下延的

But as the core of the method based on an instabile downward continuation operator,the method is of inefficacy in application.

本文利用徐世浙开发的迭代向下延拓方法代替该算子，使其精度和稳定性都得到很大的提高。

According to the space domain iteration method of the Fredholm integral equation of the first kind, the wave number domain iteration formula is deduced for calculating the wave spectrum of the potential field on a lower horizontal plane.

根据第一类Fredholm积分方程的空间域迭代解法，推导出计算向下延拓水平面上位场波谱的波数域迭代公式。

Leaves sessile, lanceolate, 30-50 × 2-2.5 mm, rugose on both sides, usually 1-veined, base contracted but not decurrent, apex usually obtuse.

叶无柄，披针形， 30-50 * 2-2.5毫米，具皱纹两面，通常1脉，基部收缩的但不是下延，先端通常钝的。

Stems pubescent throughout, either lacking raised pubescent lines decurrent from margins of petioles, or lines inconspicuous

全部的茎短柔毛，或者缺乏提高短柔毛线从叶柄边缘下延，或线不明显 6

Perennial herbs; petiole hairs spreading; leaf blade papery, base not decurrent; style 2-2.5 mm.

多年生草本叶柄毛开展；纸质的叶片，基部不下延；花柱2-2.5毫米 2 F 。

Longer stamens usually without tuberculate base; connective decurrent, slightly prolonged.

长的雄蕊通常没有具瘤基部；药隔下延，稍微地延长。

Leaf blade oblong-lanceolate to linear-lanceolate, 1-2(-2.5) cm X 2-3 mm, base tapered and decurrent, apex acute.

叶片长圆状披针形的到线状披针形，1-2(-2.5)厘米X 2-3毫米，基部渐狭和下延，先端锐尖。

Female flowers pedicellate; bracteoles several, imbricate; tepals 4-6, decussate or 3 segments verticillate; interstylar nectaries or nectariferous tissue lacking; ovary 2- or 3-locular; styles 2 or 3, short, erect initially, later curved; stigma decurrent.

雌花有花梗；小苞片数枚，成鳞状；花被片4-6，交互对生或者3 枚轮生；内花柱蜜腺或分泌蜜汁的组织无；子房室2或3；花柱2或3，短，直立最初，过后弯曲；柱头下延。

Female flowers: tepals 5 or 6; carpels 3; ovary 3-locular; styles 3, free; stigma often decurrent; interstylar nectaries or nectariferous tissue present; ovules 2 per locule, pendent, anatropous, bitegmic, crassinucellar; micropyle formed by inner integument, rudimentary aril.

雌花 花被片5或者6；心皮3；子房3室；花柱3，离生；柱头经常下延；内花柱蜜腺或分泌蜜汁的组织宿存；胚珠每室2，下垂，倒生，具双珠被，具厚珠心；珠孔形成于内珠被，假种皮不发育。

Here we demonstrate by in vivo time-lapse imaging of optic tectal cells in Xenopus laevis tadpoles that enhanced visual activity driven by a light stimulus promotes dendritic arbor growth.

在此，我们使用视觉非洲爪蟾蝌蚪顶盖细胞活体延时成像证明，轻微刺激下增强的视觉活动促进树突棘生长。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
