Probably it was more small starchgranules in endosperm rather than low protein content in grains that led to a floury ornearly floury endosperm. 2 Wx gene null could decrease amylose content.

Wx基因变异类型的直链淀粉含量都低于正常类型，各种Wx基因变异对直链淀粉含量的降低效应表现出3个基因变异＞2个基因变异＞1个基因变异的趋势。

3Glass capillary gas chromatography is used in the analysis of n-paraffin distribution of the diesel,and according to the results of the cold filter plugging point test ,it is conclude that the impressibility of DFI to fuel is not only connected with the alkyl side chain and the polarity group of medicine oneself ,but also the n -paraffin distribution of the diesel ,the component ,technology and directions for producing of fuel and so on.

该方法具有合成线路短、产率高、成本低的特点；(3)通过使用毛细管气相色谱法测定柴油中直链烷烃的组成与含量，及柴油冷滤点(Cold filter plugging point 简称CFPP)的测定得出结论，DFI 对柴油的感受性不仅与药剂本身的烷基侧链、极性基团有关，也与柴油的直链烷烃的含量、馏分组成、加工工艺等有关。

A higher content of undissolved substance of DMSO and amylose and a lower content of intermediate fraction may be important reasons causing different rice quality between varieties with the same apparent content of amylose.

DMSO不溶物和直链淀粉含量高、中间成分含量低可能是导致同等表观直链淀粉含量籼稻品种具有不同米质的重要原因。

This paper introduced the discovery of RNAi, amylosynthetase and quality improvement in amylocellulose content by RNAi, and the problem about RNAi technology also was preliminarily discussed in this paper.

重点从RNAi的发现与淀粉品质相关的淀粉合成酶及其利用RNAi在提高直链淀粉含量、降低直链淀粉含量等品质改良研究方面进行了回顾并对其存在的问题作了初步探讨。

Adopt Fmoc solid-phase synthesis method to synthesize the linear peptide,and use DCC-HOBT method to cyclize the antamananide the result of study shows: the resulting that the linear peptide is 64%,the purity is 95%;the content of Antamananide is above 25% in the products.

采用Fmoc固相合成法合成直链多肽，并用DCC-HOBT环化法合成了抗鹅膏肽，结果表明：所得的直链多肽收率为64%，纯度为95%；所得的环化产品中抗鹅膏肽的含量在25%以上

In March, May and July, Cyanophyta was the dominant one, with high proportions of 45.6%, 55.9% and 87.7%, respectively, whereas the proportions for Bacillariophyta decreased to 30.1%, 25.9%, and 1.1%, respectively. In November, proportions for Bacillariophyta and Chlorophyta were equivalent, 40% each, and the Cyanophyta composed below 20%. In December, Bacillariophyta made up 25.6% and Cyanophyta 38.2%. In March, May and July, dominant species of Cyanophyta were Microcystis aeruginosa, Pseudoanabaena, and Gloeothece linearis. In dry January, November and December, species of Bacillariophyta were dominated by A chnanthes sp., Melosira ambigua, Melosira granulata and Cyclotella meneghiniana.

全年中，蓝藻与硅藻比例变化较大，二者呈相反的变化趋势。1月份硅藻占较高比例（63.1％），蓝藻较低（〈20％）；3、5、7月份蓝藻比例较高（分别为45.6％、55.9％、87.7％），而硅藻较低（30.1％、25.9％、1.1％）；11月份硅藻与绿藻比例相当（各占40％），蓝藻低于20％；12月份硅藻与蓝藻比例分别为25.6％与38.2％。3月份和丰水期浮游植物优势种主要为铜绿微囊藻、假鱼腥藻和线形粘杆藻等蓝藻种类，枯水期的1月、11月和12月主要以曲壳藻类、模糊直链藻、颗粒直链藻和梅尼小环藻等硅藻种类为优势种。
