查询词典 aggregation function

During the process of peptization and hydrothermal crystallization, the aggregation behavior and the resulting morphology of nanocrystalline titania (TiO2) were studied by X-ray diffraction, scanning electron microscope, and dynamic light scattering techniques.

通过XRD、SEM和动态光散射粒度测定仪研究了胶溶及水热晶化过程中纳米TiO2晶粒聚集行为及形貌。实验结果表明，在胶溶无定形沉淀过程中所形成的大小为10-15nm的锐钛矿型胶粒或金红石型胶粒易定向聚集成更大的、具有(30-50)nm×(80-100)nm的次级晶粒。含有次级晶粒的溶胶前驱液在水热晶化过程中，次级晶粒发生崩裂并生长成结晶度更高的大小约为10-30nm球形和大小约为20-60nm棒状纳米TiO2

OBJECTIVE To observe the effects of phenolic alkaloids of menispermum dauricum on platelet aggregation and explore its mechanism.

目的 观察蝙蝠葛酚性碱对血小板聚集的影响，探讨其抗血小板聚集的作用机制。

An average of 35.6±37.0 flying birds per aggregation was observed, almost all of them associated to chinstrap penguin Pygoscelis antarctica groups. The most common species were kelp gulls Larus dominicanus, South Polar skuas Catharacta maccormicki, pintado petrels Daption capensis and southern giant petrels Macronectes giganteus.

发现每个取食集团中有35.6-37.0只善于飞翔的海鸟，其中几乎都有纹颊企鹅群，黑背鸥、灰贼鸥、花斑鹱和巨鹱是各集团中最常见的鸟类。

It indicates that the different parts of the cattle-egg stone samples in different colours all mainly compose of pyrophyllite, coexisted by two kinds of polytype of monoclinic and triclinic pyrophyllite, and the average crystal structural formula is Al4.04 Si7.89 Al0.11O204. The aggregation of pyrophyllite arranges with no direction, and the crystal size of the single pyrophyllite crystal in the weathering skin is a little bigger than that in the basal part.

结果表明，不同颜色牛蛋石样品的不同部位皆以叶腊石为主要成分，并以叶腊石的单斜和三斜两种多型共存，其平均晶体结构化学式为Al4.04[Si7.89Al0.11O20]4；其叶腊石集合体呈无定向排列，风化皮中叶腊石单晶的粒度略大于基体中的。

This phenomenon could be explained by the collapse of mesopores and the aggregation of pore walls.

这个现象可以被解释为中孔的瓦解和孔隙壁的集合。

A new multiple attribute decision making method was presented for ranking alternatives based on fuzzy preference relation about the alternatives provided by the decision maker. A linear goal programming model was constructed to determine the weight vector of attributes and to rank the alternatives. In this model,the ranking of alternatives incarnates an aggregation of the preference information about the alternatives and the decision matrix,and reflects the subjective preference of the decision...

针对多属性决策分析中决策者给出关于方案的Fuzzy偏好关系，提出了一种新的多属性决策方法·该方法是通过建立一个线性目标规划模型来确定属性的权重向量并相应地进行方案的排序，得到的方案排序结果体现了决策者给出的方案偏好信息与决策矩阵的集成，并最大程度地反映了决策者的偏好·最后给出了一个算例
