Such a viewpoint of the effects of a little water addition has never been reported, it opened a new way to product SWCNTs with high purity and low cost. On the ground of the experimental results and mechanism studies, a little water addition may open a way for using the natural gas as carbon source to manufacture SWCNTs. By analyzing XRD, XPS results and with comparative experiments, we concluded that the active phases of SWCNTs growth in Ar were small Fe particles. A little W species can improve the surface characters of support and increase the dispersion of Fe particles, but higher W loading will cause large quantity of WC, which decompose CH〓 to amorphous carbon.

本文根据W-Fe-MgO催化剂中间产物和粗产物的XRD、XPS测量结果，结合制备实验和对比实验指出：在Ar中1073K下，生长SWCNTs的活性相是Fe的小颗粒，少量W在催化剂中以氧化物形式对载体表面改性，起提高Fe分散度的作用，但W浓度过高时在反应过程中会生成大量WC，又会催化CH〓分解为无定形碳，造成产物中SWCNTs含量下降。

When enabled, sounds in zh, sh, and ch can be represented by z, s, h.

当启用时，声音在汉语和SH ，和CH可以代表用Z ，硫，每小时

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。

The Latin word ancora itself came from Greek ankura but was sometimes spelled anchora in Latin because of a false analogy with other Greek words, in which the sound was spelled ch.

拉丁词ancora 来自希腊语中的 ankura ，但有时拼写成anchora 是因为同其它希腊词进行了错误的比较，在希腊语中发k的音都拼写成ch 。

A series of antimony mercaptide compounds which formula are Sb 〓 and Sb S (CH〓〓COOR 〓(R represents an alkyl or aryl, aralkyl, n=0～2) have been synthesized. A new synthetic method has been invented to solve the defect of abroad patent method which has complex technological conditions and singleness intermediate compounds. A new catalyst QL-1 and preactivated antimony trioxide and other means have been used to avoid neutralizing, washing, separating and other procedures of intermediate and simplifing process flow at the same time. According to this new technique, a series of antimony mercaptides and their intermediate products have been synthesized with high yield.

合成了结构为SbS(CH〓〓COOR〓及Sb〓（R为烃基或芳烷基，n=0～2）的一系列硫醇锑化合物，针对国外专利报道的合成工艺存在着工艺条件苛刻，同时需多步完成，操作复杂，而且中间体品种单一的缺陷，发明了一种一步法合成硫醇锑化合物的新工艺，采用QL-1催化剂，且将三氧化二锑预先活化，变固—液相反应为液—液相反应，同时可免除中间体的中和、洗涤、分离等工序，工艺流程简化，产品收率高，且能制得系列硫醇锑产品。
