聚点

In this study, the CPE processes of four different kinds of polyaromatic hydrocarbons, acenaphthene, anthracene, phenanthrene and pyrene, with two kinds of silicone surfactants, DC-193 and DC-190, were studied separately, and four different assisting methods for the phase separation of the CPE process including heating at a higher temperature, adding salts, centrifugation and stirring were introduced, respectively.

今利用两种聚醚型有机硅表面活性剂DC-193和DC-190，对蒽、菲、芘和苊四种多环芳烃进行浊点萃取研究，分别使用加热、加盐、离心和搅拌等辅助方法改变相分离过程的速度。通过测定表面活性剂富集相的体积百分率Vs/随时间的变化和最终的萃取率，研究上述四种不同辅助方法对相分离行为和萃取性能的影响。

This model adopts valuation indexes that extracted from transaction records as supplementations to the RFM parameters, and the algorithm for isolated point detection based on similar coefficient sum is also used to reduce the affection of isolated point.

该模型从客户交易信息中选取评估指标作为RFM指标的补充，并应用基于相似系数和的孤立点检测法降低孤立点对聚类结果的干扰。

This algorithm uses the gird and density threshold method to remove isolated points of data set,selects the initial seed points in propagating tree randomly,judges vegetal direction and executes sort according to the density-based distance,calculates cluster aim function by the propagating tree value.

算法利用网格和密度阈值去除数据集中的孤立点，从网格集中随机地选取种子点，以基于密度距离作为判断生长方向及分类的依据，以网格生长树的大小作为聚类目标函数。

All other matters had been examined and let go; there remained only that one small point of "knowingness".

那时！它们观照检验心识中心焦聚之点，只有「觉知」之点存在，观照检验之後就不再执著。

With thioglycollic acid as stablizing agent, cadmium selenide quantum dots were prepared, and the coating of CdSe with polylactide was studied.

摘 要：以巯基乙酸为稳定剂，制备CdSe量子点，并考察聚乳酸对量子点的包被。

When the mass ratio of polyacrylate-type depressant and naphthalene geepound is 1:1, the solidifying point of 0(superscript #) diesel decreases is 29℃.

点降低了13℃和25℃，聚丙烯酸酯类降凝剂与蔡斯以质量比1：1进行复配时，使0柴油的凝点降低了29℃。

The results show tat the acrylate copolymer depressant exhibits excellent effect of solidifying point reduction on the diesel, the solidifying point of 0(superscript #) diesel decreases about 14℃ and 18℃, respectively.

结果表明，聚丙烯酸混合酯对柴油有较好的降凝效果，0柴油的凝点降低了14℃，5柴油的凝点降低了18℃。

G. it is up to 80 eV when the cluster plane is parallel to the surface. In addition, the impact induced adsorption of C〓 cages was studied in detail. After impacting, the normal incident C〓 was found to move laterally on the surface due to the anisotropic interaction between the dimerized surface and the cage. Finally, it resided on the top of a dimmer or in the trough, which are the energy favored adsorption sites.

在能量为10-20eV的C〓富勒烯表面吸附动力学过程的研究中，我们还发现表面结构的不对称性会引起团簇-表面相互作用的各向异性，从而导致入射团簇在表面上有与入射方向垂直的的横向运动，最后吸附在两个二聚体的中心点和谷点，这两个位置是能量最低的的吸附组态。

It generalized the traditional k-means algorithm from the point of view of prototype selection. In detail, the kPC algorithm substituted hyperplanes for points used in k-means algorithm to be the prototypes and got these hyperplanes by minimizing the sum of the squared distances between each point and its closest hyperplane.

它从原型选择的角度推广了传统的k-均值算法，用超平面替代k-均值算法中的中心点来表示聚类原型，并通过最小化样本点到最近中心超平面平方距离之和来求取原型超平面。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
