汇川H2U系列PLC之间RS-485通信的实现

主要研究了汇川公司H2U可编程控制器(PLC)的通信技术,实现了两个H2U系列PLC之间基于RS-485的通信,并详细介绍了PLC之间通信的硬件连接方式、通信串口参数配置、触摸屏画面的设计以及程序实现。所讨论的方法已在采用H2U PLC及辅助设备组建的"运动控制系统"课程的教学实验平台上进行了验证,可以拓展应用于多台H2U PLC之间以及其他设备与H2U PLC之间的RS-485通信实现,对工程应用具有一定的借鉴意义。     

Exploring Developmental Appropriateness of Multitouch Tables in Prekindergarten: A Video Analysis

This study explored how developmentally appropriate practices influenced the affordances of a multitouch surface in an early childhood classroom. Children, ages 4 to 5 years old, were videotaped while engaged in a storymaking application on a multitouch table. As a result of the study, we found that some challenges with the functionality undermined children's autonomous control. The researchers observed numerous instances of issues with control of the medium, including height of the table, sensitivity to multiple types of touch, and limited instructions and prompts. Implications for future research and practice are discussed.     

反垄断法律中的一个经济学谬误——关于禁止低于成本竞争的解析

很多国家都将低于成本竞争行为归结于垄断,并通过法律加以禁止,然而如果我们运用经济理论从立法依据的科学性和法律实施的操作性分析,可以清楚地看出这一法律规定的无效性,这一分析过程和结果可以给我们的反垄断立法提供一些有价值的参考。

以德行政与反腐倡廉--兼谈中国传统行政道德的传承和发展

行政道德对促进反腐倡廉建设具有导向、控制、调节、教育和激励等功能。现阶段，由于我国社会主义市场经济发育不成熟，他律的缺失以及道德建设的滞后，进一步导致了腐败问题的产生。为了适应新形势发展需要，我们必须在继承和弘扬传统行政道德精华的基础上，赋予新的内容，明确政府工作人员的道德规范，加速行政道德法律化，促进我国的反腐倡廉建设。     

触屏式数控机床维修教学设备设计

在数控机床装调与维修实训教学过程中,如何直观高效地进行电气控制线路故障逻辑分析及查找,数控系统参数误设的恢复,故障现象和故障类型的必然性联系判断,采用PMC编程法的机床功能修改以及机电联机调试等实训课题是目前数控设备应用与维护等相关专业学习中普遍存在的难点。针对这些关键问题,基于触摸屏和强抗干扰技术设计出自动设故的数控机床维修教学设备,该设备具有设故高效率、智能化、成本低等特点。该项目的完成为机床装调与维修、电气控制等实训教学创造了有利条件,同时提升了教师的教学水平和学生的综合能力,为进一步扩大校企合作领域奠定坚实基础。

Questioning the no-touch discourse in physical education from a children's rights perspective

In this paper we question the rationality of ‘no-touch policies’ and offer an alternative approach to the matter of physical contact between teachers and students in the context of physical education (PE) in schools. Earlier research has drawn attention to how a discourse of child protection is starting to affect how physical contact is viewed in PE practice. The avoidance of intergenerational touch is increasingly justified by referring to the children's rights agenda. Here, arguments for ‘no-touching’ are linked to children's right to be protected from harm. In the paper we explore a children's rights-based viewpoint that supports the use of and need for physical contact in PE teaching by developing theoretical and practice-based arguments. An alternative children's rights perspective, based on rights theorising, is used to formulate the theoretical argument. Interviews with 16 PE teachers about their experiences of physical contact in their pedagogical work form the practice-based arguments. The two arguments provide a way of looking at intergenerational touch in education from the vantage point of children's human right to develop to their full potential, which can support a need for physical touch in pedagogical situations.
