Two t-sections are battened between the stems . 在两个T形断面梗部之间用钢钣条连接。
These tubes are not necessarily of circular cross-section . 这些毛细管不一定具有圆形断面。
Only a few sectional shapes are sensitive to this condition . 只有少数断面形状对这种情况是敏感的。
This meter consists of a conduct having an enlarged section . 这种流量计包括一个具有断面扩张的导管。
Radioactivity is found on both sides of the failure plane in all cases . 破断面的任何一侧都发现有放射性。

A segment of the box corner was removed with a hole saw in order to permit an examination of the crack . 为了对裂纹进行检查，用圆孔锯从箱型断面拐角处锯下一部分。
The etched section also reveals that multiple weld passes were made over the top of the original submerged arc weld pass . 从酸蚀断面还可以看出：在原自动埋弧焊的上面覆盖有多层焊道。
Normally small diameter sections produced by unredrawing have inferior properties with an apparently reduced extension at failure . 在正常情况下，拉丝做成的小直径断面具有破坏时伸长显著减少的不良性质。
