sedimentation-equivalent particle

Compared with the normal tidal flat sedimentation, the storm sedimentation has the characteristics of coarse particle, bad sorting, relatively high roundness, obviously graded bedding, typical parallel bedding, cross bedding.

该带的风暴沉积与正常的潮滩沉积比较，具有粒度较粗，分选较差，磨圆稍好，递变现象明显，平行层理或波状交错层理发育比较典型的特征。

Based on the Stokes formula and Lambert-Beer Law, a series of recurrence formulae were advanced to calculate particle size distribution from the data obtained by disc centrifuge photosedimentation, with the effect of extinction efficiency of particles and the radial dilution during sedimentation considered.

针对光透过离心沉降法的数据处理，综合应用Stokes公式和Lambert-Beer定律，考虑了颗粒消光系数的影响和离心沉降中的径向稀释效应，提出计算颗粒粒度分布的递推算法。

The electrochemical performances of graphite anode for Li-ion batteries were studied in this paper. Graphite samples with different particle size distributing were gained by sedimentation technology; some natural flake graphite were oxidized in air, and some were doped with metal oxidation such as Li2O and NiO.

本文利用沉降技术制备了不同粒度分布的石墨，通过不同温度的氧化处理、掺入Li2O和NiO等工艺制备了改性的天然鳞片石墨；

Then compared the sedimentation time, particle size and zeta potential with the before modified one.

然后比较表面改性前后的沉降时间, 粒度大小和ξ电位,并确定表面活性剂的用量.

The rate of sedimentation of a suspended viral particle depends on its size and density.

悬浮病毒粒子的沉降率因其大小和密度而异.
