【摘要】 鉴于模拟电子技术教材配套练习系统的不足,研究并开发新的模拟电子技术练习系统。新系统内置电路绘图模块,支持用户对题库进行二次开发,采用保存电路图形数据和电路参数的方式存储电路图,降低题库对存储空间的开销,通过在题目中嵌入电路参数随机变化式和标准答案计算代码,实现了电路参数随机变化和标准答案的同步运算,从而达到了开发动态题型的目的。实践应用表明,新系统广受好评,有推广应用前景。更多还原

【Abstract】 By Analyzing the lack of the exercise systems of analog electronic technology,the paper researched and developed a new exercise system of analog electronic technology. The new system contained built-in circuit drawing module,supported the user to carry on secondary developments on the exercise library,and saved circuit diagram by saving the circuit graph data and circuit parameters,significantly reduced the storage space of the exercise library. By embedding circuit,codes of parameter and standard answer can be calculated randomly. It achieved the goal about developing dynamic exercises. Application results showed that the new system was generally praised, and had development and application value.更多还原
