视觉系统似乎专精于感知其他生命体，这种现象在生物运动 (biological motion)感知中尤为显著：仅用少量运动光点（点光源行走者，PLW）就能引发对运动个体的丰富感知。历经数十年数百项研究，一个核心问题始终悬而未决——这种现象究竟对生物运动有多强的特异性？

PLCs have grown in power and functional capabilities. But, small, simple PLCs are still best for replacing relays and performing other machine control functions in a minimal space. Programmable ...
