RESULTS: Virtual anatomical models could concurrently show bony and membranate vertebral canals. These exhibited comprehensive and minute bony anatomic structure of cervical vertebrae and anatomic information regarding dura mater, spinal cord, and nerve sleeve for pre-surgery evaluation and virtual surgery. The imaging virtual anatomic information was in accordance with practical anatomical information in patients.

The theoretical innovation is that endogenous uncertaintytheory is first introduced to explain the abnormal volatility of Chinese stock markethence making the analysis of abnormal volatility more reasonable. The econometricalinnovation is that state space model is introduced to improve the classical test modelmaking the econometric test more practical and more convictive.

在中国股市异常波动性成因的理论分析中，首次将内生不确定性作为其中的一个重要因素，使得对中国股市异常波动成因的分析更为合理；在内生不确性的实证研究中，根据股市的实际情况，引入状态空间模型，对经典的检验模型进行改进，使得实证检验结果更具说服力。

Analysis shows that the proposed modeling method has the following advantages,(1) the aircraft or component geometry is approximated by finite element patches, which may well reflect the reality,(2) the liquid model is considered,(3) critical and noncritical component are modeled separately, so as to reduce the human errors, and (4) it has good interface with the commonly used finite element modeling software, which may reduce the repetitive work.

This study is a kind nonequivalent pretest-posttest designs of quasi-experiment in life education. The experimental group is the six grade class led by the researcher, and the control group is another six grade class of the same school. The researcher executes analysis of covariance of the grade school pupils' life attitude evaluation scale and quality data, in order to explore the meaning, value and feasibility of life education. The researcher wishes to become the reference for someone who wanted to work about the life education by executing the curriculum of life education.

本研究是以实施生命教育课程为主的不等组前后测设计之准实验研究，以研究者实际教学的六年级班级为实验班，另一六年级班级为对照组，进行「国小儿童生命态度量表」前后测的共变数分析，辅以质性资料的分析，来探讨生命教育课程的意义与价值及其可行性，希望能透过研究者对於生命教育课程的实践，成为日后有志从事生命教育工作之参考依据。

A case ofapplication of CAN bus on the distributed automatic system ofsubstation is illustrated.To meet the need ofautomatic controlsystem ofsubstation,a network is necessity because ofthe distributed control units ofthe substation.To shortenthe developed period of the system,an interface bridge between the RS232 and CAN bus is made.The result oftest run shows thatthe requirements ofsystem can be satisfied by the project.

摘 要：对一个把CAN总线应用到分布式变电所自动化系统的例子进行了分析，对于分布式变电所自动化系统来说，通信网络的效率、安全性和实时性具有重要意义，在实际工作中，通过在现行测量、控制和保护单元外增加一个RS232和CAN总线之间的转换器，构成变电所自动化系统的现场总线网络，试运行情况表明：该方案完全能满足系统的要求。

The author has paid attention to the two kinds of lavas which locate the south-east end of the Kalamaili belt. Through the field investigate and the geochemistry experiment the author has contrasted the two kinds of lavas in the ophiolitic melange, made clear the tectonic background and summarized the geochemical characteristic and then discussed the formed environment and tectonic significance.

作者以该蛇绿混杂岩中的两类中基性火山熔岩为研究对象，通过野外实际观察和室内地球化学实验分析，将这两类火山熔岩进行对比研究，弄清其大地构造背景，总结其地球化学特征，并由此探讨该蛇绿混杂岩的形成环境及其构造学意义。
