针对目前应用人工智能技术进行变压器绝缘故障诊断时所遇到的主要困难，本文进行了深入的研究与分析，进而提出了相应的解决方法，主要的研究工作如下：提出利用可靠性数据分析中累积频率的概念对油中溶解气体分析数据进行归一化处理；并在引入"类属函数"的概念后，结合多元统计分析技术实现了样本的典型性评价与故障特征矢量的选取。

The two selection restrictions are determined by the cognitive function of middle construction. Though middles do not report actual event, they depict the properties of virtual events, therefore, naturally verbs in middles should be event verbs. And middles are cognitively motivated to deemphasize the role of agent in the occurrence of the event and focus the active role a passive participant could play in the occurrence of the event, then a volitional adjective or adverb that is under the control of agent would bring the deemphasized participant back into focus again, which is obviously contradictory to the cognitive motivation of middles.

这两种选择限制是由中动结构的认知功能决定的，中动结构虽然并不报道具体事件，但它描述虚拟事件的特性，因此动词必须是事件动词；同时中动结构之意图是弱化施事的作用而强化被动参与者在事件中的积极作用，因而一个语义上由施事自主控制的形容词或副词必然又会突显施事的作用，这与中动结构的认知动因是相矛盾的。

在弹道仿真计算中，为了既达到要求的仿真精度又能满足实时仿真，分析了仿真步长的选择方法，然后在龙格－库塔转阿当姆斯法中引入变步长积分方法，推导了阿当姆斯变步长积分公式，同时对弹道仿真中的间断非线性系统提出条件函数求零的方法来解算弹道。

By defining a discriminability function and utilizing some images with synthetic defects, a parameter selection method is proposed to adapt to various fabric types when the Gabor filter bank is applied in defect segmentation. It is argued that only the real part of Gabor filter works during segmentation; the radial orientation can be limited to horizontal and vertical direction; the radial frequency and the length of the FIR filter should depend on the basic frequency of the fabric texture.
