The highest heat transfer coefficient for air flowing in the nine 3-D IFT with staggered arrangement fins is No9 tube. In the turbulent region, the heat transfer coefficient of No9 tube is a factor of 10.36 compared with smooth tube, and its thermodynamic performance coefficient is as high as 6.49; The average Nusselt number in the most superior 3-D IFT with staggered arrangement can be increased by about 1.04 times in the laminar flow, and 6.38 times in the transitional flow as compared with that in the smooth tube. The friction factor between fluid and tube wall can be 0.96 times in laminar flow, and 12.68 times in transitional flow as compared with that inside the smooth tube.

The result show that the position of free surface is higher because of frusta of brake, especial obvious in the head of frusta of brake; flux coefficient and pressure on dam are quite influenced by type of frusta and 3 A type frusta of brake relative to 2 type frusta of brake has bigger flux coefficient and smaller pressure on dam; Obvious influence of ability of discharge flow for different ratio of thickness of frusta and breadth of brake and pressure on dam reduces with increasing ration of thickness of frusta and breadth of brake, while bigger flux coefficient is obtained when tlb = 0.2.(7)The 3D free surface turbulent model established in the paper is comparatively well and truly simulates 3D flow over spillway with frusta of brake and series waterpower computation can be completed aim at different type of dam, type of frusta and disposal on the dam and different water height on peak of

结果表明，闸墩河海大学博士论文的存在抬高了水面线的位置，其中在闸墩头部尤其明显；墩型对流量系数和坝面压力影响较大，3A型闸墩相对于2型闸墩具有更大的流量系数和更小的坝面压力：不同的墩厚闸宽比t/b对泄流能力也将产生显著的影响，随着墩厚闸宽比的增加，坝面压力降低，而当t/b二0.2时溢流坝具有更大的流量系数。7本文建立的三维自由面湍流场模型能够比较准确地模拟带闸墩溢流坝三维过坝水流湍流场，可以针对不同的坝型、墩型、坝面布置形式以及不同的坝顶水头完成系列水力计算，为泄水工程建筑物的设计提供可靠的分析依据

Although translator has turned from being a crystal ball by which the original culture can unrestrainedly penetrate to another crystal ball by which the target culture can freely traverse, the translator's personal embodiment, in the process of cognitive act, are still absent in translation studies. Translators are still subjects without body or simply disembodied subjects.
