广东省“2000年人人享有卫生保健”成果分指标分析

文章对广东省 115个有农村初保任务的县 (市、区 )进行了一次针对省级审评结果的分指标分析 ,结果表明 ,全省初保审评平均总得分为 85 .43± 5 .7。115个县级单位中有 94个达标 ,余 2 1个为基本达标。从指标的得分情况看 ,各大项指标的得分率均超过标准分值的 6 0 % ,得分率超过标准分值 70 %以上的指标数占总指标数的 90 .7%。从 12项大指标 33项分指标的进一步分析表明 ,大多数分指标的完成率较高 ,表明广东省农村初级卫生保健工作已取得显著的成效。全面分析也发现 ,有少数分指标在少数县级单位的得分率还比较低 ,甚至有零的现象 ,事实说明农村初级卫生保健是一项十分艰巨的工作 ,要取得圆满的答案 。

分层次多指标综合分析法筛选废水优控污染物——以江苏某沿江化工园区为例

化工行业覆盖面广,排放污染物多,简单以COD、氨氮等常规污染物为指标评估废水排放达标情况并不能准确反应真实情况。为精准地评估废水排放达标情况,需要确立优控特征污染物指标。以江苏省某沿江化工园区为例,通过分层次多指标综合分析的方法,在筛选出园区内企业废水优控特征污染物的基础上,以企业排放量、污染物当量、企业数量、环境质量标准和致癌性5个指标分别对有机污染物、无机重金属和综合性污染物指标进行赋值,对各特征污染物总赋值进行排序,筛选得出园区废水优控特征污染物为苯乙烯、甲苯、甲醛、总镍、氟化物。结合该化工园区开展的地下水环境状况调查结果,将砷、锑两项特征污染物一并纳入优控特征污染物的管控。优控特征污染物的筛选可为化工园区污染防治提供更精准的方向和更科学的决策依据。

Genetic Diversity Analysis and Fingerprint Construction of Major Mango Cultivars in China

[Objective] The genetic diversity of major mango cultivars in China was analyzed by using SSR markers, and their fingerprints were constructed so as to provide theoretical basis for germplasm innovation and breeding of mango. [Method] With 115 pairs of SSR primers, genetic diversity analysis and cluster analysis were performed for 30 mango cultivars, among which the genetic relationships were analyzed. [Result] Total 64 pairs of polymorphic primers were screened out from the 115 pairs of primers, and total 343 bands were amplified from the 30 cultivars with 73.2% of polymorphic bands. On average, 3.9 allelic loci were detected for each pair of primers with genetic diversity index of 0.5, Shannon＇s diversity index of 1.00 and polymorphism information content of 0.49, indicating higher genetic diversity. The cluster analysis showed that the 30 major cultivars could be classified into four categories. The first category included 14 cultivars; the second category included 11 cultivars, most of which were introduced from abroad; the third category included 4 cultivars, Le., Miansan, Parayinda, Baiyu and Hongxiangya： the fourth category included only one cultivar Maqiesu.By using 7 pairs of SSR markers, i.e., M42, M49, M54, M55, M96, M99 and M103, digital fingerprints were constructed for the 30 mango cultivars. [Conclusion] The 30 mango cultivars present more complex genomic genetics and abundant genetic information, and they have higher genetic diversity.

Bayesian and Multiple Bayesian Analysis of the Reliability Performances for Series System with Cold Standby Units

By using Bayesian and multiple Bayesian method, the failure probability, reliability and mean time to failure(MTTF) of series system with cold standby units are estimated. At last, we compare the two estimators by means of Monte_Carlo simulation.

Evaluation of the Rural Human Settlement in Shandong Province

Taking Shandong Province as the research object,this paper uses the principal component analysis method to evaluate the status of the rural human settlement in Shandong Province.It establishes the evaluation index system of the rural residential environment in Shandong Province,including living environment,economy,infrastructure,public service facilities,and ecological environment,in total five comprehensive index,and 20 secondary indexes.Through measurement and sorting of rural human environment development level of Shandong Province in 2010,the 17 cities are divided into-excellent,good,ordinary,poor-four development areas and are analyzed based on the restriction factor in the development of the region.

Optimization Analysis on Comprehensive Evaluation Index of Wetland Parks

Wetland park is an important mode of wetland protection, meanwhile, construction of comprehensive index system has become the hotspot and keystone of the researches on Wetland Parks. Basing on different development stages, this paper firstly divided the Wetland Parks into three categories, including the start-up stage, the development stage and the refinement stage. And then screened and identified the direction and keypoints of comprehensive evaluation for wetland parks in different development stages using expert scoring, questionnaire and analytic hierarchy process(AHP).

Partner selection of collaborative innovation of strategic emerging industry - based on ANP-GRA

The rise and development of strategic emerging industries need a new innovative mode--collaborative innovation, collaborative innovation as a complex multi-object relationship, it is essential to select an appropriate partner. Partner selection is the key to the success of strategic emerging industry collaborative innovation. This paper takes collaborative innovation partner selection as research focus, establishing evaluation system of collaborative innovation partner selection, using analytic network process （ANP） to determine the weight of evaluation index, then, obtaining grey correlation rank of collaborative innovation partner by Grey relational analysis （GILA）, providing the basis for strategic emerging industry to select collaborative innovation partner.
