1：橄榄油，40年前，来至7个国家的研究所报告指出单不饱和的：橄榄油里含有只含一个双键或三键的化合物，尤指脂肪酸(如油酸具有很大减低心脏病和癌症的患病率。

Increased. In addition, the life of light can also make the blood of unsaturated fatty acid double bond or triple bond was cut, and saturated fatty acids is not easy to be oxidized lipid , a decrease of intravascular lipid deposition, so that the vessel wall smooth, thus reducing atherosclerosis, cataracts, such as cardiovascular disease or the occurrence of eye disease, health promotion plays a good efficacy.

此外，生命光线还可以使血液中不饱和脂肪酸的二重键或三重键被切断，饱和脂肪酸不容易再被氧化成血脂，减少了血管内脂质的沉积，使血管壁光滑，从而减少动脉硬化、白内障等心血管疾病或眼科疾病的发生，对人体健康起着良好的促进功效。

The synthesis and properties of metal-carbyne complexes is always a hot topic in the research field of organometallic chemistry since the first synthesis of transition metal complexes with a formal metal-carbon triple bond reported by E.O.
