The invention relates to a method for preparing endogenetic particle reinforced metal matrix composites under the coupling effect of a magnetic field and supersonic waves. The method comprises: adjusting the temperature of a metal matrix fused mass to the reaction initial temperature after refining, adding a reactant which can generate a particle phase with the fused mass through the reaction in situ for implementing the synthesis reaction, standing the mixture after the reaction is over, and cooling the mixture to the pouring temperature for pouring; and the method is characterized in that: the magnetic field and the high-intensity ultrasonic field are simultaneously exerted in the reaction synthesis process to realize the synthesis of endogenetic particle reinforced metal matrix composites under the coupling effect of the magnetic field and the high-intensity ultrasonic field. The magnetic field can be an intense pulse magnetic field, a high frequency oscillation magnetic field or a low frequency alternating magnetic field. In the method, the coupling effect of the magnetic field and the ultrasonic field makes the particle sizes be thinned and dispersed evenly; the ultrasonic vibration agitation and electromagnetic stirring functions improve the composite dynamic condition, and the compounding of the particle phase and a base metal interface is better; and the co-action of magnetochemistry and sonochemistry improves the thermodynamic condition of the reaction in situ, as well as speeding up the reaction in situ and controlling the growth of the particle phase.

This invention discloses a method which can realize the measuring example running automatically, firstly the state of section point is set, and the state section point can assemble into a state tree according to the execution way. Secondly, the transfer functions and process element of any two sections will be founded and stored in the real phase tree. During the realization of testing example, the start and end state are the state of the tree which separately sets to the prepositive and postposition condition. When multi testing examples are running, after one example finishes, the process element can take the finish phase of the testing example as the start of the conversion, and the start phase of the fellow example takes as the end of conversion and transfers the corresponding function to accomplish the conversion, then the next testing example is executed. This invention can realize the automatically control of testing example, and the setup is agility and does not need more maintenance.

The invention discloses a method, device and system for storing and reading a catalogue index and belongs to the technical field of computers. The method for storing the catalogue index includes the steps that identifiers are configured to all catalogues in the catalogue index; the catalogue index is split according to the identifiers of the catalogues, and catalogue split items corresponding to the catalogue identifiers are obtained; each catalogue split item and the corresponding catalogue identifier of the catalogue split item serve as one record item to be stored, wherein each catalogue split item at least comprises a corresponding sub catalogue identifier and a corresponding file storage address. According to the method, device and system for storing and reading the catalogue index, the identifiers are configured to all the catalogues in the catalogue index, the catalogue index is split according to all the catalogue identifiers, after the catalogue split items corresponding to the catalogue identifiers are obtained, and each catalogue split item and the corresponding catalogue identifier of the catalogue split item serve as one record item to be stored. Thus, the granularity of the catalogue index is refined, and therefore the access performance of the catalogue index is improved.
