耳石的

By the single zircon U Pb dating method, the quartz syenite porphyny yielded an age of concordance (1 731±29)Ma, and the aegirine augite syenite and syenogebbro are dated upper cocordi...

应用单锆石U Pb法测定年龄，石英正长斑岩谐和年龄为( 1731± 2 9)Ma ，霓辉正长岩、正长辉长岩上交点年龄分别为( 1644± 14)Ma、( 1750± 65)Ma.1650～ 170 0Ma是碱性岩浆活动热构造事件的标志，石英正长斑岩被中元古代晚期的高山河组不整合覆盖，故以 1650～ 170 0Ma作为熊耳群的上限。1650～ 170 0Ma热构造事件是华北地块重大地质事件，有可能是进一步划分中元古代重要的年龄界限。

Use of similar models in ageing other species, along with periodic validation to ensure that the otolith parameter age relationship has not changed over time, could simplify age data collection for population models.

用耳石参数与年龄的关系来鉴定其他鱼类的年龄，要判断这种关系不会随着时间的变化而改变，这样为种群模型收集相应年龄数据就相当容易了。

One-dimensional simple detect system is base on the change of gray level of otolith image along single line, draw an undee profile.

无论哪种建模方法，其识别的基础都是耳石在透射光下所形成的亮度的交替变化。

Albouubes otolith as linearly correlated with body length, and power-functionally correlated with body mass. The early grotI1 of wild T.

自然种群唐鱼的耳石长径与体长呈显著的线性关系，与体质量呈显著的幂函数关系。

Decreasing bone formation may be the main reason for the reducing calcium content in the otoconia. The headward distribution of blood volume may account for the morphological changes in the middle ear and inner ear.

骨形成减少可能是引起耳石中钙含量减少的主要原因；而头部血流量的增多可能是中耳和内耳形态学改变的原因。

European eels are inferred to spawn year-round from otolith analysis, but the smallest, recently hatched leptocephali are found only in late winter and spring.

耳石分析得出欧洲鳗是全年产卵的，但是最小的刚孵化出来的柳叶鳗幼体趋势在冬末春初发现的。

Methods the positioning nystagmic features in 131 patients with bppv treated between april 2004 and march 2006 were recorded and analyzed with video- nystagmography.

对我科2004年4月—2006年3月就诊的bppv 病人131例，应用红外线视频眼动记录分析变位试验诱发的眼震特点，进行分型、定侧，并采用相应的耳石复位技术治疗。

Methods The positioning nystagmic features in 131 patients with BPPV treated between April 2004 and March 2006 were recorded and analyzed with video- nystagmography. After the BPPV types and the affected side were determined, the appropriate repositioning maneuvers were chosen and performed.

The mean back-calculated body-length-at-age, based on otolith, showed that the growth of crucian carp in Honghu Lake was significantly slower than in Dongting Lake.

根据耳石上年轮退算的各龄平均体长结果表明，洪湖鲫种群生长显著慢于洞庭湖鲫种群，其3、5龄的平均退算体长分别相当于洞庭湖1、2龄时的平均退算体长。

Fish have bones in the inner ear, called otoliths , which are much denser than water and the rest of the fish's body.

鱼的内耳中有骨架，被称为耳石，它的比重大于水和鱼身体的其它部位。
