A new auditory system model based on a combination of physiological and psycho-logical acoustic data has been proposed. This model consists of a bank of nonuniform bandpassfilters, detectors and main-frequency choosing mechanisms, they act as basilar membranes, innerhair cells and nerve fibers, respectively. Combining with the improved critical bandwidth pa-rameters, the input to this model is analogous to the pressure at the eardrum, and the outputof this model simulates various features of the firing pattern. The synthesizer obtains the resul-tant speech by use of the simple adding method. Computer simulations show that the resultantspeech is highly intelligible and natural. The proposed model is correct and the improvement ofthe critical bandwidth parameters is effective.

A new urban water resources use and forecasting model consturcted by comprehensive considering the balance between the supply and demand of the water resources system to an industry city and the feedback relationship of the water resources control policy,and by applying DYNAMO language is presented in this *** can give more rational data of urban water resources simulation and planning than that given by the growth rate trend forecasting method.

The active intermediates of hexacoordinated 4-nitrotrispirophosphoric amino acid (P(6)-AA), which were formed by the reaction of 4-nitro-O,O-phenylene phosphochloridate (NOPPC) with silanizing serine, threonine and cysteine, were observed by 31P NMR spectra. The reaction mechanism of these processes was discussed. In addition, some interesting results were observed by mixing 4-nitro-2,2,2-tricloro-1,3,2-benzodioxaphosph(v)ole (NTB) with silanizing serine and histidine.
