非数字的

A second complication arising from the merger is that the 1977 figures shown in this report are different from the 1977 figures shown in the report we mailed to you last year. Accounting convention requires that when two entities such as Diversified and Berkshire are merged, all financial data subsequently must be presented as if the companies had been merged at the time they were formed rather than just recently. So the enclosed financial statements, in effect, pretend that in 1977 the Diversified-Berkshire merger already had taken place, even though the actual merger date was December 30, 1978. This shifting base makes comparative commentary confusing and, from time to time in our narrative report, we will talk of figures and performance for Berkshire shareholders as historically reported to you rather than as restated after the Diversified merger.

合并案所引发的第二项影响则是今年报表中秀出1977年的数字与去年提供给各位同一年度的数字有所不同，会计原则要求当像多元零售与伯克希尔这样二个独立个体合并时，所有报告的财务数字都必须假设这两家公司原本就在一起，所以后续呈现所有数字，是假设这两家公司早在1977年就已经合并，虽然真正合并的日期是1978年的12月30日，这样的改变使得比较性的评论很容易产生混淆，因为以往的报告中，我们告诉各位的都是伯克希尔的历史记录，而非依照合并多元零售后重新修正数字。

As soon as you use a number, that feels all precise, like a code of laws or something, and players only see the number, not the philosophy behind it.

一旦你使用了数字，这让人觉得很精确。就像法典或者其他什么。玩家也只关注数字，而非它背后的哲学。

D Match any decimal digit, same as [0-9] \D is inverse of \d: do not match any numeric digit

d 匹配任何数字，和 [0-9] 一样 \D 是 \d 的反义：非任何数字

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。

For preparing for the researches of text digital watermarking and advantaging other researchers" development when using the Chinese mathematical expression theory, this paper designs and realizes a development platform of Chinese mathematical expression. It has been proved by experiments that the platform"s function, execution speed and stability can satisfy the requirements of conversion and operation of enormous data.This research found out that the structure information of Chinese have plenty redundant information that can be used by the Chinese mathematical expression for the digital watermarking, the data embedded can possess better robustness. Based on this finding, this paper designs a kind of text digital watermarking method of embedding watermarking by using Chinese structure, and realizes the method by using the Chinese mathematical expression platform.Considering the watermarking embedding algorithms importance to the robustness of the text digital watermarking, this paper makes fully use of the advantage of the Chinese mathematical expression theory to design a kind of layered text method, which has being realized by using the Chinese mathematical expression platform. The layered text method can handle the text as a solid structure, and the embedding data havepreferable robustness.Finally, based on the researches of the text digital watermarking method and the text layered method, this paper integrates the method of making use of the Chinese structure embedding watermarking with the robust algorithm based on text layered, and realizes a brand-new text digital watermarking method. Proved by lots of experiments, this brand-new method has good robustness and better invisibility.

With the development of computer and network technology, there are more and more applications of digital contents which are easy to be copied, modified and spread. Because of these features, the digital contents are also always under the risk to be filched, juggled, accessed without authorization and illegally distributed. The digital contents can hardly be protected effectively in the network environment due to its large-scale disordered distribution, which has hindered the development of the applications based on the digital contents.

随着计算机技术和网络技术的发展，具有易复制、易修改和易传播特征的数字内容的各种应用蓬勃兴起，但这些特性同时是一把双刃剑，使得数字内容在其生命周期内随时面临被窃取、篡改、非授权访问和非授权分发的威胁，造成数字内容价值的降低甚而丧失，这直接或间接地制约着各种数字内容应用的发展。
