The author launches elaboration from the way of “ law - regulation law - economic regulation law ” and thinks regulation and efficiency are special characters of economic regulation law 作者从“法?调制法?经济调制法”的路径展开论述，认为经济调制法的特殊品格是调制性与经济性。
We embed copyright watermark utilizing variance modulation on dc coefficients of dct transform ; and in the spatial domain , we embed authentication watermark gemerated from one - way hash function , lossless compression and least - significant - bit embedding 在频域中,我们采用了方差调制法,对版权水印进行嵌入;在空域中,我们采用了单向散列函数、无损压缩和最低有效位等方法,对认证水印进行嵌入。
The author believes we should differentiate the academic significance economic law and the semantic significance economic law , refer with economic law called the semantic significance economic law and with economic regulation law called the academic significance economic law 作者认为应将学术意义上的经济法与语义学意义上的经济法相区分，用经济法来指称语义学意义上的经济法，用经济调制法来称谓学术意义上的经济法。
He induces organization failures through market failures and state failures and defines efficiency of economic regulation law as economic regulation law can effectively solve the question of organization failures and cause organizations to dispose the resources close most superior condition 通过市场失败、国家失败归纳出组织失败，并将经济调制法的经济性界定为经济调制法能够有效的解决组织失败问题，使组织配置资源接近最优状态。
In this dissertation we make used some methods of modulation with electronics parameter and modularization ideas of unit of function circuit , to study the control and synchronization of hyperchaos in system combined electronics with optics ( for short sceo ) , and research its applications of secure communications experiment 本文利用电学参数调制法和单元功能电路模块化思想，研究了电光混合系统超混沌的控制与同步，并对其在保密通信中的应用进行了实验研究。
Digital control has been becoming one direction of modern power electronics development . first , three modes of spwm modulation were introduced in the paper , including bi - polarity spwm modulation , uni - polarity spwm modulation and double - frequency uni - polarity spwm modulation . after comparing , double - frequency uni - polarity spwm modulation is used in the paper 首先,本文介绍了三种经典的spwm调制方式,包括双极性spwm调制法,单极性spwm调制法,倍频单极性spwm调制法,通过比较最终选择了倍频单极性spwm调制法作为本文所研究逆变器的调制方式。
Researches the basis watermark managing works particularly and systemly . there are many works to do on watermak technology except watermark embedding and extraction arithmetics such as the watermark choosing , encoding , modulating , demodulating and the watermark capacity . these prior and ultimate works ensure that the arithmetic is brought into effect . just understanding these , this paper analyses and researches the basic watermark theoretics in many pages . it brings forward chaos modulation on watermark modulating , brings forward chaos permuting on image permuting , introduces bch encoding on letter watermark processing and discusses the approximate estimate of the watermark capacity in dct domain and dwt domain by applying the current communication theoretics . there works not only extend ways for the later work but also are significative on watermark research 全面系统地研究了水印信号的处理技术数字水印技术除了水印嵌入和提取的算法外，还有许多工作需要做，如水印的选码、编码、调制、解调、能量的确定等等，这些预处理和后处理工作是算法有效实施的必要保证，正是基于这样的认识，本文利用较大的篇幅对水印的基本理论知识进行了详细的分析和研究，在水印的调制方面，提出了混沌调制法；在图像水印的置乱方面，提出了混沌置乱法；在文字水印的处理上，引入了bch编码；在水印容量分析方面，结合现代通信理论，对图像在dct域和小波域内的水印容量估算进行了详细的探讨，这些工作不仅为本文后期工作铺平了道路，而且对数字水印的研究具有重要的意义。
According to the following design theory : the dsp calculates in real time and produces three phases spwm waves to control the on or off of the 6 igbts in ipm respectively . ipm then inverts the commutated single phase direct current ( insulated gate bipolar transistor ) into three phases alternating current . when modulated signals of spwm are changed , the on - off time of switches also changes , so as to the voltage and frequency of output signals 本文提出了一种基于dsp (数字信号处理器tms320f240 )的通用的三相间接变频电源系统，利用分段同步调制法和混合查表法，实时计算不同频率下的采样周期、电压幅值、输出脉宽，产生双极性spwm波形，经驱动放大后用于ipm ( intelligentpowermodule )中的绝缘栅双极型晶体管栅级驱动，以控制电源的输出电压和频率，实现变频电源的智能数字控制。
One is this definition has constructed the economic regulation law system from six different analysis angles of view : ( 1 ) macroeconomic regulation law and microeconomic regulation law ; ( 2 ) economic regulation subject law / construction law and economic regulation behavior law ; ( 3 ) economic regulation law in the national spirit of the law righteousness and economic regulation law in the non - national spirit of the law righteousness ; ( 4 ) economic regulation law in the organization malfunction significance and economic regulation law in the organization limit significance ; ( 5 ) ancient economic regulation law , modern economic regulation law and future economic regulation law ; ( 6 ) economic regulation law of market failures , economic regulation law of state failures and economic regulation law of the third department failures 一是该定义从六个不同的分析视角构筑了经济调制法的体系： （ 1 ）宏观经济调控法与微观经济规制法； （ 2 ）经济调制主体法与经济调制行为法； （ 3 ）国家法意义上的经济调制法与非国家法意义上的经济调制法； （ 4 ）组织失灵意义上的经济调制法与组织局限意义上的经济调制法； （ 5 ）古代经济调制法、现代经济调制法与未来经济调制法； （ 6 ）市场失败性经济调制法、国家失败性经济调制法与第三部门失败性经济调制法。
Secondly , the chaos and hyperchaos of drefl is successfully controlled by three methods - period - parameter - modulation , delay nonlinear - feedback parameter - modulation and outer - period - signal - drive . the latter two methods are new methods that we present based on original methods for control chaos and considering the character of drefl , the results of controlling the chaos and hyperchaos of drefl is satisfying 其中，非线性延时反馈参数调制法和外部周期信号驱动法是我们在已有的控制混沌的基础上，并结合双环掺铒光纤激光器的自身特点而提出的两种新方法，这两种方法的控制效果是令人满意的。
