棘鱼

Contemplating the history and development of the museum profession, the comparison that springs irresistibly to mind is with the coelacanth, that remarkble creature whose brain, in the course of its development from embryo to adult, shrinks in relation to its size, so that in the end it occupies only a fraction of the space available to it.

我在考察博物馆专业的历史和发展时，常不自禁的将之拿来和腔棘鱼相比，这是一种特殊的鱼类，它的脑袋在发育过程中逐渐萎缩，以致成鱼的脑袋只占了脑壳的一小部份，与其偌大身躯几乎不成比例。

The coelacanth is a descendant of the ancient marine organism that gave rise to the terrestrial vertebrates more than 360 million years ago.

腔棘鱼的超保守因子是由LF-SINE通过染色体段间互换产生的，该片断可以复制自己并且插入到染色体的不同位置。

Humans are therefore separated from the coelacanth by hundreds of millions of years of evolution, yet the two organisms still share critical DNA sequences.

在海洋生物向陆地脊椎动物的不断进化中该因子一直处于活跃状态，直到物种登入到陆地上。而在腔棘鱼身上该因子仍然处于活跃的状态。

It seems rather doubtful that the modern organization could ever conclusively trace its lineage back to their medieval namesake... but then again, everybody used to think the Coelacanth was extinct.

现在很难说这个组织与中世纪的圣殿骑士又任何传承的关系……不过话又说回来，所有人不都曾以为腔棘鱼灭亡了么，可事实却不是。

The Coelacanth was thought to be extinct; at least until 1938 when Marjorie Courtenay Latimer found just such a fish in a fisherman's boat and took it with her, later sending it to the fish to scientist J.L.B.

过去人们都认为腔棘鱼早就灭绝了。直到1938年，马乔里·科特内·乐泰莫在一个渔民的渔船里发现了一条，随后送到了科学家 J·L·B·史密斯那里。

The coelacanth inhabits the deep sea .

腔棘鱼栖息于深海。

Extinct except for the coelacanth.

除腔棘鱼以外都已灭绝。

While purple-toed, keen-eyed hunters are just a made up example, a real animal that demonstrates this is the three-spined stickleback fish of western Canada.

而紫色脚趾头、敏锐的视力的猎人只是一个虚构的例子，一个真实存在的动物可证明这个事实的就是在加拿大西部生活的有三根脊柱的棘鱼。

While purple-toed, keen-eyed hunters are just a made up example, a real animal that demonstrates this is the three-spined stickleback fish of western Canada. These fish moved into glacier-carved lakes thirteen thousand years ago. Over time, they evolved into two separate species.

紫色脚趾、厉眼的捕食者只是一个例子，而在加拿大西部海域有一种真实的生物名叫三椎棘鱼论证了这一进化历程。3000年前，这种鱼类迁徙到了布满冰川的河流，随着时间过去，他们演变成两种不同的生物种类。

Although the fittest possible stickleback might be both slender and wide-mouthed, these linked traits make such an evolutionary jump unlikely.

虽然可能最适应环境的棘鱼既苗条又有大嘴，这些相连的特征导致了这种不利的突变的进化结果。

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。
