| As the Popularize application of Wireless mobile network and Ipv6, we will face a environment of seamless computing and collaboration which are immaculate. We realise the overall sharing and coordinated managementses of calculate resource, Store resource, Data resource, information resource, software resource, communication resource, valuable scientific instrument resource and knowledge resource by a" virtual super computer" which is organized with the computers, the industry equipments and scientific instruments dispersed in different geographical position through internet. "The dynamic composition of virtual process" is the core mechanism of this environment.This paper has put forward a piece of clear and intact fictitious mechanism of dynamic composition of virtual process based on Web Services Stacks , and face the software development approach served. Utilize operation principle of this mechanism of description with detailed example of an online dictionary at the same time , this makes sense ont only to the whole theoretic framework for services composition but also to its practical application in industry. This paper still provides the detailed designs and realizing of some important components in this mechanism: UDDI registration center and SOAP platform. ?Finally, direct against the weak point of this mechanism 桱ust a semi- automatic mechanism. This paper proposes and passes the concept which introduces semanteme Web, propose one UDDI registration center that semanteme strengthen come automatic discovery served to realize, thus reach the full-automation of the whole mechanism.It can realizes "The heavy may use legacy systems in order to protect existing investment; Promote the technical level of the developing system by a large margin in order to keep the system' s advance within 5~10 years; Guarantee the evolution of the system which is according the customer requirement and the environment through a growable software architechture."...
