介绍30 m望远镜（TMT）的相关背景以及我国在TMT项目中承担的任务。从TMT三镜系统的总体要求出发，论述了三镜系统的两个主要部分（M3CA和M3PA）的具体要求、技术难点以及初步方案。针对M3CA，介绍了底支撑方案和侧支撑方案，采用Kinematic的底支撑方案时其面形精度RMS可以达到109.7 nm，SlopeRMS为0.95μrad，采用Kinematic的侧支撑方案时其面形精度RMS＜15 nm，一阶谐振频率等于17.7 Hz，均达到了设计要求。针对M3PA，介绍了Tilt轴系和Rotator轴系的方案。最后，简要介绍了三镜控制系统（M3CS）的要求和目标。

The background of Thirty Meter Telescope(TMT) and its mission that we should take in hand are introdced.The detailed specifications and the preliminary scheme for the M 3CA and M3PA in the 3 mirror (M3) system are presented according to the general specification .Then, the two parts,axial support and later-al support of M3CA, are designed in detail.Due to the kinematic concept design used in both of axial support and lateral support, the mirror surface error can be reduced in a acceptable level .When the kinematic axial support scheme is taken, its surface accuracy RMS is 109.7 nm and Slope RMS is 0.95μrad, while the kine-matic lateral support scheme is taken, its surface accuracy RMS is 15 nm,and the first natural frequency can reach to 17.7 Hz.The design proposal for M3PA is discussed and the control system for M3 system(M3CS) is introduced briefly.
