对成年雄性斑胸草雀听觉剥夺引起鸣曲声谱结构和音节参数的变化进行分析,利用焦油紫染色等方法,检测了听觉剥夺对LMAN核团平均面积、体积和核团内的细胞面密度的影响。成年雄性斑胸草雀致聋后14 d,声谱结构出现畸变,音节的熵值和熵值变... 对成年雄性斑胸草雀听觉剥夺引起鸣曲声谱结构和音节参数的变化进行分析,利用焦油紫染色等方法,检测了听觉剥夺对LMAN核团平均面积、体积和核团内的细胞面密度的影响。成年雄性斑胸草雀致聋后14 d,声谱结构出现畸变,音节的熵值和熵值变异数均发生显著变化,表明斑胸草雀成年后稳定的鸣曲需要听觉反馈来维持,失去听觉导致致聋鸟变成聋哑鸟。同时LMAN核团的平均面积和体积有明显减小的趋势,LMAN核团内的细胞面密度下降,说明了致聋导致鸣唱行为的畸变,可能与致聋所导致其脑内发声学习通路中的输出核团-LMAN核团退化有关,该结果为探究LMAN核团在鸣禽发声系统中的功能和揭示致聋后聋哑变化可能的机理提供了理论参考。 展开更多

The narrow definition of the digital power system (DPS) is proposed. The architec- ture, features and key contents of the DPS are presented, which include intelligent dispatching system, hybrid automatic control system and data sharing platform. The successful construction of the DPS can greatly improve the performances of power system operating and dispatching, which mainly reflect a fundamental in- crease of the ability of avoiding catastrophes resulting from blackouts of power supply, a significant improvement of economic efficiency of power system opera- tion, and an improvement of decision efficiency of power system developing. The DPS describes a vision of the development of power system and the way to achieve this vision. At the same time, the paper also proposes the principles of the design and implementation of the DPS. 展开更多
