A new type of the educational software for chemistry based on automatedreasoning with chemical knowledge was successfully developed. This intelligent systemwith the unique style of the interactive functions and the open mode of the knowledgebase has shown not only its notable ability to solve chemical problems, to improve thereasoning performance of itself, but also its advantages to provide more opportunities forthe users to acquire living knowledge through the interactive ways.

In this paper, a non-isotropic Jacobi pseudospectral method is proposed and its appli- cations are considered. Some results on the multi-dimensional Jacobi-gauss type interpolation and the related Bernstein-Jackson type inequalities are established, which play an important role in pseudospectral method. The pseudospectral method is applied to a twodimensional singular problem and a problem on axisymmetric domain. The convergence of proposed schemes is established. Numerical results demonstrate the efficiency of the proposed method.

A two-dimensional numerical model is constructed to study the interaction between the coastal upwelling and the coastal front off Zhejiang coast in summer. In the f-plane model, the shelf topography, continuous stratification, and Richardson number-dependent eddy coefficients are considered. The results show that the coastal up-welling off Zhejiang in summer can be divided into two regions, the nearshore one (Region A) and the offshore one (Region B). In Region A, the alongshore wind stress has more important effect on the coastal upwelling while in Region B, the upwelling is mainly induced by the Taiwan Warm Current. The results also suggest that the formation of coastal front off Zhejiang in summer is closely related to the strength of the coastal upwelling in Region A.

Chemical equilibria involving 10 species and adiabatic reaction temperatureof methane combustion in air under various conditions have been calculated in detail by means oftotal gibbs energy minimization of the system. The calculation data show that the adiabaticcombustion temperature of CH_4 and air at stoichiometric ratio is up to about 2200 K, and theequilibrium concentration of NO is about 0.0018, however that of NO2 is only 1 x 10^(-6). A largeamount of carbon deposition emerges when the CH_4 concentration is above 26.5%. The NO and NO_2appear only when the CH_4 concentration is below 16%. The maximum equilibrium concentrations of NOand NO_2 are 0.0028 and 2 x 10^(-6) respectively, at about 8%CH_4 concentration. The NO and NO_4concentrations increase with the system temperature at a low CH_4 concentration. However, both ofthem can be decreased when CO_2 or steam is introduced into the system, which also decreases theadiabatic combustion temperature. The decrease in adiabatic temperature caused by CO_2 addition ismore appreciable than that caused by the addition of H_2O. Pressure does not have a notable effecton the system equilibrium at a low methane concentration.
