实验结果表明,不同形成电压的样品的起始亮度和工作寿命按高低的排列顺序随工作电压的增加表现出有规律的变化。还发现形成电压不问的DCEL器件在AC条件下的发光特性随工作电压的提高逐渐趋向一致,形成电压的影响逐渐消失。这一现象被解... 实验结果表明,不同形成电压的样品的起始亮度和工作寿命按高低的排列顺序随工作电压的增加表现出有规律的变化。还发现形成电压不问的DCEL器件在AC条件下的发光特性随工作电压的提高逐渐趋向一致,形成电压的影响逐渐消失。这一现象被解释为是由于在AC条件下也存在类似于在直流(DC)条件下的形成过程,即Cu^+迁移过程。老化过程也是形成过程的继续。 展开更多

In order to study NAC transcription factor gene in maize(Zea mays), a completed c NAC encoding the NAC-like gene homologue named as Zm NAC was cloned from the maize inbred line Zheng 58 using a pair of specific primers, which were designed to cover the full coding region according to the reported NAC gene family. The length of the sequences was 953 bp.The deduced amino acid sequences analysis showed that the sequence contained the complete coding region of a typical NAC gene, including a complete open reading frame which was 939 bp. The study analyzed the expression patterns of NAC transcript gene induced in various PEG(polyethylene glycol) simulated drought condition. Real-time PCR indicated that maize NAC gene can be induced in various PEG to abiotic stress responses, it could express constitutively to adopt the drought condition in short time, and the higher drought, the more early expression, which indicated that NAC transcript gene could be involved in the regulation of the defense response. 展开更多
