双语例句

• Both the amplitude and duration of action potential on the twig end were less than those on the center end. The conduction of nerve impulse was interdicted by 1% procaine.

• Of a nerve fiber or impulse originating outside and passing toward the cerebral cortex.
  指神经元或者神经冲动，源自外界并且向大脑皮层传送。
• The Disappearence of Nerve Impulse Transmission
  神经脉冲传输的消失
• When the nerve endings of the NE concentration is too high, it will feedback and inhibit biosynthesis of NE vesicles. When the impulse reaches the nerve endings, NE released into the synaptic will decrease, which led to the emergence of depression.
  当神经末梢胞浆中游离的NE浓度过高时，会反馈抑制囊泡中NE的生物合成，当冲动到达神经末梢时，NE释放到突触间隙减少，功能降低，从而引起抑郁的产生。
• The materials show: Some special biological mechanisms of nerve send and maintain enough nerve impulse influencing the central nervous system ( CNS), become the tired possible mechanism that produces;
  资料表明：一些特殊的神经生物学机制影响着中枢神经系统（CNS）发送和维持足够的神经冲动，成为疲劳产生的可能机制；
• Conclusion The positive endolymphatic potential is essential for cochlea to transit sound to nerve impulse in physiological condition.
  结论生理状态下的正内淋巴电位是耳蜗将声音能量转变为神经冲动的必要条件。
• Conclusion: Prenatal alcohol exposure had conspicuous effects on auditory nervous system in rats, by step down nerve impulse conduction.
  结论：乙醇胚胎毒性对大鼠听觉神经系统有明显影响，听觉神经冲动传导减慢。
• CONCLUSION An retrobulbar injection of CNTF after optic nerve crush can enhance the responses of optic nerve system, improve the recovery of nerve impulse transition.
  结论视神经损伤后一次性球后注射CNTF在早期加强了神经系统对损伤的反应强度，促进了视神经损伤后神经冲动传导功能的恢复。
• Second, according to the characteristic of the instantaneous change of action potential accompanied by the nerve impulse, we use H-H equation to describe such change, and conduct simulation combined with SR theory.
  然后根据产生神经冲动时动作电位全或无式瞬时快速变化的特点，采用H-H方程作为描述这种变化的神经元模型，结合随机共振理论进行了仿真研究。
