摘要
本文研究了虎皮鹦鹉对正弦振动的敏感性，旨在探索其腿部存在赫氏小体，和阐明其震前声行为反应与地面振动的关系提供依据。虎皮鹦鹉对５０－８０Ｈｚ的正弦振动不敏感，振动位移约２００－５０μｍ才可能激起声行为反应．但对１００－２５０Ｈｚ的正弦振动具有显著的敏感性，反应阈值约１０－２μｍ。对１３０－１７０Ｈｚ和２００－２５０Ｈｚ阈值反应，约７０％的潜伏期（ＬＰ）分别为ＬＰ＜３０５和ＬＰ＜１５ｓ。
On the basis of a study on acoustic behavior in the Budgerigar,the vibration sensitivity of Budgerigar is further studied by the using oacoustic behavior method. The investigation aimed at exploring the Herbst corpuscle of Budgerigar legs,and some bases were provided for expounding the relationship between acoustic behavior responses of the Budgerigar and ground vibrations excited geosounds before earthquakes. In the budgerigar, significant sensitivities to sine vibrations at 5 - 80 Hz within the frequency band of microseisms were not found,and vibration displacements of about 200- 50μm might just excite acoustic behavior responses. But the Budgerigars have significant sensitivities, to sine vibrations at 100 - 250 Hz within the dominant frequency-band of premonitory sound-vibrations of earthquakes. The response thresholds to vibrations at 100、 130、 170 and 200 - 250 Hz are about 10. 0. 4. 3. 2. 5 and 2. 0 μm, respectively, and latent periods(LP) of responses of 70% or so to vibrations at 130. 170 and 200 - 250 Hz are separately ordered LP < 30s. LP < 30 s and LP < 15s, i. e. it is similar to vibration sensitivities of the Herbst corpuscle at pigeon legs.
