1) dragline
[英]['dræglain] [美]['dræg,laɪn]
拖牵丝
1.
We used the YG001A single-fibre electronic tensile instrument to measure the tensile mechanical properties of the draglines,which are spun by fifteen Nephila clavata spiders of different weights,and we analyzed the relationship between weights and mechanical properties of these different spiders.
利用YG001A单纤维电子强力仪测定了15只不同体重棒络新妇的拖牵丝机械性能,分析了蜘蛛体重与拖牵丝机械性能的相互关系,并利用SEM及计算机图象处理技术分析了拖牵丝的直径,发现不同个体的拖牵丝平均直径和断裂强度随着体重的增加而增加,而屈服点应力、屈服点拉伸率、断裂点拉伸率与体重都没有相关性。
2.
We collected draglines secreted by 15 Nephila clavata Spiders when they falling down instantly,then we used the SEM to observe these draglines of single branch, take pictures, and used the Smileview software to deal with the pictures,measured and Stat the diameters of these single branch draglines.
收集15只棒络新妇瞬间下落时分泌的拖牵丝，用扫描电镜对拖牵丝单丝进行观察，并拍照，利用Smileview软件对所得照片进行处理，测量并统计了单丝的直径。
3) artificial spider dragline protein S600
仿蜘蛛拖牵丝蛋白S600
4) dragline silk
拖丝
1.
The dragline silk from an unanaesthetized spider:Argiope amoena was observed under the scanning electronic microscope(SEM).
采用非固定的抽丝方法,从一只未麻醉的悦目金蛛(Argiope amoena)的纺器将拖丝抽出,然后用扫描电镜(SEM)对拖丝进行超微结构的观察,结果表明:悦目金蛛拖丝至少具有2根、3根、4根及多根单丝纤维构成的4种不同结构,其中有一种类似弹簧的结构;另外,丝的表面还出现一种小环结构,这两种结构可能是拖丝纤维具有优良机械性能的原因之一。
2.
Synthetic gene monomer encoding recombinant spider silk protein, based on the known repetitive protein sequence and partial cDNA sequence of dragline silk, was constructed and expressed.
蜘蛛大壶腹线产生的拖丝是非常优良的纤维蛋白 ,具有独特的强度和弹性。
5) tractor
[英]['træktə(r)] [美]['træktɚ]
拖牵机
1.
In this paper, fuzzy reliability theory is used to conduct strength analysis of the tractor rotating drum shaft to solve its failure problem.
针对拖牵机转筒轴时有失效的情况,运用模糊可靠性设计理论对轴的强度进行分析,找出了转筒轴因可靠度不足而断裂的原因,并提出了解决问题的措施,为电力设备的定期检查和维修提供了有利依据。
6) rope traction
拖索牵引
补充资料：牵丝戏
1.傀儡戏。盛行于宋代。傀儡多以木制，形体约一尺上下，四肢及头部和关系部分皆缀以线，表演者在上方提线操纵傀儡动作。也叫悬丝傀儡﹑提线木偶。参阅宋吴自牧《梦粱录．百戏伎艺》。
