异性极

In Chapter 2,a steady permeability identification problem in elliptic equa-tions for two-dimensional orthotropic medium is considered.We construct afunctional,obtain its first and second Gateaux differential,and prove that thefunctional is strictly convex on a convex admissible function set.We seek to iden-tify the permeability by minimization of the above functional.

第二章研究了二维稳态正交异性介质的渗透率反演问题，我们构造了一个泛函，求得该泛函的一、二阶Gateaux微分，证明了它在一个凸的容许集上的严格凸性，并使用极小化泛函即变分方法来求解此问题。

The pseudo delta function in seismic method is used to simulate the electric dipole source in finite element simulation, In this paper, the author extend it into three-dimensional case from which singularity from source is eliminated, and also the the stability of the equation is remarkably.

把应用于地震模拟中的伪delta函数引入到可控源电磁法中的有限元模拟中，并把其扩展到三维情况下，用源周围的小块区域代替偶极子源，从而消除了源点的奇异性，提高了方程组的稳定性。

In functional optical imaging,the very low SNR makes the sample covariance matrix have singularity,which brings the whitening the operation of the ICA denoising method to reduce the dimensionality,so the ICA denoising method will lost the signal detection ability.

在光学功能成像中，极低信噪比会使得样本协方差矩阵具有奇异性，因此导致Emir等人提出的ICA去噪方法在白化预处理过程会出现降维现象，最终使得该方法无法检测出信号。

The first the relation of AD model and the energy variety of image is educed by thermal diffusion and the diffusion equations based energy flux, and proves the image processing by energy flux sufficing maximum-minimum principle, the variety of image energy is equivalent to that of image intensity.

首先通过热扩散及热扩散方程、基于能量流的扩散方程，导出了向异性扩散模型与图像能量的变化过程之间的关系，并证明了利用能量流方法获得的图像处理过程同样满足极大极小原理。

The results showed that in the growth period of R. glutinosa, soil ferulic acid, vanillic acid, and vanillin contents had a persistent increase, while β-hydroxybenzoic acid content increased first but decreased then. The addition of ferulic acid (8 μg·ml-1), vanillic acid (08 μg·ml-1), vanillin (12 μg·ml-1), and β-hydroxybenzoic acid (30 μg·ml-1) in water culture had stronger inhibitory effects on R. glutinosa root length, root mass, fresh plant mass, and plant height. Treating with test phenolic acids except β-hydroxybenzoic acid increased leaf chlorophyll content significantly, compared with the control. After treated with test phenolic acids, plant SOD and POD activities decreased after an initial increase, and plant malondialdehyde content increased. In the treatment of ferulic acid, root SOD and POD activities were the lowest, and roots were rotted and dead.

结果表明：阿魏酸、香草酸和香草醛含量在地黄生长期表现为持续增加，而对羟基苯甲酸含量先升高后降低；外加阿魏酸（8 μg·ml-1）、香草酸（0.8 μg·ml-1）、香草醛（1.2 μg·ml-1）和对羟基苯甲酸（3.0 μg·ml-1）对水培地黄根长、根质量、全株鲜质量和株高有较强的抑制作用；酚酸处理使地黄叶片叶绿素含量降低，除对羟基苯甲酸外差异性极显著；经过酚酸处理的地黄幼苗SOD和POD活性为先升高后下降，丙二醛含量升高，其中阿魏酸的处理使根中酶活性降至最低，根部腐烂死亡。

If you're looking for the man or woman of your dreams, unsuspecting pheromones in your body scent are most likely playing a large and very clever role in mate attraction.

如果你在找梦中情人，你体内的费洛蒙香味极可能在吸引异性上扮演了很重要及灵敏性的角色。
