It obtains that the transport operator A has no complex eigenvalue s, and the spectrum of the transport operator A consists of finite real isolated eigenvalues which have a finite algebraic multiplicity in trip Pas.

本文研究了板几何中一类具各向异性、单能、均匀介质迁移算子A的谱，得出了该算子A在带域Pas中无复本征值和由有限个具有限代数重数的实离散本征值组成等结果。

本文研究了板几何中一类具各向异性、连续能量、均匀介质的迁移算子的谱，得出了该算子A在带域Pas中无复本征值和由有限个具有限代数重数的实离散本征值组成等结果。

Another important result is that, which can be easily drown from the figure of probabilities of the states vs pump power with different x, or the common logarithm figure of the populate probabilities vs x , the increasing of the concentration of Er ions increase both energy transfer which populate the state and the cross relaxation process which depopulate the state, but the total result is that ion number of high lying states increase with concentration.

从不同掺杂浓度下各态布居几率或粒子数与光强的变化关系图可以看出，虽然掺杂离子浓度的增大同时增强了产生上转换荧光能态布居的能量迁移上转换过程和消耗该能态布居的交叉驰豫过程，但两者竞争的结果是较高的掺杂浓度对产生高能激发态的粒子数有利。

BMSCs may reverse the disbalance of Th1/Th2 cells by regulating the cytokines production to take an important part in treatment of EAE.

在体外BMSCs通过化学诱导可以向少突胶质细胞分化；在体内BMSCs能向病变部位迁移，并部分分化成少突胶质细胞，同时BMSCs通过调节免疫系统的炎症细胞因子表达、CD4+和CD8+T细胞数和Th1和Th2细胞平衡，对EAE起治疗作用。

It is found that a well-controlled pulse area is required for complete population transfer from if the dressing field is sufficiently strong and on resonance.

研究发现如果缀饰激光场足够强且发生共振，则在能级1 和能级4之间发生完全布局数迁移必须要求有一个恰当的脉冲叠加面积。

Even-level ladder system has been analyzed for population transfer by counterintuitive frequency-chirped laser pulse, in which intermediate states are strongly coupled by dressing laser field.

利用"反直觉"频率啁啾激光脉冲分析了偶能级ladder系统的布局数迁移，其中在缀饰激光场作用下N-2个中间态进行耦合。

This model used the finite—difference approximation to the advection— dispersion equation. The spatial derivatives in the flow equation are approximated by central difference written about grid—block boundaries and time derivatives are approximated by a fully implicit backward scheme.

水流方程的空间导数采用中心差分格式离散，时间导数采用隐式差分格式离散，建立了土壤水分和污染物在各种饱和度的条件下迁移转化方程耦合求解的二维数值计算模型。

Thus, centuries of Turkic migration and turkification of the region helped to formulate the modern Azerbaijani ethnic group.

突厥人向阿塞拜疆地区长达数个世纪的人口迁移以及该地区的突厥化最终形成了现今的阿塞拜疆民族。

The contribution of electrostatic interaction to the transfer volumes is predominant. The reduction in the electrostriction with increasing the concentration of salts was confirmed by the decreased hydration number.

氨基酸两性离子端基和阴阳离子间的静电作用对迁移体积的贡献是主要的，静电作用削弱了两性离子带电中心对周围水分子的电致收缩效应，造成氨基酸的理论水化数随盐溶液浓度的增加而减小。

Results After several days culture, the endothelial cells were proliferated and migrated, several lumens were performed on the endotheca in the control group; When 5% of Xue fu zhu yu Decoction were added, the number of proliferation and lumens in the endothelial cells decreased.

结果 未加药组经过数日培养后，内皮细胞增殖、迁移，在内壁形成了许多形状不规则的管腔结构。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
