During the operation of HV (high voltage) motor, the abrasion of stator windings because of vibration caused by electromagnetic force will give rise to slot discharge. Furthermore, the superheat induced by overcurrent or poor heat dissipation will aggravate the slot discharge. To understand the effect of different temperatures on slot discharge, two laboratory experiments, under different temperatures, were carried out to simulate the slot discharge for 120h. The experiment results indicate that the temperature greatly promotes the development of the slot discharge.

Achieve the equalization of public services must rely on fiscal transfer payment. China's transfer payment system has some defects such as the size of general transfer payments is too small, Transfer payment system has significant revenue sharing features and has significant inverse equalization effect. China's government should learn from the western developed countries and reform the transfer payment system in order to prompt the equalization of public services, make a clear division of governments' responsibilities, formulate a law and make good use of the horizontal transfer payment may be some good suggestions for China's government.
