无究尽的多种多样的生命形式,表现着无限对外界环境的适应能力。杰出的苏维埃学者Б.И.维尔诺得斯基院士创立的“生物圈”学说,已论及无机物的地壳中,存有着生命物质这一事实。他在“生物圈”那本书里,首先提出了生物圈的界限问题,也就是生命存在的区域问题。可是,这些界限究竟在哪裹呢? 细菌孢子和微菌的踪迹所能及到的地区,是非常广泛的。它们的旅程可以高到33,000公尺, A variety of life forms that are not exhausted show a limitless ability to adapt to the external environment. The “Biosphere” theory founded by the distinguished Soviet scholar Prof. Vilnodowski, has discussed the fact that there are living things in the earth’s crust. In his book “The Biosphere,” he first proposed the boundary problem of the biosphere, that is, the regional problems of life. However, where exactly are these boundaries? The areas where bacterial spores and micro-organisms can be found are very extensive. Their journey can be as high as 33,000 meters.
