野生动物学报, 2020 以上海动物园人工哺育的11只幼獐（雄性3，雌性8）为研究对象，收集1—15周龄的体重（Y）、体长（X2）、前后足长（X5，X4）、肩高（X1）、胸围（X3）、耳长（X6）和尾长（X7）8项体尺数据。利用SPSS 18.0计算各体尺的平均值，对所选8项体尺进行相关性分析，建立幼獐的体重增长模型，并对影响体重较大的几项体尺构建回归方程。采用经典动物增长非线性Logistic、Gompertz、von Bertalanffy函数模型和Gauss、幂函数、指数函数对人工哺育幼獐体重生长曲线进行拟合 ...

Gaoya dianqi, 2021 在GIS气体绝缘状态评估过程中,不同的权重确定和隶属度函数选择方法会导致评价结果的不同,进而影响评价结果的准确性。为了避免主观因素的影响,文中在利用熵权法确定权重的基础上,根据变权综合理论引入均衡函数来调整各评价指标的权重。此外,采用梯形、Γ形以及k次抛物线型相结合来确定各指标的隶属度函数,以避免单一隶属度函数所造成的评价误差。最后,利用综合诊断模型来确定GIS气体的绝缘状态,并对比常权重和单一隶属度评价结果。实例分析表明,该方法可以准确有效的评估GIS设备气体的绝缘状态。

政府旅游数据开放的评价指标体系构建与组态分析：基于21个省级行政区的数据
大数据在信息时代和智慧旅游背景下，政府主动对外开放内部的旅游数据，有利于充分释放旅游数据资源的商业价值与社会价值。使用变异系数法与熵权法进行组合赋权，构建了政府旅游数据开放评价指标体系，计算21个省级行政区的具体得分，并采用模糊集定性比较方法进行高评价值与低评价值条件组态分析。结果表明：指标体系包含4项一级指标、17项二级指标与51项三级指标，可以对当前省级行政区的旅游数据开放绩效进行有效评价；利用层、数据层是权重较高的一级指标，法律政策效率与内容、平台关系等是权重较高的二级指标；高评价值组态为综合发展型 ...
