【摘要】 采用微积分方法。推导出连续冷却过程中热模拟试样的膨胀曲线与相变动力学曲线之间的数学关系,即"杠杆定则";分析并讨论"杠杆定则"的适用范围,及因各相线膨胀系数不同,采用"杠杆定则"对体积分数进行计算的误差。更多还原

【Abstract】 The mathematic relation between dilatometric curve of the thermal simulation sample and transition dynamics curve during continuous cooling,named the lever rule,was deduced by using the method of differential and integral calculus.The applicability of the lever rule,with the calculation error of the volume fraction according to the lever rule introduced by the different linear expansibilities of the different phases,were analyzed and discussed.更多还原
