碳化硼的独特性能包括:高硬度,化学惰性和高吸收中子,横截面。
玻璃在日常环境中呈化学惰性,亦不会与生物起作用,故此用途非常广泛。
由于氮极大的惰性,不能与氧结合,所以这个问题被渲染得过分困难。
(126)的空间效应也是它对格氏试剂反应迟钝的原因
1·So platina is like a diminutive of silver, but we now know that platinum is far superior to silver It is far more noble. It has a higher melting point, a higher chemical inertness, a fantastic metal.
所以普拉塔就像一个小小的银,但我们现在知道普拉塔比银要好很多,更为珍贵,熔点更高,化学惰性更高,是一种非常不可思议的金属。
2·These are the metals of COINS and jewelry, not only because of their comparative rarity and beauty but also because of this chemical inertness.
这些金属是制造硬币和珠宝的金属,不只是因为它们的相对稀缺和漂亮,而且还因为化学惰性。
3·The improvement field emission by Hf coating on CNTs surface is attributed to the low work function, chemical inertness and good conductivity of HfC.
我们认为碳纳米管表面发射性能的提高归功于表面碳化铪膜良好的导电性、化学惰性和低逸出功。
4·The improvement field emission by hf coating on CNTS surface is attributed to the low work function chemical inertness and good conductivity of HFC.
我们认为碳纳米管表面发射性能的提高归功于表面碳化铪膜良好的导电性、学惰性和低逸出功。
5·Engineering ceramic materials have attractive properties: high hardness, high thermal resistance, chemical inertness, low thermal conductivity and low fracture toughness etc.
工程陶瓷材料具有引人注目的特性:高硬度、高耐热性、化学惰性、热传导率低、断裂韧度低等。
