send a duplicate to

基本解釋

Likewise, the receiving side must not only agree to send back an ACK once they receive a message, but they must ignore any duplicate messages.
同樣，接收方不僅要同意一旦收到消息，立刻返回一個 ACK，還必須忽略任何重復(fù)的消息。
Where there is a victim in the case, the public security organ shall send a duplicate of the written decision to the victim.
有被侵害人的，公安機(jī)關(guān)應(yīng)當(dāng)將決定書副本抄送被侵害人。
We understand that this news must be disappointing to receive and, for that reason, we will not send a duplicate notification of this decision by mail.
那啥，我知道這消息很讓人失望，所以，我們就不再刺激你了，你不會再收到紙質(zhì)通知的。
