This paper thermodynamically and dynamically deals with the effects of pH-controlling agents of acetic acid, sodium and acetate, penetrating agent SZ-801 and temperature on low temperature dyeing of silk fabric with acid dyes. It has been verified that low-temperature dyeing is feasible. 本文从染色动力学和染色热力学方面研究了pH调节剂醋酸-醋酸钠、渗透剂SZ-801和温度对蚕丝织物酸性染料低温染色的影响,论证了低温染色的可行性。
In the culture condition when malic acid was used as carbon source, the strain took more phosphorus than that sodium acetate was used as carbon source. 该菌体经预培养转入富磷培养基后,碳源不同其摄磷能力有所差异:以苹果酸为碳源时的摄磷量略大于以乙酸钠为碳源时的摄磷量。
By this method, the Na+ ion and the precipitator sodium uranium zinc acetate reacts under the acid conditions to form sodium uranium zinc acetate to determine the Na+ contents. 藉在酸性条件下Na~+和沉淀剂醋酸铀酰锌反应,生成醋酸铀酰锌钠来测定Na~+含量。
Then regarding the mixed poly-carboxylic acid solution as the finishing agent, we discuss the effect of the phosphorus activators and non-phosphorus ones. Mixed activator ( citrate sodium, oxalic sodium and acetate sodium) is optimized after analyzing the different capabilities of the treated fabric. 然后以此混合多元羧酸为整理剂,探讨了含磷和无磷的混合催化剂对整理效果的影响,分析整理后织物的各项性能,优选出混合催化剂为柠檬酸钠、草酸钠和乙酸钠。
The effect of phenylalanine, abscisic acid, sliver nitrate, sodium benzoate, sodium acetate, chitosan and glycine on taxol production was evaluated by using a fractional factorial design. The major factors were proved to be chitosan, sliver nitrate and abscisic acid. 首先,用部分因素实验对苯丙氨酸、脱落酸、硝酸银、苯甲酸钠、醋酸钠、壳聚糖、甘氨酸对紫杉醇含量的影响进行评价,并找出其中主要影响因子壳聚糖、硝酸银和脱落酸;
Were the source of materials and co-market prices, acetic acid, acetic acid and sodium acetate and a combination of Na2CO3 is the most prospects for the development of desulfurization additives. 综合材料来源及市场价格,乙酸、乙酸钠及乙酸与Na2CO3的组合是最具有开发前景的脱硫添加剂。
The effect of the ratio of citric acid and the lactic acid, the concentration of sodium acetate and plating time on plating rate has been investigated by using the orthogonal test. 采用正交实验研究了柠檬酸和乳酸的比例、缓冲剂乙酸钠浓度及施镀时间对沉积速率的影响。
