| 9. | We examin e the generation of bell state in bose - einstein condensates of two interacting species trapped in a double - well configuration analytically and the density of probability for finding the entangled bell state is given . we find that the oscillation amplitude of the probability of density for finding the entangled bell state becomes greater as the ratio of the interspecies interaction strength and the tunneling rate increases , moreover the self - interaction strength of the component a ( b ) has no effect on it . also we use the time - dependent su ( 2 ) gauge transformation to diagonalize the hamilton operator , obtain the berry phase and analytically the time - evolution operator 此外我们还研究了在双阱玻色-爱因斯坦凝聚中纠缠态的演化,研究发现随着组分间相互作用和随穿率的比值的增加系统演化到bell态的概率变大,而且组分自身内在的相互作用对形成bell态的几率没有影响;并且用含时su ( 2 )规范变换对角化哈密顿量得到了系统的berry位相和时间演化算符,并研究了量子随穿过程。 |
| 10. | Both oxyopes sertatus and harpactor fuscipes are important predators of common cutworm ( spodoptera litura ) on tobacco . the effect of several interference factors on the predations of o . sertatus and h . fuscipes on the larvae of s . litura were examined in laboratory . the results indicated that there were significant mutual interferences on their predations with the existence of other individual in the same / different species . as the number of the predator increased , the predation rates decreased significantly . the interference coefficients ( m ) within h . fuscipes and within o . sertatus were 0 . 7278 and 0 . 6911 , respectively , while the interference coefficient ( m ) between o . sertatus and h . fuscipes was 0 . 9464 . these results showed that the effect of mutual interference on predation in interspecies was more obvious than that in intraspecies . the number of prey captured and the predation rate of predator dropped with increasing the number of tobacco stalks . this result suggested that spatial heterogeneity was also an important factor affecting the predation of predator on prey 斜纹猫蛛和红彩真猎蝽均是烟草上斜纹夜蛾的重要捕食性天敌.室内测定几种干扰因素对斜纹猫蛛和红彩真猎蝽捕食作用的影响,结果表明这些干扰因素对斜纹猫蛛种内、红彩真猎蝽种内和两种捕食者种间的捕食作用均有明显的干扰作用,随捕食者数量的增加,其对斜纹夜蛾捕食作用率显著降低.斜纹猫蛛种内的干扰系数和红彩真猎蝽种内的干扰系数分别为0 . 7278和0 . 6911 ,而两者种间的干扰系数为0 . 9464 ,说明两者种间的干扰作用要明显高于同一种捕食者种内的干扰作用.两种捕食性天敌对斜纹夜蛾的捕食量和捕食作用率随烟草茎杆数的增加而降低,表明空间异质性同样是影响两种捕食性天敌捕食作用的一个重要因素 |
