Parties were first partitioned to form a tree, then n representations from n nodes which were children nodes of the corresponding father node in the above level agree on a group key in this round by invoking the BCP scheme.

群内成员先进行树结构的划分，每n个节点作为相应上一级节点的孩子节点，n个节点分别选定代表，n个代表通过调用协议BCP协商密钥得到本轮即相应父亲节点的子密钥，重复进行上述过程最终可以得到群组密钥。

When other factors are finable, 15L/h is the suitable amount of aeration.By analysis, the excessive aeration amount will destroy the capacity of sludge, and so decrease the removal efficiency of CODCr,and the 15L/h aeration amount is enouge for the demand of nitrification.

4蛭石应用于一级生物强化处理中，蛭石填料对有机物去除没有明显效果，但可以增加系统对氨氮去除能力，与对照组相比，高出30％多；吸附饱和后的蛭石，在活性污泥再生过程中，通过活性污泥的降解有机物，可去除较大部分的氨氮。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
