The imported transparent glaze fired at lower temperature was analysed semi - quantitatively by adopting emission spectroscope. the stripping of lead and cadmium from this transparent glaze fired at lower temperature in ceramic product was determined by atomic absorption spectroscope. the effect of chemical composition on the stripping of lead and cadmium was analysed. upon the author s opinion, the overproof lead stripping from the imported transparent glaze fired at lower temperature can only be settled by adopting lead - free glaze instead of adopting low - lead prescription. the author succeeded in developing an excellent lead - free transparent glaze fired at the lower temperature of 1000 1050. the success is based on an inquiry into the feasibility of using such new agents of fusion as li2o and sro in replacement of pbo ; and on a study of the effects of the contents of sio2 ， al2o3 ， b2o3and other metallic oxides on such performances of glaze as coefficient of linear expansion, fusion temperature and transparency. it is also based on an analysis of coefficient of linear expansion of blank and glaze on an analysis of coefficient of linear expansion of blank and glaze on their correlation ; and on a study of technology for preparing glaze

Particle ratios embody the chemical equilibrium driven by inelastic interaction during rapid expansion when the temperature decreases in the colliding system, the measured hadron ratios provide the chemical composition of the fireball at the chemical freeze - out point and access the baryon transporter stopping ) for the initial conditions at early stage of the collisions. in this paper, we study the anti - proton to proton ratio from ig7au + 197 au collisions, analyzing p / p ratio as functions of rapidity, transverse momentum and centrality at ^ / saw = 200gev and the dependence on the center of mass energy of p / p ratio, compared with the experimental results. it shows that the p / p ratio has n ' t obvious dependence on rapidity for mid - rapidity, but shows a slight increase trend with pt increasing in the range of pt < 1gev / c for mini - bias or central collisions, and rqmd shows a more remarkable correlation between p / p ratio and centrality than experiments do at snn = 200gev
