New Zealand researchers to experiment in mice fed a garlic called diallyl disulfide material, resulting in significant anti-cancer effect.

新西兰的研究人员给实验用鼠喂入了大蒜内一种叫二硫化二烯丙基的物质，结果有明显的抗癌作用。

Objective: To investigate the arrest effect of diallyl disulfide in the cell cycle of human nasopharyngeal carcinoma CNE2 cell line and its molecular mechanism.

目的：在前期工作的检测上，进一步探讨二烯丙基二硫(diallyl disulfide， DADS)对人鼻咽癌CNE2细胞周期的阻滞作用，并研究组蛋白乙酰化状态及其调控p21WAF1蛋白表达改变的情况。

Unsaturated polyester crosslinked by styrene has poor toughness. In this paper, diallyl phthalate was used as co-crosslinking agent with styrene for toughening UP.

针对苯乙烯固化的不饱和聚酯韧性差的问题，研究采用了适用于高温固化的邻苯二甲酸二烯丙酯作为不饱和聚酯的共交联剂。

Objective:To study the proliferation and expression of survivin protein in human leukemia HL-60 cell line treated with diallyl disulfide and to thus investigate the mechanism of DADS to inhibit HL-60 cells' growth.

目的：观察二烯丙基二硫(diallyl disulfide，DADS)作用于人白血病HL-60细胞株后，细胞增殖及survivin蛋白表达的变化，探讨DADS对HL-60细胞增殖的影响及其机制。

Diallyl disulphide was identified in these three cultures, which is a representative matter in volatile of garlic and has antimicrobial activity. So this matter is concluded one of the allelochemicals.

同时在这3种栽培方式中均检测到了二烯丙基二硫化物，这种物质是大蒜挥发油中典型的物质，且具有良好的杀菌作用，因此认为大蒜根系分泌也能释放这种物质。

AIM: To investigate the change of cell cycle checkpoint kinases Chk1/2 in human gastric cancer MGC803 cells induced by diallyl disulfide. METHODS: mRNA expression was assayed by means of RT-PCR in MGC803 cells treated with DADS.

目的：观察二烯丙基二硫化物对人胃癌MGC803细胞的细胞周期检查点激酶1(Chk1)和细胞周期检查点激酶2(Chk2)的影响。

The leftover from bamboo processing was comminuted into bamboo fine powder, which was surface-treaded with a coupling agent of ethenyl tri (β-methoxyethoxy) silane; and then in the presence of initiator dicumyl peroxide, the powder was compounded with styrene-isoprene block copolymer/bromobutyl rubber blend to prepare a crosslinked vibration-absorbing rubber composite material.

将竹加工的边角料粉碎并用乙烯基三硅烷偶联剂处理，再与苯乙烯－异戊二烯嵌段共聚物和溴化丁基橡胶的共混物进行复合，在过氧化二异丙苯引发剂的作用下制得交联型橡胶吸振复合材料。

烯类与丙二酸二乙酯的加成反应

In this study aldylencdithiomethylene Malonic acid acts as the main coordination agents and compound iron ion have been synthesized by the means of solution, As a result ,the 1D polymer is obtained.

本论文采用常规的溶液合成方法，首先设计合成了一个以含有二硫缩烯酮结构的丙二酸类配体和过渡金属铁离子的单核配合物，再以此单核配合物作为配体设计合成了三个异多核配合物和配位聚合物。

The result indicated that polychloride and anionic polyacrylamide could improve the retention of TiO_(2)-zeolite singnificantly.

考察了TiO2-沸石复合纸板制备中聚二甲基二烯丙基氯化铵/阴离子聚丙烯酰胺和阳离子淀粉/APAM二元助留体系助留效果。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
