In addition, the choice of the finite basis set enhances the calculation efficiency to some extent, especially for simulating the PES associated with many potential surfaces. 另外，可以根據實(shí)際情況選擇一定個(gè)數的基矢和格點(diǎn)，在一定程度上提高了計算效率，特別是在計算模擬具有多個(gè)勢能面參與的光電子能譜時(shí)，其優(yōu)越性是顯而易見(jiàn)的。
The physical pattern of sediment exchange and bed coarsening simulation was put forward, and long-term data on hydraulic-dynamics and sediment motions were modeled. 提出了泥沙交換和河床粗化計算模擬的物理圖案，對長(cháng)系列水動(dòng)力和泥沙運動(dòng)進(jìn)行了?；幚?。
