绪论翻开教科书的末页,往往能看到书中某些章节的习题答案。这些答案,一般地说都是不会有什么错误的,因为编者对每一道习题都经过仔细的校验,花费了很多的时间和精力。学校里每次期末考试,任课老师出完考题以后,还要对每一道试题作出标准答案,也很费时间。笔者从事电路基础理论教学多年,每当出题阅卷时总会闪念出一种幻想;如果有一种最简捷的办法就好了。经过长期探讨,终于研究出《图象电路》这一新的电路分析方法,基本上较为理想地解决了以上问题。现连载发表,借此和有关同志共同商榷。 Introduction Open the textbook of the last page, you can often see some of the chapters of the exercises answer. These answers, in general, are not wrong, because the editors have carefully checked every exercise and spent a lot of time and effort. Every final exam in the school, after the teacher finished his exam, but also for each question to make a standard answer, but also time-consuming. The author engaged in teaching circuit theory for many years, whenever the title marking volume will always flash an illusion; if there is a simplest solution just fine. After a long period of discussion, finally, a new circuit analysis method of “image circuit” was finally developed, which basically solved the above problems. Now published in series, to discuss with the relevant comrades.
