一个世界上最深,钻探费用最高的洞不久将在联邦德国开钻。这个洞将被钻入地壳以下十四公里,拟在一九九五年完成。这个洞在地面上的直径为八十厘米,逐渐深入到最深点时的直径为二十八厘米。科学家们希望它帮助了解地壳的详细结构,得到更多有关地球的内部以及四十亿年来造成地壳形状的各种原动力资料。
One of the deepest and most expensive holes in the world will soon be drilled in the Federal Republic of Germany. The hole will be drilled into the crust 14 kilometers below, to be completed in 1995. The diameter of the hole on the ground is eighty centimeters and the diameter at the deepest point gradually reaches twenty eight centimeters. Scientists hope it helps understand the detailed structure of the crust and get more information about the dynamics of the Earth’s interior and the shape of the earth’s crust for billions of years.
