： The strength and the permeability of the cigarette paper depends largely on the quality of the Precipitated calcium carbonatePCC especially on the crystal type the size and the size distribution of the PCC particles．The settling volume represents to a great extent though not strictly the characteristics of the particle size and the size distribution of the PCC

卷烟纸用沉淀碳酸钙（PCC）的品种特别是晶型、粒度与粒度分布对卷烟纸的强度、透气度有较大的影响；沉降体积指标反映了PCC粒度的大小趋势，但该指标数据显示与实际情况有差距。

Differences in the particle morphology of calcium carbonate produced by different enterprises were compared through SEM,and the differenccs were characterized by settling volume and oil absorption.

通过SEM比较了不同厂家的碳酸钙颗粒形态的差异,并通过沉降体积和吸油量来表征其差异,进一步分析了轻质碳酸钙沉降体积对PVC试样力学性能的影响。

Then the modifier amount can be regarded as the best dosage that is confirmed by settling volume in liquid paraffin and the modified mechanism is given in the end of the paper.

然后通过在液体石蜡中的沉降体积验证了此改性剂用量可以作为最佳剂量,最后给出了偶联剂的改性机理。

5%,25% and 50%,the cumulative settlements of the model piles are studied in saturated sand,and it is investigated that how the dynamic displacements change with cyclic numbers.

5%,25%,50%三种情况下的沉降试验,研究了模型桩在不同动力循环加载情况下的桩顶累积沉降和动位移幅值随振动次数的变化而改变的规律,拟合了沉降试验曲线的回归方程。

Based on the undrained cumulative deformation model and the cumulative pore pressure model of the soft clay presented by Huang and employing the static and dynamic finite difference method,the cumulative settlement of Shanghai soft clay subgrade was computed and analyzed.

基于黄茂松提出的上海软粘土不排水累积变形模型和累积孔压模型,借助静态和动态有限差分法,对上海软粘土地基的累积沉降进行了计算分析。
