According to the feature of seaport container logistics system , this dissertation makes research of scheduling and simulation modeling of the system as folio wings : in the first chapter , simulation modeling theory of discrete system and its development is summarized , the theoretical applications in logistics system are also presented 全文一共分为九章。第一章为绪论，综述了离散系统仿真建模的理论方法、发展概况及其在物流系统中的应用现状，同时综述了虚拟现实技术的发展及虚拟现实技术在系统仿真领域的应用前景。
The folio wings are the content of the four part : the first part : the theory delimit of taxation culture starting with the definition of culture , author use the method of " genus and generic distinction " in order to conclude the definition of taxation culture 四部分的具体内容如下：第一部分：税收文化的理论界定从文化的定义入手，运用“属加属差”的定义方法，分析归纳出税收文化的定义，界定税收文化的内涵和外延。这一部分的写作意图是明确税收文化的基本界定，为下文打下理论基础。
In this paper , the folio wings are introduced briefly : holonomic theory ; the basic idea that d . zeilberger used to prove identities using holonomic theory . and wu method is generalized to the non - commutative weyl algebra . furthermore , dialytic method of elimination is replaced by wu method , so the prove can be extended from the single - variable hypergeometric identities to multi - variable ones 本文简要介绍了完整性理论， d . zeilberger利用完整性理论证明恒等式的基本思想，将吴方法推广到不可交换的weyl代数上，用吴方法取代了d . zeilberg在证明完整性函数恒等式的理论框架中的析配消元法，从而将这种证明理论由单变量超几何恒等式的证明扩展到多变量超几何恒等式的证明。
This essay is based on modern pedagogy , psychology and the characteristics of math to analyze , sort out and re - annotate the formula , trying to put on it a more unified thought . the author also focuses on the theoretical research of the formula to find out the meanings , connection of the four sections , studies its distinguishing feature and farsightedness , and explores some new opinions by the research as the folio wings : 1 . " divert from form to content " also reflects the principle of ability center 本文从现代教育学、心理学出发，又从数学的学科特点出发，对32字诀的教学原则重新进行了解构、梳理、诠释以及初步的整体性思考，再次着重从理论层面上探究32字诀中各句的含义、相互之间的关系和其特色以及前瞻性，并且在探究中提出了有一定新意的见解： 1 、 “淡化形式，注重实质”还体现了“能力中心”的教学理念。
Lydia s intention of walking to meryton was not forgotten ; every sister except mary agreed to go with her ; and mr . collins was to attend them , at the request of mr . bennet , who was most anxious to get rid of him , and have his library to himself ; for thither mr . collins had followed him after breakfast , and there he would continue , nominally engaged with one of the largest folios in the collection , but really talking to mr . bennet , with little cessation , of his house and garden at hunsford 除了曼丽之外，姐姐们都愿意跟她同去班纳特先生为了要把柯林斯先生撵走，好让自己在书房里清净一阵，便请他也跟着她们一起去。原来柯林斯先生吃过早饭以后，就跟着他到书房来了，一直待到那时候还不想走，名义上在看他所收藏的那本大型的对开本，事实上却在滔滔不绝地跟班纳特先生大谈他自己在汉斯福的房产和花园，弄得班纳特先生心烦意乱。

So a computer - aided alignment method for a series of reference lens is studied in detail in this paper . based on analyzing the optical quality affecting factors and optical design , the folio wings are described in detail in this paper : ( 1 ) how to choose merit function of optical quality in terms of the specific reference lens , and sensitive structure parameters to optical quality would be determined according to their tolerance data ; ( 2 ) discussing the relationship between the aberrations and the misalignment of reference lens ; ( 3 ) building the mathematical model for the misalignment optical system , and then calculating the misalignment value by the alignment software compiled on zemax and matlab platforms ; ( 4 ) experiments are made to examine the computer - aided alignment method . the theoretical and experimental data and plots are given in the paper 本文在分析标准球面透镜的设计及其光学质量的影响因素基础上，开展了以下四个方面的研究： ( 1 )根据系列标准球面透镜的具体结构特点，选择透镜的质量评价指标，研究标准球面透镜的公差分布，确定敏感结构参数； ( 2 )研究光学质量评价指标与失调量之间的函数关系； ( 3 )建立数学物理模型，根据球面波的实测结果，求解待调系统的失调方位和量值，研究原理上实现计算机辅助装调的可能性，在zemax和matlab平台上编写辅助装调软件； ( 4 )建立实验装置，实际研究标准球面透镜的计算机辅助装调方法，文中给出相应的理论分析及实验数据和曲线。
However , the movement and transformation of n in soil under fertigation remains unclear . the methods of simulation experiment and culture experiment were used to study the movement and transformation of n in soil under fertigation by drip irrigation . the main experimental results were shown as folio wings : ( 1 ) the water infiltration under drop irrigation is a point infiltration ; and the soil moisture in vertical and horizontal directions was increased with the irrigation time , and the movement rate were decreased with the irrigation time 本研究采用室内模拟试验和生物培养试验相结合的方法，研究了在滴灌施肥条件下，化学氮肥施入土壤后的迁移、转化规律以及对作物生长的效应，获得了以下主要结论： ( 1 )滴灌条件下水分以点源入渗土壤，水平和垂向的湿润锋均随入渗时间的增加而逐渐变大，在入渗开始阶段湿润锋的推进速率较大，随入渗时间的延长，湿润锋的推进速率逐渐变慢。
