耳石

Although there are a lot of methods to test otolith function,at present ocular counterrolling is the only relative pure indicator of otolith function.It provide a valid method for predicting SMS susceptibility,it has great application prospect in the research of the SMS mechanism and the readaptability of vestibular function after space flight,it also provides great reference in the clinical diagnosis of vestibular problems.

在耳石功能检测的多种方法中，眼球反转检测是较为单纯反映耳石功能的一项生理指标，它提供了一种可以较为有效地预测空间运动病易感性的手段，且在空间运动病机理研究以及航天飞行后前庭功能的重适应研究上有很好的应用前景，同时对临床上前庭功能障碍的诊断可提供重要参考。

To clarify this issue, we carried out a study to determine whether or not otoliths in the lagena of homing pigeons are richer in magnetic elements than those in the saccule and the utricle.

为澄清这个争议，本研究分析成年信鸽瓶状囊耳石磁性元素的含量是否比内耳球囊和椭圆囊耳石更丰富。

Mammals have two otolithic organs, the utricle and the saccule. The macula lagena is another otolithic organ in the inner ear of non-mammals, and the lagena of more advaced birds develops better than that of lower animals.

哺乳动物只含有球囊和椭圆囊两种耳石器官，而非哺乳动物中还存在另外一种耳石器官——瓶状囊。

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。

Methods The otoconia of 18 guinea pigs were damaged by a high G force (10 Gy 5 min), and their utricle macula were observed by scanning electron microscopy at 1 h, 2 d and 8 d after the damage respectively. The elements of different kinds of otoconia were measured qualitatively and quantitatively by electron probe Xray microanalysis.

给予过载刺激(10 Gy 5 min)造成18只豚鼠耳石的损伤破坏，用扫描电镜（scanning electron microscopy，SEM）分别观察过载刺激后1 h、2 d、8 d时其椭圆囊囊斑，用X射线显微能谱分析技术(electron probe Xray microanalysis，EPMA)测量不同形态类别的耳石元素构成。

Japanese eel, Anguilla japonica, is a catadromous fish, that spawned in the sea and migrating between sea- and freshwater. Otolith strontium / calcium ratio has been widely used for recording the migratory history of fish, but the interactive relationship between otolith Sr /Ca ratio and environment factors remained unclear.

鳗鱼为降海洄游型鱼类，一生当中会在淡水与海水之间洄游，近年来有相当多的研究利用其耳石锶钙比来回推鳗鱼洄游环境的历史，因此，本研究期由实验室的控制实验，验证盐度与饵料对鱼体组织锶钙比、耳石锶钙比及分配系数的影响。

From otoliths, the spawning times of these three species are all estimated to occur much later in the year than when small leptocephali are found at sea, indicating that ages appear to be underestimated.

从耳石来看，这三种鳗的产卵时间按照耳石推断出来都比实际发现柳叶鳗的时间要晚一些。

Results In adult homing pigeons, the contents of ferromagnetic elements in lagenal otoliths were less than 0.7% and were the same order in magnitude as those in saccular and utricular otoliths.

结果 成年信鸽瓶状囊耳石中磁性元素Fe、Co、Ni的含量不足Ca元素的0.7％，与球囊和椭圆囊耳石中的含量为同一数量级。

The present study found that the contents of ferromagnetic elements in lagenal otoliths of adult homing pigeons were less than 0.7% and were the same order in magnitude as those in saccular and utricular otoliths.

本研究的结果发现：成年信鸽瓶状囊耳石中铁磁性元素Fe、Co、Ni的含量不足Ca元素的0.7%，与球囊和椭圆囊耳石中的含量为同一数量级。

In the present study, I analyzed the contents of ferromagnetic elemetns and other metal elements in lagenal otoliths of adult homing pigeons with inductively coupled plasma mass spectrometry of high sensitivity(all the contents were normalized to Ca), and compared with those in saccular and utricular otoliths.

为此，本研究中应用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铁磁性元素Fe、Co、Ni以及其它金属元素的含量(以Ca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。

On closer examination, though, this is not a vote for multilateralism but just the opposite.

仔细审视后我们发现，这并非是对多边主义投出的赞成票，而是恰好相反。

Uncovering their weak spots, so I can defeat them.

揭露出他们的弱点，这样我就可以打败他们了。
