Then, this system was applied to analyze the influence of interfering factors towards the parameters of LRE for monopropellant (H_2O_2) and bipropellant (N_2O_4/UDMH) system, which include the effect of upstream pressure of the tank and the diameter of the pipelines on the thrust. Thus, the variety of main parameters such as thrust, impulse, and chamber pressure were obtained at rated condition.

本文还以MATLAB软件作为设计平台，使用M文件编写了挤压式液体火箭发动机的静态系统仿真程序，分别针对单组元(H_2O_2)和双组元(N_2O_4／UDMH)推进系统进行了干扰因素对发动机参数的影响分析，包括贮箱上游压力以及管路直径对发动机推力等参数的影响。

Means the parent directory, so this command means to execute "toolchain.sh," which is in the current directory.

代表父目录，所以这个命令就是执行当前目录下的"toolchain.sh"。

Yes,In fact,I'm on our city ream.
