耳石的

Similarities in morphology, element ingredient and element content between otoliths in the lagena and those in the utricule suggest that the two types of otolithic organs may play a similar role in sensing gravitational and acceleration signals.

信鸽瓶状囊的耳石与椭圆囊的耳石在形态、元素组成及含量水平上具有相似性，提示这两种耳石器官可能在感受重力和加速度信号中起相似的作用。

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。

Previous research indicated a drastic ontogenetic change in behavior, habitat, body shape, and recombination of tissue during metamorphosing from leptocephalus to juvenile stages. A maximum otolith increment width and sharp decreasing in otolith Sr/Ca ratios resulting from glycosaminoglycan broken–down were observed during metamorphosis.

研究指出，柳叶鱼仔鱼转换到稚鱼的变态过程，须经历行为、栖地转换与身体组织重组等个体发生的剧烈变化；在此过程将观察到耳石日周轮明显变宽、耳石Sr/Ca比因GAGs降解而急速下降等现象。

Based on the domestic and foreign researches on information analysis of statoliths in Cephalopods during recent years, the paper summarized the current status of daily growth increment and microchemistry of statoliths in Cephalopods; and generalized its application in fishery resource and environmental science. In the meanwhile, the paper made the prospects on direction and content of the future research.

文章依据近年来国内外有关头足类耳石信息分析的研究成果，综述了头足类耳石日轮及微量化学的研究现状，概括了耳石信息分析在渔业资源及环境科学等方面的应用，并对今后的研究工作提出了方向与内容上的展望。

There is significant linear relationship between otolith's radius, length, width and the body length.

在耳石径、耳石长度、耳石宽度和体长间存在显著的线性关系。

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。

According to the samples of Ommastrephes bartramii collected by Chinese squid jigging vessels during July to October in 2007 in the northwest Pacific Ocean, the ratio of statolith maximum width to total length, as an indicator of shape change of statolith, was analyzed under different sex maturitiy stages and individual sizes using the method of ANOVA and LSD.

本文根据2007年7～10月我国鱿钓船在西北太平洋海域连续采集的柔鱼样本，以耳石最大宽度MW与其总长TSL之比作为其耳石形态变化的指标，利用方差分析和最小显著差法研究了性成熟和个体大小对耳石形态的影响。

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。

The contents of other metal elements Na, Mg, K, Al, Mn and Pb in lagenal otoliths were not significantly different from those in utricular and saccular otoliths.

瓶状囊耳石中其它金属元素Na、Mg、K、Al、Mn、Pb的含量与球囊和椭圆囊耳石相比无显著性差异，但Zn、Ba、Cu的含量略低于球囊耳石。

The contents of metal elements Zn, Ba and Cu in lagenal otoliths were lower than those in saccular otoliths. Conclusion The contents of magnetic elements in lagenal otoliths of homing pigeons are not much higher than those in utricular and saccular otoliths, which does not support the hypothesis that birds depend on high contents of Fe and Zn in lagenal otoliths for sensation of geomagnetic information.

结果表明成年信鸽瓶状囊耳石中磁性元素的含量极低而且不比内耳球囊和椭圆囊耳石更丰富，从而不支持信鸽因其瓶状囊耳石中含有较高的Fe、Zn等元素而能够感受地球磁场这一假说。

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
