The results indicated that the range of the interline region was quite small in the total extended meniscus region,nevertheless the variation of its surface temperature was much obvious,implying that the resulted Marangoni effect could cause great "pump" force to drive the film flow,which may be the main contribution of the interline region to the total extended thin film evaporation.

The comparisons of biochemistry between OP and OR rats The differences between OP and OR rats included not only body weight, but lipids metabolism and insulin sensitivity as well, characterized with insulin resistance, increasing in serum free fatty acids and ketone body, and hepatic TC and TG in OP rats. However, no significant differences were observed in serum TG, TC, LDL, HDL and fasting glucose between OP and OR rats.⑶Comparisons of metabolites in serum, urine and liver tissue between OP and OR rats①There were significant differences in amino acids concentration between OP and OR rats,especially in liver tissue, such as high concentrations in ketogenic and glucogenic amino acids in OP rats, suggesting differences in amino acids metabolism;② The different metabolites between OP and OR rats included increasing of various saturated fatty acids and decreasing of polyunsaturated fatty acids in OP rats;③The urinary metabolites analysis indicated that different structure or metabolism of gut microflora might exist between the two phenotypes, which probably influenced the regulation of body weight gain;④The end-products of catecholamines in urine and intermediates of krebs cycle in serum in OP rats were all up-regulated, suggesting that the activity of sympatheic nervous system and energy metabolism was higher in OP rats than OR rats.

And 0.4～0.6 respectively for the induction coil with round crosssection and rectangular cross-section; The magnetic flux density of coil made with round pipe was nonuniform, especially near the inner wall of coil turns that caused a fluctuation of electromagnetic pressure on the surface of liquid metal and had a bad effect for forming a sample with uniform cross-section and smooth surface; The system of screen and restraint magnetic field not only had an efficient effect on restraining the electromagnetic stirring and stablizing meniscus, also caused the conecial periphery of melt to be vertical; The position of top and S/L interface of melt had a direct effect on the meniscus shape. The meniscus profile varied from cone-shaped through column to cucurbituceous shape with the increase of top height or decrease of S/L interface.
