1) accidental eccentricity
偶然偏心
1.
codes which consider accidental eccentricity in any case,it is not very strict in our codes to consider accidental eccentricity under special conditions.
针对《建筑抗震设计规范》规定的平面扭转不规则结构,考查了水平地震作用下不同结构效应受偶然偏心影响的增幅变化规律,在分析结果的基础上,对现行规范的相关规定提出了改进建议。
2.
In this paper,dynamic analysis are performed on regular structures with regard of accidental eccentricity.
本文对均匀对称结构进行了偶然偏心下的静力和动力分析,得到偶然偏心对结构地震反应的影响规律。
3.
The accidental eccentricity is considered for regular structures and ignored for irregular structures in seismic design according to the Chinese codes,while it is considered for both regular structures and irregular structures according to some codes such as UBC,FEMA302s,etc.
目的通过算例分析考查偶然偏心对非规则结构地震效应的影响显著性。
2) accidental drift angle
偶然偏航角
3) displaced dipole
偏心偶极子
1.
In this paper, a displaced dipole model is used to calculate the field distribution of a two-sphere system, the results of which is compared with those obtained through the finite element method.
将偏心偶极子模型用于计算两球系统电场分布,并将所得结果与用有限元方法的计算结果进行了比较,当两球最近点的距离比球半径大时,偏心偶极子模型是适用的。
4) maximum accidental drift angle
最大偶然偏航角
5) off-centered dipole
偏心偶极子;偏心振子
6) eccentric dipole coordinates

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.
