Based on the model of irreversible cluster-cluster aggregation, a principal possibility of predicting and simulating the degree of aggregation of filler particles, mathematically expressed by the size distribution of aggregates, is shown.
      
The algorithm is based on Diffusion-Limited Cluster-Cluster Aggregation in which larger particles hinder the DLCA.

With the breeding plan for sugarcane, eight families of F_1 population were studied beginning in 1982. Cluster analysis as well as principal component analysis were performed according to their genetic distanes, Results showed that classification with the two quantities aro quite similar. Among F_1 population family 1 and 4 are placed under the similar cluster (cluster Ⅰ). Family 3, 7, 2, 6, 5 and 8 are placed under another cluster (clusterⅡ).

With the breeding plan for sugarcane, eight families of F_1 population were studied beginning in 1982. Cluster analysis as well as principal component analysis were performed according to their genetic distanes, Results showed that classification with the two quantities aro quite similar. Among F_1 population family 1 and 4 are placed under the similar cluster (cluster Ⅰ). Family 3, 7, 2, 6, 5 and 8 are placed under another cluster (clusterⅡ). For the same cluster, the families are very close in thear genetic distances although many generations of them came from quite different countries and regios belonging to different geographical sites. Howevor, they belong to a group with closely related clones, with genetic effects more or less similar. Thus, it can be considered that the different families falling under the same cluster are in tact the repoated hybrids of the same group.

从1982年甘蔗育种计划中选取8个家系的F_1群体,根据它们的遗传距离进行聚类分析和主分量分析,结果表明,两种数量分类方法效果相当一致。家系1和4两个F_1群体被归入一个聚类(Ⅰ),家系3,7,2,6,5和8被归入另一聚类Ⅱ。发现一些家系,虽然来自地理位置十分不同的国家和地区,但是它们的遗传距离很近,可看作是血缘相近的、亲缘效应大体相似的无性系,并可划入同一聚类。初步认为聚类内的不同家系实际上是同一组合的重复杂交。

According to the fractal theory, the result of experiment on gold cluster growth obtained by M A Listvan(Determination of time dependence of domain growth by direct observation of small metal cluster. Surf Sci, 1986, 173: 294-309) is discussed in detail. Through analysis, the authors find that the cluster-cluster growth process is an important form for the growth process of ultrafine-particles, which is described in literature, indicated in above brackets, and there is very good fractal self-similarity...

According to the fractal theory, the result of experiment on gold cluster growth obtained by M A Listvan(Determination of time dependence of domain growth by direct observation of small metal cluster.

Through analysis, the authors find that the cluster-cluster growth process is an important form for the growth process of ultrafine-particles, which is described in literature, indicated in above brackets, and there is very good fractal self-similarity property in these growth procesc.

根据“分形”理论,对在M.A.Listvan的文章(Detemination of Time Dependence ofDomain Growth by Direct Observation of Small Metal Cluster.Surf Sci,1986,173:294—309)中所提出的小金粒子生长实验结果作了深入研究.研究结果发现,金超微粒的生长过程是以集团-集团生长为主要形式的生长过程.而且这种生长过程具有很好的自相似分形特征.

Although there are, mass conservation criterion and the second moment criterion et al. for judging the sol-gel transition in the irreversible cluster-cluster aggregation systems, it is not so convenient for to do it. In this paper, a new criteriou for the Swsystem is given. This new criterion makes it possible to judge whether the phase transition occurs, as well as to the point of the phase transition easily.

关于集团—集团不可逆聚合系统的sol-gel相变,虽有质量守恒判据和尺寸分布函数二次矩判据等可供判断,但这些判据使用起来往往不太方便。对s~ω型系统提出新的判据,根据新判据,不但容易判断系统能否发生相变,还可以较方便地计算出相变点。
