呼吸神经

Weeks: fetal grow to 0.85 centimeters, fetal head, brain vesicle, the amount of facial organs, respiratory, digestive, nervous and other organ differentiation, B-sac is clearly visible, and see fetal bud and fetal heartbeat.

6周：胎儿长到0.85厘米，胎儿头部、脑泡、额面器官、呼吸、消化、神经等器官分化，B超胎囊清晰可见，并见胎芽及胎心跳。

It has been speculated that,as the blowholes evolved and migrated to the top of the head,the neural pathways serving sense of smell may have been nearly all sacrificed.

据推测，随着鲸的呼吸孔的演化，并移到头顶，嗅觉神经可能全部消失了。

可以推测出，当呼吸孔进化发展到头顶时，为嗅觉服务的神经感官系统几乎都牺牲了。

据推测，由于呼吸孔转移到头顶，鲸类的嗅觉神经通路几乎退化。

In this "five-step", the evolution of the first step in the series of groups of animals very strange: 14 more haikou insect specimens comparative anatomy studies show that, they not only, and the lack of chordomas in skin, muscle, breathing, circulation, neural organs such as the system with the fundamental difference between the existing chordates, One of the most distinctive is the gills of six foreign composed of respiratory system, and this is the mouth of higher animals in the gills.

在这分&五步走&的演化系列中，&第一步&的动物类群十分奇特：对1400多枚海口虫标本进行比较解剖学研究表明，它们不仅缺少脊索构造，而且在皮肤、肌肉、呼吸、循环、神经等器官系统上与脊索动物存在着根本差别；其中最为独特的是其由6对外鳃组成的呼吸系统，这与较为高等的后口动物的勤鳃迥然有别。

Methods Serotypes and drug resistance of Pseudomonas aeruginosa isolated from environment and patients' sputum in ICU of respiratory, neurological, anesthetic departments were detected by Pseudomonas aeruginosa serotyping kit.

采用日本生研株式会社的铜绿假单胞菌血清分型试剂盒，对某院呼吸内科、神经内科、麻醉科ICU住院患者痰液及相关环境标本中分离的铜绿假单胞菌进行血清学分型及耐药性监测。

They can also cause a neurological disorder known as tick paralysis.

有些硬蜱在叮刺吸血过程中唾液分泌的神经毒素可导致宿主运动性纤维的传导障碍，引起上行性肌肉麻痹现象，继而可导致呼吸衰竭而死亡，称为蜱瘫痪。

At the same time, in order to make more efficient use of mass and acceleration, it is important to note that state of mind and nerves, the three conditions, such as respiratory regulation.

同时，为了更有效率地使用质量和加速度，还必须注意到精神状态及神经、呼吸调节等三个条件。

Presently, the study of hypoxia and its adaptation mechanism is mainly focus on the oxygen intake related system, include respiratory, circulatory and central nerve system which was highly sensitive to the concentrition of oxygen.

目前，研究者采用分子生物学、分子遗传学、细胞生物学、免疫学及电生理学等多种技术和手段，在整体、器官、组织、细胞和分子水平上，对神经、血液-造血、循环、呼吸及内分泌等系统在低氧条件下其功能的改变及低氧适应机制进行了较全面和系统的研究。

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。
