摘要
在一般文献对低噪声电流灵敏放大器分析的基础上，针对电磁干扰对放大器的影响进行理论分析，并提出近场感应、静电耦合感应对核子秤前置放大器的影响及需要采取的措施。
On the basis of the general analyses of sensitive low noise amplifiers, the effects of electromagnetic interference on the preamplifier of a nuclear scale are theoretically analyzed. The effects of near field induction and electromagnetic coupling induction are also studied;besides, some corresponding measures are recommended.
