1.Group IV: Polyalphaolefins (PAO's) are made by combining 2 to more decene molecules into an oligomer, a short-chain-length polymer.
第四组：聚（包）的是由结合2更癸分子成低聚物，短长链聚合物。
2.The 1-decene developed has great significance with the increasing of need to synthetic lubricant oil in . . .
随着国内对合成润滑油需求量的增加，开发生产1-癸烯具有重要意义。
3.Peak of decene is the highest in the chromatogram. Another compounds are detected such as pyrrole, furanmethanol, indole and guanosine .
组分含量最多的是十碳烯烃，同时还检出了一些含氮化合物吡咯、呋喃、吲哚、鸟甙等。
