基于欧拉梁的假设,将双晶片简化为3层压电层合梁,由Hamilton原理建立系统的动力学模型,得到描述轴向预压缩压电双晶片的偏微分方程及特定边界条件,通过求解上述微分方程的边值问题得到双晶片在不同轴向力下的输出特性的解析表达式。利用有限元软件对双晶片进行仿真,验证了理论分析的正确性,增加理论分析结果的可信度。最后通过实验的方法研究双晶片的静、动力学特性,证明了施加轴向力可以降低双晶片的弯曲刚度和固有频率,显著增加其机电耦合效率,提高力和位移输出能力。轴向力虽然会影响双晶片启动时的位移峰值,但是对响应时间和带宽影响较小,大轴向力下双晶片仍具有带宽高与响应快的优势。

[目的]探究中国农业用水绿色效率的时空分异及演变特征,分析中国农业发展现状,为进一步推进农业高质量发展提供科学参考。[方法]利用超效率(evidence-based model,EBM)模型测算2001—2020年中国内地31个省区(不含港澳台地区)的农业用水绿色效率。在此基础上运用核密度(kernel density estimation,KDE)估计法进行非参数检验,并通过ArcGIS图示法探究全国不同地区农业用水绿色效率的时空分异及演进特征,最后利用地理探测器考察不同驱动因素对农业用水绿色效率的综合影响。[结果](1)2001—2020年全国农业用水绿色效率(各省年平均)经历了先上升后下降的变化。(2)全国的农业用水绿色效率在空间上呈现出“北低南高”“西低东高”的现象。(3)全国农业用水绿色效率地区差距呈缩小态势,存在动态收敛性特征,各个省份内部的农业用水绿色效率均存在不同程度的两极分化现象,其中西北地区的核密度曲线最为平缓,两极分化现象最为严重。(4)技术水平、资源禀赋、生态环境对中国农业用水绿色效率的影响程度整体高于经济发展水平。[结论]各省区应结合自身优势,从农业技术水平、农村社会福利等方面出发,推动提升农业用水绿色效率。
