The effects of many factors in the wet end on drainage and retention of PEO/attapulgite system: During the scope of 2-12, pH has no effect on drainage, and retention ratio lower in acidic conditions and higher in neutral or alkaline conditions. There were some improvement on slurry's drainage and some impairment on retention efficiency for the existence of inorganic salts. Lignosulphonate had no effect on drainage and made retention ratio decrease 5-8%; lignosulphonate and xylan had no effect on drainage and made retention ratio decrease a little. 5 .Attapulgite could be modified by intercalation.

纸机湿部系统的影响因素对PEO／凹凸棒粘土助留体系的助留助滤效果的影响表现为：pH值在2-12范围内，对助滤效果是没有影响的，使助留效果在酸性条件下较差，而在中碱性条件下较好；无机盐的存在使浆料的滤水性能有一定的改善，使助留效果有所削弱；木质素磺酸盐对助滤效果是没有影响的，使留着率下降了5—8％；木质素磺酸盐与聚木糖对助滤效果也是没有影响的，使留着率略有下降。

Work in this paper focuses on the data mining from chromatographic retention index data. A retention index database that contains about 50000 records of retention index is firstly established. Projection pursuit technique is then utilized to do data mining upon the data in order to find out some valuable information about the relationship between the retention indices and structural descriptors. A novel algorithm for projection pursuit is developed in this work. Samples of alkane, alkene and cycloalkane are investigated.
