For example, the object is composed of four blocks, i.e. block A, B, C, D. Block A locates the left of block B and above block C. According to order, its code is ABDC etc. This code does not change its order after the object rotates, zoom, downsizes. The disadvantage of this method is that it will lose the target when the color is changed.A video fluid is composed of compressed data which include I, P and B(bi-prediction) frame. The data of each block of P frame is predicted by motion prediction and compensation from the data and motion vector of I frame.

MPEG视频流由I、P、B组成，为减少空间、时间的冗余，P帧的数据来自已经解压缩的I帧和P帧，B帧的数据来自已经解压缩的I帧和P帧或者P帧和P帧，这些需要解码的图像通过运动预测和补偿对P帧／B帧进行解码，P帧／B帧中每一个宏块的数据来自于最佳匹配的相应I帧和P帧或者P帧和P帧中，以及图像变化而必须的运动补偿。

After encapsulating the code into OCX, the efficiency of application development and re-use of code is improved.

使用Windows的ActiveX技术，把网关的功能实现封装在OCX控件中，提高了软件代码的可重用性和开发效率。

To prevent from error in correcting, CRC code and hamming code are used in the method.

为了防止误纠错，采用了CRC检验与纠错相结合的方法。

So we revisited the verification code once more, and found out that the code spends most of the time in a function that is responsible for the calculation of SHA-1 hashes.

因此，我们重新再一次的验证码，并发现该代码花费大部分的一个函数，是为的SHA - 1哈希负责计算时间。

Indent Code - Indents your code to a generally accepted style.

缩进代码-缩进您的代码以一种普遍接受的风格。

A Bar Code Chinese Character Inputting System has been established according to the National Standard Code of Chinese Characters.

条形码汉字输入系统是依据汉字的国标码设计的，与一般的整字输入方法相比，有很多优点。

These types of modifications are called source code instrumentation, and various tools use instrumentation for purposes such as determining test coverage, measuring performance bottlenecks, etc. In our case, we will be instrumenting the source code to make the stack dump more readable.

这些类型的修改源代码被称为仪器，以及各种工具的使用用途，如确定测试覆盖仪器，测量性能瓶颈等，在我们的情况，我们将插装源代码以使堆栈转储更具可读性。

And the basic principles of coding and decoding of Turbo Codes are discussed, the MAP and Max-Log-MAP algorithms which are suitable for the Turbo Code are detailedly discussed. Then, because the interleaves technology has important influence in radio channel, the article provides the detailed scheme of implementation in WCDMA system. Besides providing a series of simulation illuminates the influence of interleave-length to the Turbo-code performance.

由于交织技术是为了抵抗无线信道的噪声以及衰落的影响而采取的时间分集技术，在WCDMA的编码过程中具有重要的作用，所以本文对交织技术在WCDMA系统中的应用也做了详细介绍，并且通过仿真说明了交织长度对Turbo码性能的影响。

cyclic redundancy check code is a very important cyclic code,the coding and decoding methods are simple,easy to realize.it is strong to detect error,the probability of misjudging is nearly zero.it is a method with extremely high efficiency in controlling errors,which can fulfill the requirement of reliable information transmission in communication systems.it has got very extensive application in observing and controlling and data communication.this paper introduces the encoding and decoding principle of crc in detail,analyzes the feasibility of crc by dsp,and gives out the design proposal and flow chart according to the principle,which is very useful in applications.

摘 要：循环冗余校验码是一种重要的循环码，编码和解码方法简单，容易实现，检错能力强，误判概率几乎为零，是一种效率极高的差错控制方法，可以满足通信系统可靠传送信息的要求，在测控及数据通信中得到了非常广泛的应用。详细介绍了循环冗余校验的编解码原理，分析了用dsp实现crc的合理性，最后给出了根据校验原理实现的设计思想及流程图，具有一定的实用价值。

Pachomius manual labour was organized as an essential part of the monastic life; and since it is a principle of the monks as distinguished from the mendicants, that the body shall be self-supporting, external work of one sort or another has been an inevitable part of the life ever since.

根据圣pachomius体力劳动组织作为一个重要组成部分寺院生活；以来，这是一个原则的和尚，作为有别于乞丐，该机构应自支撑，对外工作的这种或那种已一个必然的一部分，生活至今。

In order to study the effects of parametrical rolling on the ship movement and tilts, in allusion to ship's navigating in regular following waves, the equation of ship rolling motion is transformed into normal Mathieu equation by proper variable replacement when strong parametrical excitation in restoring moment varied according to sine or cosine wave.
