secondary carbon

The experiments included both small and extended test. Because the Arsenic in secondary zinc oxide exists mainly in the form of arsenous oxide, which is volatile, the roasting method of adding reductant carbon to secondary zinc oxide is used to remove Arsenic.

本研究实验包括小型实验和扩大实验，由于次氧化锌中砷主要以三氧化二砷形态存在，因此可以通过三氧化二砷易挥发特性，采用在次氧化锌中加入炭还原剂的焙烧方法脱砷。

For initiator B, when temperature is less than 180 ℃, MAH first reacts with secondary carbon of EB-block, secondly reacts with tertiary carbon; when temperature is higher than 180 ℃, the reaction rate of MAH reacted primary, secondary, tertiary carbon are similar.

对引发剂B，在温度低于180℃之前，仲碳原子最易发生接枝反应，其次是叔碳原子，当温度高于180℃后，伯碳原子、仲碳原子和叔碳原子的反应速率差不多。

The secondary particle sphere of xonotlite yielded by konilite is of hollow structure, however, for the carbon white fibrous crystal just stacked densely and balling up is poor.

由粉石英制备的硬硅钙石二次粒子球具有中空结构，而白炭黑对应样品则以纤维聚集成的块体为主，成球差。

The growing secondary and tertiary industries are the main reason of rapidly increasing energy consumption and carbon emissions.

第二、三产业能耗的不断增长是我国能源消费和碳排放增长的主要原因。
