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。

Large division of chiefly freshwater eukaryotic algae that possess chlorophyll a and b, store food as starch, and cellulose cell walls; classes Chlorophyceae, Ulvophyceae, and Charophyceae; obviously ancestral to land plants.

主要是淡水真核状态的藻类的一个大门，具叶绿素a和b，储备食物作淀粉、纤维素细胞壁；绿藻纲和轮藻纲；明显地祖先陆地植物。

Results There were 52 cases (63%) of LA and 30 cases (37%) of MA, among which 49 cases (60%) presented with pyknotic nucleus of the basal keratinocytes above the amyloid in the upper dermis and 18 cases (22%) presented with pagetoid dyskeratosis cells among their prickle cells. More amyloid in LA and more severe incontinent of pigment in MA.

结果 82例患者中，52例(63%)为LA，30例(37%)为MA；有49例(60%)在淀粉样蛋白沉积上方基底细胞内出现核固缩现象；18例(22%)棘细胞层出现帕杰样角化不良细胞。

In the presence of DMAc/LiCl solvent, disproportionated rosin glycide-cassava starch ester was synthesized from cassava starch and modified disproportionated glycide ester under microwave irradiation. The effect of reaction conditions on the degree of substitution has been discussed.

在微波辐照下，以DMAc/L iC l为溶剂体系，歧化松香缩水甘油酯和木薯淀粉亲核开环反应得到歧化松香缩水甘油木薯淀粉酯，探讨了各反应因素对产物取代度的影响。

At mononucleus microspore stage,cytoplasm were thick and organella,such as mitochondria,endoplasmic reticulum were abundant.At two\|nucleus and three\|nucleus stage,there were a lot of starch grains.

结果表明，85 EA、89 AR、TA 与恢复系杂交F1 代小孢子发育表现出明显的可育特征：在单核期，细胞质浓，细胞器丰富，线粒体、内质网等十分发达，二核及三核期淀粉粒数量多。

The grain filling of superior spikelets was a continuous progressing process without interruption: Free nucleus→endosperm cell formation→endosperm cells differentiating into aleurone layer and starchy endosperm→composition and storage of reserve materials such as starch and storage proteins.

水稻强势籽粒的胚乳发育是一个无间断的连续过程，经过游离核期→胚乳细胞化→胚乳细胞分化发育成糊粉层和淀粉质胚乳→合成和累积淀粉、蛋白质等贮藏物质，约在20d以内完成胚乳发育的全过程，不同强势籽粒的胚乳发育进程大体一致。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.
