查询词典 efficient point

If a is a nonperiodic recurrent point and there is a period point in orb, orb doesn't contain an innumerable scrambled set.

结果 a是符号空间中的非周期回复点，且orb包含一个子转移σ的周期点，则orb不包含一个不可数混乱集。

Firstly, the eigenvalue problem of a class of second order elliptic equation with critical potential and indefinite weights is considered. Then, using critical point theory, Trudinger-Moser inequality and the properties of the first eigenvalue, we prove the existence of a nontrivial solution for a class of nonlinear elliptic with critical potentialand indefinite weights in R~2. Secondly, we prove the existence of nontrivial solutions for a class of subcritical and critical elliptic systems with indefinite part in R~2 byusing a generalized linking theorem, Trudinger-Moser inequality and concentration-compactness principle.5. The existence of at least three weak solutions for discrete boundary value problem is established by using a three critical point theorem introduced by Ricceri.

On the basis of SIF normalized coefficient values gained from a vast amount of fatigue crack Propagation experiments, the approximate expressions of stress intensity factor on the deepest Point and surface Point of surface crack are obtained by means of stepwise regression analysis.

在大量疲劳裂纹扩展实验取得的SIF正则系数值的基础上，用逐步回归分析得到了这种情况下表面裂纹最深点和表面点的应力强度因子近似式。

In this new algorithm, 2-D X-ray images are collected for Ca, Si, Al, Fe, S, K, Mg, and grey-level value of the same point in these images are normalized and arranged as a vector in a particular order. In this paper, the vector is named as character vector, for it can be used to characterize each point in cement pastes 2-D image.
