Pure substances are known to have constant or fixed properties, while mixtures have varying physical and chemical properties. Despite the clear difference between pure substances and mixtures, there is still a gray area. Mixtures are either homogeneous or heterogeneous. Homogeneous mixtures are often co...
15. Its rationality lies in reasoning and its objectivity lies in pure observal facts. 它的合理性在于它是逻辑论证的结果,它的客观性在于经验事实的纯粹性。 16. 16. Graphite: It is made of the high pure and super fine graphite which is treated specially. ...
Finally, a non-estrogenic compound (100 μM Digitonin) produced an RTA of less than 0 %, demonstrating the precision of the assay in distinguishing between estrogenic, anti-estrogenic and neutral substances. These quality control steps ensure reliable results for further analysis. In the case...

enzymes. These nonspecific-factor absorbing substances are then carried by ultramicrospheres by usual methods, namely, by causing them to bear such absorbing substances either singly or as mixtures by physical adsorption or chemical covalent bonding. Although no particular limitation is imposed on the ...
The process specified by this invention, whereby fluorspar is exposed to a reaction with a mixture consisting of sulphuric acid, oleum and the reflux of the acidic scrubbing substances, is characterized in that the acidic mixture, to be fed into a three-stage reactor, is first preheated to a...
