密实，指茂密厚实；形容排列紧密。
n. thick
adj. dense
misc. closely knit
On the one hand guaranteeing reducing normal stress depression, enhancing the non-dense weld ability; On the other hand may cause the material to have the big plastic deformation, improving material tissues, obtaining the submicron even nanometer bulk materials.
一方面保证了法向应力的降低，提高非密实件的可焊性能；另一方面可以使材料产生较大的塑性变形，改善材料的内部组织，获得亚微米级甚至纳米级块体材料。
