例句与用法

1. 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
   结果发现：二氧化硅胶体颗粒均匀分布于脲醛聚合物网络中，煅烧去除有机模板后微球表面变粗糙，而粒径没有明显变化； ph值较小时，复合微球中聚合物含量较大，而ph值较大时，得到复合微球结构松散，因此热处理后的二氧化硅微球孔容及平均孔径都较大，而在ph = 0 . 8时，得到最小值；武汉理工大学硕士学位论文随着热处理温度的变化，小于160时，空分布较窄，而比表面积较小，在350时，由于有机模板的去除，微球孔结构发生突变，比表面积明显增大，而孔径分布变宽，温度继续升高时，二氧化硅网络发生收缩，平均孔径变小而比表面积由于有机炭化物的完全去除没有太大变化;微球中的微孔在热处理过程中处于平衡状态，分布没有太大变化。
