局部的

Then, by taking the local features provided by users as portions of the AAG, and the whole CAD model as the whole AAG, the problem of local feature matching is transformed into that of subgraph isomorphism. Subgraph isomorphism is a NP-complete problem.

在局部匹配过程中，用户输入的局部结构被表示成"子图"，待匹配的整体CAD模型被表示成"大图"；则在整体CAD模型中，检索局部结构的问题就被转换成在"大图"中寻找同构"子图"的问题。

Yu introduced in 1997 the localization Roe algebras , and shown that, to attack the Coarse Baum-Connes Conjecture, it suffices to prove that the local index map is an isomorphism from the coarse K-homology to the K-theory of the localization Roe algebras.

Yu受热方程方法的启发，引入局部化Roe代数，把粗Baum-Connes猜测的证明归结为证明从粗化K-同调群到局部化Roe代数的K-理论群的局部指标映射为同构。

The LMD algorithm uses extrema to define the local mean and envelope, then to smooth the mean and envelope. To decrease errors in the smoothing process by using moving averaging, a new local mean and envelope definition method (the spline-based LMD) is proposed. The upper envelope and the lower envelope are obtained by connecting the local maxima and the local minima using a cubic spline line. The local mean is defined as a mean of the upper envelope and the lower envelope. A nonlinear simulation signal and a practical vibration signal are decomposed by the LMD and the spline-based LMD.

LMD算法用极值点来定义局部均值函数和局域包络函数，然后用滑动平均来平滑均值和包络函数，针对用滑动平均平滑均值和包络函数误差较大的缺点，提出了采用三次样条对上、下极值点分别插值求得上下包络线，然后由上下包络线的平均获得局部平均函数，由上下包络线相减的绝对值获得局部包络的方法。

In this thesis, drug distribution in local tissues after topical administration of the ATPs was investigated with HPLC technique, concentration of ACF in skin and muscle remained high during 12hours. Pharmacodynamic of ATPs was evaluated with diclofenac gel as a control, and it was found that ATPs had stronger anti-inflammatory activity than diclofenac gel.The results of rabbit skin irritation test and Guinea pig skin allergia test make it certain that ATPs is safe for topical administration.
