, 2018 本文研究了高温处理对ZnO薄膜及其忆阻效应的影响,发现利用经800℃高温处理后的ZnO薄膜制备的Cu/ZnO/Pt器件依然保持忆阻性能,并观察到无电形成过程的忆阻效应。研究表明,无电形成过程的原因在于高温处理后的ZnO薄膜出现了纳米级通道,使得在沉积顶电极Cu的过程中,形成天然的导电通道 ...

, 2008 采用开顶式生长室(OTC)模拟增温实验,研究了川西北亚高山草甸植物群落碳、氮含量对温度升高的响应。由于OTC的增温作用,在整个生长季内,地温(15cm)、地表温度和气温(30cm)的平均值在OTC内比对照样地分别高0.28、0.46和1.4℃,OTC内土壤相对含水量也明显减少,低于对照样地5.49%。受增温及土壤含水量减少的影响,一年后,植物群落的生物量积累和碳、氮含量发生了明显的改变。除10月份OTC内地上鲜体生物量略高于对照样地外,OTC内地上鲜体生物量和根系生物量与对照样地相比 ...
