热电偶定标实验误差研究

热电偶是一种常用的温度传感器。它是基于热电效应,将热信号转换成电信号进行传递,从而达到远距离测温。热电偶在使用前必须进行定标,确定温差电动势与温度之间的对应关系,确定温差电偶常数α。本文介绍了比较法对热电偶定标的原理及实验结果,并对实验可能产生的误差做出分析。

知识组织图书馆知识转移影响因素的建模研究

图书馆知识转移的影响因素可以归纳为知识因素与非知识因素共同作用的结果。各因素相互制约,相互渗透,影响着图书馆知识转移的效果,决定图书馆知识转移的方向和水平。图书馆知识转移的影响因素模型采用层次分析法,通过分析影响图书馆知识转移的主要因子之间的相互作用关系,构造成对比较矩阵,有效避免不同级别因素间的交叉影响,建立各个因素对图书馆知识转移影响的数学模型。     

经络兴奋疗法提高运动能力的研究

为了寻找更好的针刺疗法，将32只大鼠分为4组，分别给予经皮电刺激、电刺激十针刺、药物经皮导入＋针刺，或不作特殊处理。在我们自行研制的大鼠游泳输出功测量仪上每隔4d对大白鼠进行一次游泳衰竭训练，并测定其作功能力。每次训练后针刺加经络导入泥瓦林，则运动能力的提高显著高于单纯电针或无处理组，表明药物兴奋经络全并针刺的确可以加强经络系统对机体的治疗作用和调整作用，提出针刺兴奋经络可促进机体对运动训练产生适应。     

福建张圣君信仰文化与地方旅游业的开发建设

张圣君是宋代闽中地区平民社会中产生的民间信仰神祗。其信仰历史悠久,流行闽台至今,具有深厚的社会基础和顽强的生命力。从明代开始,张圣君信仰及其传说故事就与各地的地方风物传说密切结合。文化旅游带来的可观的经济效益成为政府日趋关注的焦点。张圣君信仰的物质载体一历史悠久的庙宇及其光怪陆离、五彩斑斓的神话传说也成为政府开发地方旅游业的重要契机。张圣君信仰文化在提升地方旅游业的知名度中扮演着越来越重要的角色。如果将全省张圣君信仰文化资源加以整合利用,并选择良好的可持续的开发、发展模式,张圣君文化旅游定能焕发异彩。

共生理论嵌入乡村旅游生态系统创新研究

How to realize the innovation of rural tourism ecosystem has always been a dual problem in both the theoretical research and practical exploration of the anti-poverty project in rural tourism. The theory of symbiosis has become one of the main approaches to solve the problem of rural poverty in China. However, the existing research on how the symbiosis theory is embedded into and how it affects the ecosystem innovation of rural tourism is still insufficient. Based on the analysis of the questionnaire on the innovation of rural tourism ecosystem, this paper describes the mechanism of embedding the symbiosis theory into the innovation of rural tourism ecosystem from the two symbiosis units of supply and demand, and answers the relevant issues of "how the symbiosis theory embeds into and affects the innovation of rural tourism ecosystem".  This is a new perspective, an extension and improvement of symbiosis theory and ecosystem innovation mechanism. Establish logistic measurement model, set binary dummy variable, take the effect of policy implementation (PIE) as the explanatory variable, add area as the control variable, respectively from the supplier effect, the demander effect, the whole effect into the model, and finally form the model (1), model (2), model (3). Logistic regression analysis was carried out for all effective samples by stata14.  And this paper explains the symbiosis embedding theory reveals the black box of supply and demand symbiosis embedding process of rural tourism ecosystem innovation, answers the complex embedding mechanism that supply and demand symbiosis and rural tourism ecosystem innovation are mutually promoting, and provides a structural theoretical hypothesis for related research topics. This study finds that the accurate supply of government, tourism enterprises, and non-governmental organizations and the accurate selection of rural poor population, service quality, safety and itinerary planning, cultural and lifestyle differences all have significant positive correlation to the innovation of rural tourism ecosystem. The time cost caused by traffic, information loss, degree of fraud and price fraud are negatively correlated to the innovation of rural tourism ecosystem. This is basically consistent with the current reality. Based on the symbiotic perspectives of "supply needs refinement"and "demand needs support", the author proposes: (1) Strengthening the ecological foundation, innovate the ecological mechanism, and improve the symbiotic environment of the ecosystem.Establishing and improving the innovation management system of rural tourism ecosystem, relevant laws and regulations;Establish and improve the coordination and supervision mechanism of diversified subjects, and strengthen the coordination and supervision of diversified interest subjects. Carrying out the dynamic supervision process, establishing and improving the dynamic supervision mechanism. (2) optimizing ecological distribution, strengthen ecological cooperation, and to build a model of ecosystem symbiosis.The innovation of rural tourism ecosystem is implemented from project to community. Project "fine supply", tourism enterprise "fine supply", poor people"fine supply", poor community "fine supply". (3) Strategies such as highlighting ecological characteristics, integrating ecological resources, and improving ecological symbiosis elements are also raised to optimize the innovation mechanism of rural tourism ecosystem. Strengthen the innovation of transportation "supporting demand", infrastructure and supporting service facilities construction; implement flexible working system, implement holiday "supporting demand"; innovate the symbiosis mechanism of diversified capital sources "precise supply supporting demand".     

信息技术走进数学课堂的点滴思考

数学具有形式化抽象特征,对于一些精深的数学概念、繁琐的演算过程、复杂的数形关系书难以想象几何位置关系及一些生产、生活中的实际问题,往往由于教学手段的限制,课堂上难以被讲清,从而造成了教与学的难点．数学观的改变和数学教育的需要促使我们迎接“以计算机技术为代表的信息时代教学”的到来,将信息技术融入课程内容、课程结构、课程教学中,就能够帮助师生突破难点,突出重点,走出传统的呆板、生涩的数学课堂教学模式,建立数学课堂融洽和谐的师生关系,从而达到新课标的要求．     

学科知识网络研究（Ⅰ）引文网络的结构、特征与演化1）

科学引文网络是学科知识网络的重要组成部分,为分析近110多年来图书馆与情报学领域内的引文网络并梳理其知识链,本文利用SSCI数据库全面收集了该领域内85种国际权威期刊的71350篇文献数据,研究了这些论文的被引频次随时间的变化情况,利用Citespace软件绘制百年来的科学引文网络并对中心度较高的关键性节点进行了分析。结果显示图书馆与情报学有影响力的节点文献主要集中出现于20世纪60年代至今,该学科的知识基础在此期间也得以构建起来。另外图书馆与情报学领域引文网络的入度具有无标度特征,文献的出度分布在半对数坐标中具有线性关系,图书馆与情报学领域内文献的被引和参考之比较低,高引论文的出度对入度的影响比较有限。
