The basic principle and algorithm of Q-learning and related developed algorithms including Q and SARSA is studied. We distinguished between two types of RL algorithms: on-policy and off-policy, and the convergence result of SARSA(0) algorithm was discussed.

研究了Q-学习的基本原理、算法和相关的几种改进算法，如Q算法和SARSA算法；区分了两类强化学习算法：在策略和离策略算法；讨论了SARSA(0)算法的收敛性。

另一方面，有基本金属、电气设备和家电、造纸、纺织、皮革、印刷、橡胶和塑料、饮料和烟草行业组成的工业大类的产能则下降了0.9%。

And capacity in another industrial subaggregate - including primary metals, electrical equipment and appliances, paper, textiles, leather, printing, rubber and plastics, and beverages and tobacco - has contracted by a whopping 2% over the past year.

同期之中，由基本金属、电气设备和家电、造纸、纺织、皮革、印刷、橡胶和塑料、饮料和烟草组成的工业大类的产能更是下降了整整2%。

In the late Turolian ( MN12, MN13 ) European and southern Chinese suid lineages appeared for the first time in northern China.

晚中新世中期late Vallesian(MN10 and early Turolian(MN11)，中国和欧洲的猪类与南亚已基本没有交流，在各自地区相对独立地演化发展。

RESULTS: During 10 - 12 weeks, in cuntrol group: The defect area was repaired by white and soft tissue that had no resistance to press. The repaired tissue was still lower than the surrounding articular surface with clear boundary. By histological observation, it was found that the defect was repaired by the mechanism similar to inflammatory reaction and the defect is ultimately filled by the hyperplasia of hyaline degenerative fibrous tissues. In filling group: the defect was repaired by semi-transparent, smooth, textured tissues with polish that had resistance to press as well as elasticity. The repaired tissue was almost similar to the shape of the surrounding cartilage,difficult to be distinguished. After histological observation, it was found that there was no inflammatory reaction, but active hyperplasia of inner bonetissue and cartilage tissues; a lot of osteoid tissues and trabeculation were found. Newlborn cartilage was fused with surrounding cartilage tissue and connected with surrounding tissues.

结果：10～12周，对照组：缺损区由白色、质软、按压无阻抗的组织修复，修复组织仍低于周围关节面，边界仍清晰可辨，组织学以类似炎症反应的机制修复缺损，最终以透明变性的纤维组织的增生来填补缺损部位；填充组：缺损区由半透明状、质韧光滑有光泽，按压有阻抗并有弹性的组织修复，修复组织与周围软骨外形上已基本相似，不易区分，组织学未见有炎症反应的过程，内骨组织和软骨组织增生活跃，并可见大量类骨组织和骨小梁形成，新生软骨和周围软骨组织融合，并与周围组织连接。

通过对欧利坨子原油地球化学特征的研究，发现原油性质的差异同储集层与火山口的相对位置有着密切的关系，在火山口附近的粗面岩储集层中，原油的饱和烃及其单体碳同位素值偏轻，类异戊二烯烃的碳同位素负异常基本消失，原油的CPI和OEP值较低(平均为1·21和1·06)。

Triphenylamine and their derivatives are excellent optical materials,and TPA is chosen as the basic framework for the design and synthesis of a series of TPA-based dyes.

三苯胺(Triphenylamine，TPA)及其衍生物是一类性能优良的光电材料，本论文即是选用三苯胺为基本骨架，通过简单的有机反应，设计和合成一系列三苯胺类有机敏化剂。

The first chapter introduces the equilibrium and disequilibrium theory which is the principal economic theory in west, analyses Disequilibram theory's unactuality and its existact value in theory, establishes the basis view which uses anterwalras'disequilibrium Theory as researching object, especially introduces li yiling's two Disequilibrum Economy Theories.

第一章介绍了西方主要的均衡与非均衡理论，分析了均衡理论的非现实性及其存在的理论价值，确立了将反瓦尔拉斯非均衡理论做为研究对象的基本视角，并依据中国当前的经济现实，着重介绍了厉以宁的两类经济非均衡理论。
