Due to the loss of O and Si at reducing atmosphere, the amount of intergranular phase is lower than that of the sintering additives.

研究发现，由于烧结助剂中的O和Si在烧结过程还原气氛下的损失，使得烧结体中晶界相的含量明显低于烧结助剂的加入量。

In chapter 3 we further analyze the Moore-Penrose inverse of Kronecker product of A and B and the linear least squares problems involving Kronecker product, then obtain normwise mixed and componentwise condition numbers and the upper bounds similarly.

在第三章中我们进一步在列满秩情形下，对A与的Kronecker积的Moore-Penrose逆和带Kronecker积的线性最小二乘问题做了分析，同样得出了范数型，混合型和分量型这三种条件数及其上界。

W ithout assuming the boundedness, monotonicity, differentiability and Lipschitz continuity of the active functions, an algebraic criterion to ensure existence and globally exponential stability of periodic solutions was obtained.

在 放松该类神经网络激活函数的有界性、单调递增性、可微性及Lipschitz连续等条件下，得到了该类神经网络周期解的存在性与全局指数稳定的代数判据。

The problem that under what conditions the - resolvent operator of a maximal TJ - monotone set-valued mapping is a Lipschitz continuous single-valued mapping on whole space, which also answers the open problem mentioned above, is studied on finite dimensional Euclidean spaces.

借助于图收敛理论证明了有限维欧氏空间中的两个极大单调集值映射的和映射在较弱条件下仍是极大单调集值映射，并在此基础上讨论了一般集值变分包含问题解集的凸性、闭性和有界性。

This is hardly his first acting endeavor (I've liked him since Hyang Dan, where I thought he was very charming), but now that he's starring in a prime-time miniseries, I expect he'll be the next idol star to be declared a crossover success.

这几乎算是他的第一次演技尝试（我从香丹传时就开始欣赏他，我认为他很有魅力），但是现在他正在出演黄金时段的迷你剧，我期待他会成为下一个被公认跨界成功的偶像明星。

This new method will provide important basis for the research of the sea facies Mesozoic and Palaeozoic structure of Jiangsu lower Yangtse area and supervise the oil and gas exploration.

因此，在有一定钻井资料的条件下，通过采用大地电磁、地震资料开展有约束的联合反演，可以比较可靠地识别确定该目的层，为该区的海相中、古生界构造研究提供重要依据，以指导该区的油气勘探。

We developed an optimal perfectly matched layer method for scattering from cavity under both TM and TE polarizations by choosing a particular absorbing function with unbounded integral.

通过选取一类特殊的吸收函数，即在有界区域中其积分发散的函数，给出TM极化和TE极化情形下的洞穴电磁散射优化PML算法。

If P is a convex lattice polygon, and its pair-wise disjoint family of translates are also lattice polygons, whose union contains every lattice point, it is called a TLP .

若P为凸格点多边形，其内部边界不交平移覆盖平面格点集，则称之为可平移格点多边形TLP。记顶点数为v的TLP的内格点数的下确界为i ，得出i(5)=i(6)=1，i(7)=i(8)=4。

For a new kind of linear chaotic operator, one class of nonwande-ring operators (invertible and bounded linear nonwandering operators) are studied, and their invariance under small perturbation in finite dimensional separable Banach Space is proved.

对于一种新型的线性混沌算子―非游荡算子，研究Banach空间上的一类特殊非游荡算子―可逆线性有界非游荡算子，证明它的小扰动下的不变性。

Firstly, we present some sharp upper bounds on the adjacency spectral radius of graphs, and show that these bounds are somewhat better than the known ones.

首先，我们给出一些图的邻接谱半径的一些新的可达上界，并说明这些新结果在一定情形下比已有的结果要好。
