摘要：The micro structures and reflectance spectra of angiosperm leaves were compared with those of angiosperm petals. The study indicated that angiosperm leaf organs had identical micro structures and reflectance characteristics in the wave band of near infrared. Micro structures and compositions of leaf organs were the crucial factors influencing their reflectance spectra. The model of biomimetic materials based on angiosperm leaf organs was introduced and verified. From 300 to 2600 nm, the similarity coefficients of reflectance spectra of the foam containing water and Platanus Orientalis Linn. leaves were all above 0.969. The biomimetic camou- flage material exhibited almost the same reflectance spectra with those of green leaves in ultraviolet, visible and near infrared wave bands. And its "concolor and conspectrum" effect might take on reconnaissance of hyperspectral and ultra hy- perspectral imaging.

摘要：81.25 MHz射频四极加速器(RFQ)是低能量强流高电荷态离子加速器装置(leaf)的关键设备,为保障RFQ加速器的稳定运行和高质量出束,要求RFQ腔体达到10-6 Pa的超高真空环境。本文采用二级分子泵方案完成了leaf RFQ的真空系统设计,详细介绍了真空系统设计及设备选型流程,并使用VAKTRAK和MOLFLOW+软件分别对设计方案进行了模拟计算。目前,leaf RFQ平稳高效运行,实际测量真空度在1.4×10^(-6)Pa左右,满足供束和实验的要求。本工作验证了VAKTRAK和MOLFLOW+计算结果的可靠性,为强流重离子加速器装置(HIAF)真空系统设计积累了经验。

摘要：烟粉虱Bemisia tabaci寄主范围广、适应性强,可通过直接取食、分泌蜜露和传播植物病毒危害蔬菜和园艺作物。目前,B型和Q型烟粉虱是国内发生的主要生物型,也是传播番茄黄化曲叶病毒(Tomato yellow leaf curl virus, TYLCV)的主要媒介。

摘要：1968年，Golden leaf香烟的广告贴到了莲花车队的赛车上，F1从此进入烧钱时代，不过也宣告了纯洁的F1岁月就此终结。2007赛季，沃达丰将选择迈凯轮-奔驰车队，抛弃法拉利。这是成熟的商业决策，但是毫无疑问，这也是F1复杂和无情的一个缩影。
