对Nerd们的注解：可能是个格，顶尖；形状不重要，这里至少有个偏序关系。

Note to nerds: or possibly a lattice, narrowing toward the top; it's not the shape that matters here but the idea that there is at least a partial order.

在计算属性约简集的基础上，建立了雷达干扰空间的偏序关系矩阵。

Based on the reduction of attribute sets, the partial order relation matrix of radar jamming space is obtained.

通过定义离散化方案之间的偏序关系以及交、并运算，将各种离散化方案组织成离散格。

All discretization schemes are organized into a lattice named discretization lattice after partial order relation, then the meet and join operations between discretization schemes are defined.
