Abstract
The invention provides a method used for measuring the volume of article with complex shape without water immersion, comprising the steps as follows: a barometer is arranged in a sealed container; furthermore, current air pressure value is read out; subsequently, the article is arranged in the container; a measurable air pump is used to pump air in the container; and when the air pressure in the sealed container is equal to two times of the air pressure value, the value gained by subtracting the volume of the pumped air from the volume of the container is the volume of the article. The method can measure the volume of articles of various complex shapes; the article needs no contact with water; therefore, the method can be used for the volume measurement of wood products, paper products and cultural relics such as ceramics, painting and calligraphy and the like, and has the advantages of exact measurement and simple operation.
Description
Technical field
The present invention relates to measuring technique, particularly about the measuring method of object volume.
Background technology
Accurately measure the volume of irregular-shaped objects, generally adopt bowssening, object is immersed be equipped with in the measuring cup of water exactly, the reading of observed quantity water in the cup face changes, and this changing value is exactly the bulking value of object.But because a lot of objects can not be immersed in the water, such as woodwork, paper products, also have pottery historical relic etc., in order to understand their material, need to measure its proportion usually, this just must measurement volumes, does not also have the method for this type objects volume of non-immersiom measuring at present.
Summary of the invention
The object of the invention is to provide a kind of method of non-immersiom measuring object volume with complicated shape, uses with convenient.
The solution of the present invention is: the method for non-immersiom measuring object volume with complicated shape, it is characterized in that: with an airtight container, place barometer inside, and read at that time atmospheric pressure value, again object is placed this container, in container, be pressed into air, when waiting air pressure in the closed container to equal the twice of above-mentioned atmospheric pressure value with gageable air pump, volume with container deducts the volume that is pressed into air, and this numerical value is exactly the volume size of object.
Advantage of the present invention is: because container is airtight, pack into behind the object, the surplus air volume of the inside is exactly the volume that the volume of container deducts object, when air pressure reaches twice, illustrate that the volume that is pressed into air equals the volume of original surplus air, so just known the volume size of original surplus air, the volume of container deducts the volume of original surplus air, and this numerical value is exactly the volume size of object.This method can be measured the volume of various complicated shape objects, and object does not need to touch water, can be used for woodwork, paper products, the cubing of historical relics such as pottery, painting and calligraphy in addition.Have and measure advantage accurate, simple to operate.
Description of drawings
The invention will be further described in conjunction with the accompanying drawings according to embodiment below.
Accompanying drawing is the structural representation of equipment therefor of the present invention.
1 container among the figure, 2 kaysers, 3 gland bonnets, 4 gas pipings, 5 gageable air pumps, 6 barometers, 7 objects.
Embodiment
The measurement of embodiment with the structure of device is: container 1 is a cylindrical glass jar, and bead is equipped with rubber weather strip, is stamped a gland bonnet 3 above the container 1, and gland bonnet 3 usefulness kaysers 2 are pressed on and realize sealing on the container 1.
One air hole is arranged on the gland bonnet 3, be connected with gageable air pump 5 with gas piping 4, gageable air pump 5 adopts an inflator that has scale, and it can know the amount of inflating by the scale on the piston rod.
Placed one in order to measure atmospheric barometer 6 in container 1 the inside.
Measuring process first:
1. first water is filled container, measures its volume, and is standby after water is outwelled, dried.
2. object 7 is put into container 1, build gland bonnet 3, compress with kayser 2.
3. write down the air pressure of this moment.
4. begin in container 1, to inflate, be shown to the twice of step 2 record value, the amount that record is inflated until barometer with gageable air pump 5.
5. the volume of container deducts the amount of inflating, and this numerical value is exactly the volume size of object.
After having known the volume of container, measure just without repeating step 1, directly from step 2 next time.
Measuring process is carried out under the constant temperature situation, in order to avoid air changes owing to expanding with heat and contract with cold.
Claims (1)
- The method of non-immersiom measuring object volume with complicated shape, it is characterized in that: with an airtight container, place barometer inside, and read at that time atmospheric pressure value, again object is placed this container, in container, be pressed into air, when waiting air pressure in the closed container to equal the twice of above-mentioned atmospheric pressure value with gageable air pump, volume with container deducts the volume that is pressed into air, and this numerical value is exactly the volume size of object.
