sodium chloride structure 中文意思是什麼
sodium chloride structure
解釋
氯化鈉型結構-
When the two reactants were simply mixed by crush, they reacted violently and produced carbon spheres with a diameter of 50 - l00nm and sodium chloride ( nacl ) was encapsulated within the outer amorphous carbon shells, which could be confirmed by sem and tem. by annealing at 1400 ? to drive the encapsulated nacl away, hollow carbon spheres were left with a novel mesoporous structure, as presented in hrtem
實驗中將兩種反應物通過直接擠壓混合后加熱反應,得到的無定型球狀碳材料經tem照片證實直徑為50 - 100納米,而且中間包裹氯化鈉( nacl )顆粒; xrd等結果顯示,高溫退火併徹底清除nacl后形成的中空碳球已經部分石墨化。 -
Mix mineral additive into concrete has great effect on the pore structure, especially the addition of sodium sulfate coarsening the pore structure enormously, and increase the total porosity. after mixing sodium sulfate, the chloride ion diffusion coefficient of air entraining concrete increased, impermeability reduced ; but mixing sodium nitrite and sodium chloride can
Na _ 2so _ 4摻入后,引氣混凝土的氯離子擴散系數增大,抗滲性降低;而nano _ 2和nacl能夠細化水泥石的孔結構,對混凝土的抗滲性有利,但提高幅度不大。
