Actually the kernel design in the recognition method based on discrete time - frequency representation is a problem of feature selection from the ambiguity functions to reduce feature dimension.
基于离散时频分布的信号识别方法，将时频核设计问题转化为以信号自模糊函数为原始特征的特征选择问题，以实现特征降维和信号识别。
Yet, as the commission points out, the job still "combines the functions of a judge with those of an investigator" and as such operates with "fundamental ambiguity".
然而，正如委员会所指出的：这种工作方式仍然“结合了调查法官的功能”，就其本身而言，其运作“根本上是模棱两可的”。
One way to ease the possible pain of predicate ambiguity is by breaking down applications of conditions into separate generic functions.
用来降低可能出现的断言模糊性的一种方法是将应用程序的条件分解为单独的通用函数。
PEAK only complains when a particular call creates ambiguity, not when the potentially ambiguous functions are defined.
PEAK只会在碰到会产生模糊性的调用时进行抱怨，而在可能定义一些模糊函数时却不会产生抱怨。
English news items are cited to explore the pragmatic functions of the passive voice: foregrounding and backgrounding, hinting, evasion and ambiguity.
通过对英语新闻的实例分析，本文探索了被动态的几种语用功能，即削弱和突出、暗示、避嫌及歧义。
It is generally believed that ambiguity can be an obstacle to communication. But if ambiguity is used cleverly, it can perform useful functions and achieve some communication goal.
一般认为歧义会有碍交流，但如果人们加以巧妙运用，却也能起到积极的作用，更好地达到某一交际目的。
For enhancing performances and increasing functions of PD radar, High PRF, medium PRF and low PRF are commonly applied into system ambiguity appeared in range and velocity in some PRF.
为了提高检测性能和实现多功能，PD雷达常采用高、中、低脉冲重复频率prf。对应一定的脉冲重复频率，PRF会出现测距模糊、测速模糊。
