查询词典 particles

Sheet-like particles are mainly aluminosilicates and calcium compounds on which iron compounds are attached, and the majority of floccule particles contain calcium compounds.

片状颗粒主要是附有铁化合物的铝硅酸盐和钙盐，絮状颗粒则主要含钙化合物。c不同采样点单个颗粒的形貌、组分有明显差异。

Congregation obtained after chitosan k and a treatments showed more tightness than sediments obtained without chitosan treatment, sediments after chitosan b and c treatments were network in structure. Mixed systems of pectin, protein and polyphenol were applied for studying a simulated system of kiwifruit juice. It was shown that the aggregates of pectin molecules in pectin solution were dispersing tubular globules. Particles in mixed solution of pectin and bovine serum albumin had two states: one was circular in photo, the other contained single particle or aggregates of several particles. Pectin decreased the interaction between protein and polyphenol and strengthened the stability of mixed solution of pectin, protein and polyphenol. Chitosan flocculated mixed solution of pectin, protein and polyphenol, and the floccule was white, having a network structure.

用果胶-蛋白质-丹宁酸混合体系作为猕猴桃原果汁的模拟体系研究结果表明：1、果胶溶液中果胶分子聚集物呈中空球形均匀分散；2、果胶／牛血清白蛋白混合溶液中的球形粒子有两种：粒子中央光线可透过，照片上呈环形；粒子的中央包含有单个或多个球形粒子的聚集体，认为粒子的中央是蛋白质，外层是果胶；3、果胶的存在抑制或减弱了蛋白质-丹宁酸之间的相互作用，果胶起到防止蛋白质-多酚产生沉淀的作用，增强了溶液的稳定性；4、壳聚糖加入果胶-蛋白质-丹宁酸混合溶液中时，可以絮凝果胶-蛋白质-丹宁酸混合溶液，溶液中出现白色的网状絮凝物。

The method takes amorphous silica as silicon source and by the steps of soaking, baking, Fe nano particles is implanted, amorphous silica implanted into Fe nano particles and Alpha germanium oxide are mixed and grinded, the obtained mixture is gas-solid treated by organic amine, so as to obtain the silicon germanium oxide composite nano line.

该方法是以无定型氧化硅作为硅源，通过浸泡、焙烧植入铁纳米粒子，再将植入铁纳米粒子的无定型氧化硅和α氧化锗混和研磨，通过有机胺的气-固相处理，最终获得硅锗氧化物复合纳米线。

The model results show that the hail embryos are mainly graupel particles.Solid phase precipitation accounts for 46% of ground precipitation amount and graupel-fall is 65% of solid phase precipitation.Graupel particles grow by accretion with rainwater and cloud water.Accumulation zone of supercooled water...

结果表明：玛曲冰雹云中冰雹胚胎以霰胚为主；在地面降水中，固态降水占降水总量的46%，而霰占固态降水的65%，霰主要靠撞冻雨水和云水增长；雹云中存在较弱的过冷雨水累积带，累积带的维持时间也很短，累积带中的过冷雨水有利于雹块的增长，但不起主要作用；雹块的增长主要是通过雹撞冻云水，其次是撞冻雨水增长。

The result showed that the one-valence cationsaccelerate the hydration process of α-hemihydrate gypsum greatly because they improvethe dispersed degree of α-hemihydrate gypsum particles due to the remarkable effect ofincreasing theζpotential; the effects of bivalent and trivalent cations on ζpotentialdecrease in turn, compared with monovalent cations, the effects on both the disperseddegree of α-hemihydrate gypsum particles and the setting time of paste are little.

研究还表明：由于一价阳离子能较大程度地提高石膏浆体的ζ电位，因而有效地提高了石膏颗粒的分散程度，对α半水石膏的水化加速作用很大，而二、三价离子对石膏浆体的ζ电位影响依次减小，对半水石膏颗粒的分散程度和浆体凝结时间的影响均不如一价阳离子作用大。

The particles of solid lubricant in the composite are distributed homogeneously and the interfaces of particles and matrix are well-combined.

该复合材料中固体润滑剂颗粒分布均匀，与基体合金的界面结合良好。

Nevertheless, due to the increase of the surface area and activity, the possibility of hydrogenolysis also increases so that more chloroform are generated with the use of nano-scale particles than with the micro-scale particles.

然而由於尺寸缩小，反应活性亦加大，奈米锡在水中对氢离子的竞争性提升，因此加强了氢解反应的发生机率，造成奈米化金属系统三氯甲烷的产率较粉末状金属系统高出许多。

This research is importantly significant of guidance to the systems of superfined particles such as preparation of nanometer materials, and to the aqueous systems of many particles such as hydrometallurgy and processes of extraction in chemical engineering.

这些研究，对于超微细颗粒聚集系统和液体中的多微粒系统(如湿法冶金和化工提取过程)，都有着重要的指导意义。

Our theory proves that macroscopicMackay packing icosahedral particles of 〓 could be more stable than 〓 particles withperiodic structure.
