It points out: a rational arrangement of supplementary cathode can greatly uniformize the handsaw temperature duo to its double actions of redistributing heat source and reducing thermal radiation; less shield layers at the top of the furnace leads to more uniform horizontal temperature distribution. The horizontal plate between two rows of handsaws can enhance the radiative heat transfer at the center place, and therefore can reduce the temperature difference along both horizontal and vertical directions.
指出:辅助阴极具有重新分配炉内的热源分布和隔热保温的双重作用,合理添加辅助阴极对改善料筐内温度场的均匀性具有重要的作用;在渗金属炉的顶部减少辐射屏层数,可以在保证竖直方向满足工艺要求的同时改善水平方向的温度场的均匀性;料筐的几何结构对温度场有重要影响,锯条背之间的距离以60毫米为好;减少料筐材料的发射率有利于局部控制料筐温度。

The proposed algorithm can preserve invariability on the geometric structure: the eigenvectors which are neighboring each other in the original space will maintain the same attribute in low-dimensional space; on the contrary, the unsimilar eigenvectors become apart farther each other. Therefore, the description generated by our algorithm can show the interrelationship between features and has strong robustness.
所提出的算法能保持描述器之间的几何结构不变:原空间中邻接的描述器映射到低维空间后保持邻接,而不相似的描述器映射后区分度更大,所以该算法所生成的描述器能表现特征点之间的内在关系,具有很强的鲁棒性。
