Abstract: 为研究长周期地震动对大跨径桥梁地震响应的影响,分别选取了若干长周期地震波和普通地震波进行频谱特性对比;以某特大跨径斜拉桥为例,建立了有限元模型,采用非线性时程分析方法对比分析了2类地震动作用下该桥的地震响应。为控制大跨径斜拉桥在2类地震动激励下梁端的位移响应,选用了弹性连接装置和液体粘滞阻尼器2种措施对比研究了其减震效果。结果表明:长周期地震动对大跨径桥梁的位移及内力响应影响显著;在长周期地震动作用下,弹性连接装置的位移控制效率较低,并会导致结构内力的大幅增加;参数合理的液体粘滞阻尼器的控制效果具有较好的广谱性,即在普通地震动和长周期地震动作用下均有较好的减震效果。
In order to study the influence of long??period ground motion on seismic response of long span bridges, some long??period ground motions and conventional ground motions were selected, and the comparative analysis on spectral characteristics of these motions were carried out. A long span cable??stayed bridge was taken as an example to analyze the seismic response of the bridge under two types of ground motions by using nonlinear time??history method. Elastic connection device and fluid viscous damper were used to mitigate the seismic response of the bridge under two types of the ground motions. In addition, the effects of the two kinds of devices were analyzed. The results show that long period ground motions have great influence on seismic response of the bridge. Elastic connection device has lower efficiency and will introduce more seismic force into the bridge under long??period ground motion. While, the effect of fluid viscous damper is broad??spectrum, that is, it has wonderful and stable effect under both long??period ground motion and conventional ground motion with proper damping parameters

双四维时空的量子力学描述(量子力学曲率诠释)
Describe Quantum Mechanics in the Dual 4-Dimensional Complex Space-Time

Modern Physics (MP) , 2013, DOI: 10.12677/MP.2013.35022
Abstract: 自旋是微观客体的固有属性。微观客体是“限制在一定分布空间的转动场物质球”,转动频率由\"\"定义,曲率半径由\"\"定义,存在于双4维复数空间。微观客体的旋转与运动生成物质波。物质波传播微观客体空间结构及物质场宻度分布的波动信息。复数时空曲率坐标的建立,是微观客体自身物质的几何化。物质波是实在的,物质场宻度分布与概率分布可以相互映射,微观客体的非点特性及其旋转振动是量子测量中微观客体概率事件的物理源头。
Spin is the inherent attribute of the micro-object. Micro-object can be understood as a rotating matter ball which is limited in a certain spatial distribution that can not be appropriately abstracted as a particle in the mi-cro-environment. The rotation frequency is defined by \"\", radius of curvature is defined by\"\". Mi-cro-object exists in the dual 4-dimensional complex space-time. The rotation and movement of the micro-object gener-ate matter waves. Information of space structure and matter field density distribution of the micro-object can be propa-gated by matter waves. The establishment of complex space-time curvature coordinate is a geometric matter of mi-cro-object itself (geometry of matter). Matter waves are real. Matter field density distribution and probability distribu-tion of micro-object can be mutual mapped, micro-object can not be appropriately abstracted as a particle and its rotat-ing and vibration are the physical source of micro-object probability event in quantum measurement.
双4维时空中物质波的规范变换及量子力学与相对论内在联系新探
The Gauge Transformation of Matter Wave in the Dual 4-Dimensional Complex Space-Time and the New Internal Relation between Quantum Mechanics and the Theory of Relativity

Abstract:
物质波是物理波,不是概率波。自由微观客体从整体规范变换过渡到局域规范变换,通过协变导数引进规范场,尽管体现了场与微观客体的相互作用,但那是让微观客体恢复自由状态,实现规范不变性引进的抵消作用。定态波函数Ψ(x)可以分解成微观客体的各种自由运动状态——本征态(平面波)Ψn(x)的叠加。建在本征态上的坐标系是惯性系,由本征态之间的关系,将引导出惯性系之间的关系。由此,我们可以从惯性系到非惯性系的转变,为相对论与量子力学的统一找到一条可能的新的认识通道。
The matter-wave is a physical wave rather than a probability wave. Free micro object transforms from the whole gauge to the local gauge, and then brings in specification field by covariant deriva-tive, reflects interaction between field and micro object, but it has counteract effect of realizing gauge invariance in order to restore the free state of the micro object. The steady state wave func-tion Ψ(x) can be decomposed into the superstition of all kinds states of free movement of the micro object, namely, the eigen state Ψn(x) (plane wave). The system building for eigen state is inertial system. By analyzing the relationship between each eigen state, we can get the new relation between each inertial system thus we may get the transformation from inertial system to noninertial system. This work would pave a new understanding way for unifying the Quantum Mechanism and the Theory of relativity.
双4维时空量子力学描述中电子自旋、自旋磁矩
The Electron Spin and Spin Magnetic Moment in Dual-Four-Dimensional Quantum Mechanism
 [PDF]

Modern Physics (MP) , 2016, DOI: 10.12677/MP.2016.61001
Abstract:
双4维时空量子力学描述中,微观客体的自旋是场物质球自身的转动。在自身参考系,场物质球的半径由静态康普顿动量m0c定义:R0=?/m0c,转动频率为:E0= hν0;在运动参考系,场物质球的半径由动态康普顿动量mc定义:R1= ?/mc,转动频率为:E1= hν1。m,m0是微观客体的动、静质量。电子自旋S及自旋磁矩μs都可以通过场物质球模型来计算。若自身参考系就在复数空间,在闵氏4维时空观察转动场物质球的运动,生成双4维复数时空,形成场物质的波动运动,它就是德布罗意物质波。
In dual-four-dimensional quantum mechanism, the spin of micro object is caused by the rotation of field matter sphere itself. In its own frame of reference, the radius is defined as the static Compton momentum R0=?/m0c, and frequency is ν0= E0/h. In the Dynamic frame of reference, the radius is defined as the dynamic Compton momentum R1= ?/mc, and frequency is ν1= E1/h. m0 and m are the static and dynamic mass of a micro matter sphere, respectively. The electron spin s and spin magnetic moment μs both can be calculated by the field matter sphere model. If the frame of reference is in the complex space-time, and we observe the motion in a Minkowshi Space, then there will be a dual four-dimensional complex space-time. The fluctuation motion of field matter is De Broglie matter wave.
吕梁杂岩界河口群的源区特征及构造背景: 来自锆石U-Pb年龄和Hf同位素的证据
刘超,刘福来,赵国
岩石学报 , 2013,
Abstract: 华北克拉通中部造山带被认为是由东西陆块碰撞而产生的陆陆碰撞带,而吕梁杂岩位则位于中部造山带中段西缘,紧邻中部造山带与西部陆块的边界。总体上,吕梁杂岩可以分为花岗质岩体以及变质表壳岩两大类,其中前者中的赤坚岭片麻岩在本次研究中获得的锆石LA-ICP-MS U-Pb年龄为2180Ma,而εHf(t)值为+0.52~+4.30。变质表壳岩又可进一步划分为界河口群、吕梁群以及野鸡山群,其中界河口群主要由变泥砂质岩石、大理岩以及少量的斜长角闪岩组成。变质沉积岩的地球化学及Nd同位素特征说明它们的源岩为中酸性岩石,有可能是太古宙上地壳与新生酸性弧物质的混合。本次研究以及前人的研究数据都表明界河口群最下部奥家滩组中变质沉积岩的碎屑锆石最小峰值年龄在2.0Ga左右,这为界河口群形成时代的下限做出了限制,而界河口群中斜长角闪岩的顺时针近等温降压P-T轨迹则与中部造山带中~1.85Ga的主期变质作用特征一致,这为界河口群形成时代的上限做出了限制。由于界河口群中碎屑锆石的U-Pb年龄以及Hf同位素特征与同属吕梁杂岩的野鸡山群不同而与西部陆块孔兹岩带中的变质沉积岩具有相似性,因此我们推断界河口群的源岩不是来自中部造山带而是来自鄂尔多斯陆块。综上所述,在2.00~1.85Ga之间形成于鄂尔多斯陆块东缘被动大陆边缘盆地中的界河口群在~1.85Ga的东西陆块碰撞过程中沿着韧性剪切带向东逆冲从而进入中部造山带中。
