数据采用验证性因素分析、回归分析和结构方程模型分析，得到以下结论：第一，对于不同的规则行为，个体对规则的合法性判断和组织认同的作用机制是不同的。

Based on data of Yanhe river basin's hydrological stations on precipitation, runoff, soil and water conservation measure area sizes (terrace land, forestation land, grassed land, and silted dam land) from 1950s'-1980s', the basin's monthly precipitation station weightiness indexes and the four main measure areas weightiness indexes through correlation analysis and factor analysis were built.

以建立一种科学的较简单的评价方法为目的，以延河流域水文站20世纪50-80年代30余年降水、径流、水土保持主体措施面积(梯田、造林、种草、淤堤坝)资料为基础，运用相关分析、因子分析等方法，建立了流域雨量站各月降雨量权重指标体系、流域4大水土保持措施面积权重指标值，并构建了以水土保持面积指标、降雨量指标为参数的流域水文响应评价模型，进而分析水土保持措施对流域径流量的效应。

Percent and 21. 4 percent respectively. F1 plants of R01 self-cross also present diverse colors such as white, pink, red, nacarat/saffron, dark yellow, yellow and so on, And the pink and the nacarat/saffron plants have the highest proportions, 50.6 percent and 31. 4 percent, respectively. The wide segregation chromatogram of self-cross progeny implies that these two varieties themselves contain the abundant genetic polymorphism. The ISSR genetic diversity analysis and the principle factor analysis were performed using 49 plants of RP1 self-cross progeny population and 123 plants of R01 self-cross progeny population.

RP1及R01的遗传多样性最高，这从自交一代的表观性状及ISSR的遗传变异可以得到证实，如RP1自交，F1代花色有白色、粉色、玫瑰红、深红色、桔红/桔黄、黄色，黄红复色等，其中以粉色及桔红/桔黄色占的比例最大（分别占61.2％，21.4％）；R01自交，Fl代花色有白色、粉色、红色、桔红//桔黄、深黄色，黄色，其中以粉色及桔红/桔黄色占的比例最大（分别占50.6％，31.4％），较广的自交分离色谱，表明两个品系自身存在丰富的遗传多态性。

Factor analysis was employed to reduce the number of parameters deduced from multiple radiometric methods. The derived principal components f1, f2 are undependent with each other and of identified geological means. The trend analysis on f1 and f2 was conducted to extract the remainder anomalies which reflect the radioactivity elements enrichment formed by fracture structures and locate the spatial positions of thermal underground water.

对于由多种放射性方法造成的多参数，采用了因子分析方法以降低参数量，组成互不干扰而地质意义明确的主成份分量f1、f2，继而对f1、f2进行趋势分析，提取了由构造断裂造成的的放射性元素富集的剩余异常，圈定出地下热储的空间位置。

The results shown that both [Cu_2]~2+ and NR molecular can intercalates into the DNA double helix layer, and there is a competition between these two interactions. Furthermore, chemometrics approach, parallel factor analysis, was used to resolve the measured three-way CW-SFS data, which provided simultaneously the concentration information for the three reaction components, NR, [Cu_2]~2+ and NR-DNA, for the system at each equilibrium point. This PARAFAC analysis indicated that the intercalation of the [Cu_2]~2+ molecule into the DNA proceeds by exchanging with the NR probe, and can be attributed to two parallel reactions.
