求翻译：人们都取小尺寸的试样进行描述，用试样中颗粒形状来粗略的表征路堤颗粒形状 (忽略多尺度的效应问题) ，认为路堤颗粒与试样内的颗粒具有相似性。是什么意思？

People have taken the small size of the specimen to be described, a rough characterization of particle shape in the sample the embankment particle shape (ignoring the effects of multi-scale problems), that the particles in the the embankment particles and sample similarity.

It is the small size of the sample are described in a sample, the particle shape to the table, with a rough road embankments particles shape (ignore the effects of multiple scales) that embankment particles and the particles in a sample with the same.
