绯闻女孩第四季第11集城中大闹播出时间：2010年12月6日B和Dan联合起来寻找失踪的Juliet，Chuck怀疑Lily隐瞒他了一些事情。

Through coupling of interaction forces between vehicle, track and bridge, equations of motion of the spatial coupled vibration of the vehicle-track-bridge system are deduced. The spatial random vibration responses of vehicle, track and bridge are obtained by employing the novel explicit integration algorithm.

通过车辆、轨道和桥梁之间相互作用力的耦合，建立了车辆-轨道-桥梁系统空间耦合振动的运动方程，并通过新型显示积分方法进行求解，得到车辆、轨道和桥梁的空间随机振动响应。

The Level-Set approach was adopted to deal with some factors such as deposited track, liquid/ vapor interface, which considered surface tension gradient ( the major driving forces for the melt flow), interface curvatures, buoyancy and convection heat loss.

通过水平集（level set）方法处理熔积轨迹、液/气界面等因素，考虑了熔体流动的主要驱动力表面张力梯度、表面曲率以及浮力等。

Braking forces and tractive forces are taken into considerations in case of single-track traffic.
