对棉条圈条过程定量地进行了动力学分析，以棉条所受曲线斜管摩擦力最小为目标函数，基于变分问题直接法原理设计出圈条盘螺旋形曲线斜管。这种螺旋形曲线斜管充分利用圈条盘的转动对棉条产生的离心力甩摆作用，使棉条所受曲线斜管摩擦力较小，从而使出条更顺畅；在一定程度上降低了圈条盘螺旋形曲线斜管堵眼频率与条筒乱条几率，使其更适应现代并条机生产高速化的要求

These were raised underinducing condition to test if any morphology and structure changes. Twenty two Arabidopsismutants had various changes in morphology and anatomical structures. Twenty mutants hadlow germination rate from 10% to 60%, of which 2 had survival rates at 0% and 50%. Fivemutants occurred structure changes in the hypocotyls or stem. One of these lines, namedarris-stem, showed some unique changes: slower growth rate in comparison with the wildtype from germination to florescence; serrated margin of leaf blades, spiral rosette; morebranch in the bottom part of the stem, shorter nodes, twisted stem and branch. There were oneor several arrises along the stem. Across sections of the arrises showed one or several compactcells lumps which were round, made up of several layers of cells, looked like vascular-bundle.
