使用收縮寬度法迂迴測量明渠水流流量的標準試驗方法And the value drop to the lowest at ph = 0. 8. as the increase of heat treatment temperature, the pore size distribution peak of sio2 microspheres is very narrow, meanwhile the specific surface area is the smallest before 160 c. the polymer template is removed at 350 c, so the pore structure of sio2 particles has a big change which involve the increase of specific surface area and the broaden of pore size distribution peak. with the continuous raise of temperature the sio2 network will shrink little, as a result the average pore size will decrease, but the specific surface area has no obvious change
結果發現：二氧化硅膠體顆粒均勻分佈於脲醛聚合物網路中，煅燒去除有機模板后微球表面變粗糙，而粒徑沒有明顯變化； ph值較小時，復合微球中聚合物含量較大，而ph值較大時，得到復合微球結構鬆散，因此熱處理后的二氧化硅微球孔容及平均孔徑都較大，而在ph = 0 . 8時，得到最小值；武漢理工大學碩士學位論文隨著熱處理溫度的變化，小於160時，空分佈較窄，而比表面積較小，在350時，由於有機模板的去除，微球孔結構發生突變，比表面積明顯增大，而孔徑分佈變寬，溫度繼續升高時，二氧化硅網路發生收縮，平均孔徑變小而比表面積由於有機炭化物的完全去除沒有太大變化;微球中的微孔在熱處理過程中處于平衡狀態，分佈沒有太大變化。For the first current plateau ， two kinds of sequential resonant tunneling of - process and - x process are observed in the wide barrier gaas / alas superlattice under various pressures for p < 2kbar ， the high field domain is formed by - process ， while for p > 2kbar ， the high field domain is formed by - x process when the barrier width was decreased to 2nm, we found that ground - state -
