地震检波器用钕铁硼永磁体稳定性研究

Research in stability of a new permanent magnet (Nd-Fe-B) used for geophone

地震检波器作为传感器,被广泛地应用于石油、地质勘探、工程测量等领域。永磁体是检波器的重要部件之一,它不仅影响检波器的性能指标,同时也影响到其价格成本。随着新技术、新工艺、新材料的发展,一种新型的钕铁硼永磁已被广泛地应用于各个领域内。本文从地震检波器性能指标和稳定性的要求着手,论述了应用钕铁硼永磁材料对地震检波器性能及稳定性造成的 影响和解决应用中存在问题的观点与方法。

As one kind of sensors, geophone is widespread used on oil, geology detection and engineering survey. The permanent magnet is one of geophone's important components, which affects its operational specification and cost. With the development of new techniques, new technology and new materials, a new c is widespread used in many fields. In this paper, we discuss how the Nd-Fe-B magnet affects geophone's specifications and stability, and the methods about Nd-Fe-B's application.
