The static natural frequencies and dynamic frequencies (under 3000rpm) are calculated by the finite element method and cyclic symmetry technique. The rotating vibration behaviors of the two models are compared. Different vibration characteristics between the two models are discussed. Geometry mismatch in a turbine blade root, which arose in manufacturing process or caused by wearing out during service, leads to contact conditions changed in fir-tree attachments. As a result, shifting of the fundamental frequencies and redistribution of stress in the blade base possibly cause failure of the blade.

在叶片—轮盘耦合系统振动研究方面，建立了带围带的叶片振动计算模型和带围带的叶片—轮盘耦合系统振动计算模型，考虑旋转离心力作用，采用波传播技术，对两种模型分别进行了整圈模态分析，得到了某汽轮机叶片模型和叶片—轮盘耦合模型在0转速和工作转速(3000rpm)下的振动模态，并对所得结果进行分析比较，讨论了整圈叶片振动模态与叶片—轮盘耦合振动模态的区别。

The earliest proposed line element error band theory is "ε-band" model,then "E-band" model was proposed and developed to "G-band" model.

最早提出的线元误差带理论为"ε-带"模型，后来又提出了"E-带"模型和在其基础上发展的"G-带"模型。

Map strip sampling has no length and width; it also doesn't require the fixed shape of sample. The method provided a convenient way to determine the region for survey and calculated the area of the strip sample, thus resolving problems with calculating the survey area in past work.

地图样带法没有长度和宽度概念，也没有规定样带的既定形状，提供了一种确定调查范围和计算样带面积的便捷方法，解决了过去调查中样带面积计算的难题。

Experimental results and values in theory were accordant well. Experimental results showed that the radius of focal spot would increase with the longer focal length, and focal depth would decrease with higher order of FZPs.

实验还发现，聚焦的焦斑半径会随着焦距的长度而增大，而聚焦深度则随着分形波带片的阶次的升高而减小，同时还对比了分形波带片和常规波带片的焦距调节方式和精度，理论研究表明分形波带片的调节焦距的方式具有更高的调节精度。

2 V-belt adjustment 4.2.1 pulley in the center of the two vertical force F imposed on the Triangle Two V-Pulley plane dislocation Two pulley axis angle is not parallel Adjustment method according to the above adjustment, the operation a few days, using the same method again adjust.

4.2 三角带的调整 4.2.1 在两带轮的中心位置垂直于三角带施加力F 两V型带轮平面错位两个皮带轮轴线不平行夹角为按上述调整方法调整后，运转数日，用同样的方法再次调整。

The calculations show that the frost-heaving zone causes damage directly to an embankment, different sensitivity of frost-heaving zone will bring different damage, and the freezing zone under a pavement is a sensitive frost heaving zone.

结果表明：冻胀带的存在是引起路基病害的直接原因，不同冻胀带范围将引起路基产生不同类型及不同规模的破坏，位于路面以下的冻胀带属于敏感冻胀带范围。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
