摘　　要：模拟高速公路路面状况,对高、中性能4种烧结钕铁硼进行了冷、热震实验和振动实验,认为烧结钕铁硼永磁体可以作为智能高速公路导航用信号源的选材参考,且烧结钕铁硼的微观结构对信号源的稳定性有重要影响。The cold - and hot - vibration tests and vibration tests are conducted with 4 high and medium performance kinds of sintered Nd - Fe - B under simulation for superhighway surface condition. It is considered that sintered permanent Nd - Fe - B magnet can be used as material for navigate signal resource of superhigh- way and its micro - structure has an important role to stability of the resource.
