It has been found that the microhardness HV and the mean positron lifetimeexhibit quasi-periodical oscillation when the number of the fatigue cycles is increased.

通过对不同循环次数的热疲劳样品的正电子寿命谱和表面显微硬度的测量，发现表面显微硬度HV和平均正电子寿命τ随疲劳循环次数N的变化呈现出类周期振荡特征。

The results show that the atomic population is time-independent provided that the atoms are in |β11〉 state. For the other three Bell states, there will appear the periodical collapse revival of atomic populationif the initial mean photon number reaches some special values. With the increase of the initial mean photon number, the oscillation frequency of the time-evolution of atomic population increases correspondingly, and the amplitude decreases. The degree of the entanglement of the two-mode entangled coherent field has no

结果表明，当双原子体系的初态为|β11〉时，原子布居均不随时间变化；当双原子体系的初态为|β00〉，|β01〉或|β10〉且初始平均光子数达到一定值时，演化特性呈现周期性的崩塌-回复效应，并随初始光子数的增加，其演化曲线的振荡频率增大，振幅减小；双模纠缠相干光场的纠缠程度不影响Rabi振荡频率，但对振幅影响显著； Kerr介质与光场耦合系数达到一定值时，对Rabi振荡频率和幅度及原子布居的崩塌-回复周期产生强烈影响。

Thefluctuation of phase presents a picture of periodical collapses and revivals with theperiod 〓.

系统的相位涨落呈现出周期性的崩塌与恢复，其周期为〓2π。

However, when we approve the function of 「The Earth Citizen 365」 child periodical content to promote children's multicultural ability and international view. It's almost perfect, except the content mainly display mainstream culture reading materials. Moreover, the appearance of male and female in the picture and sentence is imbalanced. The professional type and family duty of male and female in the content also has sex-role stereotypes question. Children's books redactors may refer above discoveries when they decide the arrangement of the picture and the sentence in the content.

然而，在肯定「地球公民365」儿童刊物读物内容对於提升儿童多元文化能力与国际视野的协助之余，较为美中不足的是，读物内容中较少为儿童介绍非主流与弱势族群文化的特殊性，读物图文的呈现也有较以男性角色为主的倾向，至於男女两性职业类型与家庭分工型态则有稍具有刻板化的问题存在，值得做为各儿童读物出版社未来在编辑读物内容时的参考。

It is important to reduce the span of the hard roof to avoid its impact load on supports. However, at longwall top coal caving face, the periodical weight of roof is a main factor that crushes the top coal, which is beneficial to the top coal recovery. How to use the roof pressure safely is of crucial importance in top coal caving. Based on field monitoring, theoretical analysis of strata movement, the numerical model of compound structure of hard roof stepped cantilever and the top coal cantilever beam is built, and the parameters of the model are also determined. The elasto-plastic finite element method is used to analyze the effect of hard coal fracture under the abutment pressure of hard roof, and the cracking coefficient is defined according to the stress state of the element.

通过对岩层移动的现场观测，建立了&两硬&条件综放采场台阶悬臂—悬臂梁组合的煤岩组合结构力学模型，并以此煤岩结构为基础，建立&两硬&条件综放采场顶煤压裂的有限元数值模型，分析了坚硬顶板不同来压步距对坚硬顶煤的压裂效应，并确定了合理的支架阻力，从而对坚硬顶板进行有效的控制，消除坚硬项板对采场的冲击隐患，同时保证采场矿压对坚硬顶煤的有效压裂，达到提高顶煤回收率之目的，由此形成了坚硬顶煤、坚硬顶板条件下综放采场围岩控制的基本理论和方法。
