电子负载由于其诸多优点，现已替代传统负载广泛应用于电源类产品测试环节。从程控直流电子负载的整体设计方案入手，采用STM32F103VCT6作为中央控制器，运用多通道AD技术对多路并联的MOSFET上的电压及各支路电流进行实时监测，控制工作在线性状态的MOSFET上的电流，以实现电子负载的恒流、恒压、恒功率和恒电阻4个功能。详细研究了MOSFET寄生电容引起的自激振荡及消除方法以及PI调节器、滤波器的设计，提出了一种提高多路MOSFET并联的电子负载的稳定性的方法。针对所提出的电子负载设计方案制作了实验样机，并对其进行了测试、分析和再优化。

Electronic load due to its many advantages, it has been replacing traditional load test is widely used in power supply products. From the overall design scheme of program-controlled dc electronic load, using STM32F103VCT6 as central controller, using multi-channel AD technology of multichannel parallel voltage of MOSFET and each branch circuit for real-time monitoring, control on the linear state of the MOSFET current work, in order to realize the electronic load constant current, constant voltage, constant power and constant resistance four functions. Detailed study of the self-excited oscillation caused by MOSFET parasitic capacitance and eliminating method and the design of PI regulator, filter, this paper proposes a improved multiplex MOSFET parallel method of the stability of the electronic load. In view of the proposed design of the electronic load produced a prototype, and carries on the test, analysis and optimize.

作者主要针对中学物理实验教学的改革和创新提出自己的几点看法和建议。首先，作者指出随着2001年义务教育新课程标准的改革，中学物理实验教学的重要作用得到重视，并分析了具体的改革方向。其具体的改革措施：1、改革了实验的数量；2、改革了实验教学方法。其次，作者作为教者，对具体的中学实验教学中，如何把握改革方向，进行创新的物理教学实践提出了几点建议：更新实验教学思维；实验教学方法进行创新；实验教学评价进行创新。最后，本文作者强调了一般物理实验教学中，所忽略的实验后的反思，强调了反思对于开发学生创造性思维的作用，并指出了反思的具体内容：反思实验原理、实验方法、实验现象、实验规律、实验异同点、实验注意事项等。

The author puts forward some opinions and suggestions on the reform and innovation of the middle school physics experiment teaching. First of all, the author points out that with the reform of the new curriculum standard of compulsory education in 2001, the important role of the middle school physics experiment teaching has been paid attention to, and analyzes the concrete reform direction.

Its specific reform measures: 1, the reform of the number of experiments; 2, the reform of the experimental teaching methods. Secondly, the author as a teacher, to specific experimental teaching in secondary schools, how to grasp the direction of reform, innovation of physics teaching practice puts forward several suggestions: update the idea of experimental teaching; experimental teaching method innovation; evaluation of experiment teaching innovation.

Finally, the author emphasizes the general physics experiment teaching, ignore the experimental reflection, emphasizes the reflection effect on the development of students' creative thinking, and pointed out that the reflection of the specific content: Reflections on the experimental principle, experimental methods, experimental phenomenon, experimental rules, similarities and differences between the experimental, experimental note.

所谓的课堂导入就是在讲授新课之前，教师根据一定的教学目标、教材特点、有意识有目的地运用各种教学媒体，通过不同的方式导入新课的一种教学行为，是课堂的起始环节，是课堂教学成败的关键因素之一。精彩的课堂导入无疑是为整个化学课堂奠定良好的基础。教学实践证明，精心设计的导入方式，能激发学生学习的积极性和自觉性，引起学生对所学课题的注意，为学习新课题做好心理准备。在新课题学习时，教师要运用各种导入方式将学生吸引到教学活动中来，激发学生的学习兴趣，开启学生思维之窗，使学生心倾神往。本文总结了教师在化学教学中课题导入存在的一些问题，以及相应的策略，并在结合教学实际情况下，列举了十种常见新课导入的方法，以便参考交流。

Summary called before the import is to teach the new curriculum in the classroom, teachers based on certain characteristics of teaching objectives, teaching materials, conscious purposeful use of various instructional media through different ways of importing new lesson one of teaching behavior, is the starting class link, is one of the key factors of success or failure of classroom teaching. Wonderful classes import is undoubtedly lay a good foundation for the entire chemistry class. Teaching practice has shown that well-designed import mode, can stimulate the enthusiasm of the students ' learning and awareness, attract the attention of students on the subject, prepared for learning new topics. When a new thematic study, teachers use a variety of import students attracted to teaching activities, arousing students ' interest in, turn on the window on the students ' thinking, students pour longing hearts. This article summarizes the teachers in the teaching of chemistry subject imported some of the issues and appropriate policy, and under the combination of the actual situation, lists of ten common new class import method, in order to refer to the Exchange. …… 此处隐藏：2432字，全部文档内容请下载后查看。喜欢就下载吧 ……
