On the base of some research results , the interior and exterior model of gis are set up in this paper , and very fast transient overvoltage ( vfto ) can be calculated via the software that is called emtp - atp 本文立足已有一些研究成果，建立了一个实际gis的内部和外部的模型，并借助emtp - atp软件模拟计算了由隔离开关操作引起的特快速暂态过电压（ vfto ） 。
At the same time the influence of the cavity in front of slow - wave structure and the length of a smooth drift tube which connect two sections of slow - wave structure are also studied in this dissertation 然后利用magic粒子模拟软件模拟了反射器对器件工作性能的影响,同时还分析了慢波系统前面的腔体以及两段式慢波结构中过渡段的长度对器件工作性能的影响。
We simulated and adjusted the energy and dose of implant impurity by the aid of silvaco software so as to confine the vt value in a reasonable range and finally we got eligible device samples 最后，我们基于silvaco软件模拟并调节了杂质注入的能量和剂量，并结合实验结果调整了pmos管和nmos管的阈值电压，制备出了合格的bmhmt工作模式的soi异质结mosfet单管。
The main content in this dissertation include : 1 . the basic principle and signal processing of sar imaging are described . single target and mult - target echo imaging are simulated using dechirp algorithm by software 本文完成的主要工作有: 1 .讨论了sar成像的基本原理及其信号处理,使用去调频斜率算法分别对弹载sar的单点目标和多点目标回波成像进行了软件模拟。
The x processor verification unified verification environment consists of three parts : software simulation platform , hardware emulation platform and fpga prototype platform . in this project , using our verification method , x processor is well validated 在这一思想的指导下,设计实现了统一环境的系列验证平台,包括软件模拟平台、硬件仿真加速平台以及fpga原型系统平台。
At the same time with the development of mordern technology , watercraft steer automatization comes true . the " non - paper plotting " that mark by pc instead of by human , can decrease the cost of hardware and 同时现代科学技术的发展，使船舶驾驶自动化逐渐成为现实， “无纸化”的人工标绘，即刚计算机软件模拟标绘的过程，在人机交互的界面下进行雷达标绘训练，有利于减少硬件的投资。
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） 。
Firstly , in this paper the theory of light propagation and diffusion is introduced . the software of femlab based on finite element method is used to simulate the nir light fluence in the tissue , which is just the forward problem of optical ct 本文首先介绍了光在组织中的传输及其扩散近似理论,并用基于有限元方法( fem )开发的femlab软件模拟了光在生物组织中的分布,此即光学ct的正向问题。
Optical field intensity has been simulated by beam transmission method ( bpm ) , bend loss has been calculated by used of the method of conformal transformations , gain has been accounted by the method of lines , and different curved optical waveguides have been compared in the last 采用bpm软件模拟光场在弯曲波导中的分布,用保角变换和射线法计算其弯曲损耗及增益,最后对不同结构的弯曲波导进行比较。
A static / dynamic characteristic test was done to obtain all dynamic parameters of the lathe , then the software ansys for fea was used to simulate and display various vibration modes and natural frequencies with the guide joint parameters taken into account 首先利用静、动态特性实验得出机床的各项动态参数，然后用ansys有限元分析软件模拟和显示机床在考虑导轨结合面参数条件下的各阶模态下的振型和固有频率。
