萼

She picked up two pieces as usual, passing one to Sepal.

她随手拿了两块，递了一块给小萼。

Having a ridge or shaped like a ridge or the keel of a ship: a carinate sepal.

有脊或龙骨的，形状象脊或龙骨的：龙骨状萼片。

A segment of a perianth which is not differentiated into calyx and corolla; a sepal or petal.

花被片 Tepal 无花萼和花冠之分的花被片；萼片或花瓣。

And green flowers often striped purple or brown or red with the dorsal sepal incurved to form a hood.

pterostylis属的任何一种兰花，基生莲座叶丛，花绿色、常有紫色、褐色或红色条纹，萼片背部向内弯曲成盔状。

The sepal of male flower and leaf all smallish, aegis shape medicine is lain between without wool.

雄花的萼片及花瓣均短小，盾状药隔无毛。

Leaves oblong-lanceolate to narrowly oblong, 5-13 mm wide; sepal and petal laminar glands pale.

叶长圆状披针形的到狭长圆形，5-13毫米宽；萼片和花瓣片状腺体浅。

A hollow, slender, sac-like appendage or a petal of sepal, or of the clayx or corolla.

距 Spur 萼片或花瓣、花萼或花冠上的、细小的、囊状、中空的附属结构。

Leaves oblong-ovate, 10-16 mm wide; sepal and petal laminar glands black.

叶长圆状卵形，10-16毫米宽；萼片和花瓣片状腺体黑色。

The sepal s under the flower wilted.

花朵下面的萼片枯萎了。

The result of this experiment showed that expected segmentation result could be achieved by using BP network method. After taking further processing such as picking up bigger areas, erosion and dilation, etc., the result could be better. Moreover, if the teacher signals were changed, the image segmentation of peduncle or sepal could be realized easily.

试验结果表明，利用BP神经网络能较好地实现成熟草莓果实与背景的分离，经过提取大区域和腐蚀、膨胀等算法的进一步处理后，效果更好；而且，只要改变训练时的教师信号，即可实现对草莓果梗、萼片等图像的分割。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
