Effects of Some Topological Ingredients on the Evolutionary Ultimatum Game

This study aims at figuring out the crucial topological ingredients which affect the outcomes of the ultimatum game located on different networks,encompassing the regular network,the random network,the small world network,and the scale-free network.With the aid of random interchanging algorithm,we investigate the relations between the outcomes of the ultimatum game and some topological ingredients,including the average range,the clustering coefficient and the heterogeneity,and so forth.It is found that for the regular,random and small-work networks,the average range and the clustering coefficient have evident impacts on the ultimatum game,while for the scale-free network the original degree heterogeneity and the underlying rich-club characterizations are the mainly important topologica ingredients that influence the outcomes of ultimatum game substantially.     

Phase Diagram of Transverse Spin-2 Ising Model with Longitudinal Crystal Field

The transverse spin-2 Ising ferromagnetic model with a longitudinal crystal field is studied within the mean-field theory. The phase diagrams and magnetization curves are obtained by diagonalizing the Hamiltonian H_i of the Ising system numerically, and the first order-order phase transitions, the first order-disorder phase transitions, and the second-order phase transitions are discussed in details. Reentrant phenomenaoccur when the value of the transverse field is not zero and the reentrantdiagram is given.     

非对称圆环拍的特性研究

建立微小非对称圆环点冲击下拍的理论模型,通过实验验证其有效性。微小非对称圆环是分析大钟拍现象的简化模型,微小非对称圆环的每一对径向振动模态的固有频率非常接近,这对模态互相干涉下出现拍现象。最后利用拍的理论模型绘制沿圆周拍的分布图,详细分析拍的分布特性,为校正钟的拍频声提供理论依据。     

环形调液阻尼器振动控制中拍的研究

对环形调液阻尼器减振控制中的拍现象进行研究,分析了环形调液阻尼器对结构纯扭转振动控制中的拍现象,分别考虑无阻尼结构体系、主体结构有阻尼而CTLCD无阻尼的体系及主体结构和CTLCD中均有阻尼的体系,从数学角度对拍现象发生的机理进行解释.研究结构表明,当拍现象发生时,主体结构的振动不仅不会受到抑制,有时反而会加强;当环形调液阻尼器的阻尼增大到一定程度时,拍现象会消失;对于受廹振动,发生拍现象时,由于结构反应的瞬态部分不能得到迅速衰减,结构的瞬态响应将会占结构响应的很大一部分,如果仅考虑结构的稳态响应会带来较大的误差.     

Measurement of K β K /α values using proton beamvalues using proton beam

The Measurement of K _β K _/α intensity ratios are measured in some 3d shell elements by using a 2 MeV proton beam along with a high resolution Si(Li) detector. The present Measurement of K _β K _/α intensity ratios are in good agreement with Scofield modified theoretical values, thus supporting the basic assumptions in that theory. From the present Measurement of K _β K _/α intensity ratios, it is evident that due to chemical effects, the experimental Measurement of K _β K _/α intensity ratios will be increased while they will be decreased due to the presence of simultaneous M-shell vacancies which are produced due to proton excitation.

二甲基亚砜-水混合溶液的等效介电常数特异性研究

在2.45 GHz下利用微扰谐振腔法测量二甲基亚砜(DMSO)-水(H₂O)混合溶液的等效介电常数过程中, 发现混合溶液等效介电常数虚部大于其中任一组分的介电常数虚部的特异现象. 分析表明, 这种特异性现象的发生主要是由于DMSO与H₂O混合后溶液的高频摩擦项大于混合前引起的. 因此, 经典混合物介电常数公式需要进行适当修正才能较好地适用于这类特异性问题计算.
