准稳态

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.

这对电力系统的建模和仿真提出了更高的要求，传统的机电暂态模型由于建立在&准稳态&假设基础之上，因此不能用来仿真变化迅速的电磁暂态过程；而电磁暂态模型，虽然能准确反映电磁暂态过程，但由于仿真步长很小，仿真速度受到限制，不适合用来仿真大型电力系统。

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.

The production moved off-Broadway to New York City, where she won the Joseph E. Calloway award for her performance, and was profiled in American Theater Magazine as one of ten young theater artists to watch.

生产提出过百老汇的新的纽约市，在那里她赢得了约瑟夫calloway奖，她的表现，并于异型在美国的战区杂志之一， 10战区的青年艺术家观赏。

It's a risk tradeoff, and I believe that adding test support code usually wins.

这是一个风险的权衡，我相信添加测试代码通常会占上风。
