作为农业发展的经济主体,农户起着至关重要的作用.我国当前的政府环境管理模式和体制对于农村环境污染的治理作用有限.尤其将广大农户排除在决策监督主体之外是最大的缺陷,而
Based on the Bayesian theorem, an empirical Baye method is discussed. A programming chart for mass spectrum fitting is suggested. Using this method to extract t
目的 探讨小细胞肺癌 (SCLC) 组织中巨噬细胞炎症蛋白3α (MIP-3α) 和CC趋化因子受体6 (CCR6) 表达与术后复发转移及预后的关系.方法 收集陕西省核工业215医院SCLC癌组织标
TiO2/ormosil films doped with kiton red have been prepared by the sol-gel method. Spectroscopic properties of the entrapped dye are studied by absorption and em
Using evolutionary population synthesis technique, we explore the behaviour of the integrated U - B, B- V, V - R and R- I colours, the integrated spectral energ
We find that, due to the quantum correlation between the electron and the field, the electronic energy becomes quantized also, manifesting the particle aspect o
In a recent issue of Chinese Physics Letters, Wang et al.[1] proposed a method for determining orientation of transition dipole moments of single molecules. The
The giant magnetoresistance (GMR) effect and magnetization curves of Cu80 Co20 granular thin films are studied and measured in a superparamagnetism temperature
19世纪末,美国西部的密苏里有一个坏孩子,他偷偷地向邻居家的窗户扔石头,还把死兔子装进桶里放到学校的火炉里烧烤,弄得臭气熏天.他9岁那年,父亲娶了继母,父亲告诉她要好好注
A fully consistent relativistic random-phase approximation is applied to study the systematic behaviour of the isovector giant dipole resonance of nuclei along
