1) eccentricity marking
偏心标记
2) label bias
标记偏置
1.
Conditional random fields were proposed to solve label bias problem based on the normalization of the sequential probability.
分析了判别式模型的标记偏置问题对序列化标记的影响,利用条件随机域模型的全序列概率归一思想解决标记偏置问题。
3) centricity recorder
偏心记录仪
4) myocardial tagging
心肌标记
1.
Methods The model of acute myocardial infarction was made by ligation of the left anterior descending coronary artery distal to its first diagonal branch in eight mongrel dogs,then dobutamine cardiovascular cine-MR and dobutamine cardiovascular cine-MR with myocardial tagging under load were performed and the motion of left ventriclar wall was analysed.
目的评价采用心肌标记技术的低剂量多巴酚丁胺负荷MR用于检测缺血心肌室壁运动异常的价值。
5) core indication
铁心标记
6) central mark

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.
