In this paper, we report a pulsed digital micro-holography system for recording ultra-fast process of the order of femto-second.

采用脉冲数字全息技术实现对飞秒级超快动态过程的数字显微全息记录。

Based on the second-order coherence function theory, authors have studied nonlinear effects of third-and fifth-order on polarization beats in a cascade three-level system (TPBCTS and FPBCTS).

本文采用二阶相干函数理论研究了级联三能级系统中三阶及五阶极化拍频(TPBCTS及FPBCTS)的非线性效应。

The vehicle steering system is a slowly varying non-linear system, in a short time interval, its dynamic characteristics can be described by a parameter-varying second-order linear system.

汽车转向系统是一个缓慢变化的非线性系统，在一个较短的时间间隔内，可以用一个参数时变的二阶线性系统对其动力学特性进行描述。

In this paper, the numerical results of burning gas flow in the vertical launch system of a rocket are reported. A second-order accurate MUSCL scheme is employed.

本文报导了火箭垂直发射系统燃气流场的数值计算结果，在计算中采用二阶精度的MUSCL格式。

Because the signal processed by fuzzy controller is based on system behavior rather than its analytical model, open loop responses of a robot are described by a set of second order systems.

因为模糊逻辑控制器的控制信号是由系统的响应行为而不是由其分析模型决定的，所以机器人的开环响应可以用一系列二阶系统来描述。
