The article takes balancing all quarter copyright benefit as discussion entrance, analyses the questions of copyright benefit management, and proposes strategies to constructing benefit management mechanism of the digital copyright public interests management and the copyrighter抯 interests. In the end, the author thinks we should construct a kind of digital copyright benefit management mechanism which regards policy as a guide, takes the law as criterion, regards protection as the means, and takes utilization as goal, based on interests equilibrium. The management mechanism will stimulate creation, maintain interests fair, advance resources utilization, and promote culture art thriving.

文章以平衡各方利益为切入点，在分析当前数字版权利益管理中存在的问题的基础上，从数字版权的公众利益管理和数字版权人利益管理两方面入手，详细分析了各自管理机制构建策略，认为数字版权领域里应该构建一种以政策为先导、以法律为准绳、以利益平衡为基础、以合理保护为手段、以利用为目标的刺激创作、维护公平、推进共享、促进文化科学艺术繁荣的公众利益与私人利益和平共处的管理机制。

In this dissertation, digital lock-in detection techniques under integer period sampling and non-integer period sampling are separately investigated (1) Under integer period sampling, digital signal sequence is acquired through sampling the measured signal, but digital reference sequence is acquired through mathematical operation, then digital lock-in detection can be realized by calculating crosscorrelation function of digital signal sequence and digital reference sequence Harmonic measure is also analyzed, and a method of measuring harmonic of a periodic signal under aliasing is put forward.

本文对使用采样ADC把模拟信号转换为数字信号并通过计算数字信号的相关函数来实现锁定检测的技术进行了研究，在此基础上设计了一个多功能的数字LIA并在一些科学实验中进行了应用。本文对整周期采样和非整周期采样时的数字锁定检测技术分别进行了研究。(1)在整周期采样时，对被测信号进行采样得到信号序列，而参考序列由数学运算得到，通过计算信号序列和参考序列的互相关函数就可实现锁定检测。

First, let's consider the number seven: In mathematical terms, it is an irrational number, i.e., a number that cannot be represented as a simple fraction, a number that is "uncountable." To the mind of the symbolic thinker, the number is associated with all that is strange and unusual.

首先，让我们认识一下数字7；在数学上，它是一个无理数，也即除以它的结果不能得到一个单一的数字，除以这一数字将得到一个无穷数列，对一个符号象征思想家的内心来说，这个数字会让人联想到所有古怪的，不寻常的事物。

We open the C disk access disk C, and these are: the method in accordance with the above my computer to open a list of projects, according to the numeric keypad 4 or 6 button to switch to the 13 list, according to the number of keyboard 1 or 3 key to switch to the local disk C set the list of projects, according to slash the number of keys on the keyboard "click" options, press the Enter key numeric keypad,"Double-click" to open the C disk.

我们打开C盘查阅C盘的状态，步骤是：依照上面的方法打开我的电脑列表项目，按数字键盘的4或6键切换到13列表后，按数字键盘的1或3键切换到本地磁盘C盘列表项目，按数字键盘上的斜线键"单击"可选中，按数字键盘的回车键"双击"可打开C盘。

The main features of the system are: the communications line is not only used for data transmission but also responsible for the system control and management; only one analogue to digital converter is needed for the whole system; a digital trimmer which is analogous to the adjustable resister in function is installed to each sub—system.

本文所进行的数字型条干均匀度测试仪的系统设计，采用了多微处理器的分布式并行结构，提出了一种数字信号的总线结构，采取了数据预处理和数字微调等措施，其主要特点为：半双工异步通信线不但用于数据传输，而且还负责系统的控制和管理；整个系统只需一路模数转换器；各子系统均设有数字微调装置，其功能类似于模拟电路中的电位器，可独立进行参数调整。

Altera Corporation system to the Cyclone FPGA series of digital platform, microprocessor, bus, Digital Frequency Synthesizer, memory and I / O interface hardware concentrated in an FPGA, the use of direct digital frequency synthesis technology and digital modulation waveforms required to achieve the rise, Using FPGA ROM storage of the DDS waveform table, and make full use of on-chip resources, improve the system's accuracy, stability and robustness.

系统以 ALTERA公司的 Cyclone 系列 FPGA 为数字平台，将微处理器、总线、数字频率合成器、存储器和 I/O 接口等硬件设备集中在一片 FPGA 上，利用直接数字频率合成技术、数字调制技术实现所要求波形的产生，用 FPGA 中的 ROM 储存 DDS 所需的波形表，充分利用片上资源，提高了系统的精确度、稳定性和抗干扰性能。

The criterion and extent of copyright infringement liability of DL, on the one hand, which affect directly not only the standard and quality of copyright protection, but also the existence and development of increasing internet industry, on the other hand, which is correlative with interests of innumerous users, hence copyright must delimit and define the liability of DL .

因此，版权保护法律在界定数字图书馆责任的同时，必须考虑对其责任加以必要的限制。文章第二部分主要论述了数字图书馆信息加工、信息组织和信息传播中的知识产权问题。信息资源建设是中国数字图书馆工程的基础和核心，丰富的信息资源是数字图书馆健康发展的前提与保障。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
