Urinary iodine, salt iodine, and thyroid volume(TVOL) were determined. Questionnaires were used to investigate dining places and iodine-rich processed foods. The water iodine was from the2017 national survey. Multi-factor regression analysis was used to find correlations between variables.Results Children ate 78.7% of their meals at home, 15.1% at school canteens, and 6.1% at other places.The percentage of daily iodine intake from water, iodized salt, iodine-rich processed foods, and cooked food were 1.0%, 79.2%, 1.5%, and 18.4%, respectively. The salt iodine was correlated with the urinary iodine and TVOL, respectively(r = 0.999 and-0.997, P < 0.05). The iodine intake in processed foods was weakly correlated with the TVOL(r = 0.080, P < 0.01). Non-iodized salt used in processed foods or diets when eating out had less effect on children’s iodine nutrition status.Conclusion Iodized salt remains the primary source of daily iodine intake of SAC, and processed food has less effect on iodine nutrition. Therefore, for children, iodized salt should be a compulsory supplement in their routine diet.展开更多

Mongolica) veneers caused by resin-eliminated treatment and the reversion of the color were studied. The result showed that the color of the veneers changed from buff to yellowish brown after the treatment of resin elimination and the discoloration of heartwood was more severe than that of sapwood; the degree of discoloration was significantly positively correlated with the medicament strength, temperature and resin-eliminated duration. The variance analysis showed the effects of those three factors on the discoloration were significant. With hydrogen peroxide (H2O2) as color reversion medicament and inorganic compound as medium of the reaction, the reversion of the color of heartwood was more inaccessible than that of sapwood; the degree of the color’s reversion was positively correlated with the H2O2 strength, temperature and treating time; the H2O2 concentration has significant effects on the discoloration. In order to reduce discoloration of Scot pine veneers, medicament of resin-eliminated used have to be at some low concentration, and the optimal concentration of H2O2 is 0.35% during the process of color’s reversion.展开更多
