Using B Grade bauxite as bone material and A Grade bauxite as powder,different binder composition castable for permanent lining fo fundish were studied,with cyanite and sillimanite as expansion additives and Zimujie clay as sinter additive and plastic additive.

以B级高铝矾土熟料为骨料，A级矾土熟料为基质料，同时加入蓝晶石、硅线石为膨胀剂，紫木节粘土为烧结剂、塑化剂，研究了分别采用硅灰、高铝水泥、水玻璃、复合结合剂等为结合剂的不同配方组成的浇注料。

Earthworks zero line is determined by constructing the spatial gridding curved surface model of the original terrain and the field leveling design terrain by digital elevation mode. The DEM data of original terrain are obtained by actual measurement. The mathematical correlation is deducted to demonstrate the relationship between the coordinates of any point on spatial line and the direction cosine by the spatial linear equation. DEM data obtaining program is compiled by Fortran9.0 and it is applied automatically to obtain the DEM data of field leveling design terrain.
