two-impulse trajectory

In this paper, MATLAB software is used to work out the computer program for solving the two-rank differential equations which describe the nonlinear capture of the two-rank PLL. The computer then draws automatically the phase trajectory and time response diagram.

采用MATLAB软件，编制了求解描述二阶PLL非线性捕获的二阶非线性微分方程的程序，计算机自动绘制了相轨迹和时间响应图；

Design and Analyze Optimum Two-Impulse Transfer Trajectory for Exploring Asteroids

小行星探测最优两脉冲交会轨道设计与分析

Within two hours, the Minor Planet Center used sightings by others to chart its trajectory.

在两个小时内, 国际小行星中心就利用他人的观测信息跟踪到了它的轨迹.

In order to solve the problems caused by coupling of multiple segment trajectories, the all-up trajectory optimization design problem is divided into two segment trajectory optimization design problems based on the decomposition optimization approach.

针对多个轨道段相互耦合问题，基于分解优化策略，将整个发射轨道设计问题分解为两个轨道段设计问题。

In this paper, a two fluid trajectory ( continuum trajectory, CT) model ( Eulerian Eulerian Lagrangian) is used for simulating turbulent reacting gas particle flows and coal combustion in a tangentially fired furnace.

本文采用双流体轨道模型（颗粒相连续介质轨道模型）对一个四角喷燃模型炉内三维湍流两相流动及煤粉燃烧进行了模拟。

Then, use two methods to make the simulation. The result shows that the trajectory prediction method based on parameter identification with high generality, rapidity and accuracy can provide a basis for ballistic deflection correction and trajectory control.

结果表明，基于参数辨识的弹道预报具有通用性、快速性和准确性，可以为弹道修正及弹道控制提供基础。
