+<p><code><strong>RTCPeerConnection.removeStream()</strong></code> 方法用来移除本地音频或视频的 {{domxref("媒体流")}} 。 如果已经发生交互，远程主机可能需要使用一个新的媒体流。</p>
+
+<p>当 {{domxref("RTCPeerConnection.signalingState", "signalingState")}} 的值为<code>"closed"时，将抛出</code><code>InvalidStateError异常。当</code>  {{domxref("RTCPeerConnection.signalingState", "signalingState")}} 值为<code>"stable"时，</code> 将触发{{domxref("RTCPeerConnection")}}的 {{event("negotiationneeded")}} 事件。</p>
