一、绪言众所周知,对于地球以及包围它的外层宇宙空间的利用,很早就被提到议事日程上来,并且正在得到逐渐的开发,特别是在这十几年来,宇宙空间的开发利用取得了惊人的进展。相比之下,对于地球内部,就是说对地下及海洋的开发利用则相差甚远。为了研究而进行的勘探方法,虽然已经深入地下数千米,而实际的利用范围尚未超过数百米。仅就地下空间的利用来说,还局限于所谓的地表面以下。在英语里称之为:“Subsurfce”的地壳的极表层部分。与广大的字宙空间是不能相比的。相比之下,对地下及海洋的利用之所以困难,其主要 I. INTRODUCTION As we all know, the use of the Earth and the outer space surrounding it has long been mentioned on the agenda and is being gradually developed. Especially in the past ten years, the development and utilization of space has been achieved. Amazing progress. In contrast, for the interior of the earth, that is to say, the development and utilization of underground and oceans are far from one another. The exploration methods carried out for the purpose of research, although it has penetrated several kilometers underground, and the actual use range has not exceeded several hundred meters. The use of underground space is only limited to the so-called ground surface. In English it is called: “Subsurfce” is the very surface layer of the crust. It cannot be compared with the vast space of characters. In contrast, the use of underground and marine resources is so difficult
