These design alterations form the basis for the machine's extreme dynamism in hard dragline operation的復數(shù)形式" target="_blank">operations. 這些設計變更形成了該機器在艱苦索斗鏟作業(yè)時的特殊物力基礎。
The selection of dragline is a key problem to be handled when applying dragline for open cast in surface mining. 露天礦應用拉斗鏟倒堆工藝的關鍵問題首先要做好拉斗鏟的選型。
Araneus diadematus dragline silks are studied.The assemble and shape structures of the dragline silk is analyzed . 以大腹圓珠牽引絲為研究對象,分析了蜘蛛絲的聚集態(tài)結構特征和形態(tài)結構特征。
Several types of spider silk, i.e. dragline silk and capture silk, and silkworm silk are compared. 蠶絲與蜘蛛絲的一些型態(tài)，如牽引絲與補抓絲之間的比較。
Dragline silk, which spiders use to drop themselves down and which form the “spokes” on a web, are five times as strong, by weight, as steel. 新的人造蜘蛛絲用途將極為廣泛，包括用來制造防彈衣及外科手術用的縫合線。
Finally, decreasing the revolution angle and increasing the bucket fill factor are effective ways to improve the operation efficiency of dragline. 減小拉斗鏟作業(yè)回轉角和加大拉斗鏟斗容的滿斗系數(shù)是提高拉斗鏟作業(yè)效率的有效途徑，為國內外拉斗鏟的研究提供了具體的分析方法和理論依據。
