Now we may discuss the effects of angular orientation upon physical laws . 現(xiàn)在我們來討論角方位對物理定律的影響。
The temperature distribution of the aluminum film and polymethyl methacrylate substrate are obtained in radial orientation and angular orientation at various time 采用鋁薄膜和有機玻璃為基底的慢基底快涂層式組合,分別得到了不同時刻薄膜鋁和基底有機玻璃中的溫度場隨徑向和周向的分布曲線。
In a typical lay - up , the angular orientation of the fibers in each layer , or lamina , is specified so that the resulting composite has certain desired mechanical and material properties 在一個典型的間隔里,每層或每片的纖維角定向就確定了,這樣處理的合成物具有特定要求的機械和材料性能。
The difference of temperature fields from considering and neglecting the temperature - dependence of material parameters is compared , and the temperature distributions of al pipe are obtained in angular orientation at various time 給出了溫度隨角向的分布曲線,比較了物理參數(shù)隨溫度變化和不隨溫度變化兩種情況下溫度場的區(qū)別,并進一步得到了近場區(qū)域表面波的時域波形。
The numerical results indicate that the temperature rise in the substrate is much smaller than that in the film if the thermal conductivity of the film is much larger than that of the substrate , and the range in angular orientation where meaning temperature rise in film is very small besides the range of laser irradiation 計算結(jié)果表明:如果薄膜的熱擴散系數(shù)遠大于基底的,則基底中的溫升遠小于薄膜中的溫升,可忽略不計;薄膜中沿周向除了激光輻照范圍外,有意義的溫升范圍很小。
