Acoustic Emission is a class of universal phenomena whereby transient elastic wave are generated by the rapid release of energy from localized sources within a material. In various field, people begin to use this phenomena to test these structures damage and evaluate their security.

聲發(fā)射是材料中局部源快速釋放能量而產(chǎn)生瞬態(tài)彈性波的一種普遍物理現(xiàn)象，人們已經(jīng)開始在各個領(lǐng)域中利用這種現(xiàn)象進行研究對象的缺陷檢測和安全性評價。

It also becomes more difficult to model and simulate power grid. Traditional"Quasi-stationary"phase models can't be used for studying electromagnetic transient phenomena; on the other hand, the EMTP models can be used to analyze the electromagnetic transient accurately, but for the limitation of the step size, it can't be used to simulate the large network with a high speed.

這對電力系統(tǒng)的建模和仿真提出了更高的要求亚洲黄色免费观看，傳統(tǒng)的機電暫態(tài)模型由于建立在&準穩(wěn)態(tài)&假設(shè)基礎(chǔ)之上，因此不能用來仿真變化迅速的電磁暫態(tài)過程亚洲综合色图网站；而電磁暫態(tài)模型思思伊人久久大香线蕉av，雖然能準確反映電磁暫態(tài)過程，但由于仿真步長很小91大神福利导航，仿真速度受到限制国产欧美二区第一页，不適合用來仿真大型電力系統(tǒng)。

The dynamic phasor model is based on the time-varying phasor, which not only breaks the quasi-stationary assumption, but also overcomes the maximum step size constraint of regular transmission line, so it can be used to analyze the fast electromagnetic transient phenomena at a higher speed.
