Using Biot's 2D elastodynamic theory solves the saturated soil equation. The Fredholm integral equation of the second kind can be built by using the fundamental solution of circular load, the compatibility condition and superposition method. The Fredholm integral equation of the second kind of pile groups can be solved by using numerical method. The numerical solutions of pile groups axial forces, pore pressures under vertical harmonic loading and shear forces, moments and pore pressures under horizontal harmonic loading can be obtained.

采用Biot提出的三维波动原理，利用圆形简谐载荷作用下的Biot固结方程的基本解和桩土之间的变形协调条件，并采用叠加原理得到饱和土中群桩的第二类Fredholm积分方程，应用数值法求解群桩的第二类Fredholm积分方程，得到在垂直简谐载荷作用下群桩的轴力、孔压随桩身变化的数值结果以及在水平简谐载荷作用下群桩的剪力、弯矩和孔压随桩身变化的数值结果。

For a high laser intensity and small spot size, an electron may escape from the laser and can retain energy gain.We obtain analytical expresses of electron instantaneous momentum. Taking the plane wave of Gaussian laser for an example, we derive electron distribution function over instantaneous values of electron momentum and energy.

本文考虑电子初始温度不高(约100eV)以及脉冲长度很短(约4-6个激光波长)时，也能得到两群高能电子群；在脉冲长度极短(仅有2-3个激光波长)和电子初始温度不太高的情况下，就有明显的三群高能电子群出现，且如果激光功率密度大于5×10~(18)wcm~(-2)时，高能电子的温度也达到MeV。

In addition,we prove that the invariant rings of the maximal subgroups of class C_1 of the general linear group are polvnomial,and so do the invariant rings of root subgroups of the special linear groups.

另外，证明有限域上一般线性群的C_1类极大子群和特殊线性群的根子群的不变式环是多项式的。

Firstly, knowledge spillovers destroy the normal Hotelling process, and lead to regional industry cluster.

本文研究了产业集群发生的机制，进而对集群发生的两个"剑桥现象"作了解析，从而得到关于产业集群的一些规律认识：1知识溢出破坏了正常的霍特林过程，使得区域发生集群。

Rusults Individuals in individualism culture reported higher life satisfaction than those in collectivism culture,but no sigmficant differences were found on positive or negative affect; individuals in individualism culture tended to be more idiocenrism, but hose in collectivism culture tended to be more allocentrism; the congruence between individual and ecological culture led to higher SWB, but incongruence between individual and ecological culture did not decrease individuals' SWB necessarily. The oriemtations of harmony and self concern predicted SWB across different cultures.

结果 个人主义文化群的生活满意度高于集体主义文化群，但在积极情感和消极情感体验上无显著文化差异；个人主义文化群表现出更高的自我中心取向，而集体主义文化群表现出更高的他人中心取向；个体文化取向与生态文化相一致是主观幸福感的重要来源，但个体文化取向与生态文化不一致并不一定会降低个体的幸福感水平。

This paper studies the group invariant np, the number of G-orbits of Sylow intersections, which plays an important role in the research of block theory and indecomposable modules of finite groups.

在有限群的研究中，Sylow p-子群无疑起到了非常重要的作用；同样，Sylow p-子群交在有限群不可分解模和块论研究当中的作用也是不容忽视的。

Firstly, we prove the existence and the uniqueness of the hyperfocal subalgebra when the coefficient field is split for a defect pointed group; then, considering the structural pattern of source algebras over arbitrary fields, by means of G-acted groups, we reduce the existence and the uniqueness of the hyperfocal subalgebra over an arbitrary field to the case that the coefficient field is split for a defect pointed group and the inertia group stablizes a hyperfocal subalgebra.

首先我们证明了如果系数域对亏点群是分裂的，则源代数的超聚焦子代数存在且共轭唯一；然后通过考虑任意域上源代数的结构模式，以G-作用群为手段，将超聚焦子代数的存在性和唯一性归结为系数域对亏点群是分裂的情况下惯性群稳定的超聚焦子代数的存在性和唯一性。

According to [2], we know that if X is a reflexive Banach space and T is a strongly continuous semigroup on X with the infinitesimal generator A, then the adjoint semigroup T~* is also a strongly continuous semigroup on X* and its infinitesimal generator is A~*, the ajoint operator of A.

由文献[2]我们知道，如果X是一自反Banach空间，那么X上强连续半群T的对偶半群T~*也是X~*上的强连续半群，并且其无穷小生成元为半群T的无穷小生成元的对偶。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
