The phytoplasmas diseases were investigated in 30 counties and cities of 10 areas in Yunnan Province. There are 12 phytoplasma diseases, including paulownia witches-broom,chinaberry witches-broom, cactus witches-broom, christmas cactus witches-broom, orange little leaf, petunia flat stem and so on were indentified using PCR with universal primers, which amplified phytoplasma 16SrRNA gene and/or ribosomal protein genes. So the kind of phytoplasma diseases in Yunnnan Province were understood. Identified the characteristic of 16SrRNA and rp gene of phytoplasma and the kind, classification and genitic relativity of these strains using RFLP, clonging and sequence analysis (nearly 20 full-length sequences of phytoplasma 16SrRNA and/or rp gene were submitted in GenBank ); The phytoplasma strains isolated from herbage plants were conserved in storeroom. 9 articles were published in the key journals of China and 1 technique invention patent was applied. The net-page about phytoplasma disease was established. 4 graduate student were bringed up.

对云南省10个地区的30余个县市地区进行了植原体病害的调查采集工作；采用植原体16SrRNA基因通用引物（R16mF2/R16mR1及R16F2/R16R2）和/或植原体核糖体蛋白基因引物（rpF1/R1）对所采集到的病害标样总DNA进行PCR扩增，根据植原体特异扩增条带的出现，共鉴定出泡桐丛枝、苦楝丛枝、仙人掌丛枝、蟹爪兰丛枝、柑桔小叶、矮牵牛扁茎等12种植原体病害，初步明确了云南省植原体病害的种类；通过RFLP技术、克隆及测序技术获得其16SrRNA及部分核糖体蛋白基因的近全长序列（已在GenBank中共登录近20余个相关序列），通过序列比较分析，明确了上述植原体株系中这两个基因的特征并确定了云南省植原体株系的种类、分类地位及遗传相关性；对一些发生在草本植物上的植原体进行了株系保存；在国内核心期刊及一般期刊发表研究论文 9 篇，申请技术发明专利1项；初步建立了有关植原体病害的网页；培养研究生4名。

It is suggested that it is better to indicate the variability within breeds by average heterozygosity based on microsatellite polymorphisms, which showed high polymorphisms and codominant inheritance of the markers, where as differences between populations and even specific characteristics with in a population are reffected clearly and directly by RAPD.

由于微卫星标记多态性程度高且等显性遗传，因而通过它计算杂合度可以较好地反映群体内的变异；RAPD则在反映群体间的区别甚至某一群体的特征时可提供明确而直接的信息。

Depending on getting the crossway transportation data, the intention of the study is to make use of the expert system, neural network and genetic algorithm to analyze the dynamic characteristic of transportation and to form the global optimization control order, and to realize the local signal lamp control by the method of utilization fuzzy control.

研究的目标是在交通数据采集的基础上利用专家系统、神经网络、遗传算法等技术分析交通动态特征、形成全局优化调度指令，并利用模糊控制的方法实现交叉口的信号灯控制。

The use of genetically engineered murine models of heart failure has proven valuable in characterizing the progression of remodeling and its ultimate decompensation to failure.

应用遗传设计的心衰鼠模型已证明对表现重构进展和它的终末失代偿到衰竭期的特征有价值。

First, select four kinds of main risks source from bigly celebrate the main risk in region source, namely the flood, drought, sand-dust weather and petroleum pollution accident, etc. According to the different a request for to habitat, study this 19 kinds of landscapes ecosystem type of the Regional induce for 7 kinds of ecosystems system: Then the marsh of bulrush, lakes and reservoirs , salt alkali wasteland, prairie, island form wood, farmland, town. The difference is proceeded by characteristic according to each type ecosystem to the analysis of four kinds of main risks source, including the certain risk all rate, delimiting the space distribute, analyzing the risk strength to the receptor etc. At proceed the revelation the different from endanger to analyze the inside, this text borrows ecosystem index number that this index sign to reflect primarily habitat the ecosystem meaning of the type of habitat the different from position, with weak an index number to show the destructibility of the habitat, from but compute each ecosystem that is lost by ecosystem system an index number.

首先，从大庆地区主要的风险源中遴选出四种主要的风险源，即洪涝、干旱、沙尘天气和石油污染等；依据不同生物类群对生境的要求，将本研究区域的19种景观生态类型归纳为7种生态系统：即芦苇沼泽、湖泡库渠、盐碱荒地、草甸草原、岛状林、农田、城镇；对四种主要风险源的进行分析，包括确定风险概率，划定空间分布，对风险受体的作用强度分析等；在进行暴露和危害分析中，本文主要借生态指数这一指标来反映不同生境类型的生态意义和地位，以脆弱度指数来体现不同生境的易损性，从而计算出各受体生态系统的生态损失度指数；由于各主要风险物质对风险受体的作用强度是不同的，对形成区域性生态风险的作用大小也有差异，因此本文采用层次分析法对主要生态风险物质进行综合评价，并把判断矩阵排序权值的合理计算问题归为—非线性化问题，并提出用基于遗传算法(GA[5])的层次分析模型进行权重分析；进行风险表征，即综合前面两个阶段的信息，对环境中风险的性质和强度以及风险评价过程中不确定性问题进行分析与描述，并划分出五级生态风险区；最后，根据划分的五级生态风险区的特征，分别提出针对各生态风险区的生态风险管理对策。
