The influence of the chemical composition, particle form and annealing temperature of the amalgam alloy upon the creep of the resulting amalgam was investigated by means of a multiple regression model. Because no, or only little, information was available about the heat treatments of the different commercial alloys, the alloys were subjected to additional heat treatments at four different temperatures. The influence upon the creep of the amalgam of the Zn content, particle form and annealing temperature was found to be very significant. A higher Zn content as well as a spherical alloy resulted in less creep of the corresponding amalgam. The dependence of the creep upon the annealing temperature showed a minimum: more creep was obtained for amalgams prepared from the alloys heat treated at 150 degrees C and 435 degrees C than those from the alloys annealed at 315 degrees C and 319 degrees C, respectively.
采用多元回归模型研究了汞合金的化学成分、颗粒形态和退火温度对所得汞合金蠕变的影响。由于关于不同市售合金的热处理信息很少或几乎没有，因此对这些合金在四个不同温度下进行了额外的热处理。结果发现，锌含量、颗粒形态和退火温度对汞合金蠕变的影响非常显著。较高的锌含量以及球形合金会使相应汞合金的蠕变更小。蠕变对退火温度的依赖性呈现出一个最小值：由在150℃和435℃下热处理的合金制备的汞合金，其蠕变分别比由在315℃和319℃下退火的合金制备的汞合金更大。
