    • The dilute support frame is made up of interphase longitude and latitude bars that preferably are hollow. The bars can be rectangular, rectangular with a rounded end, half-circular, triangular, polygonal or any combination thereof. The bars are sized to support the ion exchange resin in the dilute channel adjacent the concentrate membrane bag. The support frame also assures fluent water flow in the dilute channel. The support frames are arrayed on the membranes with interphase aisle to save the frame arrays and make water flow fluently. The membrane envelopes in turn with the support frames as both are preferably wound to form the cylinder module, and is covered by one plastic protecting net. This new type of support frame can assure fluent water flow in dilute channels and convenient resin filling.
    • 稀释的支撑框架由优选为中空的相间经纬线组成。 杆可以是矩形的,具有圆形端,半圆形,三角形,多边形或其任何组合的矩形。 这些条的尺寸被设计成支持邻近浓缩膜袋的稀释通道中的离子交换树脂。 支撑框架还保证了稀释通道中流畅的水流。 支撑框架通过相间通道排列在膜上,以节省框架阵列,并使水流畅流动。 薄膜依次包围支撑框架,两者都优选地被卷绕以形成气缸模块​​,并被一个塑料保护网覆盖。 这种新型支撑框架可以确保稀疏通道中的流动水流动,树脂填充方便。

    • An Explicit Congestion Notification (ECN) method is disclosed for wireless applications to avoid network congestion in a TCP/IP packet-switched network. Such method comprises transmitting, at a source node, data packets to a destination node, via at least an intermediate node; determining, at the intermediate node, if an incipient congestion is encountered, setting a Congestion Experienced (CE) flag in each data packet to notify congestion; sending, at the destination node, an ECN-Echo acknowledgment packet back to the source node to inform congestion; reducing, at the source node, a congestion window and a transmission rate to avoid congestion; if the packet loss is due to congestion, re-transmitting, at the source node, only a lost packet to the destination node; alternatively, if the packet loss is due to transmission error, re-transmitting, the lost packet to the destination node, while increasing a round-trip timeout but maintaining the same congestion window.
    • 针对无线应用公开了一种显式拥塞通知(ECN)方法,以避免TCP / IP分组交换网络中的网络拥塞。 这种方法包括经由至少中间节点在源节点将数据分组发送到目的地节点; 在中间节点处确定是否遇到初始拥塞,在每个数据分组中设置拥塞经验(CE)标志以通知拥塞; 在目的地节点处将ECN-Echo确认分组发送回源节点以通知拥塞; 在源节点减少拥塞窗口和传输速率以避免拥塞; 如果分组丢失是由于拥塞,则在源节点处仅将丢失的分组重新发送到目的地节点; 或者,如果分组丢失是由于传输错误,则将丢失分组重新发送到目的地节点,同时增加往返超时但保持相同的拥塞窗口。
