做记录

In the aspect of the study of the application of HHT method, This dissertation has done three part of jobs: first, the Elcentro strong ground motion which is in common use in earhtquake engineering is analyzed by HHT method, getting its amplitude-frequency-time distribution and the comparison between the HHT marginal spectrum and Fourier spectrum is also made; second, the typical nonlinear system defined by the Duffing equation is analyzed by HHT method, getting its numerical value's amplitude-frequency-time distribution and the comparison between the HHT marginal spectrum and Fourier spectrum is also made; third, define the stationary degree of non-stationary signals making use of 3-D time-frequency spectrum and marginal spectrum, the stationary degree curve of Elcentro seismic recording is protracted according to its defining formula, the stationary degree curve of Elcentro seismic recording which change with time is protracted according to similiar definition.

在HHT方法的应用研究方面，本文做了三部分的工作：首先，利用HHT方法分析了地震工程中常用的Elcentro非平稳强震记录，得到了该记录的振幅－频率－时间分布特性，并将得到的边际谱与傅立叶谱做了比较；其次，应用HHT方法分析了典型的非线性系统－Duffing方程，得到了该方程数值解的振幅－频率－时间分布特性，并将得到的边际谱与傅立叶谱做了比较；最后，利用三维时频谱与边际谱定义了非平稳信号的平稳度，并依照其定义式绘制了Elcentro地震波记录的平稳度曲线，依照类似与依赖与频率变化的平稳度定义，初步尝试编程绘制了Elcentro地震波随时间变化的平稳度曲线。

Experiments on the effects of flood for agricultural crops were done in Zhumadian. corn was selected as the experimental material, and choosing 3 days, 5 days and 7 days submerged days and the jointing stage, tasselling stage for artificial irrigation respectively. The field was given conventional management. After harvest, we recorded various characters and production data, and then compared them with the controlled areas. Then analysis and assessment of the impact of main flood factors on the crops were built.

2在驻马店市驿城区申庄村进行农作物洪水影响田间试验，用玉米作为试验材料，选取3 d、5d、7d三个淹没天数和拔节期、抽雄期两个淹没阶段分别对其进行人工灌水，田间采取常规管理，在作物收获后对玉米的各个性状及产量数据做记录并和对照区进行对比，进而分析和评估洪水灾害发生时对农作物的影响情况。
