As for pure aluminum foam, there is neglected effect of cell size on the strength and plasticmodulus.
对于泡沫纯铝，孔径对屈服强度及塑性硬化模量基本没有影响。

Cell-size has a significant effect not only on the crushing stress and plasticmodulus of aluminum foam, but also on the strain-rate sensitivity of material of this kind.
泡孔尺寸不仅影响着材料的屈服强度和塑性模量等，还影响着材料的应变率敏感性。

Plastic Optical Fibers (POF) have the advantages of low modulus, large diameter and flexibility etc. They have been widely used in our today's information society.
