Abstract: An $ n$-normal lattice is a distributive lattice with 0 such that each prime ideal contains at most $ n$ minimal prime ideals. A relatively $ n$-normal lattice is a distributive lattice such that each bounded closed interval is an $ n$-normal lattice.

The main results of this paper are:

(1) a distributive lattice $ L$ with 0 is $ n$-normal if and only if for any $ {x_0},{x_1}, \cdots ,{x_n}\varepsilon L$ such that $ {x_i} \wedge {x_j} = 0$ for any $ i \ne j,i,j = 0, \cdots ,n,{({x_0}]^ \ast } \vee {({x_1}]^ \ast } \vee \cdots \vee {({x_n}]^ \ast } = L$,

(2) a distributive lattice $ L$ is relatively $ n$-normal if and only if for any $ n + 1$ incomparable prime ideals $ {P_0},{P_1}, \ldots ,{P_n},{P_0} \vee {P_1} \vee \ldots \vee {P_n} = L$.
