磁探技术中一种新型磁激励系统

New Magnetic Impelling System in Magnetic Survey Technology

介绍了所研制的用于磁探技术中的一种新型磁激励系统．通过对磁激励系统的理论分析，阐明了各单元电路的功能及相互关系，给出了各结点的波形，着重分析了非线性振荡系统的机理．这种磁激励系统可使功率损耗降至原来的１／４，甚至更低，温漂也只有原来的１／１０，时漂也仅为原来的１／１０．

This paper introduces a new magnetic impelling system magnetic survey technology.By analysing magnetic impelling system,the function and relation of every circuit unit are described, the figures of voltage wares are given,and the mechanism of nonlinear vibrational system is particularly analysed. New magnetic impelling system can reduce power loss to one fourth of the origin,temperature drift to one tenth,and time drift to one tenth.
