In this paper, the evolution of the patte transition induced by the vortical electric field (VEF) is investigated. Firstly, a scheme is suggested to generate the VEF by changing the spatial magnetic field. Secondly, the VEF is imposed on the whole medium, and the evolutions of the spiral wave and the spatiotemporal chaos are investigated by using the numerical simulation. The result confirms that the drift and the breakup of the spiral wave and the new net-like patte are observed when different polarized fields are imposed on the whole medium respectively. Finally, the patte transition induced by the polarized field is discussed theoretically.

随着“温室效应”的不断加剧,短期异常高温发生越发频繁,高温已经成为制约农业生产的重要非生物胁迫之一。开展花期高温胁迫对不同基因型玉米产量、品质及光合特性影响的研究很有必要。本研究以耐热玉米基因型浚单20和热敏感基因型驻玉309为材料,分别于花前(吐丝前0~8d)和花后(吐丝后0~8d)高温处理,研究高温胁迫对其产量品质的影响及其生理机制。主要结果如下:1、花期前后高温对玉米产量品质形成的影响及其生
水稻作为我国重要的粮食作物之一,其产量的稳定与增长对我国的粮食安全具有极其重要的意义。但是,目前我国水稻的产量一直徘徊不前,遗传资源的狭窄是造成这一现状的主要原因之一。为了进一步拓宽和丰富水稻的遗传资源,把水稻远缘种中的优异基因导入到栽培稻中是行之有效的方法。野生稻具有一些天然的优良性状,比如对盐碱、干旱及病虫害的抗性等。如果能将这些优良的基因引入到栽培稻中,将使栽培稻的综合品质得到很大的提高。但
