Abstract

The invention discloses a measuring method for density physical parameter of solid material or other solid specimen, especially the measuring method for physical parameter of solid material specimen with any shape and density less than 1g / cm3. Based on the function of density measuring device for solid substance, weight P1 of measured specimen is measured in air by the density measuring device for solid substance. A standard substance with known weight and cubage is added on the measured specimen and they are immerged into liquid or water completely. P2 is measured by the density measuring device for solid substance. By formula (3) the density of specimen with irregular shape and density smaller than 1g / cm3 can be obtained. The density measuring method for specimen with irregular shape and density smaller than 1g / cm3 can be solved and density measurement for specimen with density smaller than 1g / cm3 can be realized. Analysis for geophysical exploration and building material or measuring class of specimen can be added.

Description

Field of invention:

[0001] The invention relates to a method for measuring density physical parameters of solid materials or other solid specimens, especially a method for measuring density physical parameters of solid materials with arbitrary shapes. Background technique:

[0002] Density is a physical parameter of matter that is used in many fields. There are many methods for measuring the density of solid specimens. Such as the use of radioactive principle measurement method, unequal arm balance method, microwave technology measurement method and indirect measurement method using Archimedes' law. These measurement methods all have the disadvantages of low measurement accuracy, manual recording, and relatively slow measurement speed. CN2051738U discloses " rock (ore) rock density measuring instrument " has improved test efficiency and precision than previous density test method, but because of being limited by sensor, there is also the same load cell used for larger or s...
