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
採用發射光譜儀對進口低溫透明釉進行半定量分析，並用原子吸收光譜儀測定其陶瓷製品的鉛、鎘的溶出量，分析化學成分對鉛、鎘溶出量的影響.結果表明，進口低溫透明釉採用低鉛配方不能解決鉛溶出量的超標問題，只有採用無鉛釉才能解決.探討用氧化鋰和氧化鍶等新型熔劑完全代替氧化鉛的工藝，研究釉料中氧化硅、氧化鋁、氧化硼和各種金屬氧化物的含量，對釉的線膨脹系數、熔融溫度和透明度等性能的影響.分析坯料、釉料的線膨脹系數及其相互關系和釉料制備的工藝，研製出優質的1000 1050低溫無鉛透明釉 -

Telephone communication is the most widely employed ways of communication in the world. telephone communication is becoming more and more important as the national economic reform deepens. dynamic channel borrowing assignment mode is an effective method in communication channel expansion. although it has been put into practical use in satellite communication and mobile communication, no one has attempted to apply it to telephone line expansion. in this paper the author expands the telephone line via dynamic channel borrowing assignment mode, ascertains the expansion scheme, designs the circuit of hardware in telephone line expansion device, draws up software programme, analyses the call lose after using the expansion device theoretically and then experiments to verify it. eight subscribers can share one or two telephone lines with the help of the telephone line expansion device with each phone a sole number. this makes it possible for subscribers to use any free telephone line. thus increasing the number of subscriber and utilization ration of telephone line. in addition. this project makes it possible for expansion subscribers to communicate directly while not to make use of outer line. which further decreased the system call lose
多通道共用是通信通道擴容的一種有效的方法，已在衛星通信、移動通信中得到應用，但尚未應用到電話線路擴容中。本文利用多通道共用原理對電話線路進行擴容，確定了多通道共用方式電話線路擴容的設計研究方案，研究設計了電話線路擴容器的硬體電路，編制了電話線路擴容器的軟體，並對使用電話線路擴容器后的呼損進行了理論分析及試驗研究。本文研究設計的多通道共用方式電話線路擴容器可以使8個用戶共用1 2對電話線路，每部用戶話機都具有獨立的電話號碼，可以利用任一空閑的電話線路，故能夠增加電話用戶，提高電話線路的利用率。 -
