All day and evening long on the Strip, one sees actual wedding parties, waiting under the harsh lights at a crosswalk, standing uneasily in the parking lot of the Frontier while the photographer hired by The Little Church of the West ("Wedding Place of the Stars") certifies the occasion, takes the picture: the bride in a veil and white satin pumps, the bridegroom usually in a white dinner jacket, and even an attendant or two, a sister or a best friend in hot-pink peau de soie , a flirtation veil, a carnation nosegay.

在拉斯维加斯大道，从白天到黑夜，当你在人行横道处刺眼的灯光下等待的时候，当你在弗兰提尔酒店的停车场烦躁不安地站着的时候，你都可以看到正在进行的婚礼派对。而这时由&西部小教堂&雇佣的摄影师会为婚礼现场做见证，拍下这样的画面：新娘戴着面纱，穿着无带浅口的白缎婚礼鞋；新郎通常会穿着白色晚礼服；在一旁还会有一两个人陪伴，是新娘的姐姐或是最要好的朋友，穿着粉红暖色的双面横棱缎，戴着一块富有调情意味的面纱，再插上一束康乃馨。

Based on the phase-space generating functional for a system with a singular higher-order Lagrangian,the quantal canonical Noether identities under the local and non-local transformation in phase space for such system have been derived.

基于高阶微商奇异拉氏量系统的相空间生成泛函，导出了定域和非定域变换下的量子正则Noether恒等式；对高阶微商规范不变系统，导出了位形空间中定域和非定域变换下的量子Noether恒等式。

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。
