Besides, benzyl isothiocyanate and phenethyl isothiocyanate increased caspase-3 activity. Therefore, benzyl isothiocyanate and phenethyl isothiocyanate induce apoptosis in human prostate cancer DU-145 cells.

由此可知，苯甲基异硫氰酸酯和苯乙基异硫氰酸酯会造成人类前列腺癌细胞株DU-145走向凋亡的命运，值得更进一步研究发展为抗癌药物。

The volatile components were separated and identified using GC-MS technique. RESULTS Seven ingredients were. isolated: 2-ethyl-hexyl-adipate (66.5%), 1-methoxy-4-(1-propenyl)benzene (12.5%), isopropyl isothiocyanate (6%), isobutylisothiocyanate (6%), 6-methyl-5-heptene-2-one (3.5%), benzaldehyde (1.4%), phenylacetaldehyde (0.8%).

结果 分离出7个成分，采用峰面积归一化法确定了各成分的相对含量，分别为66.5%双－2-乙基己基－己二酸、12.5%1-甲氧基－4-（1-丙烯基）苯、6%异硫氰酸异丙酯6%、6%异硫氰酸异丁酯、3.5%6-甲基－5-庚烯－2-酮、1.4%苯甲醛、0.8%苯乙醛。

Most phototropic organisms are autotrophic (i.e.show photoautotrophism);these comprise the green plants,Cyanobacteria,and some photosynthetic bacteria(the purple and green sulfur–bacteria ).

大多数光合成生物是自养的，这包括绿色植物、蓝细菌以及一些光合细菌（紫色硫细菌和绿色硫细菌）。

Previous studies indicate two possibilities of the formation of the greigite: 1 the seepage of seawater during the postglacial transgression provides sulfate and makes the reducing diagenetic conditions; 2 it may be precipitated as the authengenic mineral in marine or lacustrine sediments during the low sea-level stand of the Late Pleistocene.

本研究在前期工作基础上，针对已发现的硫复铁矿富集区选择典型柱状样6根(深约1.5-2.5m，长柱样；B436、B437、B439、B459、B483、B484)，同时于扬子浅滩前缘新获取柱状样4根(深约0.3-0.5m，短柱样；ST9、ST13、ST15、ST23)，进行了U系测年，粒度分析、磁性测量、X—射线衍射分析、微体古生物鉴定分析、粘土矿物和化学元素含量测试，试图揭示东海外陆架浅部地层结构、揭露硫复铁矿在地层中的分布规律及成因机制，从而探讨该区晚更新世以来海平面波动模式及其控制下的地层发育。

The beta-thioalkoxyalcohols could be obtained in good yields by the reaction of dialkyl-substituted propargylic dithioacetals with a series of carbonyl compounds.

其结果对研究煤燃烧过程中硫的析出规律及燃中固硫有一定帮助。

The results show that the levels of the total sulfur and pyritic sulfur vary little in different size grades of coal, but in a same size grade the sulfur content increases with the density grades.

结果显示，全硫和黄铁矿硫在各粒度级煤中分布较均匀，其含量在各密度级煤中的分布随密度级的增大而增大。

The high sulfur coal from Jiexiu in Shanxi is used in this experiment and the influence of removing pyritic sulfur by adding different pyrites depressors on the process of agglomeration was explored in this study,The experiment result shows that adding pyrites depressors on the process of oil agglomeration can improve the sulfur-removing rate.

油团聚是以脱除煤中灰分为主的团聚技术，脱硫的效率很低，采用山西介休的高硫煤，探索在油团聚过程中加入不同的黄铁矿抑制剂(巯基乙酸、重铬酸钾、高锰酸钾)对脱除煤中黄铁矿硫的影响。结果表明加入黄铁矿抑制剂对脱硫效率有一定程度的影响

It was observed in the Cr-Ni-Mo steels that the intergranular ductile fracture is caused by the reprecipitation of MnS particles in the steel with ordinary S content, and the overheating is also performed by the repreeipitation of AlN or VC particles along the prior austenite grain boundaries in one containing low S. Thus, a proposal seems to be made that the mechanism of overheating of Cr-Ni-Mo steels is related to the solution and reprecipitation of MnS, AlN or VC particles along the prior austenite grain boundaries.

MnS粒子的重新析出使普通硫含量的Cr-Ni-Mo钢发生沿晶延性破断，而AlN或VC粒子在高温奥氏体晶界的重新析出也能使低硫的Cr-Ni-Mo钢过热。
