e.g. We all have our eccentricities.
我们每个人都有自己的怪癖。
e.g. ...the eccentricities of British life.

1. 偏心率：采用脉冲多普勒超声心动图测量二尖瓣口、三尖瓣口及肺动脉血流流速,以三尖瓣血流频谱计算左室晚期充盈分数(AFF),AFF=A峰流通积分/(A峰流速积分十E峰流速积分),作为反映左房收缩功能的指标,左室几何构型由偏心率(Eccentricity)及左室长径/短径比

2. 离心率：地球绕行太阳并非圆形轨道,而是类椭圆形, 因此会产生近日与远日点,取其平均距离为1亿五千万公里 天文学称作1au. 1au是指地球距离太阳的平均值约等于1亿5千万公里,而离心率(eccentricity)若等于零即代表圆形轨道(e = 0) .

3. 偏心：他并进一步指出构图是向心(centricity)与偏心(eccentricity)两种相反的倾向在空间关系上达到平衡. 三等分法(Rule of Thirds):将画面作垂直、水平皆三等分(图2.),形成如九宫格的切割. 强烈的垂直或水平物体适合放置在这四条分割线附近.

4. 古怪：Nash 三十以后患精神分裂症与他的数学上的古怪(eccentricity) 有关,看来天才或多或少在性格上都与众不同,他的儿子Johnny 更早地患上精神分裂症,据 Nash 自己说,Johnny 发表了一个正确的了不起的结果,也发表了一个错误的结果.
