查询词典 trace element

Trace Ru could sensitively catalyze the fading reaction of chlorosulphophenol azo rhodanine with KClO3 in H2SO4 medium in water bath at 85 ℃, and the fading level was in direct proportion to Ru in certain content range. Based on this, a novel determination method of trace ruthenium was established by catalytic kinetic spectrophotometry.

Li-lei get the understanding of the mysteries of the "Tao", the profundities of the "Dhyana", and knew well the mystery of the theory of One painting. By the spirit of being above worldly considerations, he upgraded his artistic conception, looked the "painting trace" as the record of the "heart trace", integrated the painting meaning with the poet meaning, as well as improved the rational "Tao" and the Dhyana to the stage of poet. All these could be regard as the "mixture of emotion and rationality" in Li-lei's abstract art creation.
