查询词典 efficient estimator

The replacement of toxic and volatile organic solvents as reaction media or an efficient catalyst with environmentally acceptable alternatives are an area of tremendous importance in modern organic synthesis. Basing the review about solid-phase synthesis with simple separation, the liquid phase organic synthesis supported by the solution polyethylene glycol and the chemical reactions in the medium of PEG, herein we are going to study the synthesis of 1-amidoalkyl-2 -naphthols in presence of the solution catalyst or the solid catalyst and the synthesis of thiourea in PEG-400 medium.

The experiment data of paramecium from Gause was used to investigate the efficiency of the method. And the twelve nonlinear real examples from "Agricultural Experimental Statistics" written by Mo Huidong were used to compare the difference between results fit by the Excel and the linear transformation method, respectively. The result showed that the Excel fitting method is not only simple and efficient for the parameter estimation but can fit various complex nonlinear equations also.
