识别符号

In employing the Communist symbol of the hammer and sickle, Tools touches upon people's profound familiarity with these images, thus effectively converting the found tools into something greater.

工具》利用共产主义运动中的镰刀和锤子的符号，在人们记忆中形成形象识别的通俗和熟识性，而把现成物的镰刀和锤子转换出来了。

Secondly, what Glossematical School wants is to establish the linguistic typology, namely metatheory, helping to compare different theoretical pattern, sign systems, linguistic signs, and levels of linguistic symbol theoretical pattern, on the basis of which the study objects of glossematics are finite as relation among the previous statement, defined as function.

因为语言符号的形式和意义之间的关系是任意性的，不存在普遍意义的范畴。语言学的所有范畴都要从具体语篇中演算出来，这就要建立语言代数学，即语符学。其二是用纯理语言构建的语言模型，必须拿具体的语言去检验。模型反映出的是人类所有语篇，包括未出现的和已经消亡的语篇的各种可能性，利用语符学的经验原则和推导条件帮助识别出哪些是现实中存在的形式，哪些是潜在的形式。

Mainly discussed here are the method of locating superscripts and subscripts, the LL(1) grammar structure of mathematical expressions, and the structure analyzer. The recognition process is briefly described using neural networks.

重点介绍了上下标的定位、基于LL(1)文法的表达式构成规则和公式结构分析器的设计，并简略介绍了基于神经网络的数学符号识别方法。

The scanners regularly encounter difficult words (those for which two different character-recognition algorithms produce different transliterations).

扫描设备经常遇到难词（两种不同的符号识别程序会将其显示成不同的字母）。

China's plan to cut energy intensity by 20 percent and pollutant discharges by 10 percent between 2006 and 2010 is a case in point.

中国计划在2006年到2010间降低20%的能源强度和减少10%的主要污染物排放，就是一个这样的例子。
