空洞化
1.
AIM particles distribution and its cavitations in PVC resin, the fracture and brittle-ductile transition of AIM/PVC blends were investigated.
研究了增韧剂粒子在PVC中的分散和空洞化、AIM/PVC共混物的断裂与脆韧转变。
2.
The results show that the stress-whitened area isformed near the fracture surface,where seriously cavitations are formed in ACRparticles.
结果表明,以韧性方式断裂的共混物会产生明显的应力白化区,且区内ACR粒子呈现出严重的空洞化形变,因此空洞化诱导聚氯乙烯塑料基体发生剪切屈服是ACR增韧聚氯乙烯的机理。

补充资料：空洞
空洞
脏器内发生坏死或液化的物质排出后，在病变部位留下的洞腔、坏死和液化。常由炎症引起，常见的如肺、肾等内脏的结核性空洞。在适当的情况下，空洞可通过再生而修复。
