Using pressure roll eccentricity of the rotating structure of the squeeze: roller pressure, strong spiral feeder synchronous rotation and autobiography, so that the raw materials for the time being all the pressure into the ring mold.
采用压辊旋转的偏心挤压结构：压辊，强力螺旋给料器同步旋转并自传，使所供原料能及时全部被压入环模。
The effect of the expansion and the anti-thrust ring on the stress and deformation of the spiral case structure are analyzed respectively. It is found that the presence of expansion reduces in large extent the stiffness of the spiral case as a supporting structure of the turbine. It affects the safe stability of the hydro generator.
3通过对是否设置伸缩节与止推环的方案对比分析，发现设置伸缩节在一定程度上降低了流道系统的轴向刚度和抗扭转刚度，影响水电机组的安全稳定运行，设计中应予以重视。
As another bold hypothesis, the quark is created by curling a train of longitudinal quantum waves, in which the quantum waves are connected end to end, forming a closed recurring wave ring, namely a complete chain running in a distorted manner that is similar to the human DNA spiral structure.
这里再次大胆假设，夸克是由一个段量子纵波卷曲而成，这列量子波首尾相连，形成一个闭合的循环波环，一个扭曲运转的完整链条，类似于人类DNA的螺旋结构。
