cylindricity error is defined as the changes between measured column and ideal column.
圆柱度误差是指实际被测圆柱面对其理想圆柱的变动量。
The nodal temperature changing with time in H-shaped steel column is solved by using computer and draws the isothermal line in order to study the more ideal cooling means of H-shaped steel column.
