On the basis of calculation and analysis of statistical parameters of measured monthly rainfall sequences of thirty-three years in Guangzhou area, performs logarithmic transformation of the monthly rainfall sequences, and develops a stochastic simulation model of monthly rainfall by the first order AR(P) model.

A new image fusion method is proposed on the basis of combining Brovey transform with logarithmic transformation for intensity modulation.

A method proposed in this paper avoids the log-transformation in view of its drawbacks,specially the log-ratio transformation,but normalizes the data after background correction.

Research on conversion factor for strength class of partial components of mass concrete;

Shenyang area mortar strength conversion factor's contrast summary rests on the new old testing method to obtain

[Objective] The aim of this study was to estimate conversion factors between different sampling methods by comparison between Chinese and US dust monitoring methods.

The meanings of the conversion coefficient of gamm.

This paper provides the conversion coefficient of compressive s trength between 70mm cubic test piece and core test piece with diameter of 70mm by making comparisons between compressive strength of these two kind of test pie ces.

Based on laboratory model tests, it is considered to be suitable to select a conversion coefficient 0.
