It firmly grasps the " bull nose"( key part) of the project,energetically implements the construction of 100 modern circular agricultural demonstration parks,100 agricultural leading enterprises with output value of 100 billion yuan,and 100 agricultural new business model demonstration projects( hereinafter referred to as 300 Demonstration Projects),to realize the goal of the output value of the modern agriculture industrial clusters of Nanchong City exceeds 100 billion yuan in 2020.展开更多
为工业企业听力保护计划制定、人机工程学设计及劳动者烦恼度缓解等提供客观的生理依据,分析了生产性噪声对工作人员脑认知的影响.采集自愿者在90 d B(A)的稳态机械性噪声刺激以及安静状态下的脑电信号,建立事件相关脑电位ERP中N1(N100...为工业企业听力保护计划制定、人机工程学设计及劳动者烦恼度缓解等提供客观的生理依据,分析了生产性噪声对工作人员脑认知的影响.采集自愿者在90 d B(A)的稳态机械性噪声刺激以及安静状态下的脑电信号,建立事件相关脑电位ERP中N1(N100)波的幅值脑地形图及P2(P200)波幅值的脑地形图,对ERP信号进行时频分析.结果表明噪声刺激与静音状态相比,ERP在N1波的幅值明显减少,而在P2波幅值变化呈相反趋势明显增加.噪声刺激下被试额区导联的N1幅值显著减小,P2幅值显著增加,表明高声压级生产性噪声导致被试烦躁、注意力分散,并干扰了认知能力.展开更多
