实验结果表明：以辛醇、辛醇残液和辛烯醛残液作为萃取剂，在废水pH值为1~3、萃取剂与废水的体积比为1∶(1~12)、温度为25~60℃条件下，对丁辛醇废水进行萃取处理，均可得到较好的处理效果，COD去除率可达83%~94%。

Firstly the Lie group description and method of seismic wave propagation in phase space is proposed, which is, in other words, symplectic group description and method for seismic wave propagation, since symplectic group is a Lie subgroup and symplectic method is a special Lie group method.

文中首先给出相空间中地震波的李群表述和算法，也即地震波的辛群表述和辛算法，辛群是李群的子群，辛算法是特殊的李群算法。

On the other hand,un-der appropriate boundary conditions,multisymplectic methods also conserve thethe sum of symplectic form on discrete space,and this shows that multisymplec-tie methods is the gneralization of symplectic methods and describe the systemmore essentially.

另一方面，在适当的边界条件下，多辛算法也保持离散空间上的辛形式和，因而多辛算法是辛算法的发展，它更深刻地反映了系统的本质。
