| 摘 要： | 根据鲶鱼的听觉特性和夜间活动习性,研制了鲶鱼活动性超声波自动观测系统。观测结果表明,该系统不仅可灵敏地自动记录鲶鱼的活动性,并对其正常活动性无影响,环境声响对该系统无干扰。同时可应用于其他水生动物活动性的自动观测。初步的观测资料表明,1982年1—6月的观测期间,唐山地区发生的两次强余震(M_L5.2和M_L5.5)前48小时内,自动观测到的鲶鱼活动性出现明显增高。

| Abstract: | Based on the characteristics of hearing of catfish and their active habitude at night, we studied and made an automatic observation system with ultrasonic wave for recording activities of catfish prior to earthquakes. Observable results show that this system not only can sensitively record activities of catfish, but also has no effect on their normal activities, and surrounding sounds has no disturbance on it. At the same time, it can be applied to automatic observation of activities of other animals in water.Preliminary observation data show that automatic recording activities of catfish presented an outstanding rinse in 48 hours before two strong aftershocks(ML5.2 and ML5.5) occurring in Tangshan region during our observation from Jan. to June. 1982. |
