The results show that,the kernelized versions of the Xie-Beni index VXB and its emendatory index VK are the most effective and reliable of the indices considered,so can be given the priority as the cluster validity criteria for KFCM algorithm.

将经典的聚类算法推广到核Hilbert空间，是无监督学习领域近年来的研究热点之一[1~6]。然而，和原空间中的聚类算法一样，核化的聚类算法也需要事先给定聚类数目c，这直接影响了这些算法的易用程度和实际性能。众所周知，聚

Methods Twenty-three cases of OSAS patients proved by polysomnography were examined with MRI. The cross-sectional area of retropalatal region, retroglossal region, epiglottal region and the lateral parapharyngeal fat pad of RP region was calculated. The thickness of bilateral and posterior pharyngeal wall and other indices were also measured. 30 nonsnoring age-matched normal subjects were selected as the control group. 15 patients underwent turbo field echo T1-weighted imaging during sleep. The images of RP, RG, and EPG were analyzed. Results In oSAS group, the cross sectional area of RP and RG regions was smaller than that of the control group.

应用MRI对23例经多导睡眠监测（polysomnography， pSG）确诊的OSAS患者及30例无打鼾的健康成人进行上气道检查，于轴面图像测量软腭后区（retropalatal region， RP区）、舌根后区（retroglossal region， RG区）和会厌区（epiglottal region， EPG区）的气道截面积，各区前后、左右径及其比值，各区咽侧壁、咽后壁软组织厚度，RP区咽旁间隙（lateral parapharyngeal fat pad，LPFP）截面积，于正中矢状面图像测量软腭厚度、长度及截面积，对两组各项检查指标进行统计学分析。

This research determined the influence of dietary vitamin E levels on the growth, body composition and various health indices of juvenile Epinephelus malabaricus.

本研究探讨石斑鱼饲料中添加高浓度的维他命E 对鱼体成长、组成与各种健康指标之影响。

The hematic properties and biochemical indices of Epinephelus coioides were studied

Simulation results show that the defined piecewise logistic map is not only ergodic in phase space, and its corresponding chaotic performance evaluation indices are also better.

结果表明，定义的分段logistic映射不仅具有良好的遍历性，而且对应的混沌系统相关评价指标的性能良好。

The finer sizes have lower minimum explosible concentrations and higher explosion intensity. When particle sizes of coal dust are less than 75 μm,minimum explosible concentrations and explosion intensity approach a limiting value. In the concentration range measured ( less than 700 g/m3), maximum explosion pressures, maximum rates of pressure rise and explosion indices increase along with the increase of coal dust concentrations. Explosion intensity rapidly enhances along with ignition energy augmenting. Explosion reaction is weak while ignition energy is less than 1 kJ.

煤粉越细，其爆炸下限越低，爆炸烈度越大，但煤粉细到75 μm以下后，这种变化趋势趋缓；在所测浓度范围内(小于700 g/m3)，最大爆压、最大压力上升速率和爆炸指数均随煤粉浓度增大而增大；爆炸烈度随点火能增大而迅速增强，点火能小于1 kJ时各煤样在不同浓度的爆炸都很微弱。

IOS is capable of presenting the distinctive indices for the study of respiration impedance on patients with extratracheal tumour.

IOS能为气道外肿物的呼吸阻抗研究提供较特征性的功能指标。

With the increase in dietary fat, the fish had high hepatopancreas somatic indices and muscular exudative losses.

肌肉渗出性损失和肝体比随饲料脂肪水平的增加而逐渐升高。

Objective To assess the liver function and liver fibrotic indices in the patients with Nonalcoholic Fatty Liver Diseases.

目的探讨非酒精性脂肪肝病人血清肝功能指标和肝纤维化指标的变化。
