查询词典 anomaly

By using these anomaly evaluation methods, we fail to have a good understanding of the superficial appearance and essence from the development and evolution of the petrogenetic and metallogenic system, and the constraining of anomalies by supergene factors, genetic mechanism of anomalies and geological-geochemical environment produced by anomalies are less studied and only the information of the anomaly itself is extracted and used.

这些异常评价方法缺乏从成岩成矿系统的发展演化上去认识异常的表象与本质，关于表生因素对异常的制约和异常形成机制及异常产生的地质-地球化学环境的研究不够，只是提取和利用异常本身的信息。

The two volcanic materials are similar but are also different ①the partition mode of rare-earth element is similar to that of the basalt.②the increase content of the rare-earth element content in transitional layer shows that it enrichs in this segment due to the volcano events. Moreover, the comparability of the partition mode shows that the volcano-genic materials and the basalt are of the same source.③low Eu anomaly different from the high Eu anomaly of medium-acidic tuff in Meishan section, that show that their formation is different④there are plentiful basalt detritus.⑤there are enrichment of the Ti element.⑥the lower content of siderophile element of Ni and Co, especially in the transitional layer, show that there were not extraterrestrial events and big scale basic or ultrabasic volcano eruption events in this area. These characteristics show that the sedimentary source of Xuanwei Formation and Kayitou Formation is basalt.

1稀土元素配分模式与玄武岩类似；(2)稀土元素含量在异常层的增加反映了火山事件导致了它在该段地层中的富集，而配分模式的相似性反映了火山物质来源与玄武岩具有同源性；(3)低"Eu"异常区别于煤山剖面的中酸性凝灰岩高"Eu"异常模式，说明界线粘土岩成因也不同于煤山剖面的界线粘土；(4)大量的玄武岩岩屑；(5)Ti元素的富集；(6)亲铁元素Ni和Co含量较低，特别是在界线异常层含量降低，表明本区在界线处可能并不存在地外事件和大规模基性、超基性火山喷发事件，这些特征反映本区宣威组和卡以头组物质来源主要为玄武岩。

Unsupervised anomaly detection methods can detect the anomaly records in unlabled dataset. It can overcome the shortcoming of the traditional data mining methods, and automate the labeling and creating process of the intrusion detection model. It has become the useful tool of the intrusion detection.

以聚类为代表的无监督异常检测方法可以在无标记数据集上发现异常数据，克服了传统数据挖掘方法的缺陷，使标记数据集和入侵检测建模过程自动化，成为了入侵检测的有力工具。

Traditional data mining techologies used in data mining need to build intrusion detection model in labled data set. The process to lable data set is all by hands, and if the lables have some errors, the efficiency of the intrusion detection system will be affected. Unsupervised anomaly detection methods can detect the anomaly records in unlabled dataset.

传统的面向入侵检测的数据挖掘技术需要在大量的已标记数据集上建立入侵检测模型，数据集的标记过程需要以手工的方式进行，并且如果标记错误，将导致入侵检测系统检测效率的降低。

Model results show that snow anomaly in spring can cause the thickness anomaly in the troposphere and trigger a wave train of geopotential height anomalies from western Europe extending to East Asia at 500 hPa by changing the distribution of the soil moisture and temperature in succeeding summer.

结果表明，春季积雪异常通过改变其后夏季的土壤湿度和温度分布，造成对流层厚度场的异常，激发一个从欧洲西部到东亚的500 hPa 高度场异常波列。

Several conclusions are drawn from the study. The ore deposit mainly occurs in the lower Cambrian Shuigoukou Formation, which is situated at the limbs of Qingshixia-Yujiatai overturned multiple syncline. The ore-hosted rocks are silicalite and mudstone. The content of SiO2 is high in the rocks of V ore deposit. Silicalites are mainly aphanitic quartz and chalcedony and the barite is sedimentogenic. The correlation between V and Cr, U, Ba is good. The rare earth element distribution patterns show Ce-negative or positive anomaly, obviously Eu positive anomaly and the right dip graphics.

研究结果表明，该区钒矿主要产出于青石峡－余家台倒转复式向斜两翼下寒武统水沟口组下岩段硅质岩夹泥岩的泥岩中，矿体产状与地层产状基本一致；钒矿床中所有岩石都含有较高的SiO2，硅质岩以隐晶质石英和玉髓为主，有沉积成因重晶石；V与Cr、U、Ba相关性好；稀土元素球粒陨石标准化模式具有或正或负的Ce异常和明显的Eu正异常、向右倾的图形。

In the low troposphere G〓 anomaly is compositively caused by both diabatic heating and temperature anomaly.

对流层低层G〓的异常则是温度场和非绝热加热场的异常共同作用影响的结果。

There was consanguineous relationship between summer rainfall anomaly in North China and continual circulation anomaly from spring to summer .

华北夏季降水异常与从春到夏的持续环流异常密切相关。

RESULTS: Two cases which were open fractures were operated at first time. Diplopia and ocular region anomaly were not catch out. All of the 78 cases were treated by conservative treatment first. Conservative treatment was involved high doses of corticosteroid and the use of dehydrating and neurotrophy agents etc. In 41 cases（52%） diplopia completely disappeared and partly disappeared, the enophthalmos was less than 2 mm,and ocular region anomaly reduce.

结果：开放性骨折2例行1期手术，术后无明显复视和眼球凹陷。78例早期均先采用保守治疗，保守治疗包括使用大剂量皮质类固醇激素，高渗脱水剂、神经营养药物等，有41例复视消失或减轻，眼球内陷小于2mm，保守治疗的总有效率为52%。

On the contrary, the anomaly of sensible and latent heat fluxes in winter, spring and autumn over extratropical Pacific are the main factors that lead to the anomaly of SSTA. This implies that atmosphere is active.

在热带海洋及夏季热带外海洋的同期海气热交换中，海洋占主导地位；与此相反，在冬春季和秋季的热带外海洋上，潜热和感热的异常可能是造成热带外海洋海温异常变化的重要因子，也即大气占主导地位。

Objective: To study the effect of polycythemia on blood oxygen saturation.

裴蕾目的：观察RBC剧增而引起的高粘血症对血氧饱和度的影响。
