Study on the self-crosslinked acrylate cathodic electro-deposition paint with a high solid mass fraction;

The optimum production parameters are:solid-phase mass 40%,spray granulation ro.

The influences of PU mass fraction and the time of repose on the moisture vapor permeability of PU thin membranes were studied.

In order to reasonably and efficiently develop and utilize almond gels,the law for the changes of texture properties in different mass fractions of almond gels was studied by using TA-XT2i texture analyzer.

Proceeding from the concepts and definitions of the activities of components in metallurgical melts and their standard states, the discrepancies about applying the mass fraction and mass percent concentration to metallurgy were analyzed and discussed.

Research on fluorine concentration in coals from Guizhou province by pyrohydrolytic-ion chromatograpy;

Experiment and numerical simulation on chloride concentration cumulating in concrete affected by reinforcement

Using compressed air foam system and drainage apparatus,the drainage process of compressed air foam with typical protein based class A agent was studied under the concentration range of 0.

So,the method for testing the content of wax in jadeite jade is quite important.

During the process of precious metal content tested by using the X-ray fluorescence spectrometry,the measurement system is based on the standard curve and the results are given directly by the equipment,which could be equivalent to the direct measurement.
