But what was really new is that Iran also responded positively to the procedure proposed by the 5+1 group. In the pre-negotiation phase, this means that Iran would agree not to install any new centrifuges, necessary for increasing the volume of uranium being enriched, while the 5+1 group would refrain from calling for new sanctions in the Security Council.
但是，真正具有新意的是伊朗对五加一小组提出的程序做出了积极反应。在谈判前阶段，这意味着伊朗将会同意不安装任何新的、提高铀浓缩量所必须的离心分离器。与此同时，五加一小组则不再要求安理会实行新制裁。
