This paper studies the calibration of orifice plate meter and the fitting of performance curve of centrifuga pump as well as refined calculation of flow coefficient
According to the situation that the mechanism of action of the permanent magnetic actuator is sophisticated, the synchronous on-off's control is effected by multiform factor, the functional mode and the synchronous on-off's control are difficult to refined calculation, the fuzzy and expert intelligent identify rule system to judgement the functional mode of the electric network is put forward, the fuzzy neural network is applied to accurately control of the synchronous on-off.
The geological characteristics of Gudaoling Tunnel project in Ankang Railway are introduced. The mud jack parameters are determined and calculation process is introduced for pressure loss. Through refined calculation the minimum range of slip casting pump is determined.
The results show that test design scheme is correct and feasible, the VFD life submits to Weibull distribution, the life-stress relationship meets Arrhenius equation, and the refined calculation of accelerated parameters makes it sure that the VFD life at the normal working stress can be estimated in a short time.
Finally, the error cause and resolution is proved theoretically through the theoretical analysis and comparison research for several typical tensile strength formula, which provides theoretical grounds for refined calculation of rock tensile strength.
The refined calculation of topological relationships is the new requirement of practice and application,which represents the trend of the research on spatial relationship.
This paper deals with the equation of higher degree encountered frequently in ionization of polybasic acid and complexing balance for many people feel it difficult to solve it. The auther gets the placed interval of the value of f(x) signs revesal through experiment method and obtains the approximation of the refined calculation of the root through accumulated experimental method, the subtend method and the tangent method are the short cut of the accumulated experimental method.

Using finite element method to calculate the stress of stator coil head and colligation band of the alternator which suddenly occurs short circuit. Through dividing the coil and band into more than 8 000 three_dimensional elements and 11000 nodes, in association with the engineering example, the stresses of each region and the maximum stress point are calculated. Thereby a sort of refined calculation approach to solve this design puzzle is acquired.
