耳上记号

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。

The marks we found in the otolith provide the feasibility in studying the early life history events of the mullet.

利用这些耳石上的特殊记号，可以回推乌鱼初期生活史的成长史及洄游过程。

It goes back to what I told you...

With a supporter in Mr Charest and an admirer in Mr Dumont, Mr Harper may be encouraged to call an election himself.

由于在沙雷那边有个支持者，杜蒙那边有个崇拜者，鼓励哈珀为自己举行一次选举。
