Results The Kappa coefficients of 'liver parenchyma≥gradeⅡ' with 'right midclavicular subcostal' and with 'portal vein diameter' were 0.4131 and 0.4655 respectively, higher than normal level. The degree of their consistency was fair, and others showed poor or almost no consistency.

结果以"肝实质Ⅱ级以上"与"肝锁骨中线肋下"和"肝门脉内径"的一致性系数Kappa值较高，分别为0.4131和0.4655，仅为中等程度的一致性，其余为弱一致性或无明显一致性。

Those four classification models work well in first class of Chinese Vegetaion Division. The KAPPA value of Holdridge Life Zone System,at high value of 0.57,would probably more effective than the others. But in specific area,like tibetan plateau,all of those models need to be refined or consider more elements and factors. This research also points out that the concept and technology of Digitall Earth would promote and push forward the climate-vegetation relationship research,especially in climate-vegetation factors,climatically parameters and modeling parameters,real time dynamic monitoring,effectively managing the magnitude data of climate-vegetation relationship information and supporting the mainframe of Functional Types Modeling Library.

这四个传统的分类方法在中国植被区划一级分类上是适用的，Holdridge生命地带系统KAPPA一致性指数达到0.57模拟效果优于其它三者，但在特定地区，如青藏高原，所有模型均需改进优化或启用新的模型因子才能很好地区分植被亚地带，本研究还指出，数字地球技术的应用有助于推动气候—植被关系的研究，尤其在气候—植被指标的大范围实的动态监测、气候—植被关系数据的海量信息高效、有序基础管理和功能模型库支撑框架体系方面。

Methods DSA was performed in 56 patients with intercranial artery TIA and the clinical and distribution of carotid artery stenosis were analyzed, while TCD was performed in 46 patients and CTA was performed in 54 patients with TIA, then sensitivity, specifity and total consistent rate of TCD and CTA were calculated with Kappa test.

选取56例颈内动脉TIA患者行全脑血管造影检查，结合DSA检查结果分析其临床及颈动脉狭窄特点；同时对46例患者进行了TCD检查，54例患者进行了CTA检查，应用Kappa检验分析TCD和CTA检查的敏感性、特异性和符合率。

Occurrence records from 1864 locations and 34 environmental variables from Daymet datasets were gathered, four modeling methods including Logistic Regression, Classification and Regression Trees, Genetic Algorithm for Rule-Set Prediction and maximum entropy method were used to generate potential geographic distributions for Dreissena polymorpha in the continental USA. Then three statistical criteria including area under the Receiver Operating Characteristic curve, correlation and Kappa were calculated to evaluate the performance of the models, followed by analyses of major variable contributions.

论文以1864个美国外来入侵物种斑马纹贻贝定点发生数据和开放式基础地理信息数据库Daymet的34个环境变量为主要信息源，采用逻辑斯蒂回归、分类与回归树模型、基于规则的遗传算法、最大熵法4种途径，建立美国大陆部分潜在生境预测模型，从接受者运行特征曲线下面积、Pearson相关系数、Kappa值3个方面来检验模型预测精度，在此基础上分析斑马纹贻贝的空间分布规律及其环境影响因素。
