  3. 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

    在進行理論和研究的基礎上,提出了因血細胞存在多種熒光團,且這些熒光團的電能級上又存在大量的不同的振動能級,從而導致被激發的熒光團發出較寬的熒光光譜;血細胞濃度的增大,熒光團以及其他大之間的距離變小,造成它們之間因碰撞的能量轉移概率加大,因而易產生熒光猝滅,結果導致熒光強度的變小;血細胞溶液所導致的熒光猝滅和二次熒光發射,以及血細胞濃度的變化對其熒光團能級系統的影響都是導致熒光峰值波長「紅移」的原因;進而研究了led光誘導血細胞產生熒光光譜的機理。
