沙蚕

Studying the larvae of the marine ragworm Platynereis dumerilii, the scientists found that a nerve connects the photoreceptor cell of the eyespot and the cells that bring about the swimming motion of the larvae.

研究人员以沙蚕环节动物-岩虫幼体进行研究，发现一个神经连接着眼点光感细胞和控制幼虫游泳的细胞。

The growth of Chinese prawn fed with polychaete worm was significantly larger than that fed with formulated diet. Their carbon conversion efficiency was 26.80% and 13.78% of carbon intake respectively.

中国对虾摄食沙蚕的生长显著大于摄食配合饲料的，摄食沙蚕和配合饲料的碳转换效率分别为摄食碳的 2 6.80 %和 13.78%。

The carbon budget of Chinese Prawn fed with polychaete worm under different salinity and fed with different diets(polychaete worm and formulated diet) under salinity of 31 was studied.

通过室内生长实验的方法测定了中国对虾在不同盐度下摄食日本刺沙蚕及盐度 31海水中摄食日本刺沙蚕和配合饲料的碳收支。

The appearance of heteronereis is related to temperature, especially after a period of relatively low temperature, and the quantity of heteronereis increase evidently with temperature increased to 18～25℃.

异沙蚕体形成与温度有关，特别是在经历了一定的低温期(2～4℃)后，再提高温度至18～25℃，可以有效地促进异沙蚕体形成。

Under artificial cultivation circumstances, the appearance of heteronereis and the swarming behaviour did not show a semiluar phase law. For the mature individuals, if only there is weak illumination, the heteronereis will swarm at every time with the sink being full of water.

在人工养殖情况下，异沙蚕体的形成及群浮并未出现半月相型规律，成熟后只要有微弱的光照，任何时间加水覆盖水槽均可见到异沙蚕体群浮。

The results show that the genetic distance between Lumbrineris tetraura and Chloeia parva is 0.044, Lumbrineris tetraura-Chloeia parva and Capitella capitata is 0.057, Lumbrineris tetraura and Marphysa sanguinea is 0.091, which means Amphinomidae is a ingroup taxon of Eunicida.

结果显示，四索沙蚕－梯斑海毛虫分枝的遗传距离为0.004，－小头虫分枝的遗传距离为0.072，四索沙蚕分枝与岩虫分枝的遗传距离比较大，为0.091。

In the absence of any fossils of the extinct ancestor, zoologists chose to believe that Platynereis 's nervous system was somehow different from the one found in the vertebrate lineage.

在没有找到任何沙蚕绝迹祖先的化石证据的情况下，动物学家们更愿意相信沙蚕的神经系统与脊椎动物的神经系统是不同的。

Omell and Herbert Waite, of the University of California, Santa Barbara, have been studying the jaws of ragworms—which, as careless fishermen who have used them for bait can attest, can give a nasty nip.

然而，最新一个仿生研究对象，看来更让人觉得不可思议。加州大学圣塔芭芭拉分校的克里斯。布鲁美尔跟赫伯特。瓦特，正在研究沙蚕的颌齿。沙蚕咬人蛮疼的，抓过沙蚕做诱饵的漫不经心的渔夫就领教过了。

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。
