Supported by the three periodic data of Chinese Resources and Environment Database,at the meantime updating the remote sensing data of land use information in Hubei province using the 2005 TM image,to calculate the provincial normalized coefficient of the year of 1995、2000 in Hubei province and study on different scales of normalized coefficients.

Based on Chinese Resources and Environment Database,the vegetation coverage index for each county and its provincial normalized coefficient of 1995 and 2000 of Hubei province are calculated.

We quantilatively analyzed the impact of the different data sources and normalized coefficient on evaluation result of the eco-environment quality.

Normalization coefficients of four kinds of raising and loweringoperators of an N-dimemsional hydrogen atom;

An approach for deriving the normalization coefficients of raising and lowering operators about primary quantum number of an k?dimensional hydrogen atom via the virial theorem and operator calculating was presented.

According to the engineering requirement for equivalent burn-in test for the ICs of compatible function with different process and design, the “normalized burn-in current” as the characteristic parameter of the equivalent burn-in tests i extracted, and the method to determine the equivalent burn-in signal is discussed as well.
