The propagation of coherent and partially coherent light pulses through a one-dimensional photonic crystal ( 1DPC ) is investigated. The dependence of the evolution of the pulses inside the 1DPC on incident angles and the effect of the coherence of the pulses on the propagation properties are discussed. The evolution of a pulse inside the 1DPC is affected(More)
This paper aims to estimate the soil organic carbon (SOC) storage in North east of China, identify its balance situation and changing trends under current cropping systems, and finally put forward some strategies to keep the SOC in balance. A biogeochemical model (DNDC) for agro-ecosystem was employed to predict SOC dynamics in agricultural ecosystems at(More)
