根据Archimedes原理设计了测量熔体密度的新型沉锤和测量程序并导出了新的计算密度的公式,建立了联称法。此法在同样实验条件下较修正法和二球法都更准确。
According to the principle of Archimedes, a new type of sinker and measuring program for measuring melt density were designed and a new formula of calculating density was derived. This method is more accurate under the same experimental conditions than the two-ball method.
