In part one (chapter 2-3), two new methods and systems of optical parallel logic operation are studied. Triple-in Double-out shadow-casting logic operation system is proposed and realized for the first time. Based on this, optical full adder and 3-bit decoder array logic have been obtained. It is the first time to use coding pattern and different reading-writing model to realize BSO-PROM optical parallel logic operation where the time-order operation is avoided, so that the computing speed of optical parallel logic gate which uses this kind of spatial light modulator is increased, and it is successfully used in optical symbolic substitution .

在第一部分，对两种新的并行光学布尔逻辑运算方法及系统进行了研究：首次提出并实现了三输入、双输出铸影光学逻辑运算系统及其由此得到的光学全加器，并提出一种以此为基础的3-比特译码器阵列逻辑，首次利用图形编码和不同的读写模式实现了无时序操作的BSO-PROM光并行逻辑运算，大大提高了这种空间光调制器用作光并行逻辑门的运算速度，使之成功地用于光学符号代换之中。

Before visual information creation,the concepts of information transmission and reception,of information symbol coding and decoding,of communication and communicating intermedium should be understood clearly.

在进行视觉信息的创造时，首先要了解信息的传送和接收过程、信息符号的编码和解码、传播及传播媒介等。

In this paper, the influence of error propagation on soft demodulation in coded MIMO system is analyzed in detail. Besides, based on the thought of soft symbol interference cancellation, Iterative Channel Soft Information for coded MIMO system is further deduced and proved to have the same form as the inverse of row norm of Moore-Penrose inverse of channel matrix.

摘要该文针对编码MIMO系统，分析了MIMO检测过程中串行干扰删除引入的误差传播对软解调的影响，同时，借鉴软符号干扰消除的思想，推导出该系统中迭代信道软信息(Iterative Channel Soft Information， ICSI)的计算方法，并证明了该信道软信息等价于信道矩阵广义逆的行范数的倒数。

The encoding between numbers and human-readable symbols is ISO646/IRV within the range from 32 to 126.

在数字和人类可读的符号之间的编码是在 32 到 126 范围的 ISO646/IRV。

What's more, we also study some key techniques and realization difficulties of image authentication in-depth, including referent block to help tamper localizing, sign bit adjustment for binary encoding, mean quantization improvement, diagonally extension to help tamper localizing, and discard isolated error point to tolerate incidental distortion. These techniques can be used for good reference to the development of image authentication technique.

此外，我们还对数字图像鉴别的一些关键技术和实现难点进行了深入研究，主要包括有：参考点辅助定位技术、二值编码中的符号处理技术、均值量化方法的改进技术、对角扩展和去除孤立点技术等，这些技术的研究都对数字图像鉴别技术的发展具有很好的借鉴意义。

Like musical notation , modern mathematical notation has a strict syntax and encodes information that would be difficult to write in any other way.

像乐谱，现代数学符号有严格的语法和编码信息，将是困难的收件以任何其他方式。

In the 1940s,researchers simplified the programming process by developing notational systems by which instruction could be represented in mnemonic rather than numeric form.

在40 年代，编程研究员开发了一种能简化编程过程的系统，它用符号体系来存储程序，而不用数字编码存储。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".
