Due to its good effect in the reservation of information of signal abrupt change, mathematical morphology is often applied in the detection and location of short-term power quality disturbance, however, there is still a defect of invalid detection existing in partial detection methods based on mathematical morphology while some zero-crossing disturbances are detected. In this paper three mathematical morphology based disturbance detection and location methods, i.e., the method based on first-order derivation and morphological gradient, the method based on morphological gradient and soft threshold processing and the method based on dq decomposition and top-hat transform, are analyzed, that is, by means of simulation the adaptability of these methods in the analysis on the signals of voltage sag, voltage swell and electromagnetic transient oscillation is compared.

数学形态学因其在保留信号突变点信息方面有很好的效果，因此常用于短时电能质量扰动的检测和定位，但基于数学形态学的部分方法仍存在对某些过零点扰动检测失效的缺点，文章分析了3种基于数学形态学的扰动检测和定位方法，即基于1阶求导和形态梯度的方法、基于形态梯度和软阈值处理的方法、基于dq分解和高帽变换的方法，通过仿真比较了3种方法在分析电压暂降、电压暂升、电磁暂态振荡等信号方面的适应性，结果发现基于dq分解和高帽变换的方法在检测过零点扰动时具有很好的效果，因此选取这种方法对实测扰动数据进行了检测和定位分析。

This conclusion supported the theory that green light emission mechanism of ZnO thin films attributed to electron transition from conduction band to oxygen vacancy defect level.

阐述了绿光发射机理，建立了绿光发射的理论模型。

The analytical results of Positron annihilation technology demonstrate that electronegative defect centers exist in the phosphor.

首次利用正电子湮灭分析手段，证实了SrAl〓O〓：Eu，Dy磷光体中存在带负电的缺陷中心。

Modified Ruffa Model not only considered the effect of electrovalence, coordinates, bond length, ion radii, structure, but also the effect of ionicity and thermal defect of minerals on their thermal expansion.

由此，我们提出"利用理论模型作为基础，针对不同种类的矿物采用晶体化学方法作修正，将经验晶体化学方法和理论计算方法结合在一起"的矿物热膨胀系数定量计算思路。

Various [BO6] units exhibit remarkable differece in stability, ion size and ion electrovalence. Therefore, the growth interfaces with electric charges would make a choice among those [BO6]growth units, resulting in the short range of fluctuation in composition and structure at the stage of crystal growth and preparing for the aubsequent formation of ordered domains and other chemical defect clusters.

在基元组装过程中，各种[BO6]八面体基元在稳定性、尺寸大小与电价上的分异致使生长界面对基元有一定的选择性，从而造成了晶体生长时成分与结构的短程起伏，并为有序畴及其它化学缺陷团簇的形成提供了条件。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
