Air permeability of field soil was obtained k1=4.8446×10^(-12)m^2 by soil column method. Meanwhile, relative permeability curve of air-water was gained by biphase flowing experiment. During experiment period, average of soil water content was 0.2689g and pH value was 7.0-8.5. The quantity of aboriginal animalcule went down sharply after pouring contamination into the ground and then rose gradually to its original level which was 10^7 (unit g1dry soil).

Methods The pesticides were extracted with acetone and dichloromethane, warmed with water at 40℃,and circumrotated and evaporated until it was nearly dry, then it was purified by Envi Carb column and Sep Pak NH2 column. Afterwards, gas chromatography mass spectrometry and selected ion monitoring were used to determine 42 pesticide residues, such as organo-phosphorus, pyrethroid, organochlorine, carbamate and weedicide.

Results demonstrate that the Cu(superscript 2+) can be concentrated effectively under the following condition: exchange column internal diameter 0.8 cm and 15 cm high, the dosage of spiral algae 2 g and pH value 6, the flow rate of the dry food leach solution 10 mL/min, elute with 0.6 mol/L HCl at a flow-rate of 6 mL/min.

结果表明，在交换柱内径为0.8 cm、柱高为15 cm、螺旋藻用量为2 g、pH值6的条件下，干制品浸出液流速为10 mL/min时，用0.6 mol/L HCl以6 mL/min的速度洗脱，可对Cu(上标 2+)进行高效富集。

Quercetin, quercetin rhamnoside, hyperin, syringoside and eleutheroside E wereisolated from the flower of Acanthopanax senticosus. Searching bioactive natural compound and establishing quality evaluation standard arefocused on this experiment. Using cold immersing of 70% methanol to extract from flower ofAcanthopanax senticosus and integrating macroporous resin, silica gel column chromatography,sephadex gel to abstract. We obtained five monomer compounds (compoundⅠ-compoundⅤ),quercetin, quercetin rhamnoside, hyperin, syringoside and eleutheroside E. That five compoundswere determined by HPLC in eight parts of Acanthopanax senticosus (flower, root, leaf fruit,shoot, new shoot, phloem of shoot, skin of shoot), which provide science bases for establishingquality evaluation system and settle infarctate foundation.
