The flow zone starts from the mid plateau, goes clockwise around the Eastern Himalayan Syntaxis, and ends at the southeast corner of the plateau with a fan-like front, which implies that the flow zone could be attributed to the escape of highly plastic upper crust material driven by gravitational buoyancy and lateral compression.

这一流滑带的前缘速度场在青藏高原东南角呈现出典型的扇形发散特征，表明整个流滑带可能起因于高塑性上地壳物质在挤压和重力共同作用下的连续性侧向逃逸。

During quiet time and substorm process, tailward flow often explored in the nearEarth magnetotail by TC1 satellite.

在磁静和亚暴期间，TC1卫星在近地磁尾，包括晨昏两侧和夜侧的尾瓣、等离子体片边界层和等离子体片区域都观测到大量来自电离层的尾向流事件。

It can be concluded that, when the jet is injected at positive angles, the initial section of the jet increases and the region affected by the jet decreases in the vertical direction; moreover, the circumfluence toward the jet exit becomes more obvious, and the separation events in the lee of the jet weaken. When the jet is injected at negative injection angles, it disarranges the flow upstream and the curvature of jet trajectories varies smartly along the flow direction.

结果表明：射流正向倾斜入射时，射流起始段增加，在垂直方向对主流场的影响区域减小，射流喷口上游位置处的&孔吸流动&更为明显，射流出口下游背风侧的分离现象逐渐减弱；射流反向倾斜入射，对上游流场的扰动增加，射流在弯曲段内曲率变化大。

Compared with the result calculated by modified Cambridge model inhered in FLAC3D,the result of elastic-viscose-plastic constructive model can reflect more creep law than modified Cambridge model,which verified the feasibility of the developed model.

通过对侧向卸荷蠕变试验的数值模拟，并与FLAC3D内置的修正剑桥模型的计算结果作比较，结果表明，弹粘塑性流变模型所得到的结果更能反映软土的蠕变规律，从而验证了二次开发的可行性。

By means of simulation the capacity of the SVC is decided while following factors, such as restraining transient voltage fluctuation of converter bus, increasing the capacity of sectionalized banks of AC filter/capacitor and improving the stability of both AC and HVDC systems at China side, are taken into account.

从抑制换流母线暂态电压波动、提高交流滤波器/电容器分组容量及提高换流站中国侧交直流系统稳定性的角度考虑，通过仿真确定了换流站装设SVC的容量。

According to the cross wind ,the aerodynamic field inside and outside an air cooling tower is numerically simulated.

对侧风条件下空冷塔内外的空气动力场进行了数值模拟，分析了塔外速度分布、压力分布，并与相应条件下理想流体圆柱绕流的情况进行了比较。

A rotary separator of vacuum cleaner is composed of a dust collecting container, an opening-closing cover, and a separating plate dividing the dust collecting container into upper space and lower dust collecting chamber.

要約 本发明属于一种真空吸尘器用的旋转分离装置，包括含有异物的空气流入其内形成螺旋流的集尘箱，可开闭集尘箱的盖，集尘箱内设有分离板，分离板与集尘箱的下侧内周面严密地结合，在分离板的下部形成集尘部；分离板是中心开有开口部的圆锥状，从上面的圆周向下倾斜形成引导部，引导部的最下端有引导异物流入到上述集尘部的流入孔。

The theory and methods of calculating the later earth pressure on deep pit was based on classical earth pressure theory, and as a result, the deformation process of enclosure wall, the influence of water seepage effects and the over-consolidation of soil were ignored.
