简介:摘要本文在深入分析测控主机的结构及原理的基础上,明确测试任务以及测试流程,根据待测信号特征和指标设计测试功能电路,完成了测控主机的PXI-2204数据采集卡的AD测试、DA测试、DI/O测试、计数测试,RS232串口测试、警示灯电压测试、图像采集卡RTV-24测试。按照实际需要,充分考虑实用性、可操作性,完成了适配器的接口、外形设计及内部设置。利用LabWindows/CVI进行程序开发,采用虚拟仪器技术完成了测试功能界面,提供一个良好的人机交互环境。最后通过与测控主机连接测试,验证了自检适配器的有效性。
简介:摘 要: 思维导图是一种有效的创新思维工具,它把知识点与知识点之间相关联,使思维可视化。思维导图主要是从中心概念出发,向四周发散,将知识以脉络的方式呈现出来。政治 学科知识点多、 理论性强 , 通过思维导图学生可以把零散的知识组合起来,形成有条有序的知识网络,有利于培养学生的发散性思维能力。论文 以高中《政治生活》为例,分析 思维导图在高中政治主观题复习中的应用,探索优化高中政治主观题复习策略,提高学生解答主观题的能力,让学生拿高分。 Abstract: Mind mapping is an effective innovative thinking tool, which links knowledge points with knowledge points and visualizes thinking. Mind mapping mainly starts from the central concept and spreads around, presenting knowledge in the way of context. Political science has many knowledge points and strong theory. Through mind mapping, students can combine scattered knowledge to form an orderly knowledge network, which is conducive to cultivating students' divergent thinking ability. This paper takes "Political Life" as an example to analyze the application of mind mapping in the review of high school political subjective questions, explore and optimize the review strategy of high school political subjective questions, improve students' ability to solve subjective questions, and let students get high marks.
