野生动物学报, 1986 对猕猴等灵长类动物自然种群生态学的研究过程中,都有赖于接近动物,有赖于对个体的识别,这就提出了人工半驯化和个体标志问题。人工半驯化猴群不仅方便生态学观察研究,也有利于保护动物,及时掌握动物资源消长情况,有利于开展科学研究和合理利用动物资源。一、猕猴的人工半驯化最早对灵长类动物的自然种群进行人工半驯化的是英国灵长类学家珍尼·古多尔,她于六十年代初在非洲研究黑猩猩时就是利用所谓的“香蕉俱乐部”来引诱接近黑猩猩的。她利用黑猩猩大卫不畏人的特点。对大卫重点开展工作。以让其起到带头作用。加速接近黑猩猩 ...

Dianci bileiqi针对不对称谐振接地配电网传统故障保护启动方式感知过渡电阻的能力薄弱以及故障选线困难问题，提出了一种计及不对称度的单相接地故障保护复合启动及选线方法。首先，利用零序电压变化量构造保护预启动判据，发现将其整定为3%的相电压时，能准确感知高阻接地故障，但易受配电网运行方式改变的影响；其次，在对谐振接地配电网正常和故障运行状态线路零序电流分析发现，健全线路的线路零序不平衡电流差为0而故障线路零序不平衡电流差为故障相电压与过渡电阻的比值，根据这一显著差异进而得到故障保护复合启动及选线判据 ...
