从图5还可以看出，aeo一7不仅差溶液编制的zeta电位有较不小的感化，而且差炭暗粒子堆积的感化水平澄辉不小于ctab、sds和capo。

The analyses of XRD,Zeta potential,SEM,EDS and low voltage cathodoluminescence were conducted for investigating the crystal structure,potential,morphology and luminescence properties of coated and uncoated Y_2O_3∶Eu.

通过XRD，Zeta电位，SEM及低压光谱分析等检测手段分析了包膜前后Y2O3∶Eu的晶体结构、电位、形貌与发光性能，探索了包膜工艺。

As noted by the National Hurricane Center, Zeta, the final tropical storm in the Atlantic this season, was itself a record breaker: forming in late December, Zeta was both the longest-lived tropical storm to cross into the New Year, and the longest-lived tropical cyclone in January. See the NCDC and GISS analyses, the NOAA press release from December, and the NHC's discussion about Zeta .

根据国家飓风中心报告，大西洋的最后一个热带风暴Zeta也是一个记录刷新者：在9月下旬形成的Zeta，是持续最长的热带风暴，一直持续到新年；也是一月份持续时间最长的龙卷风。

The dispersion mechanism of the dispersants was analyzed by testing the Zeta potential of the dispersion phase in the dispersion medium. It was shown that Ⅰ and Ⅱ raised obviously the absolute values of surface Zeta potential of titania particles, and NK-1 formed good solvate layers of the particles so that the nano-titania particles were stably dispersed in the water solns.

The Zetasizer Nano ZS is made in Marvern in England. It is the newest Zetasizer Nano ZS with the newest technology. Malvern Zetasizer Nano ZS90 is for the measurement of size, zeta potential of dispersed particles and the molecular weight of random coiled polymers. If it connect with the Autotitrator, it can measure zeta potential as a function of pH, conductivity or concentration of an additive, provides much greater insight into the processes involved in stabilizing or flocculating disperse systems.

英国马尔文公司生产的Zetasizer Nano ZS型纳米粒度仪是目前世界上技术最先进的纳米粒度仪之一，该仪器可以测定纳米材料的粒度分布、ZETA电位值，并可以进行蛋白质的熔点测定，及蛋白质等大分子和聚合物材料的分子量测试，如果与自动滴定仪相连接后，可自动测定粒度或Zeta电位随pH值、盐浓度或添加剂浓度等的变化趋势。

Zeta potential,density of surface carboxyl groups,the interaction between carboxyl groups and component in copolymerization emulsion,mechanical properties of films,state of water,particle diameter and distribution of particle diameter and theological behavior of emulsion were investigated by Zeta meter,the conductometric titration, particle size apparatus,dynamic mechanics analysis,differential scanning calorimmetry,scanning electron microscope,rheological apparatus,respectively, to study the mechanism on the water resistance of modified PVAc emulsion.

利用Zeta电位仪、电导滴定法、激光粒度仪、DMA、DSC、SEM、流变仪等手段从Zeta电位、表面羧基密度、羧基和乳液组分中的相互作用、羧酸改性后胶膜的力学性能、水的存在状态、粒径分布、流变性能和微观形貌方面探索了羧基提高乳液耐水性的机理。

Synthetic ettringite precipitated from solution shows a highly positive zeta potential, hence it adsorbs great amount of negatively charged superplasticizer. Monosulfate has only a slightly positive zeta potential and adsorbs smaller amounts of superplasticizer. For syngenite, portlandite and gypsum, the zeta potential is around zero or negative.
