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。

The top coal fracture is described distinctly under the condition of different roof span and mining technology parameters. Through orthogonal experiment of numerical simulation, the rational pretreatment span of hard roof is determined, and the rational working resistance of support is selected also. As a result: the hard roof is effectively controlled not only to protect the working face but also to promote the caving of hard top coal to increase the recovery ratio.

在有效控制坚硬顶板的基础上，利用数值模拟正交试验法，研究了采高、采放比、支架阻力、放煤步距等工艺参数对顶煤压裂效果的影响规律，从而对工作面工艺参数进行优化；并根据实验所得放煤方式对块体顶煤的适应性规律，选择&两硬&综放面的放煤工艺，从而形成了系统、完善的&两硬&条件综放工艺。

In the first part of this thesis, I will give a general description to synchrotron radiation source and beamline design; and then the comparison to the difference in the designs of hard X ray and soft X ray beamline is given; some detailed features on hard X ray beamline design is also discussed especially in this part.

会走以后，可穿硬底鞋，但不可穿硬皮底鞋，以胶底、布底、牛筋底等行走舒适的鞋为宜。

Butler brought a wrongful-death action against the Newark Country Club, claiming the facility was negligent when it failed to childproof the pond after the expansion project in 2000. Butler admitted that Jeremiah had been trespassing, but she argued that children are owed a higher standard of care by landowners even if they are trespassers.

Butler 认为这场事故的原因在于Newark乡村俱乐部，他认为乡村俱乐部在200年扩建的时候疏忽了对于儿童的防范保护，Butler承认她的孩子是硬闯禁区的，但是她争辩说即使当孩子们是硬闯的时候，对于儿童也应该有更高的防护标准。

The results showed that the damaged starch contents of hard wheat were 20% higher than that of soft wheat under the same processing condition, and the damaged starch contents would be increased ...

研究结果表明：硬麦加工后淀粉破损率高，而软麦则相对较低，硬麦粉的淀粉破损率较软麦粉高出 2 0 %左右；面粉越细则淀粉破损率越高；研磨道数越多，研磨强度越大，淀粉破损越严重；齿辊所造成的淀粉破损程度要比光辊为重，但差距不是很大；撞击机在正常生产时对淀粉破损影响较小，如反复撞击也会使破损淀粉增加，但其影响程度较研磨强度缓和。
