查询词典 otoliths

为了阐明乌鱼耳石微细构造、微化学与其初期生活史事件之关系，本研究於西元1996年至2004年在台湾东北至西南沿岸的四个河口域进行乌鱼稚鱼的采样，然后利用光学及电子显微镜、电子微探仪及雷射熔蚀-感应偶合电浆质谱仪分析稚鱼耳石的日周轮、锶钙比及微量元素组成之变化。

The characteristics of three kinds of determination materials of Takifugu obscurusAbe,otoliths,vertebra and opercular had been described and compared the similarities and difference and veracity As a result,the otoliths are the best structure of judging age because the annual ring is very evidence and regularity;the vertebra is the better,it is difficulty of measure;the opercular is only the assistant material.

有关暗纹东方养殖生物学和病害的研究已有很多，但对其年龄鉴定却鲜见报道。在整个形目鱼类中仅见绿鳍马面年龄生长的报道，且作为年龄鉴定依据的材料仅限于脊椎骨[1]。

In this paper, thermoluminescence characteristics of otoliths of the wild carps in the Baiyangdian Lake of Hebei Province and the Miyun reservoir of Beijing were studied, and the difference of energy gap between the fish otoliths in the two regions was analyzed.

本文对生长在河北白洋淀和北京密云水库的野生鲤鱼耳石的热释光曲线特征进行了研究，分析了两水域野生鲤鱼耳石中陷阱深度值的差别。

In the past two or three decades, quite a few achievements have been made in the study of fish otoliths, but no advances in researches on the thermoluminescence characteristics of the fish otoliths have been reported in literature.

鱼耳石的主体由生命矿物文石组成，其研究在过去二三十年中已取得了不少成果，但是将热释光技术用于鱼耳石的研究未见报道。

The content of Fe in lagenal otoliths was not significantly different from that in utricular otoliths and was even lower than that in saccular otoliths. The content of Co in lagenal otoliths was lower than that in saccular otoliths and higher than that in utricular otoliths. The content of Ni in lagenal otoliths was not significantly different from that in saccular otoliths and was higher than that in utricular otoliths.

瓶状囊耳石中Fe的含量与椭圆囊耳石相比无显著性差异且低于球囊耳石；瓶状囊耳石中Co的含量低于球囊耳石，但高于椭圆囊耳石；瓶状囊耳石中Ni的含量与球囊相比无显著性差异，但高于椭圆囊耳石。

The content of Fe in lagenal otoliths was not significantly different from that in utricular otoliths and was even slightly lower than that in saccular otoliths. The content of Co in lagenal otoliths was slightly lower than that in saccular otoliths and slightly higher than that in utricular otoliths. The content of Ni in lagenal otoliths was not significantly different from that in saccular otoliths and was slightly higher than that in utricular otoliths.

瓶状囊耳石中Fe的含量与椭圆囊耳石相比无显著性差异且略低于球囊耳石；瓶状囊耳石中Co的含量略低于球囊耳石，但略高于椭圆囊耳石；瓶状囊耳石中Ni的含量与球囊相比无显著性差异，但略高于椭圆囊耳石。

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。
