Recorded icing data of power transmission line is rarely in China,so it is difficult to determine the design icing thickness,and is mainly obtained by sitting investigation and short-term icing observation.
2008年南方大冰灾中的实测资料为覆冰设计提供了直接依据,但若简单以本次冰灾的覆冰厚度折算成标准冰厚作为设计覆冰,而不考虑实际运行情况,往往会使设计覆冰取值偏于保守,造成资源浪费。
A G-design(G-packing design,G-covering design)ofλK_v,denoted by(v,G,λ)-GD((v,G,λ)- PD,(v,G,λ)-CD),is a pair(X,B)where X is the vertex set of K_v and B is a collection of subgraphs of K_v,called blocks,such that each block is isomorphic to G and any two distinct vertices in K_v are joined in exactly(at most,at least)λblocks of B.
λK_v为λ重v点完全图,G为有限简单图,λK_v的一个G-设计(G-填充设计,G-覆盖设计),记为(v,G,λ)-GD((v,G,λ)-PD,(v,G,λ)-CD),是指一个序偶(X,B),其中X为K_v的顶点集,B为K_v中同构于G的子图的集合,称为区组集,使得K_v中每条边恰好(至多,至少)出现在B的λ个区组中。
A graph design G-GDλ{v) ( graph packing design G-PDλ(v), graph covering design G-CDλ(v)) of XK_v is a pair (X, B) where X is the vertex set of K_v and B is a collection of subgraphs of K_v, called blocks, such that each block is isomophic to G and any two distinct vertices in K_v are joined exactly (at mos.
对于有限简单图G,图设计G-GD_λ(v)(图填充设计G-PD_λ(v),图覆盖设计G-CD_λ(v))是一个序偶(X,B),其中X是K_v的顶点集,B为K_v中同构于G的子图的族(称为区组族),使得K_v中每条边恰好(至多,至少)出现在B的λ个区组中。
