如果他们是苗条的，相对他们的间距，他们能是依于侧向顽抗。

If they are slender, relative to their span, they can be subject to lateral bucking.

文章通过计算分析，发现可以用支座负弯矩调幅和减小梁间距的办法，满足侧向稳定的要求。

This paper can satisfy the requirement with steady lateral buckling with the method that scales down the bending moment and abate the space between beams.

超车车辆受到的侧向力、侧倾力矩和横摆力矩在两种间距下的变化趋势有着明显差别。

The variation tendencies of the side force, rolling moment and yawing moment of the overtaking cars by two spaces are different apparently.
