The results show that the Al（OH）3 solubility in sodium aluminate solution decreases with the increment of particle size, and the critical nucleus sizes increase with the rise of alkali concentration, caustic ratio and precipitation temperature. The results also imply that the presence of small particles in seeded precipitation system is an important factor to limit the depth of precipitation.展开更多

Field tests using LSSM to stabilize and green sand dunes were started in 2002. The field experiment was carded out in August 2005 when the newly formed plant community was 3 years old. The results from the comprehensive field experiment demonstrated that unlike polyvinyl acetate or foamed asphalt commonly used for dune stabilization, LSSM was plant- friendly material and could be used in combination with seeding and planting of desert species. With the help of LSSM, the desert species （i.e., Agriophyllum squarrosum （L.） Moq. and Artemisia desertorum Spreng. etc.） could be used to form community in 2-3 yeas and to stabilize sand dune effectively. The newly formed community was sustainable under an extremely dry climate condition. The organic matter and total nitrogen in the soil increased significantly as the community were formed, while the change in P and K contents in the soil was negligible.展开更多

The experimental parameters and conditions were discussed in detail. The experimental results indicated that the treatment process mentioned in this article is an effective process for the treatment of black liquor from the papermaking industry. By the treatment, the solid materials in black liquor are transferred into two by products and the other components are reused or evaporated. Thus, no wastewater except some condensation water would be discharged in pulping process and the problem of pollution of black liquor would be effectively solved.展开更多

The same finding was detected in rats that were drunk by Maotai liquor continued for 56 days. This study was to investigate the effects of Maotai liquor on the liver and its mechanism of preventing hepatic fibrosis. METHODS: After ingestion of Maotai for 56 consecutive days, male SD rats were killed for detecting the levels of metallothionein and malondialdehyde (MDA) in liver tis- sues. Rat hepatic stellate cells (HSCs) and human HSCs were cultured in vitro to observe the effect of Maotai on HSCs proliferation and collagen synthesis. After ingestion of Maotai for 14 consecutive weeks, the livers of male SD rats were harvested for pathohistological examination. RESULTS: The level of metallothionein in the liver of Mao- tai-induced rats increased by 22 folds, whereas the levels of hepatic lipid peroxide and MDA was decreased significantly ( P <0.05) in Maotai-induced animals suffering from CCl4. Maotai demonstrated obvious inhibitory effect on prolifera- tion of HSCs and the inhibition was concentration-depen- dent. Gene expression and protein secretion of collagens could also be inhibited by Maotai. In alcoholic group, typi- cal liver cirrhosis was observed. In Maotai group, however, though fatty degeneration of hepatocytes and mild fibrosis of the interstitium were observed, no obvious hepatic fibro- sis and cirrhosis were found. CONCLUSION: It might be an important mechanism of interfering the progress of hepatic fibrosis that Maotai in- creases the level of metallothionein in the liver and inhibits the activation of HSCs and the synthesis of collagen pro- teins.展开更多

In this research, the different brands of distilled spirits were identified using the pattern recognition algorithms （principal component analysis and the artificial neural network）. The recognition rates of different algorithms were compared. The recognition rate of the Back Propagation Neural Network （BPNN） is the highest. Owing to the slow convergence speed of the BPNN, it tends easily to get into a local minimum. A chaotic BPNN was tried in order to overcome the disadvantage of the BPNN. The convergence speed of the chaotic BPNN is 75.5 times faster than that of the BPNN.展开更多

In pursuit of high profits, some illegal counterfeit Moutai liquors have begun to appear in the market. Therefore, it is an urgent need for new techniques to discriminate the genuine and counterfeit Moutai liquor. In this work, the conventional Ultraviolet-Visible (UV-Vis) spectroscopy and two-dimensional correlation UV-Vis spectroscopy are applied to obtain the UV-Vis characteristic of Moutai liquor and counterfeit one, respectively. The experimental results reveal that the conventional UV-Vis spectra of the genuine and counterfeit Moutai liquor are similar. However, the two-dimensional correlation UV-Vis spectra of them are different and this method would be applied to differentiate the counterfeit Moutai liquor from the genuine Moutai liquor. Compared with conventional methods, this novel method has the advantages of easy operation, simple instrumentation and direct recognition, which make it a potential tool in the fields of food safety.展开更多
