在公元前1000年至公元1000年之間，由印度數學家所寫的各種數學論文首次闡明了出來，零的概念，代數和運演算法則的技巧，平方根與立方根都闡明了出來。 -
The present results indicate that the diamond element always yields the highest heat transfer, followed by cube and waterdrop pin - fin. however, the pressure drop for the diamond pin is higher compared to the cube and waterdrop pin - fin. arrays with geometric parameters x / d = 2. 7 elements generally cause the greater heat transfer and pressure loss than those with x / d = 3. 3 and x / d = 4
研究結果表明：鉆石形擾流柱排換熱最強，方形次之，液滴形最弱，相應地鉆石形擾流柱排壓力損失也最大，方形次之，液滴形最弱；小間距（ x / d = 2 . 7 ）在換熱較強的同時壓力損失也高於其他兩種間距。 -
In chapter 4 we obtain the helly number for hyperplane transversal to translates of a convex cube in r ~ ( d ). where we prove that the helly number for such families is 5 when d = 2, and is greater than or equal to d + 3 when d 3
在第4章中我們探討了o中超平面橫截單位立方體平移形成的集族的heily數，證得碑中此heily數為5 ，在呼中此heily數z民並推廣至呼，在胸中此heily數d 3
