3 . the drop datum of largest water level in researched reaches increases relatively with length increase of dredging channel in definite condition of discharge and sediment and definite dredged sediment quantity or dredged morphology of transversal section 在一定的水沙条件和一定的挖沙量或一定挖河断面条件下，随挖河长度增加，研究西安理工大学工程硕士学位论文河段最大水位降落值相对越大。
The results show that the higher the wind velocity is , the faster the concentration of the pollutants will attenuate after the pollutants leave the tunnel portal ; while the transversal wind will result in the higher concentration of pollutants in a large range around the tunnel portal 计算结果表明，风速越高，废气离开峒口后，浓度衰减得越快；而横向风则会导致隧道两侧很大区域内的污染物浓度超标。
2 . the field ambient vibration tests induced by wind and normal traffic were carried to determine the real dynamic characteristics , including vertical , torsional , transversal and longitudinal frequencies and modal shapes , each cable tension force , as well as the figure of the bridge deck 2 .进行实桥在环境激励下的动载试验，测量该桥的竖向、扭转、横向以及纵向的动力特性，所有拉索的索力及桥面线型。
The flat - tapped beam has a uniform transversal profile in the near field and a bell - shape profile in the far field . the study of such a type of beam is of practical interest in laser material processing and inertial confinement fusion ( icf ) 平顶分布光束具有近场分布均匀，远场能量呈钟形分布的特点，在激光材料加工和惯性约束聚变等应用中常需要这种类型的光束，所以研究平顶分布光束的传输具有重要的实用价值。
Combining the lifting and transversal transportation scheme of the precast beams for a hid section of zhongjiang expressway project , this paper investigates the ay of safe and efficient intermediate lifting and transportation of beams and slabs , serving as a reference for similar projects 摘要通过介绍中江高速公路某标段的预制梁起重与横移运输方案，探讨如何安全、高效地完成梁板的中间起重运输，为类似工程提供借鉴经验。
Based on parameter - parameter surfaces intersection curve , the differential geometric properties of implicit - implicit ones are in detail in the paper . these properties include tangents , curvature vector and higher - order derivative vector in cases of transversal intersection and tangent intersection 本文在参?参曲面交线基础上，详细推导了隐?隐形式两曲面空间交线的微分几何性质，这些性质包括截交及切交下的切矢，曲率矢以及高阶导矢等。
Lognitudinal and transversal members of grillage , regarded as cuved - beam element and straight - beam element , are analyzed by finite element method , and the module for grillage static analysis is formed , by using table of information of nodal point restraint to assemble stiffness matrix for structure in restraint 将梁格纵横构件分别按曲梁和直梁两种单元进行有限元分析，引入结点约束信息表进行约束结构刚度矩阵的组集，形成了曲杆梁格静力分析模块。
In this paper , we characterized the natural partial order on the structure of regular semigroup with an inverse transversal . studying the condition about the natural partial order on it . and characterized the homomorphism between regular semigroups , discussing the conditions about the special homomorphism image 给出了有关自然偏序的的两个重要条件刻划，对具有逆断面的正则半群之间的同态进行了刻划，讨论了具有逆断面的正则半群的特殊同态像的条件。
