The doublet potential energy surfaces of [Si, C, S]+ and [Si, C, S]-systems were investigated by the DFT, QCISD, and CCSD(T) methods.
采用DFT,QCISD及CCSD(T)方法分别对二重态的[Si,C,S]+和[Si,C,S]-体系势能面进行理论计算,用QCISD/6-311+G(d)方法,在[Si,C,S]+和[Si,C,S]-体系中,我们分别得到了2个过渡态连接的3个稳定体和2个过渡态连接的4个稳定体,经热力学及动力学分析发现,[Si,C,S]+体系只有二重态线性的离子[Si—C—S]+可能稳定存在,而[Si,C,S]-体系有二重态线性的离子[Si—C—S]-和三元环c-[SiCS]-可能稳定存在。

“猎鹰”sfq2040

国产“猎鹰”采用了“悍马”的原装底盘,总体来说两车性能指标基本一样。最主要的是它的价格仅为进口悍马的1/3,而美国马能做到的,国产鹰也不在话下。
