As to the upconversion material assured, the single and definitive conversionspectrum can be got when the adapted optical pumping source is selected.
对于确定的上转换材料，当选用恰当的激发光源进行激发时，可得到唯一确定的转换光谱；

A method for deriving the smoothed ground surface from CMP datum of static correction is given to form a common datum for velocity spectrum, time-depth conversion and depth migration in depth domain.
Finally, a methodology converting response spectrum of design earthquake to seismic intensity is also discussed; and a conversion scheme is recommended.
