Problems solved by technology

[0003] The existing measurement method must first place the measured solid in the air for gravity measurement, and then place the measured solid in the liquid for measurement. The measurement of the two steps needs to be carried out manually, and they are carried out in different places. Measurement in the environment affects the speed and efficiency of measurement

Embodiment 1

[0011] Embodiment 1: The measured solid 6 is an industrial steel sample in this embodiment, and the standard density is 7.85g / m 3 . First add in liquid container 4 =1g / cm3 of water, then record the readings of the two scales at this time =1230.37g, =23.651g; then place the measured solid 6 on the end of the support 3 that penetrates into the liquid container 4, ensure that the measured solid 6 is completely submerged in the water contained in the liquid container 4, and record the readings of the two gravimetric measuring devices at this time again =1240.37g, =32.383g; Finally, substitute the two recorded gravity readings into the solid density calculation formula , thus calculating =7.886g / m 3 , that is, the density of the measured solid 6 .

Embodiment 2

[0012] Embodiment two: in the present embodiment, measured solid 6 is lead block sample, and standard density is 11.34g / m 3 . First add in liquid container 4 =1g / cm3 of water (can be water, or replaced with other liquids with known density), and then record the readings of the two gravity measuring devices at this time =1230.14g, =23.651g; then place the measured solid 6 on the end of the support 3 that penetrates into the liquid container 4, ensure that the measured solid 6 is completely submerged in the water contained in the liquid container 4, and record the readings of the two gravimetric measuring devices at this time again =1242.44g, =34.864g; Finally, substitute the two recorded gravity readings into the solid density calculation formula

[0013] , thus calculating =11.316g / m 3 , that is, the density of the measured solid 6 .

Embodiment 3

[0014] Embodiment three: in this embodiment, the measured solid 6 is red copper, and the standard density is 8.9g / m 3 . First add in liquid container 4 =1g / cm3 of water, then record the readings of the two gravity measuring devices at this time =1242.46g, =23.650g; then place the measured solid 6 on the end of the bracket 3 that penetrates into the liquid container 4, ensure that the measured solid 6 is completely submerged in the water contained in the liquid container 4, and record the readings of the two gravimetric measuring devices at this time again =1251.88g, =32.010g; Finally, substitute the two recorded gravity readings into the solid density calculation formula , thus calculating =8.887g / m 3 , that is, the density of the measured solid 6 .

[0015] In the above embodiment, for the convenience of measurement, the gravity measuring device can be replaced by a scale, and the effect is the same. Limited by the experimental conditions, the measurement error...

Abstract

The invention relates to the field of measuring the density of a solid, specifically to a method for measuring the density of a solid and a measuring device of the method. The measuring device comprises a big gravity measuring device and a small gravity measuring device, a support, and a liquid container. The method comprises the following steps: (1) firstly, pouring a liquid with the known density into the liquid container, marking the density as rho liquid, and recording readings of the two gravity measuring devices at present as G large and G small; (2) then, putting the to-be-measured solid at one end, deep in the container, of the support, and recording readings of the two gravity measuring devices at present as G large1 and G small1; and (3) finally, substituting the recorded data into a formula of rho solid=(G large1-G large)*rho liquid / [(G large1-G large)-(G small1-G small)] to calculate the density, rho solid, of the solid. The measuring device is simple in structure, and the method is accurate in measurement, and high in measurement speed and measurement efficiency.

Description

technical field [0001] The invention relates to a measuring method, in particular to a solid density measuring method and a measuring device thereof. Background technique [0002] At present, the existing solid density measurement method is basically based on the solid density measurement device based on the Archimedes principle. This solid density measurement method requires two manual steps in the whole measurement process: the first step, in the Measure the gravity G1 of the measured solid in the air; in the second step, put the measured solid into the liquid and measure the density of the solid at The weight G2 in the (liquid with known density) liquid; finally by calculating the formula To calculate the solid density . [0003] The existing measurement method must first place the measured solid in the air for gravity measurement, and then place the measured solid in the liquid for measurement. The measurement of the two steps needs to be carried out manually, and ...
