AFD is the application of the risk analysis in I-TRIZ which is derived from the TRIZ. Stan Kaplan et al. created a template for AFD-1， used “resources” to remove the failures and make the system more idealized. However，there are so many kinds of resources， making the operation workload larger and the operation require higher professional ability of the performers. So the application of the AFD-1 template is difficult to use. We applied the conflict resolution theory of TRIZ to the AFD-1 template，used the theory instead of “resources” to remove the failures and optimize the design scheme, and then created a new AFD-1 template based on TRIZ conflict resolution theory. At last，application example was given，which showed that the new AFD-1 template can overcome the operational complexity of traditional template，reduce workload and greatly improve the practical application results．

In order to get a reasonable and effective adaptable structure design solution， fuzzy comprehensive evaluation method， technique for order preference by similarity to an ideal solution（TOPSIS） and grey correlation method were adopted to evaluate various schemes synthetically. The evaluation index was determined， the original data matrix was established， then weight coefficients of different index were fixed based on the theory of analytic hierarchy process（AHP）， according to the principle of adaptable design， comprehensive performance evaluation functions based on three methods were created， the characteristics of the three methods were summarized. A large vertical grinding machine beam design was taken as an example， the 12 kinds of forms were taken as evaluation targets， the Ansys Workbench software was used to do finite element analysis of dynamic， static and thermal performances of various beams. Programs were compiled to calculate evaluation results under the 3 methods， then the results were compared to determine optimal plan. Results show there are little differences among the 3 methods， and it is fitted to practical selected scheme. Through the comparison， we draw the conclusion: fuzzy comprehensive evaluation is optimal， followed by grey correlation method， TOPSIS method is the worst．

High precision machine tools are the fundamentals of micro machining. At present， in the design process of high precision machine tools， the accuracy of each axis is selected mainly based on designers'experience or intuitively from the accuracy requirements.

Components of each axis can be selected scientifically according to the research results in the design process. The introduced method also adapts to medium and largesized simultaneously multiaxis machine tools．

To meet the demands of large capacity and high parameters on 1000 MW ultrasupercritical pressure boiler feed pump， the numerical simulation of cavitation performances of boiler feed pump blades were carried out through CFD applications. A new design method of geometric profile parameters based on Bezier function was proposed. Two types of radial bending blades were introduced， i.e. forward curved blade and reversed curved blade. Results indicate that the NPSH （net positive suction head） of straight blade is 22.8 m， and the absolute error is 0.2 m. Compared with straight blade and forward curved blade， reversed curved blade has the best cavitation performances， and the NPSH is 22.3 m. The vapor firstly generates at pressure surface of forward curved blade near the leading edge， and the cavitation region of suction surface is the largest， but the reversed curved blade is opposite. There is a maximum pressure drop on the middle streamline of blade at the relative position of 0.2， which could lead to local fracture．

The micro-emulsified fuel is an ideal alternative oxygenous fuel for diesel engines due to its excellent combustion characteristics. Fueled with the microemulsified fuel， a diesel engine can give off remarkably lower harmful emissions， especially particulate. It is necessary to take into account instantaneous variations of the thermophysical parameters of blended fuels with temperature and pressure. For these reasons， we took the microemulsified ethanol-diesel fuel for example， using the empirical formulas to calculate thermophysical parameters of this blended fuel， including the specific heat capacity， viscosity， thermal conductivity and diffusion coefficient. And the effects of the temperature， pressure and ethanol content on the initial blended fuels condition were investigated. Results indicate that the enthalpy of vaporization and liquid thermal conductivity of the micro-emulsified ethanol-diesel fuel decrease，and liquid specific heat capacity and diffusion coefficient increase with the temperature rising. The diffusion coefficient decreases with the pressure rising. And the liquid specific heat capacity and diffusion coefficient increase with ethanol content rising at the initial blended fuel. The effects of ethanol content on liquid thermal conductivity are significantly dependent on the liquid temperature. The effect of ethanol content changes backward at certain liquid temperature. The increase of ethanol content can contribute to the evaporation of the micro-emulsified ethanol-diesel blended fuel．

And it can meet the synchronous control request of workpieces．

The general pressure of the grinding fluid in transferring process is 0.2~0.4 MPa. It will lead to excessive tool wear if the pressure is too high, and can not effectively wash away grinding if the pressure is too low. In order to achieve a constant grinding fluid supply pressure， a constant voltage supply system is needed. PLC and inverter were applied to achieve frequency conversion constant pressure supply of grinding fluid in the designed system. The automatic control of pump rotation and work frequency/variable frequency transformation were realized by PLC. The inverter with internal parameter adjustment function and the sensor of external pressure formed an adaptive PID closed loop control circuit， achieving frequency control of the pump motor. Field operation results show that the system can achieve frequency conversion constant pressure water supply at 0.3~0.33 MPa by setting the inverter internal parameters P2280=5 and P2285=10， and the pressure change can be stabilized within the range of -5%~+5%. The system has been stably operated over 3 years， and can meet the pressure requirements of grinding fluid．
