The method for studying ehtv and the parameters is based on calculating a design model with program of doe - 2 , the model and the condition have representational , the scientific decompose for these parameters Ehtv指标及相关参数的研究方法是建立在对一个设计模型用动态模拟程序doe - 2进行模拟计算的基础上，研究的关键是建立的模型及计算条件要具有代表性，分解各因素的方法要科学。
The amount used is significantly lower if you use ibm s synchronous data compression hardware feature than if you use the db2 software simulation program when db2 is started , it determines whether or not the hardware compression feature is available 与使用db2软件模拟程序相比，使用ibm的同步数据压缩硬件可以大大减少所消耗的cpu资源（当db2启动时，它将判断硬件压缩特性是否可用） 。
The main results of this article are : ( 1 ) the software that is to simulate the transportation of ions in rf glow discharge , in which a simple method to determine the original states of the ions ( original velocities and positions ) is recommended 本论文的主要结果有： ( 1 )编写了射频辉光放电过程中入射离子的输运模拟程序，并提出了一种简单的决定离子初始状态(位置、速度)的方法。
Many theoretical analysis and numerical simulations on many kinds of the factors that will do more effect on the beams with the help of the mature electronic trajectory program - - - - - egun , a set of formula and some program that were my code have been done 首先对计算电子轨迹的数值模拟程序egun的工作原理[ 35 ]及程序的应用进行了详细的分析和了解,对电子光学系统的基本理论与计算方法进行了详细的阐述。
In icf research , the diagnosis of laser - produced plasma is a important area . it is important to research each mechanism of interaction between laser and plasma and verify stimulant program , then to direct designs for driver and target form 对强激光产生等离子体的诊断，是icf研究中的重要领域。它对于研究激光等离子体相互作用的各种机制、校验模拟程序进而指导驱动器和靶形的设计等方面有十分重要的意义。
In vehicle dynamics study before , we always take one model or process as our research object . and , when developing simulation program , the whole program like a water fall pouring down , makes the program difficulty to maintain . so 以往在研究车辆动力学模型时，多是就动力学的某部分模型或过程进行研究，并且在开发模拟程序时，多使用过程式的建模和编程方法，使得建立的模型条理不够清晰，编制的程序可读性和易维护性不高。
This tusk is done by program constructed by appropriate method . so , this thesis talks about electron trace modeling by investigating method of calculating electromagnetic field , mathematic model of modeling electron trace , and how to program 本论文从电磁场的计算方法、电子轨迹模拟的数学建模和电子轨迹模拟的程序设计三个方面对强流电子枪电子轨迹的模拟进行了研究,并利用fortran语言编写了强流电子枪电子轨迹模拟程序vbgun 。
