Because the bottom of the plate temperature distribution is uniform,so will only produce temperature difference in the vertical direction,will not make cake edge uneven temperature distribution,so ignore this problem.Another is the edge of the plate wall on the cake of heat conduction,the heat around the high,so it is the main cause of uneven temperature distribution in the edge of cake.So the problem is reduced to a rim around the cake and the heat conduction problem.
英语翻译因为盘底温度分布均匀,所以只会在垂直方向产生温度差异,不会使得蛋糕边缘温度分布不均,所以忽略此问题.另一个是盘子
