本論文旨在探討應用液動壓拋光法(HDP)進行拋光時其非等向性拋光特性對工件所產生的拋光行為是否與磨粒的運動方向有關係。研究中將進行兩種類別實驗，第一類實驗，是針對原始表面為等向性表面粗度的工件進行拋光，觀察其在五個方向上的粗度移除效率隨著角度的變化。第二類實驗，則針對原始表面為非等向性表面粗度的工件進行縱向、橫向、斜向粗度拋光，觀察各粗度移除效率的變化。並且兩類實驗都進行假設檢定判斷移除效率的差異是否顯著。

對於等向性表面粗度的實驗結果以假設檢定來檢定時，皆無法推翻假設。至於非等向性表面粗度的實驗結果，假設檢定幾乎都被推翻。於是提出理論分析討論影響粗度移除效率的因素，來解釋非等向性表面粗度拋光時所遇到的困惑，其原因可能為不同的潤滑效應所造成。以潤滑理論中不同型態的表面粗度對潤滑效應所產生的影響來驗證所提出的解釋能夠適用。並以實驗結果的迴歸分析，來說明理論與實驗的一致性。

由實驗的結果與理論的分析可以得到結論: 液動壓拋光法之非等向性拋光特性對工件產生的拋光行為可能與磨粒運動方向無關。

This study is to investigate that the polishing behavior will be independent of or dependent on the direction of particle motion by the anisotropic polishing phenomenon of hydrodynamic polishing process under the semi-contact lubricating condition. There are two types of experiments to be examined to get to the objectives. First, taking polishing on the work surface which possesses the isotropic surface roughness, to discuss the variation of the smoothing efficiency of the surface irregularities in the five different directions on the work surface. Second, taking three kinds of polishing, “longitudinal, transverse, and oblique roughness polishing”, on the work surface which possesses the anisotropic surface roughness. Then to discuss the variation of the smoothing efficiency of the surface irregularities on the work surface.
Both the results of two types experiments should be take to distinguish
the difference between one smoothing efficiency and the others from
using the hypothesis testing.

All hypothesis tests about the experiment results of the work piece which possesses the isotropic surface roughness are accepting .
But, most hypothesis tests about the experiment results of the work piece which possesses the anisotropic surface roughness are rejecting .
The theory analysis about the smoothing efficiency is discussing. The discussion about the smoothing efficiency can explain the phenomenon due to taking polishing on the work surface which possesses the anisotropic surface roughness. The reason why the phenomenon happened is possible the effects of different lubrication condition. Last, from the lubrication theory, the effects of different lubrication condition due to different surface texture can be employed to verify the explanation about the phenomenon is suitable.

The conclusion from the experiment results and the theory analysis
is: the polishing behavior is possible independent of the direction of particle motion by the anisotropic polishing phenomenon of hydro- dynamic polishing process under the semi-contact lubricating condition.
