The ultrastructure characters of pollen grain in Brassica napus are:1There are vacuoles in cytoplasm but no starch grain in uniceelluar pollengrain.2The veget- ative nucleus of bicellular pollen grain is generally spheroidal;while the generative cell is spinde-shaped,with a big nucleus,thin layer of cytoplasmand few cell orgens,no cell wall.3In three-celled pollen grain the sperm cell is separated from the cytoplasm of vegetative cell by two layers of plasmic membrances.

Brassica napus的花粉粒，在不同发育时期超微结构的特征如下：1单胞花粉粒有一个球形的细胞核和明显的核仁，细胞质内出现液泡，缺少典型的淀粉粒。2双胞花粉粒的营养核多为球形。生殖细胞纺锤形，无细胞壁，细胞核比例大，细胞质呈薄层，细胞器少。3三胞花粉粒有一个裂片状的营养核和两个纺锤形的精细胞，精细胞无壁，以两层质膜与营养细胞的细胞质相隔。

Two inner petals bifid, or sometimes between the 2 lobes, with a smaller one, shorter than fertile stamens

2裂的两内部花瓣，有时或在2裂片，具更小的一，短于可育雄蕊之间 12

Corolla white to yellow-white, 2-4 cm, 2-lipped; tube ca. as long as calyx tube, without hairy annulus inside; upper lip straight, galeate, densely villous outside; lower lip straight, 3-lobed; middle lobe cordate, margin membranous.

花冠白色到黄色白色，2-4厘米，二唇形；筒部约与花萼等长筒部，没有有毛环带在里面；直接的上唇，盔状，在外面的密被长柔毛；下唇直，3浅裂；中部裂片心形，边缘膜质。

Branchlets with lamellate pith; calyx lobes not exceeding 5 mm; fruit stalk less than 7 mm.

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
