In the paper we present ATM cell structure asynchronous time-division multiplex the function of adaptive layers service categories describe in detail the GFR service category and its comparison with other service categories and show service control in ATM Networks .

本文描述了ATM信元结构，异步 时分 复用，适配层的功能以及服务种类，详细讨论了GFR业务类型并与其他业务类型作比较，显示了其在ATM网络中的业务控制。

In time-division multiplex analog video signal system the chrominance signal may be compressed along the time axis with the modulated clock pulse by the luminance signal so that the frequencies of time-compressed signal become homogeneous .

在 时分 多路 复用（TDM）的信号系统中，用调制的取样脉冲沿时间轴压缩色度信号的同时，可使色度信号的频率匀化，从而克服信号的时间压缩与频带扩展的矛盾。
