field-by-field form
1.When the time limit of the preference policies constituted by our country and our province is over, we will support all the items which are put into the support field by the government with fund in the form of finance payment, the abetting scope; the first 3 years not below 50% of the company income tax which turn in to county(engraft, reconstruct, rent, cooperate, annex, share, purchase, recompose the primary company, evaluate according to the new technology enterprises; the later 4 years, not below 30% for advanced and new technology enterprises.
4.In this case, the harmonic which is the higher flux density amplitude of two hamonics which are adjacent to main wave in the rotor field. is reduced by "borrow slot" methed adopted from stator winding,to meet the requirements of the voltage-form distortion rate and to avoid core vibration and noise caused by the harmonic field potential frequency which is approximation two times that of the network.
9.By using Fourier-Bessel integral transformation, the reflection electromagnetic field was expressed as an integral form in terms of the cylindrical wave function in continuous spectrum, that is, Sommerfeld type integral, so the reflection characteristic caused by any dipole source, theoretically, could be gained by using sum.
