The rates of 14 N/ 12 /C in wheat seeds wene measured by using 14 N( d,p ) 15 N and 12 C( d,p) 13 C reactions induced by 13.4MeV deuterons which wene produced by a cylotron.According to the measured 14 N/ 12 C rates,t...The rates of 14 N/ 12 /C in wheat seeds wene measured by using 14 N( d,p ) 15 N and 12 C( d,p) 13 C reactions induced by 13.4MeV deuterons which wene produced by a cylotron.According to the measured 14 N/ 12 C rates,the relative protein contents in different wheat sorts were defermined and compared with the results obtained by the Kjeldahl method.展开更多
Given a list assignment of L to graph G,assign a list L(υ)of colors to each υ∈V(G).An(L,d)^(*)-coloring is a mapping π that assigns a color π(υ)∈L(υ)to each vertex υ∈V(G)such that at most d neighbors of υ r...Given a list assignment of L to graph G,assign a list L(υ)of colors to each υ∈V(G).An(L,d)^(*)-coloring is a mapping π that assigns a color π(υ)∈L(υ)to each vertex υ∈V(G)such that at most d neighbors of υ receive the color υ.If there exists an(L,d)^(*)-coloring for every list assignment L with|L(υ)|≥k for all υ∈ V(G),then G is called to be(k,d)^(*)-choosable.In this paper,we prove every planar graph G without adjacent k-cycles is(3,1)^(*)-choosable,where k ∈{3,4,5}.展开更多
