The resolution and classical noise in ghost imaging with a classical thermal light are investigated theoretically. For ghost imaging with a Gaussian Schell mode
水稻是世界上最重要的粮食作物之一,全球一半以上的人口以稻米为主食。随着社会的不断发展,人们对于水稻的产量和稻米的品质提出了越来越多的要求,提高水稻的单产并改善稻米的品质成为水稻育种家最为主要的育种目标。非洲栽培稻种质资源中广泛存在着各类抗病虫、耐盐碱、抗旱、耐高温等相关性状的优良基因,而且亚洲栽培稻与非洲栽培稻之间具有强大的种间杂种优势,若能将非洲栽培稻中的优良基因引入到亚洲栽培稻中,并很好的利用
回首德豪润达股权分置改革的历程,在成功的喜悦当中,也有很多令人回味和难以忘怀的记忆和感喟……一、大股东因势利导,全力支持股权分置改革受到国内外经营环境变化的影响,公
An analytic configuration interaction method based on variationally optimized inteally orthogonalized modified Laguerre orbitals is presented. We have developed
We have established a caesium double magneto-optical trap (MOT) system for cavity-QED experiment, and demonstrated the continuous transfer of cold caesium atoms
This paper has studied the barium spectra in exteal magnetic and electric fields on the recently-built system based on a super-conducting solenoid with high sta
教书之余,尚有一丝闲暇,无意间摊开一家省报的历年合订本浏览,发现有两条新闻的标题几乎相同,内容大体一样。但是,时间间隔长达7年又8个月,油然使人感到莫名其妙。这两条新
In this paper the conservation theorems of the constrained Birkhoffian systems are studied by using the method of integrating factors. The differential equation
甘蔗为重要的糖料作物和经济作物,通过培育新品种,结合栽培技术来提高甘蔗糖分、产量、抗逆性,是甘蔗糖业的主要发展方向。乙烯在植物生长发育过程中具有重要调节作用,对乙烯信号转导途径及其相关基因已有不少研究,获得了多个受体基因,但对受体基因调控机理尚未清楚。乙烯利能够显著提高甘蔗的产量、蔗糖分、抗逆性,但其作用分子机理也未明确。因此,本实验以新台糖22号为材料,进行了甘蔗乙烯受体基因SoERS1表达、遗
We propose a nearly perfect optical scheme for the quantum teleportation of entangled coherent states using optical devices such as nonlinear Kerr media, beam s
