When I teach any stroke, in particularly butterfly, I use the part method.
我在传授任何泳姿时都会将身体分为各个部分来讲解，教蝶泳时更是这样。

The butterfly-net data redistribution of spectral adjoint models is put forward. In this method, the communication overhead is decreased.
提出了伴随模式并行计算的蝶网数据重分配方法，所占开销较环形算法少。

Finally, based on the above algorithm we get the embedding method from the butterfly network to the optical ring network and we analyse the embedding congestion of it.
