    摘要： The present invention provides aqueous viscoelastic compositions comprising a cleavable anionic surfactant which is a sulphonate and possibly also an electrolyte. The cleavable surfactants useful in the present invention comprise a chemical bond, which is capable of being broken under appropriate conditions, to produce oil soluble and water soluble products typically having no interfacial properties and surface activity compared with the original surfactant molecule. Further, the rheological properties of the aqueous viscoelastic composition are usually altered upon cleavage of the cleavable surfactant generally resulting in the elimination of the viscosifying, viscoelastic and surfactant properties of the composition. Aqueous viscoelastic compositions in accordance with the present invention are suitable for use in oil-field applications, particularly for hydraulic fracturing of subterranean formations. Thus, the present invention also relates to a wellbore service fluid and a method of fracturing a subterranean formation.

    摘要： An invoking request processing method in distributed system. The method makes a judgment according to the interface performance of an invoking object, and transforming an invoking request being sent to an intermediate object into a transferring request, which makes the intermediate object only needing to perform the transferring operation for the invoking request. The actual implemental object directly returns the result to the requesting party. And an corresponding distributed system, distributed server and object implementing module are provided. The requesting party may directly obtain the implement result from the actual implemental object by launching only one invocation, which enhanced the requesting efficiency. Meanwhile the intermediate object only needs to implement the transferring interface, which simplifies the development difficulty of the intermediate object.
