相对论

A lot of people think the physics before the theory of relativity is absolutism, the theory of relativity and absolutism run in the opposite direction completely.

很多人都认为相对论以前的物理学是绝对论的，相对论和绝对论是完全背道而驰的。

In addition, we note that the Newton limit of the relativistic hydrodynamics equations is the classical compressible fluid Euler equations system. This is one of the motives that we research the relativistic hydrodynamics equations.

此外，我们注意到相对论流体力学方程组的Newton极限即为经典的可压缩流体力学Euler方程组，这也是我们研究相对论流体力学方程组的动机之一。

The culture philosophy is often comprehended at three meanings: science of culture, primary theory of culturology and ph

文化进化论与文化相对论作为人类理解自身文化的两种前提性思维，它实际上反映着人类对人类自身和人类存在的不同理解。文化相对论坚持了

In this book the emphasis is on the role of the Dirac equation in the relativistic quantum mechanics of spin-1.2 particles. We cover the range from the description of a single free particle to the external field problem in quantum electrodynamics.

本书着眼于Dirac方程在1/2自旋粒子的相对论量子力学的作用，覆盖了从单个自由粒子的相对论量子力学到量子电动力学的外加场问题。

At first, we introduce in detail relativistic mean-field theory, where a common Lagrangian density is presented. Starting with this Lagrangian density, we can obtain the Dirac equation and Klein-Gordon equations for nucleon and meson field by using Euler-Lagrangian equation.

本文首先详细介绍了相对论平均场理论的一些公式推导，给出了常用的一般的相对论平均场的拉格朗日量，从这个拉氏量出发，利用Euler-Lagrange方程就可导出核子与介子场的运动方程。

At first even many scientists didn't really grasp relativity, prompting Arthur Eddington's celebrated wisecrack (asked if it was true that only three people understood relativity, the witty British astrophysicist paused, then said,"I am trying to think who the third person is").

一开始，甚至很多科学家都不能真正理解相对论，这让我们想到爱丁顿著名的俏皮话（当被问到是不是只有三个人懂得相对论的时候，这位机智的英国天体物理学家停顿了一下，然后说："我正在想这第三个人是谁"）。

Using the extended relativistic multi-configuration Dirac-Fock theory and the general-purpose relativistic atomic structure program 2(GRASP2) with quantum electrodynamical effect and breit correction, we have calculated the energy level structures, transition wavelengths, transition probabilities, oscillator strengths, energy level lifetimes, level widths and ionic average lifetimes of As-like Au~(46+), Ge-like Au~(47+) and Fe-like Au~(53+).

根据扩展的全相对论多组态Dirac-Foek理论，采用"多功能相对论原子结构程序GRASP~2(General-Purpose Relativistic Atomic Structure Program 2，1992)"，考虑量子电动力学效应和Breit修正，计算了激光金等离子体中类砷金Au~(46+)，类锗金Au~(47+)和类铁金Au~(53+)的能级结构、跃迁波长、跃迁几率、振子强度、能级寿命、能级宽度和离子平均寿命。

In this arfide,the equation of motion of relativistic rocket is presented by mechanical laws of relativity .

本文利用相对论的力学规律，给出了相对论效应的火箭运动方程。

The non-relativistic energies and wave functions were determined by Rayleigh-Ritz method. The relativistic effects, including the correction to kinetic energy, the electron-electron contact term, and the orbit-orbit interaction, Darwin term, and mass-polarization effect on the energies were calculated by using first-order perturbation theory. In order to obtain a more accurate result for the larger Z system, the quantum-electrodynamics correction should be included. This correction to energy can be evaluated for the valence electron by using a hydrogenic formula with an effective nuclear charge, Z. The ionization potential, the excitation energies and the fine structure split-tings for a lithium-like ion with higher nuclear charge (Z=26) were calculated.

非相对论能量用Rayleigh-Ritz变分法确定，包括动能修正、电子—电子接触项、轨道—轨道相互作用项以及Darwin项的相对论修正和质量极化项由全实加关联波函数的一阶微扰给出，量子电动力学修正由有效核电荷方法和类氢公式计算；给出了较高核电荷(Z=26)类锂体系1s^2nl组态的电离能、激发能和1s^2np组态的精细结构劈裂。

Nuclear Physics 1930, the Star of energy will be satisfied with the solution to the rapid development of the internal structure of stars; Hours map and based on the experimental results, the establishment of a stellar evolution of scientific theory. Einstein's general theory of relativity, in 1917 by the structure of the universe, the establishment of a relativistic cosmology. In 1929 the Hubble Space Telescope found redshifts and distances of the future, relations between the people of the gravitational theory of general relativity River from the data objects, size and structure of the material movement and the formation of modern cosmology.

三十年代原子核物理学的发展﹐使恒星能源的疑问获得满意的解决﹐从而使恒星内部结构理论迅速发展﹔并且依据赫罗图的实测结果﹐确立了恒星演化的科学理论。1917年爱因斯坦用广义相对论分析宇宙的结构﹐创立了相对论宇宙学。1929年哈勃发现了河外星系的谱线红移与距离间的关系﹐以后人们利用广义相对论的引力理论来分析有关河外天体的观测资料﹐探索大尺度上的物质结构和运动﹐这就形成了现代宇宙学。

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
