A methodology of noise-like key generation is presented. Chaotic process of tentmap function is used as a deterministic generation of noise-like key, image storage and retrieval are completed in a algebraic form. A mathematics model of noise-like chaotic coding memory is constructed, meanwhile the basic mechanism of circulant convolution and circulant correlation in image information storage and retrieval are demonstrated.

在详细阐明数字序列和字母序列的1-D映射函数设计方法的基础上，利用构造出的1-D映射的稳定周期环和不稳定极限环完成了存储和联想记忆功能，为了识别有关的输入信息，提出了映射函数直接控制的方法；在此基础上，提出了一种1-D映射型混沌神经网络模型，该网络本身不当作一个"黑箱"处理，网络的参数值由网络中实现的映射函数来确定，该网络模型具有联想记忆、容错性、模式识别和奇异滤波等一系列智能信息处理的基本功能。

A-Za-z\w+ means the first character should be alphabetic, i.e., either A–Z or a–z, followed by at least one alphanumeric character.

A-Za-z\w+的含义是：第一个字符是字母，即，由大写字母A到Z或是小写字母a到z组成，它后面至少跟有一个由字母或数字组成的字符。

To compact data by combining parts of the data, for example, to transform a two word alphabetic key into a oneword numeric key by adding the numeric equivalents of the letters.

通过将数据的某些部分进行组合来压缩数据，例如，通过将一些字母的数字等值相加，可把两个字长的字母键词变换为一个字长的数字键词。

CI is 101; IC is not even a valid Roman numeral (because you can't subtract 1 directly from 100; you would need to write it as XCIX,"10 less than 100, then 1 less than 10").

CI 表示 101；而IC 甚至不是一个合法的罗马字母（因为你不能直接从数字100减去1；比需要写成XCIX，意思是比100 小10，然后加上数字9，也就是比 10小1的数字。

Firstly, the system is divided into four sub systems: Chinese characters recognition system, character recognition system, recognition system including characters and digits, and digital recognition system; Secondly, the statistic information about left scan line free length of every character is used as a group feature of car plate, which will accomplish the recognition together with statistic template by weighted sum.

首先将车牌字符识别分成四个子识别系统——汉字识别系统、字母识别系统、字母和数字混和识别系统，以及数字识别系统；然后选择各字符的左扫描线空程长度统计信息作为车牌字符的一组特征，与统计模板进行加权组合，来共同完成车牌字符的识别工作。

Set up password, ordinary people from the habit of the order of the smaller a, b, c, d or 1,2,3 started this just to meet the violence of the crack to break the order, because they are in accordance with the nature of letters and numbers Sort calculation.

设置密码时，普通人的习惯都是从顺序较小的a、b、c、d或者1、2、3开始，这一点刚好满足了暴力破解的破解顺序，因为它们就是按照字母和数字的自然排序进行计算。

Genes that are numbered are essential: a mutation in any one of these loci prevents successful completion of the lytic cycle.

标有数字的基因是必须的，用三个字母缩写表示的基因在通常的感染条件下可认为是非必须的。

For example, special exercises can increase streng th in the hands and improve muscle memory.

例如，专门的联系可以增强手部的力量并且提高肌肉的记忆能力。这是锻炼肌肉记住字母和数字的形状。

But digitalspeak is out-of-line numbers and letters, including the number 0 ~ 9, A ~ Z letter directly to the naked eye, it is generally recognized from 8 ~ 16-bit, the number of bits different code system.

而数字标记是在线条边的数字和字母，包含0~9数字，A~Z字母，可间接为肉眼所辨别，凡是从8~16位，码制差别位数也不差别。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
