扁球体

扁球体水准面与水准椭球面形状差异的研究

A Study of the Shape Difference between the Level Surfaces of the Oblate Spheroid and the Ellipsoid

其形状呈扁球体，被一个辐射带所包围着，因为太阳照射到地球上的带电离子被困在了地球的磁场之中。

Oblate in shape , it is surrounded by a belt of radiation because of charged particles from the Sun being trapped in its magnetic field .

扁长球体是将一个椭圆体依其主轴旋转而成的。

A prolate spheroid is generated by revolving an ellipse about its major axis .

由于链球菌所导致的喉咙扁桃体感染。扁长球体是将一个椭圆体依其主轴旋转而成的。

An infection of the oral pharynx and tonsils by streptococcus . a prolate spheroid is generated by revolving an ellipse about its major axis .

地理和投影坐标系都包含对地球形状的假设（一个略扁的球体）；这称为大地基准点。

Both geographic and projected coordinate systems include a definition of the assumed shape of the earth ( a flattened sphere ); this is called the geodetic datum .

测量结果表明竖直圆管稳定层流泡状流中变形气泡可被近似成以一定倾角稳定上升的扁椭球体，并得到了计算气泡变形比的经验公式。

The results showed that the bubbles are similar to the oblate ellipsoids which rectilinear rise with an incline angle in fully developed bubbly laminar flows in vertical pipes .

由于地球为扁椭球体，平面和球面定位模型只适用于覆盖范围较小的探测网。因而地闪定位只有采用椭球面定位模型方可保证精确定位。

The earth is a flat ellipsoid , thus the plane and sphere location model are suitable for small network , and oblate spheroidal earth model is suitable for lightning location .
