当然,如果由人脑来处理这个问题,不会得出这个结论。但是由电脑来处理,就可能得出这样的结论。为了从根本上杜绝这样的错误,必须采用不同的时间坐标,而且规定不同的时间坐标之间不能互换。如果不采用多维时间,只采用一个时间坐标,就没有理由作出不能互换的规定。 最后,值得一提的是这样一个历史事实:当年非欧几何的创始人面对责难时说过,过直线外一点可以做其不止一条平行线的提法从逻辑上来说是没有任何问题的。 同样,多维时间的提法从逻辑上来说也是没有任何问题的。 5 结论 本文根据分形理论的启示,特别是关于自相似性和相似性的观点,得出结论:时间也应该是三维的。应用相对论中的洛伦兹变换,导出一种特殊情况下三维时间的具体形式,并将其改写为变维分形的形式。文中实例表明,建立多维时间的框架,不仅是可能的,在某些情况下也是必须的。最后指出,多维时间的提法从逻辑上来说也是没有任何问题的。 参 考 文 献 1 Turcotte, D.L., Fractals and chaos in geology and geophysics, Cambridge University Press, 1992 2 付昱华,流体力学中的变维分形,第二届全国计算水力学会议论文集,1993年,武汉 3 付昱华,分形技术在油气勘探应用中的改进 — 变维分形技术,中国海上油气(地质), 1994年 3期 0 Fu Yuhua, Analyzed and fractal single point method for solving hydraulic problems in ocean engineering, International meeting on petroleum engineering, SPE 29986, Nov., 1995, Beijing 5 Stephen Hawking.

While according to the views of self-similarity and similarity of fractal theory, time also should be three-dimension. With the Lorentz transformation of Relativity, this paper presents the concrete form of three-dimension time for a special case, which is also written as the form of variable dimension fractals. The examples given in this paper show that to establish the frame of multi-dimension time, not only is possible but also necessary in some case. Key words: fractal theory, variable dimension fractals, three-dimension space, three-dimension time (完) |
