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.
