n.名词
frontier, bound这两个词都指“分界线”。frontier指一个国家邻近另一个国家边境的领土或未开发的地区、领域; bound可指国家、地区等的“边界”,也可指思想领域、法律、科学界等的“界线”“限制”“限制范围”。 border，bounds，boundary，frontier，limit这些名词均含有“边界，边境”之意。 border多指国与国之间或两地区的分界处，即分界线附近的边缘部分。 bounds常与boundary换用，指土地边界，但意思不如boundary明确，主要用于抽象事物和文学作品中。 boundary侧重地图上正式标定的、双方遵守的边界，也可指较小行政单位间的界线。 frontier指两国接壤的前沿地区，属于各国的国境和边疆，多指设防的边界。 limit含义广泛，常用作复数。指任何界限、范围、分界线外面的部分，可指有形或无形的东西。 来源于拉丁语名词fons, fontis, m前,经由古法语frontiere进入英语为frontier。
