Some problems in the design of circular tubular joints are discussed in this paper. 本文探討了圓管結構相貫節點(diǎn)設計中的若干問(wèn)題。
Tubular structure is widely used for offshore structures, because in such structures, multiplanar joints are unavoidable. 圓管結構大量應用于海上或近海結構，在這種結構中，多平面節點(diǎn)是不可避免的。
Sonography showed an elongated tubular structure over the right abdomen. 超音波顯示右腹部有一長(cháng)條形管狀結構位于盲腸后面。
Thin-layer culture of cardiac vascular endothelial cells showed tube-like structure and lumen. 薄層培養心臟血管內皮細胞呈現管狀結構和管腔。
