研究了各种系统的路径积分模拟的广义Trotter公式的一种方便形式，并证明比原始形式好得多。用新方法求解了氢原子问题，但结果并不完全令人满意。
A convenient form of the generalized Trotter formula for path‐integral simulations has been investigated for various systems and proves to be much better than the primitive. The hydrogen atom, which is pathological for the primitive algorithm, is solved by the new method but the results are not completely satisfactory.
