This paper applied three joint time frequency analysis ( JTFA) methods to a surface discharge signal in oil, i.e., Short time Fourier transformation ( STFT) based spectrogram, Wigner distribution ( DWD) and Gabor spectrogram ( DGS).

The discrete Wigner distribution ( DWD) is a two dimensional representation of a signal in discrete time dimension and discrete frequency dimension.

离散Wigner分布（DWD）是信号在离散时域和离散频域上的二维表示。

The EcmaScript component offers only the core language features& the primitive data types, expression evaluation, flow control, etc.

The arguments array is the ECMAScript standard built-in reference to the arguments passed to this function.

数组arguments是指向传递到这个函数参数的ECMAScript标准内置引用。

The ECMAScript standard is freely available from the ECMA Web site.

In many ways, EcmaScript is a lowest-common-denominator solution to the scripting code compatibility problem among popular Web browsers.

在许多方面，对于流行的Web浏览器中的脚本代码兼容性问题来说，EcmaScript是共同特点最少的解决方案。

Thus far, our discussion has centered around using EcmaScript to simply and easily leverage the APIs of the Java platform.

A third implementation of this new scripting language, called EcmaScript, was meant to standardize the language itself and the DOM.

JavaScript的第三个实现是一种新的脚本语言，称为EcmaScript，其目的是对自己和DOM进行标准化。

Using ECMAScript gives you full programming flexibility, but if all you want is animation, SVG has and related tags ( such as or).

使用ECMAScript可为您提供完美的编程灵活性，但如果您所需要的只是动画，SVG还提供了和相关的标签（如或）。

Most of the control flow statements in EcmaScript should be familiar to Java programmers, as the statements were modeled after the Java programming language.

EcmaScript里大多数控制流的语句对于Java编程人员来说都应该是熟悉的，因为这些语句都是根据Java编程语言的模型设计的。

In particular, you can manipulate SVG within Web browsers ( or other applications) using ECMAScript and the Document Object Model ( DOM).

尤其是，您可以在使用ECMAScript和其他文档对象模型（DOM）的Web浏览器（或其他应用程序）中操纵SVG。

That is, you can code your EcmaScript program to take advantage of the comprehensive APIs of the underlying JDK.

这就是说，您能利用作为基础的JDK的全面API编写EcmaScript程序。

You can enter an EcmaScript program interactively into FESI, or use the File' Open menu to open it in a text file containing an existing EcmaScript program.

您能将一个EcmaScript程序交互式地输入FESI，或使用File Open菜单将它在一个包含着现有EcmaScript程序的文本文件中打开。

The button action event handler, shown next, uses the runFESI method to run the EcmaScript programs.

下面显示的按钮操作事件处理程序使用了runFESI方法来运行EcmaScript程序。

Arrays in EcmaScript are native objects.

EcmaScript中的数组为本地对象。

You will now be able to easily interact with the EcmaScript interpreter and get immediate results.

现在您就能方便地与EcmaScript解释程序进行交互并立刻得到结果。

Then we use the split() method of EcmaScript String to split the content into separate lines.

然后我们使用EcmaScript String的split（）方法将内容拆分为独立的行。

Create Java applications that use a combination of Java and EcmaScript to implement the internal logic.

创建使用Java和EcmaScript的结合来实现内部逻辑的Java应用程序。

Finally, if we want to add some behavior to the object, we first define an EcmaScript function and then assign it as a property of the object.

最后，我们希望在对象中加入一些行为，就先定义一个EcmaScript函数，然后把它指定为对象的一个属性。

This scripting language supports XML data through a group of classes that adhere to the ECMAScript for XML ( E4X) specification.

该脚本语言通过一组遵循ECMAScript for XML（E4X）规范的类支持XML数据。
