中文摘要：耳石是头足类生态信息的良好载体。

The traditional methods such as morphology and ecology have provided basic tools for identifying the cephalopod structure, in which the way based on statolith aging has become important.

分析认为，头足类种群结构的研究在世界范围内已经取得了很大的进展，传统的形态学和生态学方法为其鉴定提供了基本的手段，其中利用耳石对其生长和产卵季节等进行推算是当前研究的主要手段之一。

With the study and application gradually elevation and improvement for otolith microchemistry of fish, corresponding study in the statolith of cephalopod become popular. Recently, microchemistry study is one of hot topics in fishery animal, and more and more scientists are interested in it as so much biology and ecology information was showed.

中文摘要：耳石是位于平衡囊内起平衡作用的一对钙化组织，它是头足类的加速度感应器，记录其生命周期内的生物和生态信息。

Presently, the main contents for microchemistry study in cephalopod statolith are composed of inorganic and organic molecules, minor and trace elements, isotope as well as microchemical markers. Minor and trace elements were the important part among the application, which played an important role in discriminating different populations, analyzing life history and reconstructing inhabited environment condition.

目前头足类耳石微化学的研究内容主要包括无机和有机大分子、微量元素、同位素、微化学标记等方面，其中微量元素是应用研究的重点，在头足类种群识别、生活史分析及栖息环境重建等方面发挥了重要作用。

The results indicated that the statolith grew constantly in the whole life of O. bartramii.

研究发现，耳石的生长持续出现在柔鱼的整个生命周期。

Statolith One of a number of large starch grains found in the statocytes, plant cells that are thought to be gravity sensitive.

平衡石：是在平衡细胞，即植物中感受重力变化的细胞中发现的多个大型淀粉粒的其中之一。

Using the shape of this embryonic ring was to be applied to measure the variation of the shape of the statolith. This is a useful tool to know the temperature factor during embryonic development by comparing with the shape of the hatchling's statolith.

而出生时期的平衡石形状可以藉由描绘最外层胚胎轮的轮廓来回推，根据出生时期平衡石的相对形状，可以作为推估胚胎所经历过的发育环境条件，可以帮忙了解初期生活史的相关环境条件。

After hatching, squid hatchlings were separated to incubate in two different photoperiod regimes, 12 hr: 12 hr and 24 hr constant light conditions. Squid larvae were maintained as long as possible. Although the trend which older squids have more increments on the statolith than younger squids is consistent, the slope between the increments and survival days is less than one. The time required to form one ring on the statolith is needed for more than one day.

孵出后的个体分别饲养在两种不同的光照周期下，分别为十二小时亮十二小时暗及二十四小时亮两种光周期，在两种光周期下培养的个体都在平衡石上发现新生成的纹路，纹路生成的数量虽然随著培养时间的延长而增加，轮的生成与光照周期间没有相关性，一条新的纹路生成所需要的时间却大於一天，一般需要两至三天才生成一轮。

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。

Changes on the shape of the statolith were observed among different incubated conditions. The shape of the statolith at hatching had obvious differences among different embryonic developmental conditions. The statolith developed in the colder environment had smaller dorsal dome, thinner and shorter rostrum than that developed in the warmer condition.

不同条件下培养的幼体在其平衡石的型态上有所差异，其型态上的变化随著培养的条件而有显著的改变，在较冷的条件下培养的个体拥有较短小的钝端比例之平衡石，而在较高温条件下培养的个体则是拥有较长比例钝端的平衡石。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
