In this review,the recent research developments of the common molecular ligands,such as citrate,thiols,surfactants,dendrimers and biomolecules used in the preparation and surface modification of gold nanocrystals are summarized.

Based on the precedence matrix among parts in the lowest level,algorithms to detect and verify the serial sub-assembly as well as parallel sub-assembly were developed.

Meanwhile,based on the information of the function structural tree and its parts of the production,the sub-assembly was judged by dividing the assembly relation graph and matching the rule.

The research on subassembly detection in assembly sequence plan;

Facing to the difficulties in manual judging subassembly unstability that usually appears in assembly process planning,unstability discrimination and clamping scheme selection were provided to help engineers to plan the assembly process of subassembly.

The algorithm of the subassembly division is proposed according to subassembly definition and matrix expression for the assembly structural information.

After the calculation of ZFS parameter of Cd12::V2+ , its results indicates that I-11s (A kind of ligand ion of large spin-orbit coupling coefficient) contribution to ZFS parameter can't be ignored, the classical crystal field model is only similar to dispin-orbit coupling coefficient model under certain circumstances, the calculation result .
