According to the changes of otolith daily growth increments, the leptocephalus completed metamorphosis is approximately 14d during rearing conditions.

根据耳石日周轮的变化与发育阶段的关系，得知变态期大约14天，以此将耳石划分为柳叶鱼期、变态期和稚鱼期三个发育阶段。

The leptocephalus were immersed in a tetracycline solution with a concentration of 350μg ml-1 to produce a fluorescent TC mark in the otoliths as the onset of the experiment. They were then reared under a constant condition of 25oC, 15psu and light cycle of 10D/14L for 16 days to investigate the ontogenetic somatic and otolith changes during metamorphosis.

标本携回实验室后，先以浓度350μg ml-1的四环素（Tetracycline， TC）萤光溶液标示，以便在耳石上留下萤光环记号当作实验的第1天，而后饲养在温度25℃，盐度15psu，光周期10D/14L下，直接观察变态过程的连续变化。

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。

Results 1 Hypergravity influenced early development of zebrafish from zygote to early larva, and otolith size significantly larger in the early stage (P.01) but decreased subsequently. 2 Examined with EDAX, the contents of sulfur and Sr increased while Ca and Na contents decreased. 3 It was observed that sagitta and lapilli otoliths were fused into one otolith.

结果 1斑马鱼从鱼卵向早期仔鱼发育过程中超重环境影响仔鱼发育，耳石形态在初期显著变大(P.01)，其后耳石变小；2EDAX检测表明，耳石中S和Sr含量升高，Na和Ca的含量减少；3出现矢耳石与微耳石融合的现象。

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。

According to the fact that the otolith system is overcritically damped and the max- imum displacement of the otolith,δ〓 is independent of the dynamics, the upper limit of the Young's module of the gel layer and the estimated value of the dimensionless parameter εwere given,〓 which provided the theoretical basis for the experimental method and the theoret- ical analysis.

根据耳石层运动高度过阻尼而且最大位移〓与运动模式无关的事实，理论上给出了胶质层的Young's模量的上界估计表达式以及无量纲参数ε的参数估计式为〓从而为实验测量方法和理论分析提供了理论依据。

Otolith is calcareous concretions in fish inner earsIts composition and structure are very stableIts accretional growth follows a circadian rhythm that is physiologically controlled and influenced by environmental conditionsOtolith acts as biological archives providing the basis for the reconstruction of individual life traits and environmental parametersThe paper focuses on fish otolith trace elements and their isotopes, general testing methods and the prospect and problems of its application in environmental detection in recent 20 years, hoping that it could provide researchers with some thoughts and could expand its potential application in environmental science.

鱼耳石是鱼类内耳中的钙质沉积体，组成和结构非常稳定，它的生长轮受其生理控制和环境条件影响有规律地昼夜生长。耳石可作为鱼类的生物学记录者并为重建其生活特征和环境参数提供依据。文中就近20年来国内外关于鱼耳石微量元素和同位素方面的研究热点、鱼耳石元素研究中常用的测试分析方法以及其在环境监测中的应用前景和存在的问题作一整理和综述，望能为广大耳石研究者提供一些思路和揭示其在环境科学中的广阔应用前景。
