sodium tellurite 中文意思是什麼
-
The evaporation of sodium tellurite glass in low gravity is explored and the formation and growth processes of teo2 microspheres are explained. the size of teo2 microspheres from low gravity is much larger than that from ground experiments and it is affected mainly by the temperature of melt in the heating coil and the duration time of vapor cloud during drop experiments
探索了微重力對亞碲酸鈉玻璃熔體氣化的影響，分析了微重力下由於玻璃熔體氣化而生成teo _ 2玻璃微球的過程，解釋了微重力下形成的微球尺寸遠遠大於摘要地面模擬實驗所得微球的原因。 -
Sodium tellurite glasses are considered as potential candidates for non - linear optical applications because of high refractive index values and wide infrared transmittance. on the other hand, because the glasses have relatively low melting temperature and low viscosity after melting, they are often chosen to study the melting, evaporation and solidification of glasses in low gravity
另一方面，由於這類玻璃的熔融溫度較低，在溫度較高時會揮發產生氣體，熔融后熔體的粘度較低，玻璃形成能力強，因此被用來研究微重力下玻璃的熔化和氣化，和微重力對玻璃析晶能力的影響。 -
In the present dissertation, some properties of sodium tellurite glasses, including density, chemical durability, stability against crystallization and fragility of glass forming liquid are studied. the melting, evaporation and solidification of sodium tellurite glasses in low gravity during drop shaft experiments are observed. except this, the phase - separation of lead borate glasses under different gravity condition is also studied
本文亞碲酸鈉玻璃作為研究對象，系統探索了亞碲酸鈉玻璃的熔化條件，化學穩定性，玻璃抗析晶能力以及玻璃形成液體的脆性等問題，著重研究了na _ 2o - teo _ 2玻璃在落塔實驗中的熔化和氣化以及pbo - b _ 2o _ 3玻璃在落塔實驗中的分相，為解釋玻璃在不同重力條件下的熔化和分相等現象提供了理論依據。 -
Na2o - 8teo2 crystal is stable at temperatures below 330 and will decomposed into two crystalline phase including na2o4teo2 and teo2 at 340 or a higher temperature. the phase diagram of sodium tellurite is modified according to the results obtained. the transformation of na2o - 8teo2 into na2o4teo2 and teo2 includes two steps : na2o - 8teo2 is first transformed into an intermediate amorphous phase and then the intermediate amorphous phase crystallizes to form na2o - 4teo2 and teo2 - the intermediate amorphous phase formed during the transformation is amorphous powder
通過對nt _ 8晶相向nt _ 4和teo _ 2晶相的轉變過程的研究發現，由nt _ 8晶相向nt _ 4和teo _ 2晶相的轉變包括兩個轉變過程，即由nt _ 8晶相向非晶中間相轉變的過程和由非晶中間相向nt _ 4和teo _ 2晶相轉變的過程，在轉變過程中出現的非晶中間相是一種非晶固態粉末。
