1) center-of-mass motion

离子质心
1.
We propose a scheme for the generation of squeezed number states of the center-of-mass motion of a trapped ion.
本文提出一个方案以制备一个被囚禁在谐势阱中的离子质心运动的压缩数态。
2) impure ion center

杂质离子心
3) distance between two mass centers

分子间质心距离
4) centrifuge mass transfer

离心传质
5) centroid distance

质心距离
1.
Every point in high-dimensional space was grouped into some clusters using k-means cluster algorithm,then the weightee centroid distance of every point was computed based on the start distance and centroid distance of every point.
通过建模得到该DDM的四元组数据结构,对于高维空间中的数据点,通过k平均聚类算法将数据点聚成若干类,分别计算每个点对应的始点和质心距离,得到基于加权的质心距离,并将加权的质心距离作为每个数据点的索引键值,且用基于分片的B+树建立索引,得到了该索引的创建算法。
2.
Two steps are made in HD-Tree, first for every character in high-dimensional space are grouped into T clusters using hierarchy-based cluster algorithm, then the uniform start distance and centroid distance of every characters are pre-calculated and indexed by a partition-based B+-tree.
首先将n个书法字通过层次聚类聚成若干类,然后分别计算每个字对应的统一化始点距离和质心距离,最后将两者结合生成索引键值。
3.
We used centroid distance increment matrix to extract the CT heart shape characteristics.

本文利用质心距离增量矩阵方法对CT心脏图像的区域和边缘进行统一描述,再用质心距离增量矩阵方法提取CT心脏形状特征。
6) clarifixation

离心均质
补充资料:质心
质心 mass,centre of 质点系质量分布的平均位置。质量中心的简称。它同作用于质点系上的力系无关。设n个质点组成的质点系,其各质点的质量分别为m1,m2,…,mn。若用r1,r2,…,rn分别表示质点系中各质点相对某固定点的矢径,rc表示质心的矢径,则有rc= ![]() ![]() ![]() ![]() |
