1.本试验采用高效液相色谱法测定加工番茄根、茎、叶中的酚酸,从测定结果来看,加工番茄内含有不同量的鞣酸、咖啡酸、香草酸、阿魏酸、苯甲酸、水杨酸和肉桂酸,这一结果与前人在
The numerical method of modes analysis and decomposition of the output signal in 3D electromagnetic particle-in-cell simulation is presented. By the method, mul
We arrange quantum mechanical operators (a?a)m in their normally ordered product forms by using Touchard polyno-mials. Moreover, we derive the anti-normally ord
We numerically solve the time-dependent Ginzburg-Landau equations for two-gap superconductors using the finite-element technique. The real-time simulation shows
LiCoO2 is one of the most important cathode materials for high energy density lithium ion batteries. The compressed behavior of LiCoO2 under high pressure has b
Graphene with a Dirac cone-like electronic structure has been extensively studied because of its novel transport properties and potential application for future
The extinction ratio and insertion loss of spatial light modulator are subject to the material problem,thus limiting its applications.One reflection-type silico
