【摘要】

：

以合欢、刺槐、国槐和皂荚4种豆科树种盆栽实生幼苗为试验材料,研究了NaCl胁迫下4个树种幼苗的生长、耐盐临界浓度和Na+、K+含量的变化,并对其耐盐性进行了比较.结果表明:NaCl胁迫抑制了4个树种幼苗的生长,苗木的干物质积累量减小、根冠比增大,尤其对合欢和皂荚的影响较大;以相对干质量降至对照组50%时的NaCl浓度作为生长临界NaCl浓度(C50)指标,4个树种的耐盐强弱顺序为:刺槐(5.0‰)

Minimum mean square error method for stripe nonuniformity correction

Stripe nonuniformity is very typical in line infrared focal plane (IRFPA) and uncooled starring IRFPA. We develop the minimum mean square error (MMSE) method for stripe nonuniformity correction (NUC).

一种具有新型时钟产生器的无源超高频RFID标签(英文)

给出一种符合ISO/IEC 18000-6B协议的超低功耗的无源超高频RFID标签。为了能够给标签数字基带处理提供准确的时钟,使用了一种超低功耗、自校正的时钟产生器,产生的时钟在-50℃-120℃或者0.7-1.6 V电源电压的范围内,偏差小于4%。此自校正时钟模块的功耗在0.7 V的电源电压下仅为364 nW。一个低压输出参考电压源也集成到了该标签芯片中,该模块产生0.96 V的基准且只消耗10

短期UV-B辐射对青藏高原美丽风毛菊PSⅡ光化学效率的影响

通过短期增补UV-B辐射模拟试验,研究了青藏高原典型天气(晴天、多云、阴天)下高山植物美丽风毛菊叶片的叶绿素荧光参数变化.结果表明:随天气由晴变阴,美丽风毛菊叶片暗适应3min的PSⅡ最大光化学量子效率(Fv/Fm)显著升高,实际PSⅡ光化学效率(ΦPSⅡ)和光化学猝灭系数(qP)也升高,而非光化学猝灭系数(NPQ)则降低,可见光辐射(PAR)是影响PSⅡ光能转化效率的主要因素.增补UV-B辐射后
