10kV, Vi=+10kV, Vj=-10kV, Vk=+10kV, Vl=-10kV, Vm=+10kV, Vn=-10kV；Each segment length of pipeline is
Lab=10cm, Lcd=10cm, Lef=10cm, Lgh=20cm, Lij=10cm, Lkl=10cm, Lmn=10cm, then each section of pipeline
Electrical potential difference or induction field intensity are respectively Eab=2kV/cm, Ecd=2kV/cm, Eef=2kV/cm, Egh=1kV/cm, Eij=
2kV/cm, Ekl=2kV/cm, Emn=2kV/cm, reagent are all the reaction time for 18min by the time of the reaction system,
The product Peracetic acid of end reaction system outlet is entered in receiving flask 117, is then shut off alternating source 108, measuring pump 113
With 114 and thermostatic circulation bath 109；
Step 4：Control group processing is carried out, if above-mentioned other conditions all same, now above-mentioned classes of agents passes through reaction system
It is control group to unite but do not apply the sample that driving voltage obtains when primary coil 201.
Step 5：Through measurement, after processing, the Peracetic acid mass fraction point in induction field group and control group product
Wei 17.5% and 7.4%.This shows that after the induction field processing of the reaction system Peracetic acid in product has aobvious
The raising of work.
