基于语境、立场及视角等原因,一项概念能够指涉的对象常多于其在特定条件下所具体指涉的对象且大异于其最初含义;如此为使交流和推理便利,防止低级的逻辑错误,区分界定概念的“能指”与“所指”就显得相当必要。“法律渊源”即为一“能指”相当广 Based on such factors as context, position and perspective, a concept can refer to more than its specific object under specific conditions and its meaning is different from its original meaning; so to facilitate the exchange and reasoning to prevent low-level Logic error, the distinction between the definition of the concept of “can ” refers to the “” is quite necessary. “Law origin ” is a “can mean ” quite wide
