99Tcm-HYNIC-β-Ala-BBN(7-14)NH2 is prepared by choosing Tricine and EDDA as coligands,and the in vitro stability and biodistribution are compared for the two compounds.

At first,the reason of spacecraft distributed collaborative configuration is analyzed,and product configuration service which is the foundation of distributed collaborative configuration is presented,and then the process of distributed collaborative configuration is illustrated with the characters of Multi Agent and Web Service.

Currently, due to the privacy of policy of Internet Service Providers (ISP) and flaws of design and realization of Boarder Gateway Protocol (BGP), there are a lot of flaws in collaborative configuration and security, along with apparent deficiency to deal with the problems just like conflict in routing policy and routing cheating.

Research on component-based collaborative assembly technology for virtual prototype unit;

Method for master-model-based collaborative assembly in network environment;

Data compression of shared product model in synchronous collaborative assembly;

Research on resource co-allocation model in the grid;

Based on grid resources co-allocation system model,a novel strategy called synchronous queuing(SQ) is proposed for implementing co-allocation with QoS assurances in Grids.

Advance reservation(AR), co-reservation and co-allocation(co-scheduling) constitute the main body of Grid resource reservation system.

In this paper,a new method of collaborative allocation(CA) was proposed to solve large-scale optimum allocation problems in aircraft conceptual design.
