| Abstract: | Many of the experimental circuit-plates are used in electronic experiment teaching, Because of the carelessness or absence of a safeguard,the damage often takes place. In this paper,the reason is analyzed and measures to preventing thedamage are studied theoretically,a few kinds of guard circuit are designed for carry-in terminal, carry-out terminal and source terminal. The safeguard is provedsuccessful in practice. |
