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.

To replace a overflow pipe made from cast iron with the service life of two months, the composite tapered pipe with one end diameter of 180mm and another of 220mm and height of 500mm has been applied in a ore dressing plant for almost one year, and it is still in service now.

某选矿厂使用白口铁溢流管（φ180mm—φ220mm×500mm），寿命为2个多月，改用内衬陶瓷的灰口铁溢流管，已使用了近1年，现仍在继续使用。

One anastomotic leakage patient operated again in Hartmans' way because of huge anastomotic leakage and sepses symptom;another patient went out of the hospital with the conduct-pipeline of antesacrum because of incurable leakage through intestinal nutrition,TPN and conservative treatment,its leakage was curable after two months;another patient appeared the leakage of rectal vagina which was remedied after six months;the other 20 anastomotic leakages were recovered by conducting, local washing,taking food,treating accompanying illness.

结果 263例中发生吻合口瘘23例，占8.7%。1例吻合口瘘口大，出现全身中毒症状再行Hartmans手术；1例吻合口瘘经肠内营养、肠外静脉营养等保守治疗，瘘口未愈，带骶前引流管出院，2个月后愈合；1例出现直肠阴道瘘，6个月后行阴道修补术；其他20例吻合口瘘经骶前引流、冲洗、加强营养、伴随疾病治疗均痊愈出院。
