The results showed that compared with traditional fluorite and phosphorous slag, phosphorous slag composite mineralizer was effective on reducing amount of f-CaO in cement clinker and improving burnablity of raw meals, but the effect was still obvious when sintering temperature and sintering time were increasing. The analysis of XRD, SEM and petrographic structure showed that phosphorous slag composite mineralizer decreased viscosity of liquid, promotes the formation of Alite in clinker and improves crystal form and size of minerals.

结果表明，与传统的萤石和磷渣矿化剂相比，磷渣与萤石复合的矿化剂可有效降低水泥熟料中游离氧化钙的含量，改善生料的易烧性；在燃烧温度与时间增加的情况下，改善作用仍然明显；通过XRD、SEM与岩相结构分析表明，磷渣与萤石的复合矿化剂降低了液相的粘度，促进了A矿的生长，对矿物的结晶形态有改善作用，有利于晶体尺寸的生长发育。

HCo 〓-catalyzed hydroformylation and isomerization of allene and propyne Allene hydroformylation favors the linear anti-Markovnikov product in high regioselectivity both kinetically and thermodynamically. The origin of this regioselectivity comes from the enhanced stability of the η〓-allylic intermediate (η〓-CH〓CHCH〓 Co 〓.

HCo〓催化的丙二烯和丙炔氢甲酰化反应及异构化反应 HCo〓催化丙二烯氢甲酰化反应的区域选择性主要由不可逆的丙二烯插入步骤决定，动力学和热力学因素都有利于形成anti-Markovnikov中间物种(η〓-CH〓CHCH〓)Co〓，形成Markovnikov中间物种Co〓是不具有竞争性的。
