     目的 提高非稳态噪声性耳聋发病率预测精度。
短句来源
     Methods According to the mapping relation between the incidence rate of the noise deafness and their factors, the model of BP neural network was established to forecast the incidence rate of deafness induced by instable state noise.
     方法 根据噪声性耳聋的发病率与其影响因素之间存在的映射关系 ,建立反向传播神经网络 (BP神经网络 )模型 ,用于非稳态噪声性耳聋发病率的预测。
短句来源
     Results The model of BP neural network for forecasting the incidence rate of deafness induced by instable state noise would be composed of two input units and one output unit and 9 implicit units. The relative error and the average error of the forecasting values appeared to be less than that of the traditional forecasting model. The effect is greatly satisfying.

短句来源
  non steady state noise
     The present experimental study was to investigate the damaging effect of non steady state noise on animal behavior and free cardiac radical. Subjects(rats)in three experimental groups were exposed to non steady noise produced by multi functional wood craft machines and electric impact drills for 5,10 and 20 days respectively.
     本研究用采集的多用木工机床和冲击电钻发出的噪声对 5天、1 0天和 2 0天三个噪声干扰组的动物进行干扰 ,以研究非稳态噪声对动物行为及心脏组织自由基损伤的影响。
短句来源
     The following conclusions were:first,non steady state noise had great influence on animal behavior,and the longer the exposure was,the greater the influence became.
     因此得出结论 :①非稳态噪声可以对动物行为产生影响 ,并随着噪声暴露时间的延长而增强 ;
