  1. An empirical analysis is made with the population data of the us cities to verify the theory and models developed in this paper, which will contribute to reconcile the apparent difference between the hierarchical step - like frequency distribution of city sizes suggested by central place theory and the smooth curve reflected by the work on the rank - size rule

    多重zipf維數模型不僅可以有效地統一中心地的等級階梯與位序-規模法則反映的連續分佈，而且可以揭示城市體系演化的更多信息和隱含法則。以美國城市體系1998年的數據為實證對象，給出了城市規模分佈的多分維
  2. After analyzed the basic principle of optimized noise reduction on tyre pattern, summarized three approaches to noise reduction. the first is trying to reduce size of single block or socket to reduce noise amplitude on time domain, the second is to adjust stripes sorting order and their interlace value to avoid noise - made by every single block - peak values on time domain overlayed and the last is to adjust ratio of blocks and sockets, ratio of stripe interval and stripe sorting order to avoid noise periodical distribution and abnormal high peak values in some frequency strip

    論文第四章分析了輪胎花紋優化降噪的基本原理，總結出三條降噪途徑：在允許范圍內盡量減小單個塊或槽的大小、刻刀槽軟化花紋塊來減小噪聲時域波幅度；調整節距排列順序、花紋條之間的錯位值，使各發聲單元發出的聲壓時域波形的同向峰值錯開，避免同向峰值疊加；調整花紋塊和槽比例、節距比例、節距排列順序，盡量避免周期性分佈，使輪胎所發出的噪聲趨于白噪化，避免某些頻段的異常高峰值。
