Article 7 According to Article 18 of this law "the production of fissionable material from nuclear reactors" means plutonium, U-233 and any other material which is designated by the Executive Yuan as fissionable material.

第7条 本法第十八条所称核子反应器所生产之可分裂物质，系指钸、铀－二三三及其他经行政院所指定之可分裂物质。

The results showed that diploid and tetraploid had higher root activity, flagleaf soluble protein content, SOD and CAT activity before anthesis. However, the rootactivity, flag leaf soluble protein content, SOD and CAT activity of diploid and tetraploiddeclined more quickly and became lower than those of hexaploid species from 15 days afteranthesis. While MDA content increased more quickly and became higher than those ofhexaploid species from 5 days after anthesis. Correlation analysis showed that delaying the flag leaf senescence can promoted transfer of nitrogen and dry matter, increasedaccumulation of nitrogen and dry matter after anthesis, enhanced grain and protein yield.

结果表明，与普通小麦和小黑麦相比，二倍体和四倍体材料开花以前具有比较高的根系活力、可溶性蛋白含量、SOD和CAT活性；开花以后，根系活力、旗叶可溶性蛋白含量、SOD和CAT活性快速下降，MDA含量快速上升，衰老加快；相关分析表明，延缓小麦旗叶衰老进程，可以促进花后氮素和干物质运转，增加花后氮素和干物质积累，提高籽粒产量和籽粒氮素积累量。

Onions contain a product called "Oak leather flavin" chemical substances, is now known to one of the best natural anti-cancer substances.

洋葱中含有一种名为"栎皮黄素"的化学物质，是目前已知最佳天然抗癌物质之一。

The polysilicic acid is compounded with polyferric chloride sulphate under certain conditions, then the polysilicic acid-polyferric chloride sulphate flocculence is prepared. The study shows that: when the Cl-/SO42-molar rate is 1:1, the Fe/Si molar rate is 2:1, the flocculence has the best effect on paper-making waste water treatment.

将聚硅酸与聚合硫酸氯化铁在一定条件下复合，制备聚硅酸聚合硫酸氯化铁复合型絮凝剂，研究表明：在氯根与硫酸根物质的量比为1：1，且铁与硅物质的量比为2：1时，制得的复合型絮凝剂对造纸废水具有最佳处理效果。

The motions of this visible material reveal that it is mere flotsam on an unseen sea of unknown material.

从这类可见物质的运动显示，它们只不过像是在未知物质组成的不可见海洋上飘流的残骸。

After analyzing the data, the author concluded that materials were great correlative to behaviors of children. And the author considered that materials' character, function, fluidness, number, kind influenced the behaviors of children.

通过对资料的分析，研究者认为，物质材料与幼儿角色行为之间存在着密切的关系：物质材料的属性、功能、流动性、数量、种类等影响幼儿的角色行为。

Those listed by UNESCO represent only a small fraction of China's numerous forms of folk art. An ancient civilization with a history of over 5,000 years enjoying cultural diversity created by its 56 ethnic groups, China boasts a wide variety of intangible cultural heritage. It released its first national intangible cultural heritage list in May 2006, incorporating 518 entries.

相对于中国浩如烟海般散落在民间的文化艺术来说，入选UNESCO的这几项只不过是沧海一束。5000多年文明史、56个民族多元文化生态，造就了中国多姿多彩的非物质文化遗产。2006年5月，中国公布了第一批国家级非物质文化遗产名录共518项。

Eduardo Giannetti da Fonseca, one of Brazil's most distinguished economists, describes members of the middle class as "people who are not resigned to a life of poverty, who are prepared to make sacrifices to create a better life for themselves but who have not started with life's material problems solved because they have material assets to make their lives easy."

Eduardo Giannetti da Fonseca是这样描述中产阶级的："他们不甘于贫穷的生活，他们愿意努力为自己创造更好的生活，但是他们又不需要从解决物质基础开始，因为他们已经有了让生活更舒适的物质基础。"

The toxic compound was traced by lettuce germination test guided fractionation and HPLC purification, and was identified as 3β-formyl usolic acid on the basis of 1H and 13C NMR experiments. It is the first time to find this compound from the order of Myrtaceae

用高效液相色谱对桉树凋落叶中毒性物质进行分离、纯化，以小麦、绿豆、大速生菜为指示植物，对分离到的物质进行毒性跟踪，分离到一个毒性较强的组分，经1H氢谱和NMR鉴定为3–β甲酰基–乌索酸。

The X-ray diffract was used to analyze the crystal structure of the composite. Results show that after the talc was treated with blend coupling agent, the crystal structure of talc changed, and effect Intercalation phenomenon.
