随着温度的升高，磷酸料浆的黏度降低，料浆重力沉降速度增大，过滤时间缩短，但当温度升高到一定程度后，由于分子的布朗运动加剧，会使得重力沉降速度出现降低趋势，继而使其过滤时间变长。

In the process of electro-membrane filtration, the applied operation condition and membrane do not have significant electroosmosis effect through related experiment. Under the operation of 98KPa pressure, only 6% flux was increased, which showed the increase of flux in the applied electric field process mainly from electrophoresis effect. The effect of dye filtration by membrane is mostly influenced by the basic nature of dye, including size of molecular weight, electrophoresis motility and the adsorbability of dye to membrane.

在外加电场薄膜程序中，所用的操作条件以及所使用的薄膜，经电渗透实验显示电渗透的效应不明显，而在98KPa压力操作下，也仅增加6%的通量贡献，显示外加电场程序通量之提升主要来自电泳作用；薄膜过滤染料的效果主要受到染料基本性质的影响，包括分子量大小、电泳动能力与染料对薄膜的吸附能力。

Firstly, This paper processes geometry filtration based on character of orbit's apogee and perigee after orbit model is analyzed and based. Secondly Space Debris is separated into two kinds, coplanar and not coplanar according as location interrelation of target and debris. In Dynamic filtration's processing, considering prediction time limit and orbit perturbation, secular effects which have increaser effect is considered so that some need catching danger time point is appeased, some law about time when target and debris pass intersectant line each other is inferred, when debris and object are in different plane and some similar law also is inferred otherwise. The time list is arithmetical progression. These laws can improve calculation efficiency remarkably; Lastly orbit predict is a course approaching least distance. Danger time point in the last step become beginning time point from which debris and object's position and velocity are calculated by SXP4 Model which is an analytic model.By result, determine that relative movement trend is closer or apart, farther calculate the interval apart from time when predictive least relative distance occurs. Least relative distance and time when least distance occurs is calculated finally. It is a fast approach course adopting varied interval.

本文在分析、建立轨道摄动计算模型的基础上，首先采用基于轨道远、近地点特征对大量编目在册的空间碎片进行初步几何静态筛选，然后根据碎片与目标轨道面的相对位置特点把碎片分为异面与准共面两种情况以进行动态筛选，在筛选过程中考虑到预报时限长度和轨道摄动影响，引入了轨道摄动中具有积累效应的长期项以满足危险时间点的捕捉要求，利用了长期项摄动变化线性的特点导出了碎片与目标异面情况下各自过交线的时间序列成准等差数列的规律性和准共面情况下类似的规律性，从而显著地提高了前期轨道筛选的计算效率；最后对剩余危险碎片和目标飞行器利用SXP4轨道预报模型在前期轨道筛选的基础上以各个危险探测时间点为预报的时间起点，并根据预报计算结果，分析目标和碎片在该时间点的运动趋势是相互远离还是相互接近，推出预计最小相对距离发生时刻相对此刻的时间长度，得到其随时间变化的局部最小相对距离以及危险距离发生的时刻和相对速度，这是一个采用变时间步长、快速逼近最小相对距离的过程。
