The skeleton tool offered a platform to build a prototype system, to program class code, and to develop the expert system. Four branch expert systems were developed using the skeleton tool including the control of chemical composition, the control of sintering process state, the control of expended energy, and the diagnosis of abnormity. It is found that the performance of all systems is satisfactory in practice.展开更多

Accordingly many meteorologists have researched the cause why the solar semidiurnal barometric oscillation is magnified and the solar diurnal barometric oscillation is suppressed at the ground.展开更多

Owing to the close relation between the chemical oscillatory reaction and the processes of biochemistry and physiology, etc., people have also realized the importance of oscillatory reactions, in which vitamin C（ascorbic acid, H2A） participates. Some of these reactions were performed under the same condition as that of the BZ reaction. In order to展开更多
