Results demonstrated that the level of ROS was greater in embryo than in aleurone layer, and only very little ROS could be detected in starch. Furthermore, the ROS produced in embryo were mainly localized inside cells but not on cell membrane.

结果表明，胚细胞产生的活性氧最多，糊粉层细胞次之，淀粉细胞几乎不产生活性氧；而且，胚细胞产生的活性氧主要定位在细胞内，细胞膜上不产生。

Results demonstrated that the level of ROS was greater in embryo than in aleurone layer, and only very little ROS could be detected in starch. Furthermore, the ROS produced in embryo were mainly localized inside cells but not on cell membrane. By contrast, ROS from aleurone layer were accumulated on cell membrane.

结果表明：胚细胞产生的活性氧最多，糊粉层细胞次之，淀粉细胞几乎不产生活性氧；而且胚细胞产生的活性氧主要定位在细胞内，细胞膜上不产生；糊粉层细胞产生的活性氧主要定位在细胞膜。

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.

With cellulose as the skeleton, gelatinized cassava starch solution and tungsten carbide were used as porogenic agent and inert densifier, respectively. The matrix prepared showed good sphericity and a logarithmic symmetrical distribution of particle size.

取得的主要结果如下：纤维素基复合层析基质的物理功能化：以再生纤维素为骨架，碳化钨粉末为增重剂，糊化木薯淀粉为制孔剂，采用&反相悬浮热再生法&和成球后去除淀粉方法，成功制备了纤维素/碳化钨复合微球，可用作层析介质的基质。

The results showed that the interlamellar spacing of improved organic bentonite was larger than that of organic bentonite and Na-bentonite,and the more the interlayer spacing of bentonite,the more advantageous the binder to the intercalation reaction between starch and bentonite,leading to higher dry tensile strength.

结果表明，PVA插层改性后的有机膨润土的层间距大于有机膨润土的层间距大于Na基膨润土的层间距，膨润土的层间距越大，越有利于淀粉与膨润土的插层反应，得到的复合粘结剂的干强度也越高。

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。

Starch sheath The innermost layer of cells of the cortex replacing the endodermis in some stems, especially young herbaceous dicotyledonous stems. Its cells contain prominent starch grains.

淀粉鞘：在部分植物的茎的皮层中，尤其是双子叶草本植物茎，代替内皮层结构的最里一层细胞，其内含有明显的淀粉颗粒。

The thermodynamics about the buckwheat microporous starch absorbing the methylene blue follows the monolayer absorption rule of the Langmuir equation. The alkalinity condition monolayer saturated adsorption is 2.9 times higher than acidic condition. When pH value rose from 4.8 to 10.8, the negative value of absorption heats increased, absorption was spontaneous exothermic process, and that was easier to carry on at pH10.8 due to the slight adsorption electrostatic repulsion.

荞麦微孔淀粉对亚甲基蓝的吸附热力学遵循Langmuir直线吸附方程的单分子层吸附规律，碱性条件的单分子层饱和吸附量比酸性条件高2.9倍；pH值从4.8增大至10.8，吸附热负值增大，吸附为放热的自发过程，且在pH10.8时吸附所受到的静电斥力小，吸附更容易进行。
