乙基氰

OBJECTIVE: To study the synthesis of β-phenylethyl isocyanate.

目的：研究β-苯乙基异氰酸酯的合成。

Curing reactions of BPF/R EP system containing dicyandiamide were studied with differential scanning calorimetry,and the curing systems and curing condition were studied systematically with 2-ethyl-4-methyl imidazole(2E4MZ) accelerating dicyandiamide,which affected the property of BPF/resorcin copolymeriza.

通过差示扫描量热法研究了2-乙基-4-甲基咪唑对双氰胺-双酚F/间苯二酚共聚型环氧树脂体系固化反应的促进作用，并系统地探讨了固化体系及固化条件对固化物性能的影响。

FTIR,X-ray,TMA and SEM were used to study and characterize the microview struc-ture and thermoplasticity of cyanoethylated wood.

利用FTIR、X－ray、TMA、SEM等对氰乙基化木材的微观结构和热塑性进行了研究和表征。

Three series of segmented polyurethanes were synthesized, which are based on 4,4'-methylene-di, N-methyl diethanolamine and hydroxy terminated poly-butadiene, poly or poly.

本文讨论了以聚环氧乙烷、聚环氧丙烷以及聚丁二烯为软段，以4，4'-二异氰酸二苯甲烷和N，N-二羟乙基甲胺为硬段的链段型聚氨酯的合成。

The formation, texture and some properties of cyanoethyl cellulose/dimethyl aceta-mide mesomorphic solutions were studied.

本文利用Abbe折射仪，热台偏光显微镜，小角光散射等方法研究了氰乙基纤维素/二甲基乙酰胺液晶溶液的形成，形态结构和某些性质。

The results show that the curing agent, with 6% amount of epoxy weight, is a mesothermal latent curing agent, and curing temperature is about 120℃(1h).

采用双氰胺和2-乙基-4-甲基咪唑组成的体系作为固化剂体系，利用DSC分析了固化剂体系的最佳固化工艺。

According to the mass ratio of 5 to 1 between dicyandiamide and 2-ethyl-4-methyl imidazole, the curing system belongs to a mesothermal latent curing agent. The results show that curing products have good heat resisting property.

2所选用的固化剂体系由双氰胺和2-乙基-4-甲基咪唑组成，两者按5：1质量配比组成的体系属于中温潜伏型固化剂，环氧固化物具有良好的耐热性。

The Power: Phenethyl isothiocyanate, which, along with beta-carotene and vitamins C and E, may help keep cancer cells at bay.

健康因子：苯乙基异硫氰酸酯，与胡萝卜素和维生素C、E一起可助于抑制癌细胞于雏形。

Phenethyl isothiocyanate also has been shown that to induce cell cycle arrest and apoptosis in many human cancer cell lines, such as human non-small lung cancer cells, prostate cancer PC-3 cells (Prostate cancer metastasized to bone).

另外，也有文献指出苯乙基异硫氰酸酯会造成人类非小细胞肺癌和前列腺癌细胞(PC-3)的凋亡。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
