Summary:	根據 Laplace transform schemes 算出在連續渦流的生命週期中速度、溫度和濃度的平均分佈，透過統計學隨機過程的觀念來討論子層接近模式。在黏滯子層的平均成長週期中，微粒傳遞渦流過程被自動地歸類是平均分佈，而可分析解提供了在研究懸浮微粒工程上簡單且可靠的工具，而Brownian diffusion、turbulent fluctuation、thermophoresis、and turbophoresis，對微粒自然沈澱的影響，在某種程度上可以用量化的方式表達。本研究證明了理論結果與實驗數據相類似，而在子層接近的模式中可以在可分析解中加入影響微粒自然沈澱的影響因子，藉此可延伸研究範圍與應用層面。 Mean distributions of velocity、temperature and concentration during the lifetime of successive eddies are derived from Laplace transform schemes. The comparable mechanisms of mean component that dominates the transport processes are automatically considered on the average growth period of viscous sublayer by formulating the mean distributions as a stochastic process with the aid of sublayer approach model. Analytical solution offers a simple and reliable computational tool of practical use to aerosol engineers. The effects of Brownian diffusion, turbulent fluctuation, thermophoresis, and turbophoresis on the physical trends of particle deposition rate are quantitatively revealed in some extent. The agreement with existing theoretical and experimental data validates that the sublayer approach model can further extend by including appropriate forces in the analytical formulation through the equilibrium among acceleration terms.
