>Who can tell me how diffrence between 802.1ad and 802.3ad??

Search engines are your friends! I found the following information in about
30 seconds worth of searching with Google.

802.1ad Provider Bridges 

This standard builds on the IEEEs 802.1Q (Virtual LANs) to enable stacked
VLANs (see Smooth Sailing for VLAN Standard ), commonly referred to as
Q-in-Q tag stacking, a vital tool for service providers. With stacked
VLANs, customers traffic is tagged with a service provider VLAN at the
provider edge, allowing significant scalability of switched Ethernet service
provider infrastructure, and separating subscriber spanning tree restoration
from the service providers protection methods. In addition, 802.1ad will
allow Layer 2 control protocol tunneling. Moving forward, 802.1ad will be a
component of VPLS. 

Link Aggregation Control Protocol (LACP) is part of an IEEE specification
(802.3ad) that allows you to bundle several physical ports together to form
a single logical channel. LACP allows a switch to negotiate an automatic
bundle by sending LACP packets to the peer. It performs a similar function
as Port Aggregation Protocol (PAgP) with Cisco EtherChannel.
