Domestic scholars generally call their theory incomplete contract theory or incomplete contract theory, because the theory is ba^ed on the following analytical framework： They use the incompleteness of contracts for research as starting point to property or （ residual ） optimal control with Ge for research purposes. It is the most important analytical tool for analyze business theory and corporate governance structures with Ge control incentives to obtain the information. GHM model directly inherit the transaction cost theory by Coase, and Williamson, and it is a critical development.

The thermal model can accurately estimate the device temperature, which is linearly with electrical input power. The simulation results show that there is almost no temperature gradient within the OLED device working under steady state conditions. Furthermore, thermal analysis simulation results show that the surface properties （convective heat transfer coetficient and surface emissivity） of the substrate or cathode can significantly affect the temperature distribution of the OLED.展开更多

The ignorance of fluid structure interaction （FSI） means that the energy transfer between fluid and structure is neglected. To some extent, the accuracy and reliability of unsteady flow and rotor deflection analysis should be affected by this interaction mechanism. In this paper, a combined calculation between two executables for turbulent flow and vibrating structure was established using two-way coupling method to study the effect of FSI. Pressure distributions, radial forces, rotor deflection and equivalent stress are analyzed. The results show that the FSI effect to pressure distribution in flow field is complex. The pressure distribution is affected not only around impeller outlet where different variation trends of pressure values with and without FSI appear according to different relative positions between blade and cutwater, but also in the diffusion section of volute. Variation trends of peak values of radial force amplitude calculated with and without FSI are nearly same under high flow rate and designed conditions while the peak value with FSI is slightly smaller, and differently, the peak value with FSI is larger with low flow rate. In addition, the effect of FSI on the angle of radial force is quite complex, especially under 0.5Q condition. Fluctuation of radial deflection of the rotor has obvious four periods, of which the extent is relatively small under design condition and is relatively large under off-design condition. Finally, fluctuations of equivalent stress with time are obvious under different conditions, and stress value is small. The proposed research establishes the FSI calculation method for centrifugal pump analysis, and ensures the existing affect by fluid structure interaction.展开更多

Methods: A database of zang-fu syndromes was established. The relationship between the zang-fu syndromes was analyzed by means of frequency analysis, association rule, and ф-coefficient correlation. Results: The six zang-fu organs of the heart, liver, spleen, lung, kidney, and stomach prove to be the main components of the zang-fu pattern. The large intestine, small intestine, gallbladder, bladder, triple energizer, and pericardium have strong association and positive correlation with the above-mentioned six zang-fu organs, and their clinical symptoms can all be included into the symptoms of these six zang-fu organs. Conclusion: The traditional TCM pattern of six-zang and six-fu can be simplified into five-zang and one-fu.展开更多
