Increasing the calcining temperature at 1500℃ 5h, the morphologies of the product became the big and wide vermiform-fiber form particles, the length was about 2.5 μm, and the width was about 700 nm. In addition, the vermiform-fiber form particle could be found in the filtrated precipitate with the additional ammonium sulfate. If the ratio of ammonium sulfate to alum is above 1, the vermiform-fiber form particle was formed. After calcined at 1500℃ 5h, the particle grow up to 2μm. Adding ammonium sulfate was also reduced the particles size of alumina because the surface area of the products was increased by increasing the quantity of ammonium sulfate.

同时，通过CVB-PIV对单个或多个粒子的静止、直线运动、摆动和圆周运动的研究，以及对平面镜角速度等参数对于粒子影像的影响和粒子面外位置与粒子影像偏移量对应关系的探讨表明，静止粒子的影像是一个圆，圆心坐标与粒子的面内位置相对应，圆的半径就是粒子影像的偏移量，与粒子的面外位置一一对应。

The diameter of nano-particle is small and its surface energy is high. Atomic valence bond of particle surface is not saturation and surface atoms have extremely physical and chemical activity. So, nano-particle is apt to agglomerate to make difficult to bring its excellent properties to completely play and to modify polymer.

纳米粒子粒径小，表面能大，且粒子表面的原子价健处于不饱和状态，表面原子有极大的物理与化学活性，因此纳米粒子非常易于团聚和吸附，而使得其拥有的性能难以充分发挥，从而失去应有的对高分子材料的改性作用。

Surface tension of nanometer particle La(1-x)Sr_xMnO_3 can be reduced remarkably that adding un-ionic surface-active agent. It prevent colloidal particle from growing up and original particle reuniting, thereby minish effectively particle size of oxide and improve its dispersing.

添加非离子表面活性剂可以显著降低纳米微粒 La_(1-x)Sr_xMnO_3的表面张力，防止原生粒子团聚和胶体粒子长大，从而有效地提高粉体的分散度并减小粒径。

The wash-out of the particle slope, in practice is how the particle stone to move under the breaking wave"s force. The main elements deciding the force are the wave factor, the slope angle and the particle size. Through analyzing the particle"s suffering process during each stage of waves breaking, it can be advanced that the wave force is biggest just at the wave incidence to the slope.

波浪对散体边坡的冲刷，实际上是颗粒在波浪作用下的受力起动问题，力的大小主要由波要素、斜坡倾角和颗粒粒径决定，且通过对破波各阶段颗粒的受力分析，可知颗粒在破波瞬间受到的作用力最大。

The experimental results show that when TCAR is about 700 ℃ XN for limestone is maximum, and the optimum TCAR for dolomite is about 650℃. Although XN for limestone is much higher than dolomite, the difference of their YN is little when TCAR is in 650~700 ℃. And if TCAL is beyond 1050 ℃ XN for limestone decays sharply, but it is negligible to dolomite. XN for dolomite is far higher than limestone in the high TCAL. XN for limestone decreases with the particle size increasing, and there is an optimum particle size range with particle size increasing which XN for dolomite reaches maximum in. The particle size plays a more important role in limestone carbonation process than dolomite.

结果表明：TCAR为700℃时石灰石的XN最高，白云石则在650℃时XN最高，在650～700℃时白云石的XN远高于石灰石，但它们的YN相差不大；当TCAL超过1050℃时石灰石的XN急剧衰减，而白云石的XN则衰减程度不大，在高温煅烧时白云石的YN比石灰石更高；随粒径的增大，石灰石的XN逐渐减小，而白云石则存在最佳的粒径分布使XN最大，粒径的变化对石灰石的XN影响更大。
