对萼的

Stamens 2 to many, usually as many as calyx lobes and opposite them or twice as many.

雄蕊2到多数，与萼裂片通常同数并且与之对生或为萼裂片数的两倍。

Sepals 4 or 5, connate at base or to ± half their length.

萼片4或5，他们的期间的对±一半的在基部合生或。

The cypsela size and variation of 6 genera (32 species) about Compositae of eastern Qinghai-Tibetan Plateau were studied and the environmental facts were discussed.

对青藏高原东缘6属32种菊科植物连萼瘦果的大小及其变异进行了比较，并探讨了影响连萼瘦果大小变异的环境因素。

Sepals (2-)4 or 5(or 6), imbricate or decussate or rarely wholly united in bud, inner ones sometimes petaloid.

萼片(2-)4-5(-6)，在芽期覆瓦状排列或交互对生或很少完全合生，内部的萼片有时花瓣状。

Comparing two Cd-accumulating plants the Eichhornia crassipes accumulating ability is 5-7 times of Hosta ventricosa.

从这两种植物富集镉能力的比较来看，凤眼莲对镉的富集能力是紫萼玉簪的5～7倍。

Eichhornia crassipes and Hosta ventricosa is used as experimental material to study Cd stress on the two plants growth, chlorophyll content, MDA and root peroxidase activity and other physiological indicators to investigate the effect of Cd on the toxic effect of higher plants,with a view to Cd pollution Phytoremediation providing a theoretical basis.

以凤眼莲和紫萼玉簪为实验材料，研究镉胁迫对凤眼莲和紫萼玉簪的生长、叶绿素含量、丙二醛含量及根系过氧化物酶活性等生理指标的影响，探讨镉对高等植物的毒害效应，以期为重金属镉污染的植物修复技术提供理论依据。

With the method of population accumulative culture,the effect of initial population density on the formation of resting eggs of freshwater rotifer,and on the rates of mictic female and fertilization was studied.

应用群体累积培养法，研究了种群起始密度对萼花臂尾轮虫休眠卵的形成及与之相关的混交雌体百分率和受精率的影响。

This suggests that the effects of temperature on growth of the two coral species were different. Growth rates of S. hystrix at 25℃ were stable and higher than those of S. pistillata. However, the effects of temperature on growth rate of S. hystrix may be modified by other factors (e.g., mesocosm effect) in higher or lower temperatures. The mortality of S. pistillata in three temperature treatments was very low, while the partial mortality of S.

这些结果显示，两种珊瑚在不同温度下的生长反应有所差异，在适温环境下，尖枝列孔珊瑚的生长稳定且高於萼柱珊瑚，但萼柱珊瑚却会受到其他因素影响；在较高和较低温时，萼柱珊瑚生长没有受到生态箱效应影响，而温度对於尖枝列孔珊瑚生长率的影响可能受到生态箱效应而改变。

Male flowers: sepals mostly 5, imbricate to valvate, free; petals 5, smaller or nearly equal to sepals; disk glandular, usually 5, and opposite sepals; stamens 10-20; filaments free, inflexed in bud; anthers muticous; pistillode absent.

雄花： 多数的萼片5，覆瓦状到镊合状，离生；花瓣5，小或近等长于萼片；花盘具腺，通常5，与萼片对生；雄蕊10-20；花丝离生，在芽中内折；花药钝；无退化雌蕊。

Calyciflorus clones were cultured at 15℃, 20℃, 25℃and 30℃with 3.0×106 cells/mL of Scenedesmus obliquus to investigate their differences in life history characteristics and their responses to increasing temperature.

结果表明，温度对萼花臂尾轮虫存活率和繁殖率的影响在不同克隆间存在着差异。20℃和25℃下，四个克隆轮虫的世代时间和净生殖率均分别无显著的差异；20℃、25℃和30℃下，四个克隆轮虫的平均寿命和出生时的生命期望亦然。

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。
