The causes for the muffler attenuation trough was analyzed by the sound modal analysis and the sound pressure map analysis , and the improvement was put forward with the control measure of the long duct standing wave 用声模态分析和声压分布图分析的综合方法分析了消声器产生消声低谷的原因,并利用长管道驻波的控制方法加以控制。
We also performed a nonlinear curve fitting to the intensity relation curve between pumped light and upconversion emission light , and knew that the upconversion luminescence belonged to three - photon absorption 通过对上转换发光强度与泵浦源电流强度关系曲线的拟合,看到这种上转换是三光子吸收过程,这与通过能级图分析得到的结果相同。
First , we examine the economic concept of value and then apply it to people to develop the notion of human capital value . next we formulate a model to identify the factors that influence the value of individuals to organizations 首先对人力资本的价值涵义进行剖析,并运用一张模式图分析了个人对组织的价值决定因素,为人力资本的货币价值计量打下重要基础。
Through the phase diagram analysis and calculation , a production method to improve the quality of carnallite by evaporating the bittern from which the sodium chloride has been eliminated by brine mixing method is presented in this paper 摘要通过相图分析及计算,介绍了一种“由盐湖卤水兑卤除氯化钠后,首先获得成矿卤水,然后对其蒸发制取质量较好光卤石矿”的生产方法。
The strategy essential factor appreciation matrix for internal condition and the method of analysis in " radar " diagram and the method of the " swot " are the technique of synthesize analyze for the internal and external strategy environmental business enterprise “雷达”图分析法、企业内部条件战略要素评价矩阵和“ swot ”分析法是企业内外部战略环境的综合分析技术。
Then the methods using reachability graph to analyze static and dynamic structural performance of colored timed workflow net are improved , and the theorem verifying whether there are deadlocks or traps in concurrent workflow are put forward using reachability graph 通过可达图分析着色时间工作流网静态和动态性能,提出用可达图检验工作流中是否存在死锁和陷阱的判断定理。
The fifth chapter is about the process of mathematics model designing and case analysis . in this part , the concepts of equal - performance surface and equal - performance curve are given out and a new mathematics model of sophisticated performance appraisal is designed 在这一章中定义了等绩效曲面和等绩效曲线的概念,并设计了一种实用性很强的数?图分析工具? ?绩效综合分析图。
Based on the traditional chart algorithm , this paper proposed an improved chinese syntax parsing algorithm , which combined bottom up and top down strategies in order to enhance the efficiency and the precision of the chinese syntactic analysis 摘要针对传统的汉语句法分析算法进行改进,采用了自底向上与自顶向下相结合的线图分析方法,分析、设计和实现了一个汉语句法分析原型系统。
Meanwhile i give analysis method of constellation map . to update system , system optimization direction is taken as the most important thing , such as choice of modulator parameter , reduce power dissipation , improve circuit work frequency , 同时给出星座图分析说明;最为重要的是提出系统优化的方向,如调制参数的选择、如何降低功耗、如何提高电路工作频率,为系统的升级做了规划。
The disadvantage of extended state transition diagram is very complex , so we used petri net to analyze systems . petri net has many virtues . it can easily describe the actions of systems 但是由于这种扩展的状态图分析方法较复杂,而且也不能细致的描述具体系统的一些具体的特性,因此提出使用基于spn的分析方法,基于spn的分析方法能够非常细致的刻画具体系统,非常真实的描述系统的行为。
