布尔逻辑

We use a "complete Boolean logic" system.

我们使用了"完整的布尔逻辑"的制度。

A new method based on Boolean logic operation is proposed for test selection in this paper.

This is due to the limitations of the attribute--you can't perform boolean logic.

这是由于在限制属性-您不能执行布尔逻辑。

The pneumatic logic is simple Boolean logic based on the sign of the position error.

气动力学的逻辑是简单的布尔逻辑根据位置误差的标志。

An interesting application of set cover is Boolean logic minimization.

There are a couple of things you should definitely be aware of: you should understand how to represent numbers in different bases and how to manipulate boolean expressions using boolean logic.

有几件事情是你必须做到的：你要清楚怎样用不同的进制表示一个数，还要知道如何用布尔逻辑计算布尔表达式。

This passage analyzes the advantage and disadvantage of the Boolean Model and the Vector Space Model in information retrieval model: the Boolean Model is simple to realize, but its classification ability is limited and the logic expression formula is strict.

本文分析了信息检索中传统文档特征表示的布尔逻辑模型和向量空间模型的优缺点：布尔逻辑模型虽机制简单、容易实现，但是它的分类能力有限且逻辑表达式过于严格；向量空间模型将文档映射到连续域向量空间，为进一步的权重计算等多元处理提供了基础，但容易忽略文档集合中各个文档的一些共有特征。

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。

NAND gate 403 is a logic gate that performs a NAND Boolean logic function on the UP and DN signals to generate a voltage signal VIN.

NAND门403是对UP和DN信号执行NAND布尔逻辑功能以生成电压信号VIN的逻辑门。

Optical logic devices, especially the multiple-valued, threshold and fuzzy logic devices which are more powerful than the binary logic gates, are key elements in the optical computing systems.

光学逻辑元件，特别是在功能上高于二进制布尔逻辑的多值逻辑、阈值逻辑和模糊逻辑元件是光计算系统中不可缺少的关键元件。
