This paper introduces a modified fuzzy decision tree model. Firstly, the data are fuzzed by the use of optimal division point with optimal division entropy. Secondly, uncertainty theory of fuzzy math is introduced and a tree is built according to uncertainty of classification and creation rule. Finally, each unit can be detected about whether or not it is a fraud according to rule match method.

介绍了一种改进的模糊决策二叉树模型，即采用最优分割熵方法确定最优割点来对数据模糊化，引入模糊数学中的不确定性理论，依据分类的不确定性建造树，生成规则，在此基础上利用规则匹配的方法检测任意的样本数据是否为欺诈数据。

As an often used physical model with good theoretical and practical values, StreeterPhelps model has been widely used to study water quality. However, in some special water areas the utilitization of StreeterPhelps model has some limitation as confirming reaeration coefficient often comes from tests in rivers with fast water flow speed with no consideration of wave effects. Furthermore, in practical research in Three Gorges Reservoir, the changing rule of COD appears abnormally. In some water areas far from pollution source, the value of COD changes with time, but does not follow the exponential attenuation rule. This phenomenon can not be explained by former modified StreeterPhelps model.

StreeterPhelps模型是目前进行河流水质研究常用的物理模型，具有良好的理论和实用价值，然而在某些特定水域，该模型的应用受到限制，主要原因是复氧系数的取定多在水流速度较大情况下得到的，而未考虑水面波动对复氧系数的影响，另外，在实际研究过程中发现三峡库区COD变化的规律出现异常：在离排污口相当远的水域，COD随时间变化趋势并不是指数衰减，而是在某个常值附近微小摆动，以往很多修正过的StreeterPhelps模型都无法解释这个现象。

研究并设计了入侵推理和基于贝叶斯网络异常检测特征参数的学习规则、设计了贝叶斯网络的数据结构及相关算法。

Article 30 The Implementing Rule of Certification, and specific managerial provisions( including the Rule for Management of Certification Signs), shall be formulated separately by the Supervisory and Managerial Committee of Certification and Permit of the PRC.

第三十条本规定中的认证实施规则、认证标志等具体管理制度由国家认证认可监督管理委员会另行制定。

The realist in murder writes of a world in which gangsters can rule nations and almost rule cities, in which hotels and apartment houses and celebrated restaurants are owned by men who made their money out of brothels, in which a screen star can be the fingerman for a mob, and the nice man down the hall is a boss of the numbers racket; a world where a judge with a cellar full of bootleg liquor can send a man to jail for having a pint in his pocket, where the mayor of your town may have condoned murder as an instrument of moneymaking, where no man can walk down a dark street in safety because law and order are things we talk about but refrain from practising; a world where you may witness a hold-up in broad daylight and see who did it, but you will fade quickly back into the crowd rather than tell anyone, because the hold-up men may have friends with long guns, or the police may not like your testimony, and in any case the shyster for the defense will be allowed to abuse and vilify you in open court, before a jury of selected morons, without any but the most perfunctory interference from a political judge.

写谋杀小说的现实主义作家所写的世界中，歹徒可能统治国家，甚至城市。在那里，旅馆公寓、有名的酒楼餐厅的主人是靠开妓院发财的，电影明星可能是盗匪的眼线，大厅里那个彬彬有礼的人可能是彩票老板。在这个世界里，法官藏有一地窖的私酒，却可能因一个人口袋里有一瓶酒而送他进监牢；你家乡的市长可能为了到手钱财而对谋杀案眼开眼闭；入夜之后无人敢在街上行走，因为法律和治安是句空话，从来没有实行过。在这个世界里，你很可能在光天化日之下见到有人沿路拦劫，明明看清楚是谁在作案，但是你马上躲开，混到人群中去，不愿出来告发，因为拦劫的人可能有朋友为他报复，或者警方可能不喜欢你出庭作证，不管怎样，为被告辩护的恶讼师可以在法庭上对你百般侮辱，因为陪审团里都是他们挑选的低能儿。有党派背景的法官除了敷衍一下外不会加以干涉。

Determine the correct exposure time is by using the exposure slide rule, this type of slide rule on the market.

猜测不差曝平工夫的办法是搁置曝平计算尺，这类计算尺可以在阛阓上当到。

Without such detailed information, raking comes as a rescue since it requires only the knowledge of marginal distributions of selected variables. Popular as it may be, raking takes no account of associations among post-stratifying variables. Furthermore, it relies heavily on Chi-squared tests and a pre-selected p-value (usually 0.5) as the stopping rule of iteration, an ad hoc rule justified only by convenience.

因此，目前最常采用的是「反覆多重加权」的方式，但「反覆多重加权」实际执行时，最大的问题在於其检定方式是透过卡方检定，通常只要其检定P值大於0.5，就认定样本与母群一致，而未考虑一个最佳化的加权值。

Results of the study indicate that the probability-based tagger outperforms the rule-based tagger, and that the probability-based tagger yields an accuracy comparable to that achieved when the tagger is used to tag English native speakers' texts. It is also found that the rule-based tagger does not perform stably, and that its accuracy is often affected by the quality of learner language.
