Try to apply the optimum experimental design to the utilization of wastes in building material industry. Using multicomponent regression analysis to the influences of various mixing ratios on the main properties of the mix, a mathematical model is developed by means of quadratic orthogonal design. The model comprises 5 indices, i.e. slump,workability and three compression strengths(kiln-out, 28 days after standard curing and 28 days after steam/standard curing). With optimal solution, analysis and apraisement...

Try to apply the optimum experimental design to the utilization of wastes in building material industry. Using multicomponent regression analysis to the influences of various mixing ratios on the main properties of the mix, a mathematical model is developed by means of quadratic orthogonal design. The model comprises 5 indices, i.e. slump,workability and three compression strengths(kiln-out, 28 days after standard curing and 28 days after steam/standard curing). With optimal solution, analysis and apraisement taken on, not only correct process parameters but also the optimal mixing ratio can automatically be given by computer as the indices change in value. Concrete output and quality can thus be successfully controlled and, in particular, such wastes as fly ash will be in prospect of reasonable utilization.

The developed noncontacting electronic temperature controller is completely composed of integrated circuits with SWF9 thermister as its sensor of temperature. On-off temperature difference is controlled by an operational amplifier. And time-base circuit NE555 is used to control a photocoupler MOC3022, which in turn triggers a triple-ended bidirectional diode thyristor. The change of voltage to the temperature, which is propotional to that of the resistance, is amplified by a DC amplifier with adjustable gain, so that the output voltage exactly equals to the temperature change in value. On using a 3 1/2-bit A/D converter 7170 and a common-anode LED, the temperature is digitally displayed.

The total kinetic energy budgets of an intense convection event occurred on the 1st March 1983 over the Pearl River delta in South China have been diagnostically studied in this paper by the use of operational observation data. The results show that the generation term is, for the time-area mean,a dominant source; The divergence of horizontal energy flux and sub-grid processes act as major sinks in the total energy balance. Almost all major budget terms peak their values in the upper tropospheric layer in which the high level southwesterly jet is located. It is also observed that a certain amount of kinetic energy is transported upwards from middle and lower layers to the upper troposphere by resolvable scale vertical motion and downwards by sub-grid processes. Major budget terms show substantial changes in value before and after the peak storm activity.
