Humans orientate in 3D by using otoliths, small crystals of calcium carbonate and protein that shift on hairs in the inner ear. Forces acting on these grains as a person moves mean they can sense acceleration and gravitational pull.

人类通过利用耳石、小晶体碳酸盐和内耳毛发中的蛋白质来产生三维立体感，当一个人运动时，力量就会施加在这些微粒上，从而让人感受到加速度和重力牵引。

Otolith microstructure and microchemistry studies have revealed various aspects of their early life history that relate to their oceanic larval migration.

耳石微结构和微化学研究已经揭示了影响它们洄游过程中早期生活史的各种影响因素。

Studies of otolith are the basic of research on growth and early life history of fishes.

摘 要：鱼类耳石研究是鱼类生长和早期生活史研究的基础。

Analysis of otolith morphology is an effective tool for fish stock identification.

结果表明耳石形态学分析是鱼类群体鉴别的有效手段。

Computer identification on otolith microstructure of fish.

鱼类耳石微结构的计算机自动识别。

The principal components of the vestibular system are the semicircular canals and the utricle and saccule.

半规管是主要的旋转运动感受器，椭圆囊和球囊内有听斑，其中含有耳石。

Ninteen cases of posterior semicircular canal BPPV were treated with otolith reposition.Reexamined after 2 weeks,14 cases disappeared vertigo,2 cases had no positional vertigo but they were dizzy,2 cases improved the syndromes,1 case had no effeciency.

内容提要用Epley首创的耳石复位法治疗后半规管性良性阵发性体位性眩晕。2周后复查，结果显示，眩晕消失14例，无体位性眩晕，但有头昏2例，眩晕症状改善2例，无效1例。

It remains disputable that birds can obtain geomagnetic information for homing because otoliths in the lagena are rich in elements Fe and Zn.

有人认为瓶状囊的耳石中Fe、Zn等元素含量较高，使得鸟类能够感受地球磁场而具有导航能力，但这个假说目前还存在争议。

The macula lagena is innervated and has neural projections to the brainstem, but its physiological function is still unclear. It remains disputable that it is because otoliths in the lagena are rich in elements Fe and Zn that birds can obtain geomagnetic information for homing.

有人认为瓶状囊的耳石中Fe、Zn等元素含量较高，使得鸟类能够感受地球磁场而具有导航能力，但对于这个假说目前还存在争议。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。

The factory affiliated to the Group primarily manufactures multiple-purpose pincers, baking kits, knives, scissors, kitchenware, gardening tools and beauty care kits as well as other hardware tools, the annual production value of which reaches US$ 30 million dollars.

集团所属工厂主要生产多用钳、烤具、刀具、剪刀、厨具、花园工具、美容套等五金产品，年生产总值3000万美元，产品价廉物美、选料上乘、质量保证，深受国内外客户的青睐
