Every research result shows that Bayesian Classifier acts as one important class technology, Compared with Decision Tree Construction and Neural Network Classifier, Bayesian Classifier can adequately bring into play its incertitude discursion ability, so it can ameliorate learning ability and increase accuracy of forecast, it have better class effect in some conditions.
各种研究结果表明:贝叶斯分类作为数据挖掘中一项重要的分类技术,与决策树和神经网络分类器相比,贝叶斯网络分类器可以充分发挥它的不确定性推理能力,从而改善学习效果,提高预测准确率,在某些情况下具有更好的分类效果。

By Llibre's algebraic invariant theory, at first on the basis of classification for quadric and quadric homogeneous binary polynomial, the plane linear and cubic homogeneous polynomial differential systems are classified.
利用Llibre的代数不变式理论,首先由二元二次和二元四次多项式的分类结果,对一次和三次齐次多项式微分系统进行代数分类,同时补充了已有结果中出现的漏洞;其次,由称共变张量空间的性质,对缺二次项的三次微分系统在保证轨线走向不变的前提下进行代数分类,使分类后同类系统的示性多项式有相同零点;最后通过讨论一类简单系统的有界性说明了分类的方便方处。

Videlicet, this sequence represents the accountability of the 11 features in distinguishing insects on the level of species. According to the above results, some features varies not remarkably on all levels, such as Lobation, Shape-Parameter etc. This shows that such kind of features are nearly same in all species of insects, and can represent the feature suitable to distinguish all insects from other classes of animals. On the other hand, they are not suitable as distinguishable features of levels which lower than insect Class.
从结果可以看出,有些特征在各个分类阶元上差异均不是很显著,如叶状性、形状参数,说明此类特征在昆虫中具有较强的共性,可以代表整体昆虫的特征,而不适合于作昆虫纲下阶元的分类特征;有些特征在各分类阶元下的差异始终比较显著,如周长、面积等,说明这些特征适合在各分类阶元上作为昆虫的分类特征。

But this way there is still some problems: The first is the classification of garbage awareness is not strong, looks like a trash can in fact classified and former effect is the same; second, the boundaries of recyclable and non-recovery is unknown, some of the more a strict classification is not as familiar to the students; third is the credibility of recovered, often encounter such a situation, was classified as environmental protection staff in clearing rubbish is often peremptorily, when the inverted together, it will not be garbage separation effect.
但这样的方式还是存在一定的问题:第一是垃圾的分类意识不强,看似分类的垃圾桶事实上和以前的效果是一样的;第二是可回收和不可回收的界限不明,一些较为严格的分类并非为同学们所熟悉;第三是回收的可信度,常常会遇到这样的情况,被分类的垃圾在环保人员清理的时候往往是一股脑的倒在一起,根本起不了垃圾分类的效果。

For organizing vegetation submodel, started with the bottom-up gateway to agglomerate plot-data. The vegetation types must be confirmed before predictive vegetation mapping, therefore designed a transforming program to combine 585 plot-data from different surveys for the purpose. But the result of the classification and ordination of the combined plot-data couldn't display comprehensive vegetation types of Taiwan, because the plots were insufficient and disproportionate. Consequently, this study adopted the top-down gateway to divisive vegetation. After referring to Taiwan and east-Asia vegetation research papers and American national vegetation classification system etc., the physiognomic classification scheme of Taiwan had been drafted as vegetation submodel. The scheme included 4 levels: 2 classes, 5subclasses (subarctic, coldtemperate, cooltemperate, warmtemperate, subtropical), 8 groups (based on phenology and types of predominant leaf) and 16 formations (based on moisture regime and predominant taxa). And, the scheme dealt completely with the diverse nomenclatures of vegetation types in the past.
为建立植群亚模型,首先依「整合大量样区资料,由下而上的低阶植相聚类」之途径,设计建档程序及转档程式,成功整并不同来源之585个样区资料,但因样区数目不足且分布不均,分析结果未能显示出台湾完整的植群类型;故转循「预先设定植群类型,由上而下的高阶形相分类」之途径,经参考他国植群分类系统及台湾、东亚植群分类研究报告,订定分类原则及架构,提出4阶层之潜在植群形相分类方案:(1)寒原、森林2类群系纲;(2)亚寒带、冷温带、凉温带、暖温带、亚热带5类群系亚纲;(3) 8类群系组表徵优势植群之叶片的物候与形态;(4) 16类群系说明其水分境制及优势分类群;此方案统一处理了过去各种有关植群划分之纷岐名制,方案之各阶植群类型亦即本研究之植群亚模型。

It is necessary to find a new method for garbage disposal. Compared to existent methods, landfill method of garbage block has its characters, which includes classification throwing, collection and predispose of garbage that make garbage disposal classification; use of reclaimable street collection that make garbage disposal resource; shatter,dehydration and press packing of garbage street collection that make garbage disposal decrease; disinfection and classification stack that attribute to classification administer and supervise of garbage field and make garbage disposal harmlessness; recycle, compost, burning and landfill that make garbage disposal synthesis; exploitation and use of garbage field that make garbage disposal environmental protection.
与已有的垃圾处理方法比较,垃圾块体填埋法有自己的特点,以社区为单元的垃圾源头分类投放、收集和预处理,能使垃圾实现分类化处理;通过垃圾中可回收废物的回收利用,能使垃圾最大限度资源化;通过垃圾分类粉碎、脱水、压缩成块体,使垃圾有效地减量化;经过消毒、分类堆砌有助于垃圾填埋场地的分类管理和安全监控,使垃圾处理基本无害化;回收、堆肥、焚烧、填埋,使垃圾处理综合化;填埋场的复垦与开发利用,使垃圾处理环保化。
