近年来,国外高等教育评估的制度建设凸显出一些共性特征和趋势,如利益回避制度、学生参与、对评估本身的监督等。对比我国高等教育的评估主体、评估过程、评估结果、评估宗旨、评估客体等要素,需要进一步研究和重视的制度性特征或趋势... 近年来,国外高等教育评估的制度建设凸显出一些共性特征和趋势,如利益回避制度、学生参与、对评估本身的监督等。对比我国高等教育的评估主体、评估过程、评估结果、评估宗旨、评估客体等要素,需要进一步研究和重视的制度性特征或趋势可归纳为五个方面:规范评估主体,着力构建"利益回避制度";重视评估过程,探索学生参与制度;慎用评估结果,探讨评估与资源配置"挂钩"制度;反思评估宗旨,构建考评文化的调适制度;尊重评估客体,完善高等学校内部管评制度。学界已重视不同评估模式的比较研究,推进专业评价和社会评价势必成为一个新方向。 展开更多

A neuron proportion integration (PI) control strategy for semi-active suspension system of tracked vehicle was proposed based on its unique structure and the multiple and complex environment of the driving traffic. An adaptive genetic algorithm is used to optimize the parameters of the neuron PI controller. The simulation result of the neuron PI control for semi-active suspension system of tracked vehicle indicates that the vertical amplitude,pitch angle and vertical acceleration of the vehicle are well controlled. The root mean square (RMS) of the vertical amplitude decreases by 37.2%,and 45.2% for the pitch angle,38.6% for the vertical acceleration. The research of neuron PI control experiment for the semi-active suspension system of the tracked vehicle model mining in benthal indicates that the RMS of the weight acceleration vibrating along the vertical direction decreases by 29.5%,the power spectral density resonance peak of the acceleration of the car body decreases by 23.8%. 展开更多
