We call the new quantum phenomenon that ca n ' t be explained by classical theory non - classical feature of cavity field . it has been proved by experiment , that quantum states of cavity field can exhibit three non - classical features , i . e . photon antibunching effect , sub - poissonian statistics distribution , and squeezed states 在光场与原子相互作用的过程中会出现某些不能为经典理论所解释的新的量子现象，人们统称这些现象为光场的非经典效应，目前实验上所观测到的非经典现象有光子的反聚束效应、亚泊松分布和光场的压缩效应。
The key components in laser gyro is he - ne ring laser , and the reciprocal action theory between light and medium is the base in studying the ring laser , use the lamb half classical theory , and on the base of density matrix theory , the optical brounch equation was established , which described the movement of amplifying medium atom in the ring syntonic cavity , and according to the medium polarize theory the self consistent equations was deduced , which describe the light intensity and phasic of the counter - propagating wave . on the basis of this equations , adopted the simulation software matlab and virtual instrument programming language labwindows / cvi , we can do some simulated experiments in study the phenomenas such as amplify and dispersive characteristic of medium , mode pushing effection , burned hole effection and pattern competition , lock - in of frequency and the characteristic of light intensity and phasic of the counter - propagating wave in laser gyro 激光陀螺的核心部件为he - ne环形激光器，而掌握光与介质的相互作用理论是研究激光器的关键，采用拉姆半经典理论为主，在密度矩阵理论的基础上，推导环形谐振腔中描述he - ne气体增益介质原子运动的光学布洛赫方程，运用介质极化理论得出描述激光陀螺反向行波的光强、位相所满足的自洽场方程组，在此基础上，运用matlab仿真软件和虚拟仪器编程语言labwindows / cvi ，对激光陀螺中的介质增益色散特性、频率牵引效应、烧孔效应及模竞争、闭锁效应及环激光的光强和相位特性进行仿真试验研究，并且运用全量子理论，对激光工作原理进行分析，得出二能级系统单模辐射场的光子数密度分布，得出激光场的光子统计分布，仿真激光场的动态建立过程。
The first part , which is also the first chapter , gives the comments on the theoretical research about the formation mechanism of stock price , such as mpt , emh , capm , behavioral finance , arch and market microstructure theory . these authentic proof models provide a basis of the analysis in the paper 笔者主要综合回顾了西方金融学在股票定价机制方面的经典理论和模型的发展状况，同时对国内在这些理论和模型方面的相关研究和实证成果进行了归纳，并针对问题提出相应的看法。
The logic structure is as follows : the full text is divided into four chapters , chapter i is about the effectiveness of our interest rate policy qualitative analysis ; chapter ii is about regional differences exist interest policy analysis , analysis of the existing regional disparities ; chapter iii monetary policy to reduce regional disparities in economic development , chapters iv is the solutions to the problem . the following are some of the main elements : chapter i mainly deals with interest rates , interest rate policy effectiveness , and factors which affect interest rate policy effects 本文研究的基本思路是:首先,从经典理论出发,在利率政策是有效的前提下,开始本文的研究,并论述了影响利率政策效应的主要因素;其次,分析我国区域经济金融发展方面存在的差异,以及这些方面差异的存在,是如何导致的影响利率政策效应的主要因素产生差异的,通过分析影响因素的差异,得出不同的区域利率政策的效应是不同的。
All cross sections of neutron induced reaction , elastic scattering angular distribution , neutron energy spectrum and double differential cross sections were calculated by using optical model and the semi - classical model of multi - step nuclear reaction processes based on the hauser - feshbach and exciton model in the energy region up to 20mev 应用光学模型和以复合核平衡态理论( hauser ? feshbach理论)及激子模型为基础的核反应多步过程的半经典理论，计算了当中子入射能量低于20mev时n + ~ ( 112120 ) sn反应的所有中子入射截面、弹性散射角分布、出射中子能谱以及出射中子双微分截面。
So far we have unified the principles of relativity special and general and quantum mechanics on the foundation of tast , thus the principles of existing theories of physics become the results of tast . from the development of pure science , we see that we take some things as phenomena while taking other things as essence to describe our experiences . when we reach a deeper level in science , the essence or principles at the upper level become the manifestation and we use more comprehensive principles as essence 近年来有关反物质，负时空的概念已逐步从科幻作品中进入到一些专业书刊中，但从理论上承认反物质负时空和负能量等的存在还需要相当的勇气，因为在我们看来，客观存在必须是实实在在的东西，负时空概念显然与传统观念格格不入，是经典理论的禁区，但对于理论工作者来说它绝不能成为想象力的桎梏。
There are also some notes for your attention : 1 . since this thesis covers the latest development of constructivism and information technology , effectiveness becomes the principle for material collecting and analysis . therefore some classic and traditional theories are briefly dealt with 对于本文，还需要提请注意以下几点：由于本文的教学和技术两大主线涉及了建构主义和信息技术的最新进展，所以在资料收集和分析上比较注意时效性和针对性，对一些为人所熟悉的经典理论只进行了简要表述。
After analyzing the soil stress , flexure moment data of central section of the sheet , and the flections data of two kinds of holding sheet models which are different on span , the paper gets the horizontal and vertical soil stress distribution rules and compares the result of the exam with calculating result of classic soil stress theory 通过对两种跨度的挡板模型的土压力、挡板跨中弯矩、挡板跨中挠度值的分析总结，得到了挡板后土压力沿高度及水平方向的分布规律，并在土压力分布形式及数值大小与经典理论作了比较。
