该改进的轴承是环形的，具有与悬挂接头的壳体或可移动的承窝的内部相配合的外部尺寸。
The improved bearing is annular, having an outer dimension sized to seat within the housing of a suspension joint or movable socket.
由此我们可以得出结论，除了在极特殊情况下，如那些没有尺寸的外部空间，假定流体是连续体是可取的。
It may thus be concluded that the assumption of a continuum is valid for fluid flow except in the rarest conditions, such as those encountered in outer space.
重点是考虑材料、几何尺寸、外部荷载等的随机性对其进行了结构的可靠度评估。
Focus is to consider the randomness of materials, geometry, external load and so on evaluate the reliability of concrete filled steel tube arch bridge.
