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。 -
The decrease of organic matter and the increase of alkali - hydrolyzable nitrogen of the hydrogen treatment were higher than the control, and urease activity, nitrogen fixation arnmonification had the same tendency, and amino acids had also changed. hi addition, comparing the control, ph of hydrogen treatment was increase and eh was decrease, and microbe mass was also too
與對照相比，氫處理培養有機質減少量小、堿解氮的增量高，脲酶活性、固氮能力、氨化作用都較強，並且不同種類的氨基酸也表現出各自相應的差異來。此外，土壤經氫處理后，土壤的ph上升， eh下降，土壤微生物生物量也呈減少趨勢。 -
Compared to bare steel strand, galvanized steel strand ’ s anti - corrosion is worse in 3 % nacl solution. 3. the result of corrosion research in different ph value simulation acid rain show that bare steel strand has a low corrosion rate at ph = 4, corrosion rate at ph = 2 and ph = 6 is larger ; epoxy coating steel strand ’ s corrosion current intensity decrease with ph value ’ s minish ; reverse to epoxy coating steel strand, galvanized steel
3 、模擬酸雨中腐蝕研究結果表明，在不同ph值的模擬酸雨中，全裸鋼絞在ph = 4時腐蝕最慢， ph = 2時腐蝕最快， ph = 6時腐蝕速度居中;環氧鋼絞線腐蝕電流密度隨ph值的減小而減小;鍍鋅鋼絞與環氧鋼絞線剛好相反，腐蝕電流密度隨ph值的減小而增加， ph值越小，腐蝕電流密度越大，越容易遭受腐蝕。 -
It was found that before the plating, there is section time to gestating, that we call the " gestating time " and the plating was ended spontaneously after some time, named " plating time ". the analysis of the solution after plating indicated that the too much decrease of ph value results in the reaction to be stopped. the plating time was shortened when the ph and the temperature of the bath were increased
結果表明，鍍液ph浙江大學碩士學位論文范啟義2003年3月摘要值、施鍍溫度提高，由於反應的速度加快，使反應時間縮短；硫酸銅濃度提高，有助於加快反應速度，從而縮短反應時間； edta濃度提高，使鍍液穩定性升高，對反應時間的影響等效于硫酸銅濃度的降低；而甲醛濃度提高，雖然反應的速度加快，但由於可用於還原的量增加，因此反應時間增加；裝載量提高，因能鍍覆的表面積增加，使反應時間縮短。 -
