华中理工大学学报 1994年第3期22卷 47-51页

作者：陈鸿孙学信曾羽健韩才元华中理工大学煤燃烧国家重点实验室

研究了合山煤燃烧过程中挥发分的析出机理，并与惰性气氛中煤的热解机理进行了比较，发现两者是有所不同的。计算了残焦的反应性，结果表明残焦反应性与成焦条件有关，并且在煤焦的整个燃尽过程中是变化的，这种变化与焦中残存的挥发分... 详细信息

研究了合山煤燃烧过程中挥发分的析出机理，并与惰性气氛中煤的热解机理进行了比较，发现两者是有所不同的。计算了残焦的反应性，结果表明残焦反应性与成焦条件有关，并且在煤焦的整个燃尽过程中是变化的，这种变化与焦中残存的挥发分、活性基等密切相关。

Background: Frontotemporal dementia (FTD) and Alzhei- mer’ s disease are clinically distinct disorders, yet neuropsychological stu dies have had variable success in distinguishing them. A possible reason is that studies typically rely on overall accuracy scores, which may obscure difference s in reasons for failure. Objectives: To explore the hypothesis that analysis of qualitative performance characteristics and error types, in addition to overall numerical scores, would enhance the neuropsychological distinction between FTD and Alzheimer’ s disease. Methods: 38 patients with FTD and 73 with Alzheimer’ s disease underwent assessment of language, visuospatial abilities, memory, and executive function, using a neuropsychological screening instrument and standar d neuropsychological tests. In each of these cognitive domains, performance char acteristics and error types were documented, in addition to numerical scores on tests. results: Whereas comparison of neuropsychological test scores revealed so me group differences, these did not occur consistently across tests within cogni tive domains. However, analysis of performance characteristics and error types r evealed qualitative differences between the two groups. In particular, FTD patie nts displayed features associated with frontal lobe dysfunction, such as concret e thought, perseveration, confabulation, and poor organisation, which disrupted performance across the range of neuropsychological tests. Conclusions: Numerical scores on neuropsychological tests alone are of limited value in differentiatin g FTD and Alzheimer’ s disease, but performance characteristics and error types enhance the distinction between the two disorders. FTD is associated with a pro found behavioural syndrome that affects performance on cognitive assessment, obs curing group differences. Qualitative information should be included in neuropsy chological research and clinical assessments.
