The electric elevator is an essential means of transport of tower , is used for perpendicularity conveying the passenger and the goods, go along controls tradition lift control system adopt relay-- contactor mainly , whose shortcoming is that contact is many , the malfunction leads high reliability, difference , the amount of work being maintained to wait greatly, but adopt the navar that PLC is composed of to be able to resolve the above-mentioned problem very good.

电梯是高层建筑不可缺少的运输工具，用于垂直运送乘客和货物，传统的电梯控制系统主要采用继电器--接触器进行控制，其缺点是触点多，故障率高、可靠性差、维修工作量大等，而采用 PLC组成的控制系统可以很好地解决上述问题。

Neurotrophic factors is a kind of chemistry which can increase the survival rate of neurone and the growth of nerval spines, it is important in neurone development, neurite growth, transmitter synthesis and cell languish.

神经营养因子又具有促进听觉神经系统发育并维持其正常功能的作用，其作用贯穿于从听板形成直至Corti器毛细胞与传入、传出神经末梢纤维之间建立突触关系的全过程。

ResultsThere was no expression of Caspase-3 in group A. The expression of Caspase-3 in group C was decreased compared with that in group B（P＜0.01. In groups B and C, expansion and vacuolization of mitochondria, swollen neurons and apoptotic bodies appeared, which suggested that WBH could induce neuron injury, and the neuron injury in group C was more severe than that in group B.

结果A组大鼠海马区神经元无Caspase-3表达，B、C两组大鼠海马区神经元有Caspase-3表达，B组较C组Caspase-3表达平均灰度值减小。B、C两组大鼠海马神经元超微结构发生改变、细胞器水肿，部分线粒体空化，内质网稀疏，突触前膜、后膜结构不完整，可见自噬体结构；B组大鼠的神经元超微结构损害较C组轻。
