【美国《能源与技术评论》1984年7期第18页报道】在典型的地下核试验中,各种诊断仪器要通过几条准直管对核试验进行测试。要得到高质量的数据,某些仪器必须与实验所要测试的部分很精确地保持直线。安放诊断仪器的保护罐是很大的(长34米,直径2.5米),也相当笨重(有时重达200吨),当安装孔被回填后,它被埋在成千上万吨的 【Comment on Energy and Technology, 1984, No.7, page 18】 In a typical underground nuclear test, a variety of diagnostic instruments are required to conduct nuclear tests through several collimators. To get high quality data, some instruments must be very straightforward to the part of the experiment to be tested. The protective tank for the diagnostic equipment is large (34 meters long, 2.5 meters in diameter) and also quite bulky (sometimes weighing up to 200 tons). When the mounting hole is backfilled, it is buried in tens of thousands of tons
