Methods of expert interview,literature,questionnaire,case study,and mathematical statistics are used to analyze the annual competition frequency,events participated and other issues of China\'s elite swimmers.

The experiment results indicate that zinc volatilizing rate is greater than 95%,lead volatilizing rate than 97%,under the conditions of coal rations 50% of slag mass,reduci.

The secondorder function of volatility of mould powder base (CaF_2CaOSiO_2Na_2O) with basicity, Na_2CO_3, CaF_2, temperature and time has been established through orthogonal design.

When the modified basicity of the slag R ′>1 and contents remain constant, volatility is raised greatly only when temperature exceeds the flow temperature; when temperature remains constant, volatility increases with basicity and Na 2CO 3; when R ′<1.

The relationship of the volatility of Ternary Flux CaO SiO 2 CaF 2 to temperature and the slag composition was studied using losing mass method.

The volatilization rate constants increase with increasing pH and temperature in water,and are larger in high wind speed above water surface than in tower wind speed.

A good positive correlation between the gas-seawater partition coefficients and the measured volatilization rates of OCPs is observed.
