We study phase separation of binary mixtures in the presence of mobile particles by the lattice Monte Carlo simulation. The presence of mobile particles changes
Resistance as a function of temperature for optimally doped manganese perovskites is simulated based on a random resistor network model which is generated throu
Single-layer polymer light-emitting diodes are prepared from blends of poly(N-vinylcarbozole) (PVK) doped with tris(8-hydroxy-quinoline) aluminium (Alqs) of 2wt
三年试验表明,三十烷醇对高粱确有增产效应,不论是浸种处理还是不同生育期整株喷施,都可以提高高粱产量。三年产量经方差分析,初花期喷施和浸种处理与对照差异均达极显著水准
In studying a 2-dimensional symplectic map, the exponential law and algebraic law are observed in the diffusion of orbits in the phase space. The diffusion time
目的 通过噬菌体随机七肽文库筛选出与体内肺癌组织特异结合的七肽,并制备肽类肺癌早期诊断试剂.方法 通过噬菌体展示体内筛选技术获得与肺癌特异结合的噬菌体,进行序列测定,合成特异结合的多肽,125I标记后经静脉注射入小鼠体内,观察其在小鼠Lewis肺癌模型中的分布.结果 通过4轮筛选获得了QYGQFAY七肽,该七肽经125I标记后可以很好地与肺癌组织特异结合,在体内2 h左右与肿瘤结合得最充分,而且体
Supercontinuum generation in atmospheric-pressure nitrogen by a focused intense femtosecond Ti: sapphire laser was studied at various pulse durations and energi
Composite arrays of multi-wall carbon nanotubes (MWNTs) and silicon nanowires (SiNWs) are fabricated by means of the chemical vapour deposition method in porous
一些植物有着神奇的灭虫能力,如万寿菊就是一种极好的天然灭虫药。万寿菊原产墨西哥,我国各地都有栽培,它那刺鼻的气味是一种奇妙的驱虫药。在花圃四周种上万寿菊,整个夏季,
