求翻譯：梁式機翼的桁條,一般都用薄鋁板制成,他有開口和閉口兩種.開口截面桁條的穩定性很差,而且由于壁很薄,實際上不能參與承受機翼的彎矩.閉口截面的桁條,穩定性較好,可以參與承受機翼的彎矩.但是這種桁條與蒙皮鉚接時,有兩道鉚縫,對保持機翼表面光滑不利.是什么意思？ 待解決

The beam plate wing purlin, all uses the thin aluminum sheet to make generally, he has the aperture and the blind tuyere two kinds. The open cross section purlin stability is very bad, moreover because the wall is very thin, in fact cannot participate in the withstanding wing the bending moment. The
