  • Battles increasingly depended on new military technologies such as radar and the proximity fuze.

    战斗越来越依赖雷达和近炸引信等新型军事技术。

  • Airborne technologies, such as different types of radar and photographic equipment carried by airplanes or spacecraft, allow archaeologists to learn about what lies beneath the ground without digging.

    航空技术,例如由飞机或航天器搭载的各类雷达和摄影设备,使考古学家无需挖掘就能了解地下埋藏着什么。

  • Ground surveys allow archaeologists to pinpoint the places where digs will be successful. Most ground surveys involve a lot of walking, looking for surface clues such as small fragments of pottery. They often include a certain amount of digging to test for buried materials at selected points across a landscape. Archaeologists also may locate buried remains by using such technologies as ground radar, magnetic-field recording, and metal detectors. Archaeologists commonly use computers to map sites and the landscapes around sites. Two- and three-dimensional maps are helpful tools in planning excavations, illustrating how sites look, and presenting the results of archaeological research.

    地面勘测使考古学家能够准确找出可以成功发掘的地点。大多数地面勘测需要大量步行,寻找诸如陶器碎片之类的地表线索。勘测通常还包括一定量的挖掘,在一片地域中选定的若干地点检测是否有埋藏物。考古学家还可以利用地面雷达、磁场记录和金属探测器等技术来确定地下遗存的位置。考古学家通常用计算机绘制遗址及其周边地貌的地图。二维和三维地图是规划发掘、展示遗址面貌以及呈现考古研究成果的有用工具。
