The top tube is an enhanced diamond oval with ridge stiffeners that counters the side-to-side flex and torsion of even the most aggressive climb.
上管是菱形截面，增强的背脊硬度抵抗最激烈的攀登中产生的弯曲和扭转力。
For the slime-tube displacement test, the diagnostic criterion of miscible conditions is the flex point on the changing curve of oil recovery with displacement pressure, but not the high oil recovery.
对于细管驱替实验，混相条件的判断标准应该是采收率随驱替压力变化曲线上的拐点，而不是高的采收率。
