鉴别分析

To make the identifications, you need to add a second step, called mass spectrometry.

对化合物的鉴别需要进一步使用质谱分析技术。

Objective To study the multi-slice CT features and pathological basis of diffuse consolidation bronchioloalveolar carcinoma in order to differentiate it from lobar pneumonia, cheesy pneumonia.

目的：分析弥漫实变型肺泡癌的多层螺旋CT影像表现及其病理基础，探讨与大叶性肺炎、干酪性肺炎的鉴别诊断。

An automatic algorithm was used in the analysis to identify clusters of groupings of patients. We used the classical unsupervised clustering method called the Iterative Self-organizing analysis technique of DATA analysis originally introduced by Ball and Hall.25 The technique allows the splitting and merging of clusters while trying to find the "best" configuration. It therefore, requires very little a priori knowledge about the data and predefining the possible number of clusters or groups is not required. The range of possible minimum and maximum number of clusters within which the algorithm can search for an optimal configuration was determined by a procedure called the chainmap which reorders the multidimensional data in the form of a 2D distance map.26 A patient vector is randomly selected and its nearest neighbor is identified as that with the shortest distance between the 2 patients' vectors.

使用自动算法来分析鉴别患者组的聚类，我们使用经典的最初由Ball和Hall提出的的非监控聚类方法，该技术允许在寻找&最佳&形态使对聚类进行拆分和组合，他不需要对数据专门的知识和对聚类或群的可能数量进行预设，在聚类可能的最大和最小范围内，算法可以通过一个叫Chainmap的程序寻找最理想的形态，该程序记录了来自2D距离图的多维数据。

The South Tyrol Archaeological Museum in Italy's northern Alto Adige region, where the remains are housed, announced the findings of Rollo's research Friday. Rollo's findings also appear in the February issue of the American Journal of Physical Anthropology, the statement said.

据美联社2月4日报道，声明说，此项研究的负责人、意大利卡美日诺大学的人类学家同时也是DNA分析专家的佛朗哥·罗洛确定，尽管该男子的特殊DNA属于一个首次被鉴别出来的亚组，但他的基因结构属于欧洲8种基础基因构成中的一种。

Objective To analyze the histogenesis, classification, incidence, clinical feature, the key point of differential diagnosis and histopathologic characteristics of ciliary body neoplasms to provide the basis for clinical diagnosis and treatment.

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
