Gongye shui chuli, 2004 研究了循环水中锌离子的稳定性，讨论了磺酸盐共聚物和水质因素对锌离子稳定性的影响。结果表明，随着磺酸盐共聚物ZF322浓度的增大，循环水中锌离子的稳定性增强;三价铁离子、钙离子浓度和碱度的增加都会降低锌离子的稳定性;正磷在低浓度时可增强其稳定性;pH值对锌离子稳定性影响很大，但加入药剂后影响比较小。

‘Tempo é dinheiro’: Usabilidade é Produtividade
Revista Espaço Acadêmico, 2012 Benjamin Franklin foi um intelectual de sua época (1706-1790) e uma frase marcante dele que ultrapassa fronteiras é “Remember that time is money”. Lembre-se do que já disse: Tempo é o bem mais precioso que todo ser humano pode possuir, inclusive para aqueles que pensam nada ter.
