破碎体分形及其筛分布

以分形理论为基础．讨论了破碎体分形的一些实际问题及其与筛下，筛上分布一致的条件．及维数Ｄ＞３的问题．证明：只有粒级的尺度范围足够宽时，分形分布才有可能与筛下或筛上分布一致；且Ｄ＜３时。与筛下分布一致．Ｄ＞３时，与筛上分布一致．Ｄ＞３的实际粒级可能是理论破碎粒级丢失粗粒或侵入细粒的近似结果，也可能反映了理论破碎模型的不完善性．

Fragments Fractal and its Sieve Distribution

Based on the fractal theory,this Paper gives a discussion about some practical problems in fragments fractal,together with its required conditions to be in line with the distribution of the Percentages retained or passiug,and the question of the dimension D>3.It also gives a demonstrition of the following Points:only When the range of scale is wide enough,the fractul distribution is capable of being in line with the distribution of Percentages reclined or asssings furthemore,when D<3,the fractal distribution is in line with the distribution of percentages passing,and with that of percentages retained when D>3.The actual gtadingr when D>3,may be the approximate results of the theoretical fragments losing some of coarSe articles or getting in some of fine articles,otherwise it may reflect the imperfeotability of the theoretical fragnentution P8ttern.
