( 3 ) we bring bdf method of order two forward as time discrete method for the two - dimension three - temperature heat conduction equations ( 3 )提出使用二阶bdf方法作为二维三温热传导方程的时间离散化方法。
2.
Theoretical analysis and numer - ical experiments show that bdf method of order two is indeed superior to the commonly used backward euler method and crank - nicolson scheme 理论分析和数值试验表明该方法明显优于以往常用的向后euler法及grank - nicolson格式。
