A dipole structure anomaly in summer Arctic atmospheric variability is identified in this study, which is characterized by the second mode of empirical orthogonal function (EOF) analysis of summer monthly mean sea lev...
A sea temperature data assimilation system forthe China Seas and adjacent areas is developed based on anested regional ocean circulation model and variational op-timal interpolation assimilation method. A 12-year assi...

Novel low dipole moment (μ) and large first hyperpolarizability (β) electrooptic chromophores have been designed based on the special characteristic of reversed dipole moment in the excited state of exocyclic double...
Semiempirical quantum chemistry method AM1 was employed to calculate dipole moment of perylenequinone (PQ) in intramolecular proton transfer (IPT) process. It was found that there existed a maximum of dipole moment in...
NITROGEN is the most abundant element in the earth’s atmosphere. The study of optical oscillator strengths of nitrogen is of great significance in atmosphere physics, space physics and environment science. These resu...
