When lignin was removed,wet and dry steaming(151℃,0.4MPa,10min),H2O2 treatment(pH=11.6,45℃,10min),the extracting rates of soluble dietary fiber were separately 12.14%,11.52% and 11.48%.
With successivecoagulation-sedimentation-sand-filtration treatment(15mg/L Al2O3), the CODCr,BOD5 and SS was 23~34mg/L, 6.44~10.26mg/L and 5.1~7.8 mg/L, respectively ; NH3-N was less than 10mg/L ;
A deformation-aging treatment(850℃,900℃ quenching+550℃ rolling 25%, 50%+580℃ aging) and a stabilization treatment(350℃, 450℃, 10-100h age) of Ti-6Al-4V alloy were made successively.
In the second part, where we explore connections with Maxwell's equations, the main novelty is the treatment of the corresponding electro-magnetic boundary value problem by recasting it as a 'half' Dirichlet problem for a suitable Dirac operator.
Analysis of the low frequency response of automatic balancing D-C amplifier with mechanical chopper is illustrated by a typical circuit in this paper. The analysis of dynamic response of the modulation and the demodulation circuits and the auxiliary carrier wave amplifier have been considered more in details. The analysis is based on solving difference equations since the intrinsic working process behaved by the M-D M circuits using mechanical chopper is more accurately described by difference equation othe...
1.Homo-ionic colloidal clays (Mg-clay>H-clay>Be-clay>NH4-clay>K-clay>Na-clay. 3.The collcidal clays from yellow earth having lower SiO_2/R_2O_3 ratios fix more phosphate than that from purple b...
The rice stem borer, Chilo simplex Bulter, is one of the important rice pestsin Kiangsi. The relative proportion of this borer to Schoenobius incertellus Wk. isgradually increased especially after developing the movement of "Control the RiceBorer by Plowing in Autumn, Winter and Early Spring." This situation induced usto take up this problem. This paper deals with the distribution of the borer Chilo simplex with a dis-cussion of the factors influencing its distributional population. in Kiangsi. The lifehist...
