    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。
  5. Based on the theoretical analysis and experimental researches, it is presented that the wider spectra are resulted from the many fluorophores with large numbers of vibrational energy levels on the ground level in the blood cells, and the reduction of the spectral intensity is due to the reabsorption of the blood cells and the energy transfer of the collisions between the fluorophore and another one or other macromolecule. on the other hand, when the concentration of the blood cells is increased, the reabsorption of the blood cells, the secondary fluorescence due to the reabsorption and the influence of the concentration on the energy levels of fluorophores are all the factors of the red - shifted spectral peaks

    在進行理論分析和研究的基礎上，提出了因血細胞中存在多種熒光團，且這些熒光團的電子能級上又存在大量的不同的振動能級，從而導致被激發的熒光團發出較寬的熒光光譜；血細胞濃度的增大，熒光團以及其他大分子之間的距離變小，造成它們之間因碰撞的能量轉移概率加大，因而易產生熒光猝滅，結果導致熒光強度的變小；血細胞溶液中重吸收所導致的熒光猝滅和二次熒光發射，以及血細胞濃度的變化對其中熒光團能級系統的影響都是導致熒光峰值波長「紅移」的原因；進而研究了led光誘導血細胞產生熒光光譜的機理。
