In this paper, the relationship between eccentricity in stitches and structure properties of sewing threads is studied by means of multiple linear stepwise regression and the following result is obtained: eccentricity in stitches is most related to bending rigidity, linear density and friction coefficient of sewing threads.
本文运用相关分析和多元逐步回归分析对缝纫线迹的偏心量e和缝纫线的结构性能之间的关系进行 了研究,发现偏心量e与缝纫线的弯曲刚度、线密度和摩擦系数的关系最密切。
4) eccentricity e

It has been found that at the jet flow cross-section near the impingement surface accompanied by the appearance of two counter-rotating vortex pairs there emerge two eccentric peak values.
结果发现在冲击面附近的射流横截面上,伴随着两个反向旋转涡对的出现,形成了主流速度的两个偏心峰值。
补充资料：在AutoCAD中偏心圆锥与偏心圆台实体的画法
现在要画一个偏心圆锥,底面在WCS的XY平面上,圆心(0,0,0),半径100,顶点(300,0,400)在ZX平面上.
1)连接PA,PB. A(-100,0,0) B(100,0,0)
图1
在当前坐标下:
2)延长PA到C,使PA=CA;延长PB到D,使PB=DB;
3)连接CD;
4)以CD为直径画圆;
5)用XLINE命令中的二等分选项作角CPD的角平分线PO,交CD于O;
6)过O作CD的垂线,交圆于E,F;
图2
7)用三点UCS命令,取三点为:O,P,C;
8)过点O作PO的垂线GO,交PC于G;
图3
9)再次用三点UCS命令,取三点为O,F,G;
10)现在就可以画椭圆锥了!
cone-e-c-捕捉O点-捕捉F点-捕捉G点-a-捕捉P点;
图4
11)回到WCS,剖切椭圆锥
SL-选择椭圆锥-回车-XY-回车-捕捉P点.
12)删除辅助线条.
