In this paper, based on the original data of landsat-5 TM in 1988, landsat-7 ETM+ in 1999 and 1 ' 250000 topographic map as the main information sources, by the method of remote sensing digital image processing, the author has extracted leading factors of soil and water loss, such as vegetation cover, land-use type, gully density, parent materials of soil, and so on.
For need of processing and pretreatment of high pulses field electric, equipment of high pulses field electric pretreatment firstly established, the voltage and pulses, frequency, pulses duration can controlled.
结合加工和高压脉冲电场(High pulses electric field简称HPEF)处理的需要,本文首先建立了一台可控电压、脉冲、频率、脉冲持续时间的高压脉冲处理实验装置。
Similarly, the activity of the cellulose enzymes reached a maximum value of 0.38 mg glucose/(g 24h) in the tenth day during the composting process using the substrate of mixed pig excrement and wheat straw with microorganism agent, and the treatment without microorganism agent had a maximum values of 0.335 mg glucose/g.
The computer has been applied to calculate and process absorptive data of spectrophotometric determinate microelements Cu,Zn,Mn,Fe in soil. The method is called CPA. It has been T -test, t value less than T 005,it's confidence level of probability is Cu2+>Fe2+>Mn2+>Zn2+.
The results of bioassay revealed that LC50 of ethyl formate was 28.65 μL/L with a 24 hours treatment at 25 ℃,and there was a significant decline in AChE specific activity of S.oryzae treated with sub-lethal concentration.
Through the operation test and economic analysis to the system, the results show that the death rate of the ascarid’s egg ≥95% and the number of the coliform ≤105/kg, and the treated feces was environmental friendly. The granular organic fertilizer has total nutrient content ≥5.0%, organic content ≥35% and moisture content ≤20%,and its every item is superior to the standard NY525-2002 of China.
