Relationship between DNA content and evolutionary degree DNA contents of bivalves were analyzed statistically with SPSS software at subclass, order, family and species grade respectively. Significant difference was detected between mean values of two subclasses according to the result of T-test. The DNA content of Heterodonta (3.77pg) was distinctly larger than that of Pteriomorphia (3.14pg). It was concluded based on ANOVA that the general trend of DNA content was to change from lower to higher values associated with evolution at higher taxonomical classification, i.e.
核DNA含量与进化地位的关系运用SPSS统计软件,在亚纲、目、科以及种4个分类等级上对双壳贝类的核DNA含量进行了统计分析。T检验结果显示,两亚纲核DNA含量的平均值有明显差异,异齿亚纲的核DNA含量平均值(3.77pg)显著大于翼形亚纲(3.14pg),该结果表明,核DNA含量在较高的分类等级,即亚纲上表现出随着进化地位的升高显著增大的趋势。

As feature extraction acts an important role in pattern recognition system, we propose three novel feature extraction methods for HCCR: a、Two structural feature extraction methods, Stroke Cross Counting Features and Peripheral Features are studied. According to the characteristics of Chinese handwriting samples, we extend the SCCF and PF respectively to weighted elastic SCCF and weighted elastic PF. Experiments show that the modified feature extraction approaches are better than original approaches. b、A new statistical feature extraction method——Elastic Meshing Directional Decomposition Feature extraction is proposed. According to the stroke statistical properties of Chinese character, we first decompose a handwritten character pattern into four directional subpatterns. Then a set of elastic meshes are applied to each of the four subpatterns respectively to extract the pixel distribution features.
统计识别方法:利用统计模式识别的经典方法——Bayes分类方法来进行汉字识别的研究,特征提取是统计模式识别的关键,本文着重围绕手写体汉字的特征分析和提取方法进行了研究,提出了三种特征提取的新方法: a、两种改进的结构特征提取方法:在笔划密度特征和外围特征的基础上,结合手写体汉字的特点,提出了加权非均匀笔划密度特征、加权非均匀外围特征的特征提取新方案; b、一种新的统计特征提取方法——弹性网格方向分解特征,根据汉字方块字的特点及笔划分布的统计特征,对手写体汉字进行横竖撇捺四方向的分解,并利用一系列的弹性网格对汉字分解后各分量的象素进行统计而提取特征,实验证明该特征提取方法用来进行手写体汉字识别是十分可行和有效的。

In this paper, we propose a new approach to spoken Chinese understanding which combines statistical and rule-based methods. In this approach, the semantic classification trees which are built by the semantic rules automatically learned from the training data are used to disambiguate key words related to the sentences' shallow semantic meaning, and then, a statistical model is used to extract the whole sentence's domain action.
本文面向口语自动翻译提出了一种统计和规则相结合的汉语口语理解方法,该方法利用统计方法从训练语料中自动获取语义规则,生成语义分类树,然后利用语义分类树对待解析的汉语句子中与句子浅层语义密切相关的词语进行解析,最后再利用统计理解模型对各个词语的解析结果进行组合,从而获得整个句子的浅层语义领域行为。
