In wind - vehicle - bridge system vibration analysis , the effects of wind field model , wind speed , train speed , relative location of vehicle and nonlinear factors on the system vibration are analyzed by various case comparisons 采用bansys软件对风?车?桥系统的振动特性以及风场模型、风速、车速、车辆位置及非线性等因素的影响进行了多工况的对比分析。
This article studies the existion of homoclinic orbit bifurcation of sirs modle , moreover , it determines the relative location of stable manifolds and unstable manifold of hyperbolic fixed points of this system , therefore , it shows the parameter range of existing limit circle 本文讨论了具有暂时免疫传染病模型同宿轨道分支的存在性，利用melnikov函数确定了该系统双曲不动点的稳定和不稳定流形的相对位置，从而给出存在极限环的参数范围。
This research uses caxa entity design software establish 3 - d entity model and transmit it to adams design environment . this method successfully solves the problem of data interface and data transition between caxa and adams and well preserves cubage information and relative location relation . furthermore , it builds simulation model of crane mechanical system that respectively belong to three working situation of uprising 、 rotating and ranging 本研究采用caxa三维实体设计软件建立起重机的三维样机模型，将虚拟样机导入adams设计环境，成功地解决了caxa与adams之间的数据接口与数据转换技术，很好地保留了零件的体积信息与相对位置关系，实现了在adams中建立起重机起升、回转、变幅三个工作状态的机械系统仿真模型。
Dongzigou ag deposit and jianbaoshan au deposit are hosted in the sandstone of middle - proterozoic suberathem , which are developed from the proterozoic sediment metal source - rocks formed during the meso - proterozoic volcanism and reworked by the mesozoic tectono - magmatism during the formation of the metamorphic core complexes in eastern hebei . the dongzigou ag deposit has the characteristics of reformed strata - bound origin , the jianbaoshan au deposit , located in the detachment fault , is the alterated rock type . both deposits have the similar wall - rock alteration , and show the same trace element behavior , and ree patterns . they are the results of the multi - stage tectono - magmatism in the environment of continental extension in eastern hebei region . their mineralization depended on their wall rocks and relative location in metamorphic core complexs 赋存于中元古宙长城系常州沟组的洞子沟银矿床和尖宝山金矿床是由密云-都山变质核杂岩构造体系所控制的一组矿床。其成因为中元古宙火山岩浆活动形成的沉积矿源，后经中生代的变质核杂岩构造岩浆体系叠加改造而成。洞子沟银矿床具有层控迭加改造的特点尖宝山金矿床则具有破碎蚀变岩型矿床的特点。
At last , the paper proposes a method of fusing the information of relative location and absolute location for an agv , which has good performance of high measuring precision . simulation results demonstrate that the agv that use the data fusion method has less error of path following than the one that does not use the data fusion method 为验证仿真研究结果的正确性，本文还对所研究的内容进行了实验，实验结果与仿真结果基本一致，从而进一步证明了本文所提出的导航、控制、数据融合等方法的正确性。
