[Method] Based on the amino acid sequence, the physical and chemical properties, hydrophilicity/hydrophobicity, secondary structure of ZnT from Baoding alfalfa were predicted by a series of bioinformatics software. And the transmembrane domains were predicted by using different online tools. [Result] ZnT is a hydrophobic protein containing 408 amino acids with the theoretical pl of 5.94, and it has 7 potential transmembrane hydrophobic regions. In the sec- ondary structure, co-helix （Hh） accounted for 48.04%, extended strand （Ee） for 9.56%, random coil （Cc） for 42.40%, which was accored with the characteristic of transmembrane protein. [Conclusion] mZnT is a member of CDF family, responsible for transporting Zn^2＋ out of the cell membrane to reduce the concentration and toxicity of Zn^2＋.展开更多

[Method] Using fluor reagent spec- trophotometry, fluoride concentration in the atmosphere in spring and winter of Baoding City was detection, and its air pollution by fluoride was assessed. [ Result ] In winter, atmospheric fluoride concentration in Baoding City was 0.009 -0.052μg/L, and the average detected rate of atmospheric fluoride concentration in the campus of Hebei University was 80%, In spring, atmospheric fluoride concentration was 0. 018 -0. 059 μg/L, and the detected rate was 94%. Compared with winter, air ＇pollution by fluoride was more serious in spring. During a day, the peaks of fluoride concentration in the atmosphere appeared from 10：00 to 11：00 or at 14：00. A rain could reduce fluoride concentration in the atmosphere and make the air clean. [Condusion] The research could provide scientific references for the effective control of air pollution by fluoride in Baoding City.展开更多

With more and more attention attached to the quality of the air environment,it is imminent to analyze the future development trend of air quality. In this paper,the grey correlation analysis was used to determine the weights of 6 pollution indexes,namely PM10,PM2. 5,SO2,NO2,CO and O3. The fuzzy comprehensive assessment method was applied to determine the air quality eigenvalues H（ 2. 145,1. 926,and 1. 805） of Baoding City in 2014-2016,suggesting that the air quality in Baoding is getting better and better. In addition,the grey forecasting model GM（ 1,1） was used to forecast and test the air quality of Baoding City. The results show that the prediction is good.展开更多

According to the surveys, per capita net income level of the villages maintained consistent growth, as indicated by survey data on the years of 1930, 1936, 1957, 1986 and 1997, except for 1946 which saw decline, and enjoyed rapid growth particularly in the years of reform and opening-up after 1986. The changes reflect the national trendsustained decline of the proportion of net income from household operations versus eontinuous growth of the proportion wages income takes of the whole income.展开更多

On the base of the abundant compressions and laboratory studies, the author complemented some new data of the cuticular characters of the speeies Cordaites baodeensis Sun for its study of taxonomy. Meanwhile, the author newly discovered a number of sporopollen fossils associated with the mega-plants of Cordctitales, described 9 species of 6 genera. The palynological data can provide a supplement evidence for defining the age of C. baodeensis and its associated plants to be Early Permian.展开更多
