1) raceway control
套圈控制
1.
According to the dynamic static analytical method established by Jones raceway control theory,the contact and kinematic states between a ball and raceway are determined considering ball centrifugal forces and gyroscopic moments,and then the spin to roll ratio may be predicted.
根据Ｊｏｎｅｓ套圈控制理论建立的动静分析法，确定考虑球离心力和回转力矩，球和滚道之间的接触状态和运动状态，进而预测旋滚比。
2) dominating cycles
控制圈
1.
In simple finite graphs , we defined the concept of dominating cycles and proved that the length of dominating cycles in a kind of 2-connected graphs is 2σ-2,and this result improved the result of Tian Feng in some given conditions.
在有限无向简单图中,引进控制圈的定义,得到了一类2-连通图的控制圈的圈长至少为2σ-2,在一定的条件下改进了田丰等人证明的控制圈的圈长至少为2σ-3的结果。
4) dominating cycle
控制圈
1.
The author studies dominating cycle of directed graph with the method of studying dominating cycle of undirected graph, and proves that: Let D be a strongly connected simple graph of order n(n ≥7),for any arc( x,y ) of D ,if d -(x)+d +(y)>n -4,then D contains a dominating cycle.
采用有向图控制圈的研究方法对有向图控制圈进行了研究 ,证明了 :设 D为 n阶 ( n≥7)强连通有向简单图 ,且对 D的任意弧 ( x,y)有 d-( x) + d+ ( y) >n- 4,那么 D含有控制
2.
In[1] it is shown that if τ≥1 and s≥n+c/2,then every longest cycle of G is a dominating cycle and c>min{n,n+s/4-a}.
设 G 是一个 n 阶3连通坚韧图,其周长为 c,坚韧度为τ,独立数和最小次分别为α和δ,若以σ_4表示 G 的任意四点的独立集的次和的最小值,文[1]证明了,当σ_4≥n+1/2c 时 G 的每一个最长圈为控制圈且 c≥min{n,m+1/4σ_4-α},文中改进了这个结果,证明了在同样的条件下 c≥min{n,m+1/4σ_4-α+1};进而,若σ_4≥3n-1/2,则当τ≥5/3或者α≤σ+1时,G 为哈密顿图。
5) X-dominating cycle
X-控制圈
6) S-dominating cycle
S-控制圈
