查询词典 G-string

A set S of vertices in a graph G is a dominating set of G if each vertex of V-SV(G is adjacent to some vertex of S.

图G的点集S如果满足：V|G|-S中每个点相邻于S中的某个点，则称点集S是一个控制集。

We obtain that if any 〓 is discrete or elementaryand 〓 satisfies Condition A,then the algebraic limit G of group sequence 〓is discrete or elementary.

首先，我们不再仅仅考虑离散非初等群集〓的代数极限G，而是离散群或初等群群集〓的代数极限G，我们对〓上〓变换群中斜驶元及其不动点进行了细致研究，注意到任意一个斜驶元存在一个仅仅含有斜驶元的领域，从而证明了初等群群集〓的代数极限G仍然是初等群，进而我们得到了一个代数收敛定理：如果任一〓是离散群或者初等群并且〓满足条件A，那么，群列〓的代数极限G一定是离散群或者初等群。

然后在此基础上综合运用多方面的知识，进一步给出了满足条件|Aut∶Paut|=1，p或pq的有限群的完全分类，其中Aut是群G的自同构群，Paut是G的幂自同构群，p，q仍是不同的素数。

Methods Forty weanling Wistar male rats were divided into four groups. In one group, 1%sulfadiazine was added to regular diet (vitamin K 50 μg/kg) to induce vitamin K deficiency. In the other three groups, the vitamin K levels in diets were 50 μg/kg, 300 μg/kg, 2 550 μg/kg respectively.

MATERIAL AND METHODS: Thirty 30 healthy Sprague- Dawley adult male rats were randomly divided into 3 groups: control, alcohol 7.5 g/kg and alcohol 7.5 g/kg ＋ vitamin A 50 μ g/kg. Alcohol and vitamin A were administrated to the rats for 13 weeks by a gastric tube. The sperm counting ,motility and the percentage of abnormal sperm were observed. Serum testosterone was determined. The patholgical changes of testicle tissue of rats were observed by light and electron microscopy.

The electron paramagnetic resonance parameters g factors g(subscript //), g(subscript ⊥) and the hyperfine structure constants A(subscript //) and A(subscript ⊥) for the tetragonal KTaO3:Cu(superscript 2+) crystal are theoretically studied in this work.

Times of signal-to-noise ratio being taken as detection limit, the limits of 3 kinds of pesticides detected by this method were: Aldrin of 0.3 μg/kg, Dieldin of 0.5 μg/kg and Endrin of 0.3 μg/kg respectively.

以3倍信噪比为检出限，采用该方法对3种杀虫剂的检测限分别为：艾氏剂为0.3μg/kg；狄氏剂为0.5μg/kg；异狄氏剂为0.3μg/kg。

A number of v=0~57 vibration levels were determined and assigned. The levels cover more than 99% of the potential well depth of the state. No evident autoionization was found related to the levels belonging to the 13 g- state above the ionization threshold, implying the distinct character of the doubly excited valence state from the Rydberg states.

并发现13 g-态能级即使超过电离限时亦无明显的自电离倾向，反映了双电子激发态不同于里德堡态的独特性质。13 g-态是碱金属双原子分子电离限以下唯一的3 g-对称性的态和电离限下唯一较纯的双电子激发态，这些结果为分子结构和量子化学的定量研究提供了重要的信息；（2）通过检测Na 3d 3p原子荧光，观察到Na2分子的33 g和43 g+态在3s+3d解离限以上的预解离能级及其转动线宽加宽等。

In this paper, we discuss some recurrence relations and congruence properties of Bell polynomial, and give a class of recurrence relations satisfied by GSN pairs. Furthermore, we givethe definition of extended GSN pairs Gand G, so we unify the binomial coefficients, Gaussian coefficients, and Stirling numbers.

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
