例句
- Three-step symplectic quantum propagation of wavepacket has been applied to study the photodissociation of methyl iodide.
三步量子辛算法进行波包演化被用于研究碘甲烷的光解。 - Why did Wilkinson keep the QR algorithm as a backup to a Laguerre-based method for the unsymmetric eigenproblem for at least two years after the appearance of QR?
早些年华人在计算数学领域里面占有一席之地是因为冯康院士独立于西方，创立了有限元方法，而后又提出辛算法。
