远距离自动控制(遙控)是現代技术的最高成就,它广泛地运用在生产过程中。因此,在中学进行現代生产基础的教学时,就必須向学生介紹遙控的基本原理。在中学的物理学和电工学課本中所研究的現象使我們有充分可能来进行这样的介紹。然而遙控的問題在教学大纲中并未得到应有的反映,在物理学、电工学的课本和教学法参考书中只是略微闡述了一些。在中学里几乎没有能够用来向学生说明遙控装置工作原理所必要的演示和实驗设备。本文主要描述一些远距离自动控制的演示,这些演示是用自制的步进式配电器和諧振继电器的模型来
Remote control (remote control) is the highest achievement of modern technology, it is widely used in the production process. Therefore, in the teaching of modern production base in high school, students must be introduced to the basic principles of remote control. The phenomena studied in secondary school physics and electrotechnics textbooks make it possible for us to make such an introduction. However, the issue of remote control has not been properly reflected in the syllabus, and it is only slightly explained in physics and electrotechnics textbooks and pedagogy reference books. There are few demonstrations and lab equipment in secondary schools that can be used to explain to students the working principle of a remote control. This article describes some of the main remote control demonstration, the demonstration is the use of homemade step-by-step distribution and resonant relay model to
