In the hot repressing of the powder sintered preforms, the increasing forging force increases its densities at a constant temperature.
在相同温度下进行粉末烧结体热复压,锻造力的增加往往使锻造密度也增加。

The results showed that a multitude of small sparks covered the entire surfaces of the samples at applied constant current densities.
结果表明:不同电流密度时,都可在阳极表面观察到细小电火花。

The densities of the phonon states have been calculated and compared with those in the case of the homogeneous alloys and in the case without considering the force-constant disorder.
