目的评估自行研制的极低频电磁场和超声波装置驱鼠效果。方法采用自行研制的驱鼠装置,在实验室和现场进行驱鼠效果观察。结果超声波对鼠类摄食活动有明显影响,低频电磁场对鼠血象有明显影响。室外和仓库内驱鼠实验表明,该装置有明显的驱鼠效果。结论装置性能可靠,技术成熟,有良好的驱鼠效果。 Objective To evaluate the effect of self-developed ultra-low frequency electromagnetic field and ultrasonic device driving mice. Methods Using a self-developed rat repeller device, the effect of expelling rat in the laboratory and field was observed. Results Ultrasound had a significant effect on the feeding activity of mice, and the low frequency electromagnetic field had a significant effect on rat blood images. Outdoor and warehouse drive rat experiments show that the device has obvious drive rat effect. Conclusion The device has reliable performance, mature technology and good drive effect.
