有符号的

Most people consider the return current when considering a fully differential circuit, but when considering the more usual circuit where a signal is referred to 'ground' it is common to assume that all the points on the circuit diagram where the ground symbol is to be found are at the same potential.

分析差分电路时，绝大多数工程师都会注意到返回电流，但对于常见的所谓单端电路，即所有信号采用相同参考点的电路，往往会认为电路中所有标有参考点符号的地方电平都相等。

Besides, through the study of essentially bounded functions on the unit circle, we get the necessary and sufficient conditions for the essential commutativity of k~-order slant Toeplitz operators with special symbols.

在此基础上，通过对单位圆周T上本性有界函数性质的研究，给出了以特殊函数为符号的两个k阶斜Toeplitz算子本性可交换的充要条件。

Much more convincingly than any comparable real image, they function as a collective symbol and – in a vampiristic act of the invented image against reality – take its place.

甚至比真实的图像更具有说服力。它们担当了集体符号的角色并在采用人工图像取代真实这样一个诡异的行为中发挥着独特的作用。

Connectionist, constructionist and behaviorist cognitive psychology are new approaches, which have been developed from symbolist cognitive psychology. They have some relations and similarities, as well as differences.

联结主义、建构主义和行为范式认知心理学是在符号主义认知心理学的基础上发展起来的认知心理学新取向，它们之间既存在着一定的联系和相同点，也有一定的差异。

Symbolic link is useful when you have a lot of folders and files are scattered all over the directory tree, and you need to manage them from a single location.

符号链接是有用的当您有很多的文件夹和文件，分散在各地的目录树，并且您需要管理，他们从一个单一的位置。

Applying this transformation once, we can make the degree of the first r rows of the polyphase matrix decrease one order, and avoid decreasing the degree row by row as the traditional methods. This method is not restricted by the length of the filter, and needn't factorize the polyphase matrix into a special form.

本文对紧支撑小波构造方面的一些问题进行了探讨和研究，得到一系列有意义的结果，主要包括：在一元小波构造方面，给出由m-带紧支撑正交插值尺度函数显式构造相应正交小波符号函数的公式，这部分内容在第2章中给出。

The main works are introduced as follows. At first, we propose an algorithm to decompose the fixed point signed multiplicator into two sub-components with minimal nonzero digitals, which reduces the number of partial products potentially.

基于上述考虑，本文主要开展了关于乘法器算法优化及含有乘法器的FIR数字滤波器结构优化的研究，具体包括以下几方面的工作：(1)本文提出一种有符号定点乘数的分解算法。

DunHuang documents is a valuable information source. It accumulates, exchanges and spreads the cultural information effectively by symbols and carriers on time and space. Furthermore, the discovery of the old newspaper DunHuangJinZouYuanZhuang provides the oldest newspaper's authentic proof for the spreading history of news. So, its value is not to be sneezed at.

由于敦煌文献本身非常有效地在时间上、空间上用符号和载体积累、交流并传播着文化信息，是一种极有价值的信息源；同时敦煌进奏院状的发现又为新闻传播史提供了最早的报纸实证，因而它在传播学方面的价值也非同一般，不容忽视。

All the physical properties should be identical except for the optical rotations of the two isomers, which are of opposite sign.

这两个异构体除了旋光度有相反的符号之外，其他所有的物理性质都应该是完全相同的。
