One is model reference fuzzy adaptive control system, in which the fuzzy logic inference is used in adaptive algorithm. So it solves the problem of complicated adaptive algorithm in conventional model reference adaptive control system. It raises system's stability.

Full exhibition of incomplete ionization of dopant from 300K to 600K under the condition of weak electronic field results in different characteristics from those of conventional model.

Conventional model monitoring methods have many disadvantages such as complication of device or sensor installation,much hard work,limitation in sampling points etc. Here,we propose a method using computer vision and digital close-range photogrammetry technique to monitor model deformation.

Conventional model calculation method is time-consuming and has greatly hindered the development of simulation and optimization of an oilfield water flooding system.

Conventional model calculation method consumes plentiful time and has seriously hindered the development of simulation and optimization of oilfield water flooding system.

The results indicate that the difference between the prediction error of the orthogonal model and that of the conventional model is less than 0.02g/100g. For these two models, the discrepancy between the predicted concentration and the reference concentration is about 0.1g/100g.

Model LC 152 coring tool is selected for the coring job in this well, and as compared with the conventional model of 250P,it has the unique inner outer mandrel centralizing function, and the average coring recovery rate reaches to 94.9%.

The linear autoregression model with input variables is a comprehensive forecasting model which is superior to the conventional model for phenological forecast.

Based on artificial rain tests performed on the upper Yellow River from April to September of 1997 and 1998, a hydrologic runoff model is applied to the evaluation of the effect of artificial rain, and the result is found to be more reasonable and reliable than that of the conventional model.

The resulting model catalysts are remarkably stable against sintering, a major problem of conventional model catalysts when exposed to elevated temperatures and oxidizing gas atmosphere.

The models considered are a variant of the flypaper model (see, for example, Courant et al., 1979 and Oates, 1979) and a conventional model which builds on the seminal work of Wilde (1969, 1971).

The proposed model and estimation differ from the conventional model of Aigner, Lovell, and Schmidt.

Unlike the conventional model with a derivative, the integral model admits a smooth state transition of two point centers into the state of a single center by the reduction of the distance between the centers down to zero.

The fluorescence characteristics in 2-octanol (η = 7.29 cP) are readily explained by the conventional model of excited-state relaxation kinetics by solvent reorientation.

According to the method of angular power spectrum for average sound field in shallow water, the transformation relation between arbitrary angle dependence of bottom scattering and the range dependence of long-range reverberation in shallow water homogeneous layer is established. As compared with the conventional model of boundary reverberation at short-range in deep sea, a multipath factor will be added. By using the transformation relation, the bottom baekscattering strength for the frequency band of...

According to the method of angular power spectrum for average sound field in shallow water, the transformation relation between arbitrary angle dependence of bottom scattering and the range dependence of long-range reverberation in shallow water homogeneous layer is established. As compared with the conventional model of boundary reverberation at short-range in deep sea, a multipath factor will be added. By using the transformation relation, the bottom baekscattering strength for the frequency band of 0.8-4.0 kHz and grazing angle range of 2-10 has been derived from shallow-water reverberation data at five locations in the Yellow Sea, the Bohai Sea and the East China Sea. It is shown that the bottom scattering constant (u) and angle index (2n) for high speed sediment of continental shelf depend not only on sea area and frequency, but also on angle range. For very low grazing angle the decay of bottom baekscattering strength with decreasing grazing angle is. more rapid than that for mediate grazing angle.

The effective diffusivities of hydrogen, nitrogen and argon in B_(106) and B_(109) carbon shift catalyst pellets at 30℃ and atmospheric pressure have been measured in a self-designed apparatus. The pore-size distributions of the catalysts have also been determined. The experimental results indicate that the controlling mode of diffusion in these shift catalyst pellets at atmospheric pressure was Knudsen diffusion. Two conventional models for evaluation the effective diffusivities are compared by estimating...

The effective diffusivities of hydrogen, nitrogen and argon in B_(106) and B_(109) carbon shift catalyst pellets at 30℃ and atmospheric pressure have been measured in a self-designed apparatus. The pore-size distributions of the catalysts have also been determined. The experimental results indicate that the controlling mode of diffusion in these shift catalyst pellets at atmospheric pressure was Knudsen diffusion. Two conventional models for evaluation the effective diffusivities are compared by estimating the tortuosity factor, and it is shown that the parallelpath pore model is suitable both for B_(106) and B_(109) shift catalyst pellets.

A dividing-layer model was developed to describe the atmospheric pollutants transport and diffusion in a vertical shear wind field and the dividing layer was defined as a layer on two sides of which wind fields are different. When pollutants from a real source arrive at one side of the layer, they will transport across it only by vertical diffusion and the flux then can be looked as a new source for the other side of the layer. In the case that wind fields on both sides of the layer were same, the solution of...

A dividing-layer model was developed to describe the atmospheric pollutants transport and diffusion in a vertical shear wind field and the dividing layer was defined as a layer on two sides of which wind fields are different. When pollutants from a real source arrive at one side of the layer, they will transport across it only by vertical diffusion and the flux then can be looked as a new source for the other side of the layer. In the case that wind fields on both sides of the layer were same, the solution of the model was similar to that of conventional model and when wind fields were different, the model revealed that the lateral distribution range of pollutant was larger than usual and the ground concentration central line gradually leaned towards the leeward of the lower layer wind.
