中文拼音 [bōlíhuàshīdù]
玻璃化濕度
英文
glass transition temperature-
Because it well reserves the chemical stability of inorganic glass, it has the following features : low density, low thermal conductivity, vapor impermeability, no water absorption, incombustibility, protection from mould and rat eating, high mechanical strength but easy to cut and able to bear all kinds of chemical erosions except the hydrofluoric acid
由於它完全保留了無機玻璃的化學穩定性，具有容重低導熱系數小不透濕不吸水不燃燒不霉變不受鼠嚙機械強度高卻又易加工，能耐除氟化氫以外所有的化學侵蝕。It is found that the chemical durability of na2o4teo2 glass is dominated by the humidity of the surrounding air during the processes of glass melting and the following cooling. the mystery that na2o4teo2 glass crystallizes after drop shaft experiment, which has puzzled glass researchers for many years, is solved. this work indicates a way for making na2o4teo2 glass with good chemical durability
此反應主要受玻璃在熔化和冷卻過程中的環境濕度控制，存放過程中的空氣濕度對它也有影響，這解決了困惑人們多年的落塔實驗中na _ 2o ? 4teo _ 2玻璃析晶的問題和na _ 2o ? 4teo _ 2玻璃穩定性難以控制的問題，為制備空氣中穩定的na _ 2o ? 4teo _ 2玻璃提供了明確的依據。This paper has analyzed water activity of food and close relation with moisture content, temperature, vitrification transfer temperature, provided measure methods based on different principles, listed some measure apparatus in common use, appointed to the problem existing in measure methods and apparatus in use
