This paper studies the EM Radiation and shield of monopole handset with the extrapolation which is suitable for the Finite-Difference Time-Domain(FDTD).

Its technical process is introduced , and the long-term hydrostatic strength of pipe is determined by extrapolation using the failure data.

This article reviewed several extrapolations in risk assessment of toxicant,and com- pared their advantages and disadvantages.

Research on Fatigue Property of Annular Specimen of ABS/SBS under Different Stress by Extrapolation Method;

Einstein photoelectric equation and the extrapolation method of photoelectric effect experiment;

The paper presents a new method for short-term load forecasting, which applies cluster analysis technique of pattern recognition principle to calculate the similar coefficients between the future day and past days, then chooses the most similar days according to these coefficients and uses linear extrapolation method to predict the load of future day.

The method trace to the source of the voltage transformer detection installation based on high-voltage deduced method;

9% rated voltage when using the deduced method test errors of voltage transformers, and it is validated through corresponding experimentation.
