Discussion on several ways to improve quality of knotless yarn;
提高无结纱质量的若干途径探讨
For proper use of the spilicer with the optimized specification and for upgrading the quality of the knotless yarn,starting with the assessment of the quality of the splicer,analysis is done to the mounting location,specification and specification optimization.
为了正确使用捻接器并优化其工艺参数,为提高无结纱质量提供依据,从捻接质量的评价入手,分析了捻接器安装位置,工艺参数及机械捻接工艺参数的优化,提出先捻接、再上蜡、后电子清纱的安装方式,不仅保证电子清纱器的准确检测,又有利于提高捻接质量;不同原料、纱号和捻度的纱线,应采用不同的捻接工艺,为进一步提高无结纱的质量及无结纱的可织性,满足现代高速整经、高速织造技术的要求提供了依据。
Objective To investigate the diagnosis and treatment of acute acalculous gangrenous cholecystitis (AAGC).
目的探讨急性无结石性坏疽性胆囊炎的诊断及外科治疗方法。
Certain high sharing nodes in unstructured P2P networks are vulnerable to counter congestion and bottlenecks.
无结构P2P网络中某些共享资源高的节点容易出现网络阻塞和瓶颈问题。
The overlay network of unstructured P2P system is neither regular network,nor pure random network.
无结构P2P覆盖网络并非规则网络,也非纯粹的随机网络,结点在拓扑结构中体现出非对等性,在接收查询消息的数量上具有非均衡性。
The concepts of knot,nonknotty graph and knotty graph are given at first.
给出了结、无结图、有结图等概念,然后提出了图G_0为无结图的充要条件,并论述了无结图的若干性质。
