The invention discloses a tool for measuring the operation efficiency of a business flow. The tool is characterized in that each function of an EPC (event-driven process chains) tool has an enhanced attribute representing the function execution probability, i.e., each function has an additional attribute parameter representing a function execution speed; the operation efficiency measurement of a flow represented by an EPPC tool is carried out by constructing a Markov chain for the business flow constructed by the EPPC tool, and analyzing the key index of the flow operation efficiency based on the stationary probability of the Markov chain. Compared with the common EPC tool and extension, the EPPC tool has the following advantages: the actual representation ability of the existing EPC tool is enhanced; the EPPC tool can be used for evaluating the performance of the business flow so as to find the efficiency bottleneck problem existing in the business flow of enterprises; and the EPPC tool ...

The invention discloses a method for a manufacturing gradient copper-wolfram/copper-chromium zirconium bronze integrated contact. The method comprises the following steps of: carrying out compression moulding, sintering and infiltrating on copper-wolfram power in different proportions in sequence; then connecting a copper-chromium zirconium bronze conducting rod by using a sintering process to finally obtain the finished gradient copper-wolfram/copper-chromium zirconium bronze integrated contact. The gradient copper-wolfram/copper-chromium zirconium bronze integrated contact manufactured by using the method has the advantages of good heat conductivity, electrical conductivity and bonding strength, can better satisfy the requirement of a high-voltage and ultrahigh-voltage switch on the integrated contact and has a wide market application prospect.
