鳍

This study is mainly concerned about the cooling performance of the heat passage from the aluminum substract to the fins.

本研究主要探讨从铝基板到鳍片的散热性能。

Although reducing the number of fins increases thermal resistance and the substract temperature, the measured data indicates that the thermal resistance of the road lamp is low enough to ensure sufficient cooling capability and safety chip temperature at the rated operating power.

减少散热鳍片的数量虽然会增加热阻与铝基板的温度，但是实验数据显示本灯具的散热路径热阻甚低，足以提供本灯具在额定功率的散热性能，确保晶片维持在安全的工作温度。

The cercariae′s tegumental has secreted and excreted function. The tail bin of it was described,which can help it working in the water.

尾蚴的体被具有分泌、排泄功能；尾蚴尾部有鳍，有助于尾蚴在水中活动。

Compared genes up- and down-stream IL- between Tetraodon nigroviridi, Fugu rubripes and human, a high degree of conservation of synteny was found.

基因定位比较显示，IL-基因在黑青斑河豚、红鳍东方豚以及人类中具有保守的共线性。

Preliminary experiences in the development of bluefin tuna Thunnus Thynnus (L., 1758) electroslaughtering techniques in rearing cages

随着蓝鳍金枪鱼经济重要性的日增以及市场供应的需求，金枪鱼养殖场数量不断增加。

All specimens of Thunnus albacares were collected from off the coast of Tongtung. Kidney tissues were spliced and cultured in vitro.

本研究自东港外海采得数尾黄鳍鲔样品，取鱼体之肾脏组织进行培养后，制作染色体玻片标本。

The blue elephants landed in the sea and their wings became fins. They are whales, the trunkless elephants of the oceans.

蓝色的象降落在大海里，他们的翅膀变成了鳍，成了鲸鱼，海里没有鼻子的象。

Refer to the finned tube separator and the uniflow cyclone separator, the effects of the inlet particle concentration on the separating efficiency and the pressure lose is studied.

针对鳍片管束分离器和下排气旋风分离器，研究了入口颗粒浓度对分离效率及阻力的影响

This new type seperator gives a beutiful future for the solving of the problem. Besides of this, the seperation function and structive ameliorations of uniflow square seperator and finned tubes seperator were studied systemly, and with the contrast with other type of separtors, have higher seperation efficiency. The uniflow square seperator can reach a much ligh seperation efficiency when it was ameliorated.

并对新型下排气方形分离器和鳍片管束惯性分离器的分离性能和结构优化进行了系统的研究，在对其它几种分离器研究的同时进行了对比，指出方形下排气分离器在结构优化后可达相当高的分离效率，与常规圆形分离器相当，能承担高倍率循环床的物料循环，结构布置得到极大的简化。

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。
