When the sodium lauryl sulfate and p-octyl polyethylene glycol phenyl ether is used and its level in 3% and 6: 4 ratio, the polymerization process has the lowest coagulum and the highest monomer conversion. Higher reaction temperature and more level hydroxyl value lead to more coagulum, the latter also lead to larger particle size. The acid value has larger influence on viscosity and coagulum, there exist a best range. The emulsion particle size is larger for its hydrophilicity, most of its particles are connected together.

在含较高亲水单体的乳液聚合体系中，难以制得稳定的预乳化液，不能采用工业生产中常用的预乳化工艺，而只能采用混合单体直接滴加的方法；由于单体混合物的亲水亲油值较高，用阴离子型乳化剂十二烷基硫酸钠和非离子型乳化剂聚乙二醇辛基苯基醚混合，用量为单体总量的3％，且比例在6：4时，乳液聚合时具有最低的凝聚物含量和最高的单体转化率；乳液聚合反应温度升高，可以提高单体转化率，增加反应速度，但凝聚率相应提高；随着羟基单体含量的增加，聚合过程中凝聚率增加，聚合物乳胶粒平均直径增加；羧基单体有一个最佳的用量（2.6％），过高或过低凝聚率均提高；羧基含量对乳液的粘度有较大的影响，当羧基含量较低时，羧基含量增加，乳液粘度增加明显；含羟基乳液粒子由于含亲水基团较多，使得乳胶粒径增大，乳胶粒子大多数互相凝聚在一起，处于凝聚态。

After 25% deformation at 850℃, and relaxation for 6 to 30 seconds, a great deal of fine Nb particles precipitates in steels, the size of particles is less than 10nm. With the increase of relaxation time, the amount of precipitates starts to decreases, the size coarsen to greater than 10nm.

在850℃变形后随驰豫时间的延长，在6～30秒内有大量细小的Nb粒子应变诱导析出，其尺寸小于10nm，驰豫时间再进一步延长，析出数量开始减少，粒子的尺寸粗化为10nm以上。

Another important result is that, which can be easily drown from the figure of probabilities of the states vs pump power with different x, or the common logarithm figure of the populate probabilities vs x , the increasing of the concentration of Er ions increase both energy transfer which populate the state and the cross relaxation process which depopulate the state, but the total result is that ion number of high lying states increase with concentration.

从不同掺杂浓度下各态布居几率或粒子数与光强的变化关系图可以看出，虽然掺杂离子浓度的增大同时增强了产生上转换荧光能态布居的能量迁移上转换过程和消耗该能态布居的交叉驰豫过程，但两者竞争的结果是较高的掺杂浓度对产生高能激发态的粒子数有利。

But for the strong activity of Nano-TiO2, the conglobation will happen easily, and it will greatly reduce the application effect in coating. And for the hydrophilicity , its hard to break up uniform in resins, so air gaps appear in the interface, then the high polymer in the interface willhappen degradation reaction or embrittlement reaction, and coatingsperformance will fall down.

但是由于纳米粒子表面极强的活性，使它们很容易团聚在一起从而形成带有若干弱连接界面的尺寸较大的团聚体，这大大降低甚至消除了纳米颗粒的实际应用效果，同时由于纳米粒子表面亲水疏油，在有机高分子树脂中难于均匀分散，界面上会出现空隙，当空气中的水分进入空隙中就会触发界面处高聚物的降解、脆化，导致涂层失效。
