前肝间质

Using the immunohistochemical technique, nerve cell bodies and fibres immunoreactive to the anti-Met-enkephalin sera were observed in the cerebral ganglia, pedal ganglia, visceral ganglia, inspect ganglia and coat ganglia of Octopus ocellatus. Met-ENK immunoreactivity was also localized in the mouth, esophagus, craw, stomach, stomachic caecus, the epithelium of the intestines, rectum, sialoid gland, liver, branchia, branchia gland, ventricle, branchial heart, kidneys, ovary, fallopian tube, back of mantle, abdomen of mantle, wrist, membrane of wrist, funnel, and immunocytes of Octopus ocellatus.

免疫组织化学定位结果表明：(1)在短蛸的脑神经节、足神经节、脏神经节、视神经节、外套神经节、口球、食道、嗉囊、胃、胃盲囊、肠、直肠、前唾液腺、后唾液腺、肝胰脏、鳃、鳃腺、心室、鳃心、肾静脉腺质附属物、卵巢、输卵管腺、外套膜背面、外套膜腹面、腕、腕间膜、漏斗中检测到呈不同阳性反应的Met-ENK分子。

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。
