查询词典 homing

Methods The contents of ferromagnetic elements and other metal elements in lagenal otoliths of adult homing pigeons were precisely analyzed with inductively coupled plasma mass spectrometry of high sensitivity, and then they were compared with those in saccular and utricular otoliths (all the contents were normalized to Ca).

应用具有高灵敏度和稳定性的电感耦合等离子体质谱法测定成年信鸽瓶状囊耳石样品中磁性元素Fe、Co、Ni以及其它金属元素的含量(以Ca含量作为基准的百分比含量)并同内耳的球囊和椭圆囊耳石中的这些元素的含量进行比较。

The contents of metal elements Zn, Ba and Cu in lagenal otoliths were lower than those in saccular otoliths. Conclusion The contents of magnetic elements in lagenal otoliths of homing pigeons are not much higher than those in utricular and saccular otoliths, which does not support the hypothesis that birds depend on high contents of Fe and Zn in lagenal otoliths for sensation of geomagnetic information.

结果表明成年信鸽瓶状囊耳石中磁性元素的含量极低而且不比内耳球囊和椭圆囊耳石更丰富，从而不支持信鸽因其瓶状囊耳石中含有较高的Fe、Zn等元素而能够感受地球磁场这一假说。
