主要原因

As Congress plumbs the causes of our current mess, the main one is hiding in plain sight: Reckless monetary policy that did so much to create the credit mania and then compounded the felony with a commodity bubble and run on the dollar whose damage is now becoming apparent.

国会正在探究眼下困境的原因，其实主要原因已经一目了然：正是轻率的货币政策催生了信贷膨胀，然后刺激大宗商品价格飙升和美元贬值，最后害人害己。

Compare to other four syndromes,there is significant difference in Hp infection and histopathology.The main reason possible is that Fu Zhou and its peripheral region's specified weather and geographical environment There is a significant difference between light ,medium degree of splenogastric hygropyrexia syndrome and the other four syndromes.it is correlation to the severity degree of sinus ventriculi greater curvature's histopathology.

脾胃湿热证与其他四型相比在Hp感染、胃粘膜组织病理学上均存在显著性差异，分析其原因考虑福州地区特定的气候和地理环境可能是造成这一结果的主要原因；该证的轻、中、重不同程度在Hp感染上存在显著性差异，与胃窦大弯侧粘膜组织病理学的严重程度存在一定的相关性。

Economies such as China or Brazil were walloped late last year not only, or even mainly, because American demand plunged.

类似中国巴西这样的经济体去年年末经济受到重创，美国的需求降低并不是唯一的原因——甚至不是主要原因（中国一半以上的出口面向了其他新兴经济体，而最近中国代替美国成了巴西的最大贸易出口国）。

The acute hemorrhage necrosis pancreatitis is one kind critically ill, the condition is heavy, the prognosis bad pancreatic gland acute inflammation pathological change, as a result of the ductus pancreaticus obstruction, is accompanied by the duodenum either the biliary duct contents regurgitation adds on the pancreatic gland blood circulation insufficiency or the nervous reason, causes the pancreatic juice secretion evacuation barrier, the reversion permeating pancreatic gland essence, causes this sickness primary cause.

急性出血坏死型胰腺炎是一种起病急、病情重、预后差的胰腺急性炎症病变，由于胰管梗阻，伴有十二指肠或胆道内容物反流加上胰腺血运不足或神经性原因，导致胰液分泌排空障碍，逆向渗入胰腺实质，是引起本病的主要原因。

The oxidation-deoxidization between Al and ZrO2 or Y2O3 is one of the mechanisms of high temperature oxidation failure of TBCs. The failure under thermal shock results from the formation of cracks normal to the bond/top coat interface, due to the different coefficients of thermal expansion between bond coat and top coat and the temperature change.

底层与面层之间界面存在的部分Zro，或YZO3被A1还原生成Zr或Y，A1被氧化形成A1203的反应是热障涂层高温氧化失效的原因之一；热震失效的主要原因是由于底层与面层之间热膨胀系数的差异而产生的剪应力与喷涂时产生的内应力之和导致面层产生裂纹。

The main cause of chilling injury in the annual branches was the losing of water at critical period; the reasons of anatomical structure was the thick epidermis, the loose arranging of parenchyma in cortex, and the undeveloped parenchyma in best.

造成1年生枝条冻害的主要原因是生长与休眠临界期枝条的大量失水；其形态解剖学原因是表皮菊，皮层薄壁细胞排列疏松和韧皮薄壁细胞不发达。

The results show that the vibration intensity of the substructure has a connection with the depth of the well, the geological condition and the density of drilling fluid; the horizontal vibration of the substructure is mainly caused by bent kelly; the included angle between the axis of cardan shaft and the derrick floor is also the cause of the vibration in three directions, and the cause of t...

分析结果表明，底座的振动强度与井深、地质条件和钻井液密度有关；弯曲的方钻杆是造成底座水平方向振动的最主要原因；万向轴因与钻台面存在夹角，从而引起底座在三个方向的振动；采用四挡钻进时，万向轴的工频及其倍频接近底座垂直方向的固有频率是引起底座在该方向振动强烈的原因。

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。
