分散性

The results show that the surfactant species impact apparently on the purity, dispersion degree and particle size of the reducing sample. The non-ion surfactants can improve the dissemination of ultrafine silver particles, but both the dispersive effects of cation and anion surfactants are unapparent.

结果表明：表面活性剂的种类对制备样品的纯度、分散性和颗粒大小有着重要的影响，其中阳离子表面活性剂和阴离子表面活性剂的分散效果不明显，非离子表面活性剂的分散效果最好。

The microstructure and morphology are examined by SEM, XRD, EPMA, and the electrochemical performance is studied by potentiodynamic polarization and current efficiency. The results show that the alloy elements in the electrode coating prepared by the sol-gel process are well distributed, more sufficient to form solid solution and with higher current efficiency than by the traditional thermal decomposition process. The deactivation effect is due to the forming of unconductive TiO2 for the sol-gel process, but due to the dissolution of active composition for the thermal decomposition process.

SEM、XRD、电子探针、极化曲线、电流效率实验表明，由溶胶-凝胶法制备的氧化物涂层比热分解法制备的氧化物涂层的分散性好、形成固溶体充分、电流效率高；由溶胶-凝胶法制备的氧化物涂层的失效是由于生成不导电的TiO2引起，而由热分解法制备的氧化物涂层的失效是由于活性氧化物涂层的溶解引起。

The results show that wet air reduces both fatigue life and strength with the influence-factor of 0.6059 and 0.8722, respectively. Wet air environment enlarges the dispersivity of fatigue life, therefore using the corrosion-influence-factor obtained by eigenvalue or mean value to predict the fatigue life with high reliability will cause an unconservative conclusion.

结果表明，潮湿空气环境显著降低了2024-T3铝合金的疲劳性能，潮湿空气环境对其疲劳寿命特征值和疲劳强度均值的影响系数分别为0.6059和0.8722；在潮湿空气环境中疲劳寿命的分散性变大，用疲劳寿命的中值或特征值得到的腐蚀影响系数进行可靠度95%的腐蚀环境下的寿命修正，将得到偏危险的结果。

In view of the polydispersity and unhomogeneous molecular weight of soda lignin in pulping black liquor, the method which firstly classify lignin then react in homogeneous system has been adopted for a long-term to chemically modify the soda lignin, in order to improve the integral performance of lignin technical products effectively. However, there are following drawbacks in this technology: the low ultilization of lignin, and difficult seperation from the reaction system.

鉴于制浆黑液中的碱木素具有多分散性较大、分子不均一的特点，为有效提高技术木素产品的整体性能，长期以来采用先级分木素、后在均相体系中反应的方法，对碱木素进行化学改性，但此法存在木素利用率低产品难从反应相中分出的缺陷。

And the polycarboxylate based superplasticizer prepared by the macromer under optimal condition has good plasticizing and fluidity-retaining ability, the initial fluidity of cement paste reaches 303 mm, and the fluidity after 1 h is 297 mm.

The experimental research results of mortar indicate that admixing and permeating shrinkage reducing agent can all reduce its dry shrinkage and self dry shrinkage effectively.

砂浆试验研究结果表明：减缩剂的内掺和渗透法均能有效减少砂浆的干缩和自干燥收缩：减缩剂的掺入可提高水泥粒子的分散性，改善砂浆的工作性能，但使砂浆的3d、7d抗压强度稍有降低，对28d抗压强度影响不大。

While equal amount of MgSO4 was added ,bulks occurred in 5 hours.

微球的粒径在6h后趋于稳定，多分散性相应提高。

Research results indicate that X FLOUR has notable effects of fluidizing and water reducing.

研究结果表明：X粉具有显著的流化与减水效应，其流化与减水效果与目前市售掺合料的最高水平相当，明显好于硅灰。X粉与硅灰复合后，仍具有流化效应。X粉产生流化效应的机理，一是增加水泥浆悬浮体系的分散性；二是通过填充效应减少填隙水，增加了用于混凝土流动性的水量；三是增加混凝土混合料的浆体体积。X粉流化与减水效应的发挥，以与高效减水剂双掺为前提。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
