Establishment a concept of "quantity" in the quantitative analysis experiment;

Comparable of Schools of Quantity Theory of Ancient Indian;

According to national standards of quantities and units,the quantities discribing compositions of mixtures were introduced,and the usage of contents was probed into.

This paper analyzes several common problems existing in the use of the quantities and units in geologic journal with examples, and points out that implementing the national standard of the quantities and units by geologic journal is beneficial to not only the domestic and foreign academic exchange but also to Chinese sci-tech periodicals’ going to the world.

Considering the confusion of usage on the comp osition scales of mixtures and solutions in chemistry and biology at present, in order to promote popularization and application of the national standards for quantities and units, it was introduced the usage on the composition scales of mixtures and solutions in chemistry and biology in accordance with the national standards.

With the high-speed development of national economy, the domestic petroleum resource can't meet the need of the internal market; therefore the amount of imported petroleum is rising.

To experiment inthe theoretical amounts of the original teaching material,it will not only expend large amounts of reageut,bu-talso be unobtrusive, ncoreover, no result to appear.
