For situations of self-rational agents, Inter-Multi-Agent-Contract was formulated to describe the negotiation status of distributed planning and scheduling. Monotonously increasing voidance and violence penalties were defined to facilitate reciprocal cooperation. Negotiation protocol was designed based on bidding and bargaining theory. Commitment mechanism that permits non-immediately effective commitments and enforces monotonously increasing voidance penalty was defined to promote the efficiency of negotiation.

Coal-bearing seams in Shenyu mine area inclines northwest, the bedrock thickness on the coal seams increases northwest, and there are generally red soil water-resisting layer on the bedrock. To study on the coal-water friendly geological conditions for the water-resisting layer during the coal mining process, and to determine mining zones without causing obvious water table decline are an important approach to the water-conserving mining in the fragile ecological mine area of North Shaanxi.

榆神矿区含煤地层整体向北西倾斜，煤层上覆基岩厚度向北西方向增大，基岩之上普遍分布有红土隔水层，深入研究煤炭开采过程中不对含水层造成破坏的煤水共生地质条件，确定既可采煤、又可实现水位不明显下降的区域，是陕北生态脆弱矿区保水开采的重要途径。

All the analysis was done using SAS EM 4.1 software. The prevalence of tracheobronchitis were higher in spring and autumn. Average atmospheric pressure, average temperature, highest air temperature, lowest air temperature, water-vapour pressure, degradation of visibility were positively correlated with the prevalence of tracheobronchitis. Factors that affected the incidence of tracheobronchitis were average atmospheric pressure, degradation of visibility, daily temperature difference and water-vapour pressure.

结果］湖州市气管支气管炎门诊人数存在明显的季节分布差异，夏季和冬季是此类疾病的2个高发季节，而春季和秋季门诊人数较少；其门诊人数与平均气压、平均气温、最高气温、最低气温、水汽压、大气能见度等气象条件存在较好相关性；影响气管支气管炎门诊人数的主要气象因子有平均气压、能见度、日较差和水汽压，当平均气压≥1020.33hPa且能见度＜6.2km时，气管支气管炎门诊人数最高。

First of all,we tested the germination and water uptake rate of 47 species typical xerophil seeds grow up in north China from 20 families,38 genuses under sufficient water and different Grads water stress by high-molecular-weight polyethylene glycol(PEG6000).The results show that Xerophil seeds from the same habitat exhibited similar patterns in response to water stress.Xerophil seeds from arid community were stronger in germination and imbibition than that from other two communities under serious water stress,whereas Xerophil seeds from humid community were sensitive to any degree of water stress.Namely,the seeds live in arid habitat possessed high germination and quickly water uptake in sufficient water or any degree of water stress,but the others grow up in humid habitat shown significant difference which germination and water uptake well under sufficient water but inhibited even if slight water stress.

首先，我们通过对20个科，38属，47种旱生植物种子在水分充足和不同梯度的干旱处理(聚乙二醇PEG6000)条件下的萌发率及吸水率实验发现，当水分胁迫强烈时，分布于干旱沙漠地区的植物种子其吸水率和萌发率都高于半干旱和湿润地区的植物群落，相反，湿润地区植物种子的吸水率和萌发率对任何的水分胁迫都表现出敏感的响应趋势，也就是说，生境恶劣的植物种子在较强的干旱胁迫下，仍然保持了较高较快的萌发率及吸水率，水分充足与水分缺乏时无显著差异，而生境相对较好的植物种子在水分充足情况下萌发与吸水良好，但在干旱胁迫时则受到明显抑制，水分充足与水分缺乏时差异显著。

The morphological and anatomical features of Quercus Section Suber,the dominant species of the sclerophyllous evergreen broad leaved-forest,from different habitats were compared The results show that Quercus Section Suber possesses dual morphological characteristics of non-succulent xerophyte and al-pine plants.

对分布在不同生态环境条件下的硬叶常绿阔叶林建群种高山栎组植物叶的形态解剖特征进行了比较研究。

Endangered Abies yuanbaoshanensis will probably have been extinct,so it very necessary to studying its genetic diversity with a proper way in order to save this key group of biological diversity in China.In the present study,AFLP(amplified fragment length polymorphism) markers was used to examine population of Abies yuanbaoshanensis in order to understand the level of population genetic variation and genetic structure.

首先，物种的遗传多样性是长期进化的结果，是其生存和发展的前提，对遗传多样性进行研究可以为分析濒危物种或种群的进化潜力和未来命运提供重要资料；其次，遗传多样性是保护生物学研究的核心之一，不了解种内遗传变异大小、时空分布及其与环境条件的关系，就无法采用科学有效的措施来挽救濒于灭绝的物种、保护受到威胁的物种，对珍惜濒危物种制定合理的保护方针和策略，有赖于对物种遗传多样性的认识。
