本文介绍了直线拟合法计算晶格常数时,所用外推函数能否应用的判据,并通过误差分析确定计算精确度,以使适当选择计算方法和外推函数。
In this paper, the criterion of whether or not the extrapolated function can be used when calculating the lattice constant by the straight-line fitting method is introduced, and the calculation accuracy is determined by error analysis so that the calculation method and the extrapolation function are appropriately selected.
