The latedischarges decreased from 9.29 ± 0.97 to 6.71 ± 0.68 with the A-fiberconditioning stimulus increasing from 1 to 5 (n〓8, P〓0. 05).(7) The intervalbetween the conditioning stimulus and test stimulus (C-T interval) wasincreasing, the inhibition tended to plateau off. At shorter time intervalsthe inhibition became more effective. When C-T interval was limited in 50ms,the inhibitory effects was the strongest, here, the late discharges reducedfrom 12.57±1.21to 2.29±0.42 (n=11, P＜0. 01).(8) Behavior research showedthat the rat model of snake venom exhibited neuropathic pain with heathyperalgesia, cold and mechanical allodynia, which corresponding to the acuteelectrophysiological findings.

At the same time, most WDR neurons failedto respond to the light brush applied to the receptive fields, but they couldbe intensively excited by the noxious pinch.(5) The latency of the latedischarges was shortened from 118.83 ± 3.67ms to 50.72 ± 1.36ms (n〓32, P〓0. 01).(6) Preceding graded number of A〓fiber conditioning inputs (〓mA, 100 μs) delayed the C-activity evoked by the following nociceptive teststimulus activating both A- and C-fiber applied to the sciatic nerve.

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。
