针对强化学习系统学习速度较慢的问题，提出了提高强化学习速度的5种方法，即输入空间的量化方法、采用局部逼近神经网络实现强化学习系统方法、采用强化学习综合学习算法和利用动作模型及先验知识等方法，通过仿真实验验证了所提出方法的有效性。

A reverse measurement system about the data collecting of 2-D object edge based on machine vision is discussed,in order to realize digital data input of the dimensions of 2-D object complex edge. This system realized calibration in large scene by virtual grid calibration method, and advanced the precision of system by using double CCD cameras. It realized data mergence by setting up referencer of regular shape. Some methods were put forward to realize graphics vectorization such as using eight-chain code difference to search for the turning points, and using change-length subjunctive beeline to distinguish linetype. The output data use the general DXF document format to connect the software of CAD. Research indicated that this system can be applied in reverse measurement to the dimensions of 2-D object complex edge.

对机器视觉二维反求测量系统进行了研究，以实现二维复杂平面边缘尺寸的数字化录入；采用虚拟网格技术实现大场景下的测量标定；利用双CCD分区域获取图象，通过设置规则参照物、数据拼接等数据处理提高测量精度；提出了利用8-链码的&链差&确定转折点，用&变长度虚拟直线&判断线型实现图形矢量化的方法；数据输出采用通用的DXF文件格式实现与CAD软件的接口；研究结果表明，该系统能够应用于二维复杂平面边缘的反求测量。

The difference is that "Correspondence" asa theory is put forward by Baudelaire, which is a theory of philosophy-aesthetics, while "Symbol" as an ism is expressed by Verlaine, Rimbaud and Mallarme after Baudelair, which is a doctrine reduced to a practical level.

其区别在于，前者由波德莱尔提出，而后者是波德莱尔去世后由魏尔伦、兰波和马拉美等所表征出来的；前者是一种哲学美学理论，而后者是一种下降到可操作层面的&主义&。

The form discussion studies Liang Zongdai and Ye Gongchao respectively introduced and spreaded the French imagism and British and American formalism. The Poem special issue in the literature and art supplement of Ta kung Pao Newspaper and New Poetry organized twice discussions in poetic forms. The pure poetry school introduced that the modernists introduced the western and ancient pure poetry theories: from Baudelaire, Mallarme, Vale'ry, H. Read, A. Bremond to J.M. Murray, and the basic idea and difference of pure poetry. Besides, a lot of modem poets became greatly interested in pursuit heat of the pure poetry in late Tang and Nan Song dynasties, studying the development and variation of pure poetry. Music theory argues that modernists make introduction and reform on the western and Chinese music theory. He Qifang and Bian Zhilin continue the topic to the contemporary time, and put forward the theoretical frames in Chinese poetry. Rhyme and rhythm theory make researches on the introduction and reform of French symbolism and British and American modernists' rhyme and rhythm theory, making studies on the Chinese new form poetry and its thyme and rhythm theory.
