- Besides, the valent state of Mo, the surface pattern and distribution of Mo on this catalyst, and the formation of catalytic active matter and so on were studied preliminarily.
- This paper studies the fertilization of gangue weathering matter centered around its serious deficiencies in organic active matter and available nutrients.
- The conditions for process control of slug concentration and content of powder active matter were improved.The first-stage acceptability rate of powder detergent was upturned.
- Polarimeter, which is known as an optical rotation meter, is an instrument to measure optical rotation of "optically active matter" such as saccharin, ascorbic acid and sodium glutamate.
- Most STR has no function of coding, maybe they have activating matter, recombination site and the function of combining site of DNA topoisomerase.
- The Method used to separate anti-tumor activity matter from bark of Ailanthus altissima Swingle was studied in this paper.
