Its rule of change was obtained. On the basis of other studies, the flocculation kinetics and flocs structure was studied. By making some assumptions, collision frequency were presented. Then the the flocculation kinetics model was established through population balance equation. Comparison of experimental data and modeling results indicate that there are the same trend between the two. So the model can predict flocs number and size during flocculation of Yellow River's loess particles without using empirical parameters. The TEM and SEM were used to obsever flocs in the study of floc structure. The flocculation was divided as flocculi, floc and floc aggregate. The flocs structure model was established by assumption that particles position in floc accords with tetrahedron. The fractal dimension of model and experimental flocs was found to be coincident. So the model can reflect the structure of flocs formed in flocculation of Yellow River's loess particles by macromolecule flocculant at a certain extent.

最后，本文还对絮凝动力学和絮体结构进行了研究，在前人研究的基础上，针对高分子絮凝黄河泥沙，对絮凝过程作了一些符合试验条件的假设，建立了颗粒碰撞频率表达式，应用了颗粒数量平衡方程，从而建立了絮凝过程的动力学生长模型，模型计算结果与试验数据对比表明，二者趋势一致，在没有使用经验参数的情况下基本上能够描述黄河泥沙絮凝过程中絮体数量和尺寸分布的变化过程；对絮体结构的研究中，应用扫描电子显微镜和透射电子显微镜对絮体进行了观察，将絮体分为絮粒、絮团和絮网三个不同的生长阶段，通过假设颗粒结合位置符合正四面体，建立了絮体结构模型，计算得到的模型絮体分形维数基本与试验中的实际絮体相符，在一定程度上能眵反映高分子絮凝黄河泥沙生成的絮体结构。

On bright, calm days they lie in thousands on the now darkening water, mostly yellow flotillas of poplar, floating continuously down from great trees that themselves shake in the windless air with the sound of falling water , but on rainy days or after rain they seem to swim or be driven away, and nothing remains to break the surface except the last of the olive-yellow lily pads that in high summer covered every inch of water like plates of emerald porcelain...

当风和日丽时，无数的树叶浮在已经变暗的湖水上，大部份都是白桦叶子，他们一批一批，像黄色的小小扁舟，不断地从高高的树上飘落下来，在无风的空气中轻轻地晃动着，发出如同流水而下的声音。但是在下雨的时候，或者雨过之后，那些浮在湖面上的落叶，仿佛鱼儿一样都游走了，又像是被不知什么驱赶一空，湖面上除了最后的几片黄绿色睡莲叶子，再无一物，而在盛夏里，那些睡莲叶子，如同翠绿晶莹的瓷盘，覆盖着每一寸湖面。

On bright calm days they lie in thousands on the now darkening water mostly yellow flotillas of poplar floating continuously down from great trees that themselves shake in the windless air with the sound of falling water but on rainy days or after rain they seem to swim or be driven away and nothing remains to break the surface except the last of the olive- yellow lily pads that in high summer covered every inch of water like plates of emerald porcelain.

在风和日丽的日子里，白杨树叶伴着水流的节奏簌簌地落下，像一叶叶黄色的扁舟，成千上万地泊在这秋水中。在下育的日子里或育后时节，它们或游离此地，或随波逐流。平静的湖面上只剩下残存的黄绿色的睡莲叶子。而盛夏时，睡莲叶子宛如葱绿晶莹的瓷盘，覆盖着湖面的每寸水域。睡莲凋零了。

On bright, calm days they lie in thousands on the now darkening water, mostly yellow flotillas of popular, floating continuously down from great trees that themselves shake in the windless air with the sound of falling water ,but on rainy days or after rain they seem to swim or be driven away ,and nothing remains to break the surface except the last of the olive –yellow lily pads that in high summer covered every inch of water like plates of emerald porcelain.

这些数叶大多是杨树叶，如一列列黄色小艇般不停地从那些无风也簌簌的高大树木上落下来，落雨般淅淅沥沥。但是在雨天或雨后，它们却飘得无影无踪，或像被什么赶走了，此时湖上只剩下橄榄黄色的睡莲碎片，在盛夏时，碧绿的莲叶曾像盏盏翡翠玉盘一样把整个湖面盖得密不透风。

On bright ,calm days they lie in thousands on the now darkening water,mostly yellow flotillas of popular,floating continuously down from great trees that themselves shake in the windless air with the sound of falling water,but on rainly days or after rain they seem to swim or be driven away,and nothing remains to break the surface except the last of olive-yellow lily pads that in high summer covered every inch of water like plates of emerald porcelain .

在晴朗无风的日子里，树叶成千上万聚集在颜色转暗的湖面上，这黄色的如同小舟一般的落叶--大多数是白杨树叶---纷纷从那些即始无风也抖动不已的高树上飘落下来，淅淅沥沥，仿佛水声，但是遇上雨天，它门又漂得无影无踪，于是，除了那在盛夏时节宛如盏盏翠莲把湖面覆盖而如今只是一片橄榄黄的睡莲残叶

However, there are always some time, stretch a bit sad brow sky, the sun would drop by drop down the drain, as if heaven and earth step by step, little by little to be painted yellow, like a painted warm colors of the bakery, with wooden shelves, braved a plume of mist of hot coffee, warm yellow light, strong enough to touch the egg tart flavor, may be fresh-baked cheese cake, but I fear, are the flavor of the sun.

但总有一些时候，忧愁的天空舒展了一下眉头，阳光便一滴一滴的漏了下来，天地好像一层一层，一点一点地被漆成了淡黄色，像是涂着暖色调的面包房，有着木质的架子，冒着一缕缕雾气的热咖啡，温馨的淡黄色灯光，浓郁到可以触碰到的蛋挞的香味，或许是刚出炉的芝士蛋糕，但总归是阳光的味道。
