本研究针对数字驱动型硅基OLED(Organic Light-emitting Diode,OLED)微显示器在显示动态图像时引发的视觉感知问题,尤其是动态假轮廓和闪烁现象,提出了一种新的扫描策略——集中式融合扫描。集中式融合扫描策略采用灰度权值重分配和融合子场概念,通过对整数子场数目和权值的重新分配,以及将融合子场固定于调制周期中间位置,改善显示器图像质量。实验结果表明,集中式融合扫描在峰值信噪比方面较传统扫描方法平均提高约13%,均方误差降低了约10%,并且结构相似度评分接近1,显著高于现有扫描方法。集中式融合扫描在JEITA闪烁评估中的表现优于19子场扫描法,闪烁量化值降低了约22%。集中式融合扫描策略在改善数字驱动型硅基OLED微显示器的图像显示质量方面提供了一种有效解决方案,为未来显示技术的研究和创新提供了新的方向。

主季减氮增密对再生稻产量形成特性的影响

华北农学报 2024年第4期39卷 170-178页

作者：郑德超田琴琴王罕陈秋红黄新杰易镇邪湖南农业大学农学院湖南长沙410128 衡南县农业农村局湖南衡阳421100 湖南生物机电职业技术学院湖南长沙410127

为探明减氮增密对再生稻产量形成特性的影响,以杂交稻品种创两优669为材料,在3个施氮水平(N1:180 kg/hm^(2);N2:153 kg/hm^(2);N3:126 kg/hm^(2))与2个株行距(M1:20.0 cm×16.7 cm;M2:16.7 cm×16.7 cm)条件下开展了2 a大田试验。结果表明,减氮降低再生稻叶面积指数(LAI),但合理减氮范围内增密可提高主季和再生季的LAI,互作处理N1M2与N2M2的LAI较高;减氮和增密均降低再生稻叶片SPAD值,但密度影响不显著;减氮导致干物质质量下降,而增密可显著提高干物质质量,互作处理N1M2与N2M2干物质质量较高。减氮降低再生稻产量,但在合理减氮范围内增密可提高产量,互作处理N1M2与N2M2产量较高。减氮显著降低主季有效穗数、穗粒数和再生季再生率、有效穗数,但增密对穗数有弥补作用,合理减氮增密(N2M2)能够协调产量构成因素的关系,从而获得较高产量。相关分析表明,合理减氮增密主要通过提高主季和再生季的LAI和干物质质量,提高主季的有效穗数和穗粒数以及再生季的有效穗数,进而提高再生稻产量。综合来看,减氮增密处理N2M2(施N 153 kg/hm^(2)、株行距16.7 cm×16.7 cm)可以节氮15%,并可获得较高产量。

为探究减氮增密对杂交稻产量与镉积累转运的影响,以创两优669为材料,设置3个氮肥水平(N1180 kg/hm^(2)、N2153 kg/hm^(2)、N3126 kg/hm^(2))与2个密度(M120.0 cm×16.7 cm、M216.7 cm×16.7 cm)处理,在湖南郴州镉污染稻田开展大田试验。结果表明:减氮使水稻干物质重、有效穗数、每穗总粒数和产量降低,但增密可提高有效穗数和产量,本试验条件下以N1M2处理的产量最高,N2M2处理次之;密度对水稻镉吸收转运的影响在年度和器官之间存在差异,减氮可降低土壤有效镉含量和根—叶镉转运系数,从而降低部分器官的镉含量;N1处理的糙米镉含量高于国家标准(0.20 mg/kg),而N2、N3处理的糙米镉含量低于国家标准,且显著低于N1处理。综上,减氮增密主要是通过减氮实现水稻降镉,减氮15%~30%可使糙米镉含量降到国家安全标准以下。综合产量与糙米镉含量,N2M2(减氮15%、增密)为最佳减氮增密处理,可在显著降低糙米镉含量的同时获得较高产量。

搭建了一个基于多丝正比室读出的屏栅电离室探测器,使其保留屏栅电离室屏蔽特性的同时具备雪崩放大功能,通过在探测器内部对原初电离信号进行预放大,以提高信噪比,改善探测器的能量分辨率。利用241Am源详细测试了探测器在不同气压、沉积能量、阳极丝径时能量分辨率及增益随阳极电压的变化关系。探测器最佳能量分辨对应的工作电压与入射粒子在漂移区中沉积的能量有关,能量沉积越小,对应的最佳工作电压越高,探测器的增益越大。对于5.486 MeV的241Am α粒子源的能量分辨率可达1.45%。
