By addition of NaCl, EAI was increased at pH<3 but decreased at pH>3. As for ES, it was decreased by adding NaCl in the larger pH range (pH1-10). 在酸性区域(pH<3);添加NaCl提高了乳化活性;而在pH>3 的区域却降低了乳化活性。在较广pH值范围(pH1-10)内;添加NaCl降低了乳化的稳定性。
Zeta potential decreased from 38.6 mV to 23.7 mV over a pH range of 3.3 to 11.7 in the presence of 0.5 mmol/L CTAB and the average size of ink particles increased by 13 nm. pH对CTAB的作用效果有较大影响;当CTAB浓度为0.;5 mmol/L时;将体系pH从初始值3
This paper gives a new method to determine the F concentration in water solutions by means of the pH range of acidimeter. The method is simple, fast and decreases the errors. 本文给出一种用酸度计的pH档测定水溶液中F~-浓度的新方法,该法不仅简便、快速,而且减小了测量误差。
Each species has e ability to grow within a specific pH range, which may be broad or limited, with the most rapid growth occurring within a narrow optimum range. 每一种生物都具有在特定酸碱度范围内生长的能力，这个范围可能宽或窄，在一个窄小的最适范围内会有最快速的生长。
The flocculation reagent has many advantages: cheap, easily composed , posionous , low dosage and raw material easily got, applicable to wide PH range with high efficiency . 絮凝剂具有制作方法简单;无毒;用量少;原料来源广泛;适用pH值范围较宽以及絮凝效果好;药剂费用低等特点.
The adsorption of aflatoxin B 1 by modified montm orillonite was not affected by lysine at concentration of 2.0 mg/mL and 4.0 mg/m L,pH range from 2.0 to 8.0 and temperature changes. 赖氨酸含量为 2 .;0mg/mL和 4
The high-performance sorbent could adsorb more than 90% of phenoK 4-chlorophenoK 2,4-dichlorophenol and pentachlorophenol when the pH range was found to be 6.5-8.5,and the optimum mass of the sorbent was 8g/L. 在pH=6.;5-7
The main conclusions drawn from the study are as follows:Lit is unable to evaluate SSC of paddy soil with 1M HAc-NaAc(pH4) method directly within wide pH range, because some unavailable silicon for plant can be extracted from soil which pH value are high. 由于1M HAc-NaAc(pH 4)缓冲液酸度过强，用该法测定的土壤有效硅含量不能直接判断广泛pH范围的水稻土供硅能力。
That word is spelt with a PH, not an F. 那个字里的f音拼作PH而不是F。
