Management and Improvement of Urban Grassroots Cultural Market--Taking Internet Cafes And Entertainment Siming As An Example

文化市场，作为社会主义市场经济中的重要的组成部分之一，已经发展为厦门市经济的支柱产业之一。随着文化市场的发展越来越多样化，我国学者对文化市场管理也进行了探索研究，认为在文化市场管理上还存在体制，法制建设，人员配置，管理模式等四个方面的问题，但对基层文化市场综合执法的关注较少。本文为弥补这一不足，对基层文化市场执法中存在的问题进行了分析和探索，为进一步优化文化市场管理提供依据，以维护良好的文化市场环境。 本文采用文献综述法、调查问卷法和访谈法，重点对厦门市思明区文化市场的管理现状进行调查研究，总结存在的问题，并探讨改进的对策。厦门市2005年形成了独立的文化市场综合执法部门，实现了“管办分离”...Culture is an accumulation of social history, but also an innovation. With the expansion of social division of labor, production of private ownership, the emergence of barter, gradually the cultural market has been formed. Cultural market is an important component of the socialist economy market. It has developed into one of the pillar industries in Xiamen City economy.

A Water-saving Device for Solar-powered Water Heater

介绍一种用于热水器的节水装置的工作原理,该装置由温度检测系统、PlC控制系统及执行机构(电磁阀)等三部分组成。其节水的功能在于,当用户需要使用热水时,启动节水装置开关,系统自动检测并将原本储存在热水器与水龙头之间的冷水泵回主水管道,直至热水到达出水口时恢复普通使用状态,从而避免将大量冷水放流而造成的水资源浪费。The principle of work of a water-saving device for the solar-powered water heater is presented.The device is made up of three parts: the temperature examination module,the PLC control module and the executive module(two solenoid valves).The saving water process of this device is as follows: when the user needs to use the hot water,open the switch of the device,then the device will make the cold water which between the hot water tank and the tap back to the main pipeline until the hot water gets to the tap.Then the user can use the hot water normally.In this way,lots of water waste can be avoided

Synthesis and Crystal Structure of a Novel Self-assembled1,4-dimethyl Cucurbituril Silver(I) Complex

Crystals of a new 1,4-dimethyl cucurbituril(TMeQ6) with Silver(I) ion were synthesized, and the structure was determined by X-ray diffraction technique. There are two kinds of TMeQ6 A and B which formed molecular encapsulates with two silver ion lids in the self-assembled entities. One dimensional supramolecular tubes are formed from the encapsulates A, and two dimensional molecular sieves are formed from the encapsulates B, the tubes and the sieves stack together alternately in the self-assembled entities.

分别用核磁共振、紫外可见吸收和X射线单晶衍射方法研究对称四甲基六元瓜环与2-氨基甲基吡啶的相互作用及其结构特征.1HNMR谱图和紫外可见吸收光谱图清晰表明,2-氨基甲基吡啶与对称四甲基六元瓜环有明显的相互作用,客体2-氨基甲基吡啶的吡啶环部分进入了瓜环空腔,1HNMR谱图相关质子峰的积分强度以及客体吸光度随主体瓜环浓度变化明确表示它们之间形成了1∶1的包结配合物,此包结比并不随瓜环的浓度增加而改变.X射线单晶衍射法对包结配合物晶体的测定进一步证实了核磁共振、紫外可见吸收方法所得结论.Interaction and structure of a host-guest inclusion complex of symmetrical tetramethyl substi- tuted cucurbit[6]uril (TMeQ[6]) with 2-(aminomethyl)pyridine (amp) have been studied by using 1H NMR technique, UV-visible spectrophotometry and single crystal X-ray diffraction determination. The experimen- tal results from 1H NMR and UV-visible spectra revealed that the amp as a guest enters into the cavity of TMeQ[6] to form a host-guest inclusion complex of TMeQ[6] and amp with a constant ratio of 1∶1. The single crystal X-ray diffraction determination further confirmed the conclusions.国家自然科学基金(Nos.200261002,20362003);; 科技部国际科技合作重点计划(No.2003DF000030);; 贵州省省长资金;; 贵州省教育厅自然科学研究资助项目
