变均匀

A study of phase morphology of PBT/POE-g-MAH/nano-CaCO3 composite by means of scanning electron microscopy showed that the domains size of nano-CaCO3 capsulated by POE-g-MAH elastomer in composite when PBT was mixed directly with POE-g-MAH and nano-CaCO3 together or with nano-CaCO3 capsulated by POE-g-MAH elastomer is large.

采用熔体流动速率较低的EPS30R与纯POE-g-MAH共混制备的增韧改性剂，在PBT基体中的分散相变得粗大且不均匀，共混物的脆韧转变推迟。SEM显示，纯POE-g-MAH增韧剂使PBT共混物发生脆韧转变时，弹性体分散相颗粒产生塑性变形，诱发基体屈服而吸收能量。

The fundamental imaging features of osteosarcoma were showed bone destruction, periosteal reaction, neoplastic bone and soft-tissue mass. Among 49 cases examined by radiography, osteoblastic pattern sarcoma was found in 19 cases, osteolytic pattern sarcoma was found in 13 cases and mixed pattern sarcoma was found in 17 cases. The detection rates of bone destruction, periosteal reaction, soft-tissue mass, neoplastic bone and Codman triangle by radiography were respectively 61.2%, 95.9%, 71.4%, 73.5%and 27.7%. All 10 cases with CT scan were showed bone destruction, soft - tissue mass and neoplastic bone. The detection rates of periosteal reaction,憇ieve sign挶 and Codman triangle with CT scan were respectively 90%, 90% and 11%. The tiny neoplastic bone and"sieve sign"were showed sensitively by CT, but Codman triangle was showed by radiography superior to CT.32 cases with MRI scan presented the normal marrow was replaced by the tumor, which was showed low to intermediate signal intensity on T1-weighted images and promiscuity signal intensity on T2-weighted images. 7 cases presented hemorrhage and 24 cases presented necrosis.
