查询词典 addition

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。

Supplementation SP or probiotics can increase the laying rate of hen,hen day egg production and mean egg weight,and decrease feed/egg ratio,whenas the addition of SS can not.③The addition of either SP or SS can increase liver IDⅠactivity and serum T_3,and decrease T_4 of hen.Especially when SP was supplemented,the liver IDⅠactivity and serum T_3 of hen increased and serum T_4 of hen decreased as supplemental So level increased.

添加SP或益生菌均可提高蛋鸡产蛋率、日产蛋量和平均蛋重，降低料蛋比；③添加SS或SP均能提高蛋鸡肝IDⅠ酶的活性和血清T_3水平，降低T_4水平，特别是添加SP时，随着硒添加水平的升高，蛋鸡肝脏IDⅠ酶的活性和血清T_3水平升高，血清T_4水平则降低；而添加益生菌对蛋鸡肝IDⅠ酶的活性没有显著影响，却能显著提高血清T_3水平，而降低T_4水平。

Result After addition of wood vinegar, the fermentation temperature of sawdust was obviously increased, and the highest temperature reached 67.0℃,being 3.5℃ higher than that of CK, and the days when fermentation temperature was above 55℃ reached 57 d, being 40 d more than that of CK.
