(1)OBJECTIVE Estimation of the removal force of model particulate soil in liquid media by ultra-centrifuge and laminar flow has to be persued.(2)APPROACH AND MAIN RESULTSA. Approach:Glass and polystyrene particles adhered to a glass plate and polyester, acetate, cellulose films were set in ultra-centrifuge equipped with an angle rotor of which the angle being changed from 15゜to 45゜, and then were removed in various experimental conditions; i.d. washing time, rpm of the centrifuge, and particle size. Laminar flow was also used.B. Analysis of the Results:Correlation between the removal force Fc(horisonal component Fh and vertical component Fv) vs. particle size has been observed. 1) The removal percentage increased with increasing washing time, and particle size, and were proportional to rpm of centrifuge. 2) The ratio of Fh and Fv were adjusted by changing rotor angle at constant Fc. The removal percentage increased with increasing Fh (i.d. decreasing angle rotor). 3) Comparison of removal percentage given at the same removal force of both methods (cnetrifuge, laminar flow) were shown Table 1.

（1）对超离心和层流条件下液体介质中模型颗粒土的去除力进行客观估算。（2）进近和主航道。方法：将粘附在玻璃板上的玻璃和聚苯乙烯颗粒以及聚酯、醋酸酯、纤维素薄膜置于装有角度从15 °到45 °变化的角度转子的超离心机中，然后在各种实验条件下除去; i.d.洗涤时间、离心机的rpm和粒度。也使用层流。结果分析：已经观察到去除力Fc（水平分量Fh和垂直分量Fv）与粒度之间的相关性。1)去除率随着洗涤时间的增加而增加，并且与离心机的转速成正比。2)通过在恒定Fc下改变转子角度来调节Fh和Fv的比率。去除率随着Fh（i.d.）的增加而增加。减小角度转子）。3)两种方法（离心法、层流法）在相同去除力下给出的去除百分比比较见表1。
