input concentration
1.Model sensitivity analysis suggests that the sensitive significance of Crop-C to input parameters is in descending order of temperature,PAR,atmospheric CO2 concentration,soil nitrogen concentration,rate of nitrogen application and precipitation when the input parameters vary at-10% and 10%,respectively.
2.In this model ,some measured process parameters have been used as input and the quality-indices such as degree of esterification,concentration of carboxyl end groups,saponification value, DEG content as output. Thus it can provide the operator with timely product information.
3.and the integrated forecast model is suggested. Six meteorological factors, such as wind velocity, wind direction, relative humidity, cloud, average temperature, highest temperature, are selected as input variants. After two months forecast test, the results show mean relative error of O3 concentration between forecast value and actual value is 21.49%, correlate coefficient is 0.837. Artificial neural network is a effective method to forecast the O3 concentration.
4.For any aims in the cannon fire airspace it can automatically account the baseline revision quantity,input to the cannon automatically,made all the eight cannons pointing to the same aim,thus achieve the target of concentration on fire power.
5.The input SS concentrations were 21.76,37.04,45.09 and 71.18 mg/L,and the hydraulic retention time(HRT) of each concentration were 12,16,24 and 24 h. The removal rates of SS were 68.1%,71.7%,77.5% and 74.0%. The aquatic marcrophytes not only removed the SS,but also greatly improved the transparency of water.
6.The concentration of OCPs was higher in mangrove national natural protection area in the harbor, its DDTs pesticide mainly came from historical accumulation and a newly input of γ-HCH.
7.In the course of vinylon dissolution,yarn tension should be adjusted in time,concentration of vinylon dissolving in water should be taken attention,waste water should be exhausted and new hot water should be input.
