梯形

When human histiocytic lymphoma cell line, U937 cells, was treated with cadmium for 12 hours, evidence of apoptotic features, including change in nuclear morphology, DNA fragmentation, formation of DNA ladder in agarose gel electrophoresis, and phosphatidylserine externalization, were obtained.

人淋巴瘤细胞株（U937）暴露于镉12小时后，细胞呈现典型的凋亡特征，包括细胞核形态学改变、DNA梯形条带的形成、及细胞膜磷脂酰丝氨酸外翻转。

The answer, says Dr Kroo, lies with birds. Since 1914, and a seminal paper by a German researcher called Carl Wieselsberger, scientists have known that birds flying in formation—a V-shape, echelon or otherwise—expend less energy.

克鲁教授称这个设想是受到鸟类的启发。1914 年，一位名叫卡尔维塞尔斯伯格的德国研究员发表了一篇具有重大意义的论文，科学家们从中得知，鸟类在飞行的时候排成 V 字，梯形或倒过来时，会节省体力。
