For the coordination of multiple agents in noncooperation environment, we considered the learning aim as finding a Nash equilibrium strategy through in learning function taking other agent's actions into account. Therefore, we expended the single agent Q-learning algorithm into multiagent Q-learning algorithm. In addition, we proved the convergence of multi-agent Q-learning algorithm under certain general sum stochastic game architecture for only one Nash equilibrium or multiple same Nash equilibrium.

对于非合作环境下的多智能体协调我们通过在学习函数中考虑了智能体的联合行动，提出把学习目标作为求取一个Nash平衡点策略，这样将单智能体Q-learning算法扩展到多智能体的Q-learning算法；证明了在一定的一般和随机对策结构下具有一个或多个相同Nash平衡点条件下多智能体Q-learning算法的收敛性。

In the present experiment, the screening techniques for salt tolerance and mutants of strawberry leaf and anther callus in vitro were studied, and primary screening system for salt tolerance evaluation was established. It was studied the sensitivity to mutagen of different strawberry cultivars and different tissues in vitro.

本试验以草莓离体叶片及花药愈伤组织为试材进行了耐盐突变体的诱变及筛选研究，初步建立了草莓耐盐突变体诱变筛选的技术体系，研究了草莓品种以及离体组织对诱变剂的敏感性，并且对不同诱变处理再生植株的耐盐性差异进行了比较。

Main sandstone is subaquatic distributary channel sandstone, and microelectrode curve is box distribution function.

榆树林油田处于松辽盆地北部中央坳陷区三肇凹陷东部斜坡，主要产油层系是中生界白垩系泉三、四段的扶余、杨大城子油层，储层为河流相沉积，主要砂体为有底钙存在的正旋回河道砂体，微电极曲线形态为箱型；其次为姚一段的葡萄花油层，储层为三角洲内前缘沉积，主要砂体为水下分流河道砂体，微电极曲线形态为箱型。

There are two kinds of spinels in a granulite terrain of Yushujgou, South Tianshan Mountain. One occurs in the intermediate and basic granulite units and is characterized by enriched Al and poor Cr, belonging to Al_spinel. In thin sections it shows dark green color and subhedral to anhedral form, and coexists with other metamorphic minerals, suggesting a neogenic metamorphic mineral of granulite facies. The other occurs in the adjacent ultramafic rock unit, belonging to Cr_spinel. In thin sections, it is dark brown in color and is scattered among olivine, clinopyroxene and orthopyroxene as irregular grains, indicating a stable residual mineral in the process of granulite facies metamorphism.
