Several design examples from the author ' s experiences are used to explain how to induce students to analyze the key points in the research topic , how to make an analysis and computation according to those key points and how to test or simulate the results 文章结合作者教学实践并通过实例,介绍了如何引导学生分析课题中的知识点,围绕知识点进行分析计算,并且测试和仿真实验结果以达到课程教学目的。
The mathematical model of the apf with proposed control method was found , and the according circuit was constituted . design example is given using a two - level ac - dc boost topology . a prototype of 500w was developed to demonstrate the performance of the apf with new control method 由于运用了单周控制理论,输入电流的补偿是在每一个开关周期之内完成,不存在a / d 、 d / a转换和运算延时; ( 3 )响应快,因而具有很好的动态补偿性能。
The possible shear of the upper chord will change beam from flexural member to member under flexure and compression force . this is emphasised through design example . as a result , we find that composite floor system is good for reducing the height of floor system 在组合楼盖体系设计中,笔者指出,可能的桁架弦杆剪力会使作为桁架弦杆侧向支承的梁由弯曲构件变为压弯构件,这是在与桁架体系相适应的楼盖体系设计中应该注意的一个环节。
With a mixed digital and analog design example , comparing with the traditional virtual instrument , it indicated that the function of modem virtual emulative instrument is stronger , the usage is close to the practice more , which represents the development direction of virtual instrument 通过与实际仪器的比较,以及具体数模混合电路的仿真分析,说明了现代虚拟仿真仪器比传统虚拟仪器功能上更强大,使用上更贴近实际,是今后虚拟仪器的发展方向。
