lene

Propy - lene and butylene yields increase with low hydrogen transfer reaction .

氢转移反应越低，丙烯及丁烯等烯烃选择性越高。

The polyphenol oxidase activity and phenolics content can be induced by the lene .

乙烯利处理提高了果实多酚氧化酶活性及酚类物质的含量。

Who want it with lene ?

谁想找琳的麻烦？

In addition , a propylene purification process and a low-pressure propy - lene recovery unit , are adopted along with the use of N-type catalyst .

在使用N型高效催化剂时还采用了与北京化工研究院合作开发的丙烯精制和低压丙烯回收的配套技术，取得了良好效果。

Effects of the variations in loading levels of silica , acety lene black , dicumyl peroxide and ferric oxide on the conductivity and mechanical properties of silicone rubber was studied by orthogonal testing design .

通过改变白炭黑、乙炔炭黑、过氧化二异丙苯和氧化铁的用量，以正交实验设计法对硅橡胶的导电性以及综合性能加以研究。

During the revamping and expansion of ethy - lene plant in the Olefin Plant of PetroChina Liaoyang Petrochemical Company in 2001 , new technology was adopted to revamp the G_2 hydrogenation system , and the former C_2 gas-phase selective hydrogenation catalyst was replaced by BC-H-20B catalyst .

中国石油辽阳石化公司烯烃厂在2001年乙烯装置改扩建中，采用新工艺对碳二加氢系统进行了改造，并将原碳二气相选择加氢催化剂更换为BC-H-20B型。
