In order to improve the precision of the altimetry gravity computed by the inverse Stokes formula, the geoidal height of the innermost area is expressed as double cubic polynomial, and a formula to calculate gravity anomaly of this area is derived after the non-singular transformation is introduced.

为提高利用逆Stokes公式反演测高重力的精度，将中央区大地水准面高表示成双三次多项式插值形式，引入了非奇异变换，推导出了重力异常的计算公式。

Stamens 5–10, hypogynous or perigynous, in 2 whorls alternately longer and shorter, those opposite petals often shorter and abortive; filaments free or shortly connate at base; anthers didymous, dorsifixed in proximal 1/2, introrse, short, dehiscing longitudinally.

雄蕊5-10，下位或周位，2轮，一轮较长，一轮较短，与花瓣对生的通常短并且败育；短的花丝离生或在基部合生；花药成双，在近端1/2背着，向内，短，纵向开裂。

"Each of the million or so nephrons in each kidney is a tubule 1.2-2.2 in.(30-55 mm ) long. At one end it is closed, expanded, and folded into a double-walled cuplike structure (Bowman's capsule) enclosing a cluster of capillaries."

每个人的肾脏约含100万个肾元，各肾元为一条长约30～55公厘的极细小管，该管一端封闭，膨大，折成双壁杯状构造，包覆着一团毛细血管。
