长连接,指在一个连接上可以连续发送多个数据包,在连接保持期间,如果没有数据包发送,需要双方发链路检测包。
然而,长连接并不是没有任何问题。
However, long-running connections aren't without their problems.
本操作仅适用于通信双方采用长连接通信方式时用于保持连接。
The operation is only used to maintain a long connection between two communication parties.
另外,这两个协议都能够建立长连接,事件可以通过长连接异步地递送给应用。
In addition, both can set up long-running connections such that events can be delivered asynchronously subsequently to the application.
So what's going to form the backbone is this continual link, phosphate to sugar, phosphate to sugar, phosphate to sugar, all linked together to form one long, long molecule.
主链是由这样重复的连接构成的,从磷酸到戊糖,周而复始,所有这些连接起来构成一个长链分子
This is - what this diagram shows you is-- the forces that hold these individual strands of DNA into a double stranded form.
你们可以看看这个图表,演示了连接两条DNA长链为双螺旋,结构的化学力
