A Hamiltonian system was constructed for the fundamental problem of the dynamic buckling ,thereby problems of critical loads and buckling modes were reduced to determinations of eigenvalues and eigensolutions in a symplectic space and a symplectic method was proposed.

针对有内压或外压的弹性圆柱壳在轴向冲击载荷耦合作用下的动态屈曲问题，构造哈密顿体系，在辛空间中将临界载荷和动态屈曲模态归结为辛本征值和本征解问题，从而形成一种辛方法。

Appropriate removal of the cervical central endplate will not undermine the axial stress of the cages or bone graft but could facilitate the synostosis.

适当地去除部分中央终板对内植物或植骨块的承受轴向应力的影响不大，同时能促进植骨块的融合，有着一定的临床价值。

You have to construct your object with a lot of control points so that it will taper properly.

在递减轴的端点的提示下，在你想让物体变窄的范围内挑选轴线的第二点。

A torsional oscillation observer based on the general observer was discussed to estimate the speed of the turbine generator. The dynamic characteristics of standard Luenberger observer with quantization effects were studied by Lyapunov stability criterion. It is concluded that the state estimate error can not asymptotically converge to zero in-the-large in presence of quantization effects.

讨论了基于状态观测器的汽轮机轴系扭振测量方法，采用李亚普诺夫稳定性判据分析存在量化效应的条件下标准龙贝格观测器的动态特性，指出由于数字系统中的有限字长效应会使观测器的跟踪性能恶化，估计误差不能在大范围内渐进收敛。

Based on true triaxial tests, this paper proposes an angle of equivalent internal friction a.

结合以往的真三轴试验结果，建议了一个复杂应力状态下的等效内摩擦角，在此基础上提出了一个考虑中主应力影响的无粘性土(c=0)的破坏准则。

These new phases involve the ai-phase (i=1, 2), where the spontaneous polarization Ps is oriented along one of the in-plane edges of the prototypic unit cell and the triclinic r-phase, where the Ps is rotated away from the diagonal of this cell.

这些新的相有：自发极化方向平行于膜面内单胞轴的ai(i=1， 2)相，膜面内外都有极化的r相。

Results show the axial gap L has great influence on the flow unsteadiness in the rotor.

结果表明，轴向间距L对转子内流动的非定常性有着强烈的影响。

When the rotor is high-speed rotating as the pump shaft, the fluid in flow channel forms the pump-up-flow under the influence of the shear and viscous force.

转子随泵轴做高速旋转，流道内的流体在剪力和黏性力的作用下形成"泵送"流。

Mostly water damage, water infiltration through the electric motor shaft, so that caused the deterioration of electrical insulation properties.

多数是水封损坏、水通过电机轴渗入电机内使电机绝缘性能恶化所致。

This new generation Impreza is built on a new longer wheelbase platform, which allows for more ride comfort and space on the inside.

这新的一代的Impreza是建立在一个新的较长的轴距平台，能让更多的乘坐舒适性和空间内。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
