Bull; Wine is a living thing,"the more the more Xiang Chen," does not apply to wine: wine bottle stopper with the outside world through the wood and non-stop air exchange of changes in the life cycle of its age is shallow - the development phase - the mature - the peak period - the degradation period - old period.

bull；葡萄酒是有生命的，&愈陈愈香&不适用于葡萄酒：葡萄酒装瓶后透过木瓶塞与外界空气交换而不停变化，它的生命周期是浅龄期－发展期－成熟期－高峰期－退化期－垂老期。

I'm sure that will change at some point.

但我肯定这种情形会有某方面的变化的。

Yet they leave no sort of trace in the archaeological records unless they are captured by a dictaphone or written down by a clerk.

偶说的话，你通过空气振动听见，这当然是人类造成的物质变化，也可能有重大的历史意义，但这些话在考古学中未留下丝毫痕迹，除非有人用录音机录下来或文书把这些话写了下来。

In a database the concept of an example might change along with time which is known as concept drift When the concept drift the classification model built by use of old data is unsuitable for classify new data Therefore concept drift has become a hot issue in data mining in recent years Although many algorithms had been proposed to resolve this problem they can not provide users with the reason of concept drift However a user might be very interested in such rules For example doctors want to find what makes disease change; researchers want to know the reason of the variety of the weather; and decision makers would like to understand why a customer's shopping habit change In this thesis we propose a Concept Drift Rule mining Tree called CDR-Tree to solve this problem CDR-Tree can not only find the rule of concept drift also build the prediction model for both old and new data at the same time

无论在大型资料库或现实生活中，同一资料样本的概念有可能会随著时间的递移而改变，也就是产生所谓的概念漂移。当样本发生概念漂移时，由旧有资料所建构的分类模组将不再适用於预测新获得的资料，因此，近年来概念漂移已成为资料探勘中一项热门的研究议题。虽然已有？多学者提出不同的技术来解决概念漂移的问题，但是这些方法都是利用修正或重建的方式来产生适合新资料的预测模组，并无法提供造成概念漂移的原因。然而对使用者而言，其感兴趣的可能正是这些引起概念漂移的规则，如医生可能想了解引起疾病变化的主因、学者会想要知道气候转变的规则、或是决策者想找出顾客购物习惯改变的因素等。因此，本论文提出概念漂移规则探勘树( Concept Drift Rule mining Tree )，简称CDR-Tree，来解决这个问题。CDR-Tree不但能探测出造成概念漂移的主要原因，亦能同时建立新旧资料的预测模组以供决策者运用使用。

In order to scientifically manage exploration data, three-dimensional database composed of rock mass quality indices is established under the geodetic reference frame. Those indices are obtained from adits, drill holes and outcrops.

大型水电工程往往积累有丰富的勘探资料，如何科学地管理这些资料并将其直观、准确地反映在工程地质图件上，即将岩体结构类型及岩体质量空间变化特征以图形展示，是当前研究的重点和难点之一。
