实验发现,亚硝酸盐、重氮化合物、2萘胺1磺酸对苯胺有很强的干扰。
蒸馏是去除重氮化合物、2萘胺1磺酸干扰的有效方法。
1·Phyllostachys shoot grown from seed were sprayed by lanthanon multiple fertilization, naphthalin acetic acid, GGR and KH_2PO_4 with random group sample method.
采用随机区组设计方法,对毛竹实生幼苗喷施稀土多元复合肥、萘乙酸、GGR和复混磷酸二氢钾。
2·Serials of naphthalin and tripolycyanamide have low water reducing efficiency, bad flow degree under low water cement ratio and sharp loss of concrete slump.
萘系与三聚氰胺系减水率较低,在低水灰比下流动性较差且坍落度损失较大,不利于商品混凝土的运输和施工。
