alkane

1.a radioactive decay series; the paraffin alkane series.

放射性蜕变的；链烷烃

2.and for nitroethane there were nitroficating low carbon alkane, chloroethane, and diethyl sulfate;

1基烷用烷化法;

3.and master conformation of alkanes, isomerism, cis-trans isomerism and enantiomorphism;

烷烃构象、同分异构、顺反异构对映异构现象；

4.Recent-year studies demonstrate that wax consists of not only high-molecular-weight normal alkane, hut also isoalkane, naphthene and olefin;

并认为蜡不仅仅源于高等植物，低等水生生物湖相藻类对蜡也是重要贡献者。

5.Carbon distribution and content of normal alkane and isoalkane in rubber waxes are measured by using high temperature gas chromatography.

用高温气相色谱法测定橡胶防护蜡中的正构烷烃非正构烷烃的碳数及含量。

6.It has been demonstrated that the methods are successfully used for QSRR studies of quinazoline derivatives, alkypyridine, haloid alkane, ketone, alcohol, sulfur alcohol compounds.

此方法中各参数物理意义明确，计算简便。
