The experimental results indicate that, over a ranger of tube side Reynolds number and Prandtl number (Re=4000~20000, Pr=6~7.5), the internal Nusselt number and friction factor of spiral-flat tube increased by 30%-150% and 20%-50% respectively compared with smooth tube at the same Re and Pr. The value of friction factor decreases with increasing the value of B/A as well as increasing that of S/de, and the same phenomena can also be observed for Nusselt number.

实验结果表明：管内Nu和f值均随均随B/A值和S/de值的增大而减小，但随B/A值的增加而减小得更快，B/A值对螺旋扁管管内传热与流阻性能影响更大；在相同Re和Pr下，螺旋扁管管内Nu数为光滑管的1.3～2.5倍；阻力系数f是光滑管的1.2～1.5倍。

Methods Twenty-four SD rats were randomized into group A and group B with 12 rats each group. The chemicals were given by gavage. Each rat in group A was administered 2 ml distilled water once everyday, and that in group B a mixture of 30 mg/kg melamine and 30 mg/kg cyanuric acid was given once everyday.

将24只SD大鼠随机分成A组和B组，每组12只，A组大鼠每只每天以蒸馏水2 ml灌胃一次，B组每天以30 mg/kg三聚氰胺和30 mg/kg三聚氰酸联合灌胃一次。

Results: The peak responses of postprandial glucose and C-peptide were postponed; their values and the incremental area under curve of glucose responses of gruels were obviously lower than that of steamed bun (P.05). While both glycemic index and C-peptide index of steamed bun were set as 100, the glycemic index and C-peptide index of gruel A were 67, 99, and of gruel B were 57, 97 in NIDDM patients, 53, 69 in healthy subject.

结果 1。三组餐后血糖、C肽峰值显著低于馒头，血糖反应增值面积有显著性差异，以C组最低，A组最高；2.A、B两组C肽曲线增值面积显著低于C组；3.A、B、C三组血糖、C肽指数分别为67、99，57、97和53、69；4.B、C组血糖指数显著低于A组，C组的C肽指数明显低于A、B组。
