求翻译：。设计实验方案，包括实验装置，实验地形和实验具体实施步骤的确定。通过对时域数据和经功率谱密度转化的频域数据进行分析，得出结论。是什么意思？

. Experimental design, including experimental setup, experimental terrain and experimental determination of the specific implementation steps. Concluded by the time-domain data and by the power spectral density into the frequency domain data analysis.

. Design experimental program, including lab equipment, lab experiments terrain and concrete steps toward implementation. By the time-domain data and the power spectral density into the frequency domain analysis of data, and draw conclusions.

.Design testing plan, including test installation, experimental terrain and experimental concrete implementation step determination.Through which transforms after the power spectral density carries on the analysis to the time domain data and the frequency range data, draws the conclusion.

。 Experimental programme design, including experimental, experimental terrain and determination of the concrete implementation steps. By time-domain data and the transformation of power spectral density analysis in frequency domain data, draw conclusions.
