位运算

The speed of a computer is affected by the number of bits it can process at once. For example, a 32- bit computer can perform arithmetic and manipulations on 32-bit numbers, whereas a 16-bit computer must break large numbers into 16-bit quantities, making it slower.

电脑的运算速度会受到它一次可以处理位元多寡的影响，例如32 位元电脑一次可以进行32 位元的运算，而16 位元的电脑因为每次只能进行16 位元的运算，所以它必须将比较大的数打散成16 位元的量，所以这样会造成速度变慢。

Experiment results show that the extended decision procedure supports most verification formulas met in slicing execution.

我们优化了判定过程，并扩充了对整数除法、取余和位运算的支持。

The algorithm is efficiently length-reduced compared with the traditional ones. It uses bitwise operation and shift logical for data substitution, and generates a length-fixed MAC.

算法通过位运算和逻辑移位进行数据替换，从而得到与验证的数据长度无关的定长MAC，有效减小了MAC的数据传输量。

But there would be a serious problem with the above definition of macro, if it is used as follows what is the problem??

这个程序多半是用来内存对齐的，所以用位运算以获得高效率

The purpose is to inspect the grade differences on time of mental addition and mental subtraction of pupils from three grades as well as grades differences of arithmetic time and integration time. The results show that mental arithmetic time of pupils from Grade 2, 4 and 6 decreases with the increase of grades.In the non-carry mental addition of 1-digit number and multi-digit number, menta...

研究结果表明，2、4、6 年级小学生口算时间随年级的增高而减少；在一位数加多位数不进位加法口算中，口算时间差异主要源于运算时间差异和整合时间差异；在一位数加多位数进位加法口算中，口算时间差异源于运算时间差异；在多位数减一位数不借位减法口算中，运算时间年级差异不显著，而整合时间存在显著的年级差异；在多位数减一位数借位减法口算中，口算时间的年级差异主要表现为运算时间的差异，而整合时间差异不显著。

In this thesis, we also formulate a general problem for rounding in the transform domain.

在此论文中，我们亦对转换域中的进位运算做一研究。

The arithmetic of the subtraction is based on the serial arithmetic. It can entirely enumerate every pair of subtrahend on a bit, and it also calculates two possible loaning carry values on each bit. So the subtraction can be operated through automatic selection, and complete collateral subtraction and carry operation. The method of single division is same to it. With the stenography of shifengshou we can solve the complex division. We put the formula and the technique into the DNA model to get the result. The methods all make the step decrease and change the conventional arithmetic.

减法的DNA 算法理论主要是来源于串行思路中的算法，它是将每一位上的两个减数对的所有可能进行全列举，同时考虑每一位上的两种借位信息，使得运算进行自动选择，一步即可得到最终结果的算法；除法中一位数除多位数的算法还是从我们平时所进行的串行运算中得到启发而设计的算法；而除法的多位计算思路则来源于史丰收速算法，将算法中的口诀及技巧应用到DNA 链当中，使得传统中的代数运算能够并行的得到最终的结果，这三种算法的设计都使得计算步骤减少，从根本上改变了算法的运算机制。

The modular design of printNet system is divided into several application part, such as data processing tools, design tools, products, Business card printing tools, and solutions to technical tools, of which the highest is a design tool over the actions that it printLayout from page formatting and setting variables, but also can be used by an operator in a transform tool programming, so that the contents of the variables in a database in output for operations, now produetion of mostly to one-dimensional bar codes and encrypted bit or anti-false, the party is a method in the bar code by addition, subtraction, multiplication, Division, opinins Mo, and so after the results or the results of data, or the result is converted to the data that corresponds to a location in one of the ntehs detection accuracy is valid, just make a bit of the inverse operation, the operation that results in comparison with the original data, such as the same as the data is valid, such as different then the data is not valid, this scenario is the most simple and most primitive anti-counterfeit. PrintNet software to complex product environment " interpuntion and output the integration of integrated management " solution possible.

printNet系统的模块式设计分为几个应用部分，如数据处理工具、设计工具、产品制卡工具以及方案解决工具，其中技术含量最高的是对设计工具printLayout的操作，它除了设计页面格式和设置变量外，还可由操作员在转换工具中编程，以便对数据库中的变量内容在输出时进行运算操作，现在生产中应用的大多是给一维条码加校验位或是防伪加密，其方一法是将条码中的数据经过加、减、乘、除、取莫等运算后，将结果或将结果中的几位至于数据后，或将结果转换成对应符号放在数据中的某个位置，如须检测某一数据是否准确有效，只要把校验位上的数进行逆运算，把运算结果与原数据比较，如相同则数据有效，如不同则数据无效，这种方案是最简单最原始的防伪加密的方法。printNet软件系统使得在复杂产品环境下的&排版与输出一体管理&的集成解决方案成为可能。

It"s revealed that the consistency probability of unsigned ones complement addition with bit-wise exclusive-OR is very greater than the ideal value 2~", though it is very small, and the consistency probability of unsigned ones complement addition with addition modulo 2 is 2/3 approximately, hence it is very large.

结论表明，进位返加运算与逐位模2加运算的相容概率尽管很小，但远大于理想值2~；进位返加运算与模2~n加运算的相容概率很大，近似为2／3。
