active alkali

There is the worst point between the active alkali aggregate and inactive aggregate in the concrete ASR .

在混凝土碱硅酸反应中，活性碱骨料与非活性骨料之间的比值存在最劣点。

For early age concrete , the ratio between the active alkali aggregate and inactive aggregate haves an impact on concrete ASR .

因此，对于早龄期混凝土，活性碱骨料与非活性骨料之间的比例大小影响混凝土碱硅酸反应。

The basic density of the wood influenced the dosage of active alkali and pulp yield only to some extent .

而基本密度只是在一定程度上影响着用碱量和得率，但不是影响制浆特性的决定因素。

Active Ingredients of Kaolin Alkali Roasting Clinkers , Structure & Morphology of the 4A Molecular Sieves Synthesized

高岭土碱焙烧熟料活性组份及所合成的4A沸石结构与形态

Specific surface area and iodonium adsorbance of active carbon increase with alkali / carbon increasing , but high alkali / carbon leads to mesopore proportion increasing ;

活性炭比表面积及碘吸附值随碱/炭（即碱的添加量）的增加而增加，但高的碱/炭将增大中孔比例；

The content of carboxyl reduced 53.41 % and the total acidic group had little changes ; the phenyl structure of lignin was steady . The active functional group of alkali lignin was increased so that the reactive activity was enhanced .

甲氧基含量降低了1773%，羧基含量降低了5341%，总酸性基变化不大，木质素的苯环结构稳定，活性官能团增加，反应活性提高，Pd/C催化剂对木质素还原活化反应具有良好的催化作用。
