Stoots and Calabrese (1995) found that the extent of periodicity in the radial direction is from r/R = 0 to 1.7 and is controlled equally by the radial and tangential components of mean velocity, which shows very good agreement with the presented results in this study.

斯图茨和卡拉布雷斯（1995）发现，周期性程度径向方向是从R / r = 0的1.7倍和控制同样按平均流速，径向和切向元件，这项研究表明，在所提出的结果非常吻合。

Semiconductor industry has been a central figure to the economic growth in Taiwan, especially for the fabrication sector of integrated circuit that has evolved into world-leading status. The fabrication technology advances so far that the feature size (or critical line-width) of IC devices has now broken the 0.1 ?慆 barrier and into the nano-scale age. This progress discloses that the traditional definition of a "cleanroom" environment may become increasingly inadequate because prevention of particulate contamination may no longer be a critical issue. As the condensable organic airborne molecular contaminants depositing on wafer surfaces, it results in deterioration on device performance and reduces semiconductor device yield.

半导体产业已成为我国最重要的经济发展产业，其中积体电路制造技术的快速发展，使我国早已跃升成为世界晶圆代工重镇之一，然而当制程的关键线宽尺寸突破0.1微米而正式进入奈米等级之际，传统针对微粒污染控制所设计之洁净室将无法符合气态分子污染物之洁净需求，其中凝结性有机分子污染物质(organic airborne molecular contaminants)一旦沈积吸附於晶圆表面，将导致元件缺陷与制程良率下降。

Firstly, this paper studies the significance of semicon- ductor laser and analyses the product actuality of semiconductor laser constant temperature controller in country and abroad. This paper provied installation of semiconductor module and the according of component choused.
