The result showed that there were 8 types of mutative treats on cotyledon, including light-yellow cotyledon, yellowish cotyledon, trump-shaped cotyledon, multilobed cotyledon, non-cotyledon, single-cotyledon, tricotyledon and quadrcotyledon.

现代先进战斗机和战木导弹常具有细长前体，大攻角条件下前体背风面会形成非对称涡结构，从而产生很大的侧向力和偏航力矩，这会严重影响飞行器的可操纵性和飞行安全。

Inefficient supervision on the marketing products causes the problem that low quality products elbow with high quality Ones, reducing the producer's benefit expectation. The official-run certification agencies make the monopolistic interest privatized or the producer's interest transfered to their own, which disagree with the principle of Pareto optimality.

认证取费过高，增加了生产者的固定成本；认证后对产品市场监督不力，又使市场上劣品排斥正品，降低了生产者收益预期；认证机构的官商性使国家垄断利益私有化，或生产者利益向认证机构转移，不符合帕累托最优原则。

事实上，所有动植物的光生物行为——光合作用、向光性、趋光性、光周期和视觉——都利用这一辐射范围的能量。

The high abundance and large colony size of Porites at shallow waters might be ultimate factors for the snail's preference, while larval phototaxis and larval preference on Porites may be proximate mechanisms.

推测微孔珊瑚在浅水区丰度高和群体大可能是造成紫口珊瑚螺对深度有不同偏好的远因，而幼生向光性和对微孔珊瑚的偏好可能是造成此现象之机制。

A Halberstam paragraph usually filled a page, unfolding portentously towards some great quotation that glimmered in the final line.
