Results show that vertical ground vibrations are generally greater than the lateral vibrations in the area vicinity to the central line of the railway, and decrease rapidlywith an increase in the distance to the central line.

结果表明：列车通过时，地面的竖向振动普遍比横向振动大；在靠近线路中心的区域，竖向振动随到线路距离的增加很快衰减；地面的横向振动有时比竖向的大，计算时不应忽略；地面振动强度和传播范围随地基弹性模量和埋深增加而减小。

Combining with the theory of the conservation law of mass,momentum,energy and gas explosion dynamics,the attenuation law of shock wave in excavation roadway was deduced during gas explosion.

运用质量守恒、动量守恒和能量守恒定律及爆炸气体动力学理论等，对掘进巷道瓦斯爆炸冲击波的衰减规律进行研究。

If attenuation weakens the light signal at the receiver, then data errors will result.

假如衰减减弱接收器的光讯号，随后会导致资料错误。

Novel grad attenuation was designed based on the size and intensity distribution of tested field for not exceeding limen of CCD and avoiding the spectrum information loss at tested field edge.

为防止CCD接收光强过饱和及待测场边缘光谱信息的损失，根据待测场的大小和光强分布设计了梯度衰减片，再通过窄带滤波片获得了待测场的光谱信息。

The result indicates that the output power oscillates and weakens along with increasing input power,and its oscillation period depends on the distance between the medium and beam focal point.Limiter′s limiting ability will decrease if waist size of the incident Gaussian beam and the aperture size increase.With a fixed input power scope,medium′s best limiting position will move towards the focal point if waist size of Gaussian beam and the aperture size increase,but the best limiting position will change a lot with different input power scopes.

结果表明：限幅器的出射功率随入射功率的增加衰减振荡，其振荡周期取决于介质相对于光束焦点的位置；限幅器的限幅能力随入射光束腰半径和光阑孔径的变大而减弱；入射功率范围固定，入射光束腰半径和光阑孔径增大时，介质的最佳限幅位置向入射光束的焦点靠近，但是在某些入射功率范围内会存在多个最佳限幅位置；光限幅器的箝位输出功率随光阑线性透过率的增加存在线性增加和非线性增加两个不同区域，实际应用中应在线性增加区域确定光阑孔径的大小。

By imposing continuity conditions at the soil-pile interfaces and taking account of the linear independence of trigonometric function, analytical solution of the problemns were obtained.

数值算例对排桩后面的饱和土体的竖向位移振幅衰减进行了分析，探讨了入射波频率和桩土弹性模量比等参数对饱和土中排桩隔离效果的影响。

When scalar Lyapunov function is Lipschitz continuous and regular, Matrosov theorems with respect to a closed invariant set of a class of nonlinear discontinuous systems are proposed firstly and finally, the problem of finite-time stability with respect to a closed invariant set is considered.

论文最后主要讨论脉冲系统、奇异脉冲系统、线性不确定脉冲系统、不确定脉冲系统指定衰减度以及非线性脉冲系统的奇异H∞控制问题。

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%.
