Nowadays , when designers want to develop a new control device , corresponding software will still be designed from the very beginning , which makes software development slowly . what ' s more , much work is redid , so that codes can not be reused 目前，开发不同功能的控制装置时，软件的设计仍然得从新了开始，这样就势必使得软件的开发速度慢，编程工作量大，而且部分的设计存在很大的重复性，代码的重用率低。
The mode superposition method , based on equivalent linearization and forcing decoupling method of non - classical damping matrix of energy dissipation systems , is the just one . at the same time , iterative process will increase computing workload and forcing decoupling method increase error 基于等效线性化的强行解耦振型分解法在一定程度上符合此要求，但此方法存在着迭代计算工作量大、强行解耦增大计算误差的不足。
Because condition complicated , heavy , usually very much difficult to make the ideal result within shorter time work load have , work for this planning and design and need one science fast choice material planning design method of field badly 由于条件复杂，工作量大，通常很难在较短的时间内取得理想的结果，为此规划设计工作亟需一个科学快速的选择料场的规划设计方法。本文运用系统分析的方法对砂石料场的优化选择进行研究。
This system can show the performance of the network , discover the problems , provide accurate data for further network optimization and solve the problems caused by manual dialing and testing . in this design . tms320lf2407 dsp and tc35 gsm module are adopted 该系统能够及时、规范、准确地体现现有网络的运行状况，发现网络存在的问题，为网络的进一步优化提供可靠的数据，同时也解决了人工拨打测试中工作量大，统计不全面等问题。
( 3 ) if we found the esd by handwork , the efficiency is low , the graphics isn ’ t canonical and fallible , and furthermore , we possibly can ’ t do it because of tremendous workload and complicated process . the method of computer aided esd model is the effective approach accounting for such problems ( 3 )手工建立esd模型效率低下,而且很不规范,容易出错,甚至会由于工作量大、过程复杂而难以开展,计算机辅助建模技术是解决这一问题的有效途径。
Moreover , due to the complexity of the structure of gap sensor , it is easy to work out in the course of using . because of the large number of gap sensor , the service workload is very large , and the fault location needs a long time , and costs too much 除此之外,由于间隙传感器的结构较复杂,电路使用的元器件众多,且磁悬浮列车所用间隙传感器的数量大,在使用过程中难免会出现故障,因此造成维护工作量大,检修过程中的故障定位时间长,维护费用高等问题。
But the standard development method for embedded linux system is lowly efficient and needs heavy workload , so , it ' s the most important thing to develop the embedded linux development toolkit with which the customers can customize an embedded system that meets there own special requirements 但是嵌入式linux系统传统开发方式存在着效率低、工作量大等不足，因此提供一种可以在短时间内定制满足用户特定需求的嵌入式系统的开发工具包无疑有着很重要的实际意义。
Moreover , there are drawbacks like difficulties in stimulation , complexity of calculation and heavy work in all these models because of many other factors . for example , the complexity of the dam structure , difficulties in measuring the physical and mechanical parameters of building materials and subgrade soil , stimulating the geologic structure of subgrade , predicting effects of loads , construction and environment on the dam and so on 此外，由于大坝结构复杂，建筑材料和地基岩土的物理力学指标难以测定，复杂地基的地质构造还很难模拟，荷载、施工及环境因素对水工建筑物的影响还很难准确预测，应用各种模型都存在着模拟困难、计算复杂、工作量大等不足。
With the rapid development of the internet , traditional ids reveals many limitations in the face of new attacks , such as large workload , slow responding speed , low accuracy and low efficiency , etc . in this thesis , the data mining approach to distributed intelligent intrusion detection system ( diids ) for updating detection rule library automatically is presented , which can maintain and update rules for improving the adaptability and extensibility of diids 传统的入侵检测系统由安全专家人工构造检测规则，但在网络日益发展的今天，新的攻击方法不断出现，这种方法已经暴露出很多局限性，如工作量大、响应速度慢以及正确率与效率低等。本文在原有的分布式智能入侵检测系统( diids )的基础上，提出应用数据挖掘技术实现入侵模式的自学习方法，有效地解决了该系统在检测规则知识维护及更新上的问题，使系统具有较好的适应性和扩展性。
This project develops a three - dimensional cad system module for electric switch cabinet . it is based on unigraphics nx ( ug nx ) which is a integrated cad / cae / cam software of ugs corporation of american and visual c + + 6 . 0 which is a classics programming software of microsoft corporation , the project has a further study in it by synthetically using a series of development methods and electric switch cabinet ’ s serialized characters : complex structure , tight time limit for a project and big workload . the author has mainly carried on the following researches in this paper : studied the solid modeling of ug nx thoroughly , including the application of solid modeling , express and parameter - driven modeling 本课题是在windowsxp平台上,基于美国ugs公司的cad / cam / cae一体化软件unigraphicsnx ( ugnx )和microsoft软件公司的经典编程软件visualc + + 6 . 0 ,利用ugnx良好的开放性,通过一系列的二次开发方法的综合运用,针对电气开关柜结构复杂、工期紧、工作量大、部分零部件已经系列化等特点,开发出了专用电气开关柜三维cad模块。
