Thus, for the most part, all beams in a truss bridge are straight.

因此，在大多数情况下，所有光束在一桁梁桥是直线。

The transverse wave propagation in carbon nanotubes/polymer composites laminated structures under ultrahigh frequency(about 1THz)was studied based on the multiple-elastic-beam model.

通过多层弹性梁模型研究了碳纳米管/聚合物复合材料层合结构在高频率(1 TH z左右)下的横波传播，分析了碳纳米管的体积分数和手性对其传播的影响。

Indoor flexural fatigue tests are carried out, the results are analyzed and two types of double logarithm fatigue equation under different stress level andequivalent stress level are got. Using the fatigue equation, the fatigue performance of porous concrete and common semi-rigid base materials and cement concrete are compared, the fatigue stress coefficient which is used in the load stress calculation for porous concrete as undersurface of cement concrete pavement and the tensile strength structure coefficient which is used in the flexural stress check for porous concrete as base of asphalt pavement are obtained.

进行室内小梁弯拉疲劳试验，对疲劳试验数据进行分析，得出多孔混凝土不同失效概率下两种形式的双对数疲劳方程，利用疲劳方程，将其疲劳性能与常用半刚性基层材料和水泥混凝土进行比较，还得出了多孔混凝土作为水泥混凝土路面下面层荷载应力计算的疲劳应力系数，和作为沥青路面基层层底弯拉应力验算的抗拉强度结构系数。

It was point out that main roof can form the voussoir beam structures in the inclination, and immediate roof located at the middle\|lower section of a longwall face probably forms a voussoir arch structure with a small scale because of waste filling.

提出了大倾角条件下老顶岩层在运动中易于形成倾斜砌体结构板大结构，直接顶岩层则因上段冒落矸石充填，在采场中下段形成砌体梁小结构，并探讨了中下段小结构平衡的极限条件和结构失稳形式

Under the condition of meeting the working requirements of pumping units, aimed at lest material consumption, the walking beam is optimized.

在满足抽油机工作能力条件下，以耗材最少为目标，对游梁进行优化设计是降低抽油机成本的一个重要方面。

To meeting pumping unit can reach for different working environment demand, and to design various different models that ask to be able to at the same time accomplish convenient shortcut pumping unit meet the demand of now, select " the parameter of the walking beam pumping unit ", carry out parameter for pumping unit for research subject, design has greater meaning .

所以为了使抽油机在不同工作环境下能够达到良好的运行要求，并能方便快捷地设计各种不同型号的抽油机以适应目前的需求，选择"游梁式抽油机的参数化设计"为研究课题对抽油机进行柔性设计具有较大的实际意义，本文介绍了以三维参数化设计平台对抽油机进行参数化设计的方法。

With the consideration of the friction between warp beam and warp layers, the frequency, the dynamic characteristics and the compensation ability of the back rest system on 1515-PJR loom to warp dynamic tension is disucssed.

并在考虑织轴绕纱层之间摩擦影响的情况下，研究了送经装置的频率特性和动态特性，讨论了1515-PJR织机后梁系统对经纱动态张力的补偿能力。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
