| 5. | It is the question that i think in the thesis . according to the observation of seismic - electrical abnormal signals in the past more than ten years , i determine the object of this thesis is the study on the correlativity between seismic - electrical abnormal signals and volcanic eruptions
本文正是从这个大的思维视角出发，以北京工业大学地震预报研究室多年的地电资料为依据，确定本次论文的主要研究内容为地电异常信号与火山喷发相关性的研究。 |
| 6. | An anomalies in the dielectric constants and loss tangent have been observed experimentally in the ferroelectromagnet near the antiferromagnetic transition temperature , indicative of a coupling between the ferroelectric and magnetic ordering , but the nature of the mechanism of magnetoelectric coupling and the form of interaction is still an important and debated issue
而另一类是铁电磁体，它除了具有一般磁电体的性质外，还由于固有的本征磁有序和铁电有序的耦合使之存在自发的磁电效应。实验上已经发现了由于自发的磁电耦合导致的介电异常和损失正切。 |
| 7. | By magnetoelectric coupling , the application of an electric field or ferroelectric polarization can change one or more of the parameters governing the ma gnetic behavior of the system . correspondingly , being possible magnetostrictive effect or electron - phonon interaction , the fluctuation of spin ordering may lead to a dielectric anomaly and ferroelectric relaxation
通过磁电耦合，铁电有序或外电场可导致自旋的再分布而改变系统的磁性性质，同样由于自旋有序的涨落通过磁致伸缩或可能的电-声子作用可导致铁电弛豫或介电异常。 |
| 8. | Second , i transform seismic - electrical data and volcano data worldwide from 1991 to 1999 to appropriate statistic models and analyze them by using the theories of random process and correlation . the results of the study testify that it is correlative between the seismic - electrical abnormal rectangle pulsation signals and volcano eruptions . so the study is a useful exploration for which whether we can monitor and observe worldwide volcanic activity in the whole
接下来应用随机过程与相关理论的知识，以1991年1月1日至1999年12月31日为统计时间段，以北京工业大学地震研究所南北方向地电脉冲仪所记录到的地电异常矩形脉冲信号和全球范围内的火山喷发事件为研究对象；抽取适合分析、又具物理意义的多个统计模型；并对信号模型与喷发模型间进行了详尽的相关性分析。 |
| 9. | In the first part of our research , we analyzed the causality hiding in substation abnormal condition processing , constructed one tree - like knowledge model ; based on this model , inference engine and database was designed ; finally , the first es was realized in visual c + + developing environment . in addition , for the sake of customer ' s maintaining this system , one customer - oriented knowledge editor was developed
在变电异常检查处理专家系统的研究中，我们分析了变电异常检查处理中蕴涵的因果关系，创建了一种树状知识模型；根据这个知识模型，进行了推理机和数据库的设计；最后，在visualc + +开发平台上对这个系统进行了编程实现。 |
