A detailed calculation results verified the moment and deflection of lapped connection beam is similar as that of continuous beam. So the continuous beam analytic model is suitable for analyzing roof purlins. However, how to guarantee the stability of the bearing compressed zone without the tension bar in bottom flange greatly affect the use of continuous purlins in project, theoretical analysis is carried out.

对搭接模型和均匀连续梁模型的计算结果进行对比，证明采用均匀连续梁的分析模型可较为准确地描述连续搭接檩条的内力状况；而对于仅在檩条上翼缘附近设置拉条，竖向力作用下如何保证支座区受压下翼缘的稳定性在很大程度上影响着连续檩条在工程中的推广应用，因此对其进行了理论分析。

In this paper, in accordance with Biacob plate-bending theory, analytical solutions of bending problems of rectangular plates are presented.

本文根据符拉索夫平板理论，提出了矩形板弯曲问题的解答格式，应用本文中的(8)和(9)式，可求解通常边界条件下，承受横向均布力q_0以及承受横向均布力和板边法向弯矩等组合荷载共同作用下的矩形中厚板的弯曲问题，而且使这类问题的解析解规律化。

By simplifying the mechanical model,constitutive relation defined in principal direction based on elasticity theory with different moduli was rebuilt in common ordinates,and tension-compression area was divided.

通过合理简化模型，将不同模量弹性理论中定义在主坐标系下的本构关系重新建立在普通坐标系下，进行拉压分区，从而推导了考虑自重且顶部有水平推力的不同模量弯压柱近似弹性力学解答，并由横截面上正应力为零判定了中性层的形状和位置。

The experimental and analytical results show that the axial rigidity of the corrugated pipe is 23.0 percent of the bare pipe with the same thickness and diameter,and the thermal compensation performance of the former is 2.27 times the latter's under equal-stress condition.By using corrugated pipe bundle instead of the bare pipe bundle with the same stiffness as its tube sheet,the axial thermal compensation can be increased by 40.4 percent,and the corresponding pulling-out force is 53.2 percent of that of the bare pipe bundle.

研究结果表明，波节换热管单管的刚度为相应光管的23.4%；在最大应力相同的条件下，波节换热管的轴向热补偿量为相应光管的2.27倍；在光管管束与壳体等刚度条件下，用波节管管束代替光管管束，轴向热补偿量可提高40.4%，相应的拉脱力为光管管束的53.2%。

Set up a chair three feet in front of a pull-up bar, either in a gym or in a door frame at home. The chair back should be about waist-high. Hanging from the bar, swing forward and place your left foot precisely in the center of the chair. Then float over and place your right foot in exactly the same spot.

在体育馆内或是家里门框下，找个可以拉单杠的地方，下放置一个三支脚的椅子，椅背大约到腰的高度，吊在杠上，往前摆荡且把你的左脚准确的放在椅子中间，再让你的右脚悬空放到相同的地方。

Kyrgiakos's 34th minute dismissal came after a two-footed tackle on Marouane Fellaini, who might also have seen red for his part in the incident.

双腿滑铲费拉尼之后，基里亚科斯的34分钟被红牌罚下，后者最后也看到他的中场搭档被红牌罚下。

Manchester United are anxiously awaiting the results of an x-ray after Ryan Giggs left Villa Park with his right arm in a sling at the end of an evening that also saw Sir Alex Ferguson suffer the blow of losing Nani for three domestic matches, including the Carling Cup final, after the Portuguese was sent off in the first half for a two-footed lunge on Stilian Petrov.

曼联正焦急的等待着吉格斯X光检查的结果，他在维拉公园右臂受伤。本场比赛中纳尼还被红牌罚下，要禁赛3场。其中包括了联赛杯决赛，葡萄牙人上半场双脚飞铲Stilian Petrov而被直接罚下。

The window apparently overlooked a park where there was a lake. There were ducks and swans in the lake, and children came to throw them bread and sail model boats. Young lovers walked hand in hand beneath the trees, and there were flowers and stretches of grass, games of softball. And at the back, behind the fringe of trees, was a fine view of the city skyline.

从窗户往下看，显然是一座公园，那里有一湾湖水；许多鸭子和天鹅悠然湖上，孩子们在湖边给它们喂食、试航船模；成双成对的恋人手拉着手儿漫步树下，处处有盛开的鲜花和伸展的绿地，还有人在玩垒球呢；远处树林的尽头城市的上空清晰可见。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
