Abstract
Novel dynamic formula atmospheric pressure there is the basic structure of demonstrator and technical characteristic is: hold up the long straight transparent pipe of one section of both ends open, a colored slip stopper is filled in the lower end of transparent pipe, and the lower end of transparent pipe is sealed, in transparent pipe, fill water again, and the upper end of transparent pipe is also sealed.
Description
Technical field: the invention provides a kind of junior physics experimental apparatus, especially relates to a kind of Novel dynamic formula atmospheric pressure and there is demonstrator.
Technical background: existing various being used in junior physics laboratory demonstrates atmospheric instrument, and have simple to operate, the operation also had is more loaded down with trivial details, generally speaking, uses these demonstration instruments not to be very enough to demonstrate its innervation of atmospheric existence.The present invention is exactly that a kind of novel dynamic formula atmospheric pressure designed exists demonstrator in order to improve the innervation demonstrating atmospheric pressure existence.
Technical scheme: the purpose of design that there is demonstrator in order to realize this Novel dynamic formula atmospheric pressure, basic structure of the present invention and technical characteristic are: hold up the long straight transparent pipe of one section of both ends open, a colored slip stopper is filled in the lower end of transparent pipe, and the lower end of transparent pipe is sealed, in transparent pipe, fill water again, and the upper end of transparent pipe is also sealed.Specific embodiments 1 is: the glass or the long straight transparent pipe of resin formula that comprise a both ends open, helixseal cap, tank, section cascaded fixed mount, bore is slightly smaller than the sliding stopper of light color of bore in transparent pipe, bore is a bit larger tham the concave water shutoff cap of the outer bore of transparent pipe, there is the parts compositions such as the beaker of feeding the mouth of a river, concrete technical scheme is: first long straight transparent pipe is mounted on section cascaded fixed mount fixing, and tank is placed in below long straight transparent pipe, again sliding for light color stopper is filled in lower end in transparent pipe, and screw in helixseal cap transparent pipe lower end is sealed, then whole transparent pipe is filled by having the beaker Dig water of feeding the mouth of a river, and be inserted in concave water shutoff cap on transparent pipe top can be stand-by, specific embodiments 2 is: comprise the glass of a both ends open or the long straight transparent pipe of resin formula, the sliding stopper of light color that helixseal cap, bore are slightly smaller than bore in transparent pipe, bore be a bit larger tham the parts compositions such as the concave water shutoff cap of the outer bore of transparent pipe, concrete technical scheme is: comprise the glass of a both ends open or the long straight transparent pipe of resin formula, the sliding stopper of light color that helixseal cap, bore are slightly smaller than bore in transparent pipe, bore be a bit larger tham the parts compositions such as the concave water shutoff cap of the outer bore of transparent pipe.First sliding for light color stopper is filled in lower end in transparent pipe, and screws in helixseal cap transparent pipe lower end is sealed, then in whole transparent pipe, fill water, and be inserted in concave water shutoff cap on transparent pipe top can be stand-by; Here it is there are two kinds of embodiments of demonstrator in novel dynamic formula atmospheric pressure.
Principle of work: the principle of work that this novel dynamic formula atmospheric pressure exists demonstrator embodiment 1 is: first the novel dynamic formula atmospheric pressure assembled is existed demonstrator during use and be placed in horizontal table top, then outward winding and grow the helixseal cap of straight transparent pipe lower end, student can see that the colored slip stopper being positioned at long straight transparent pipe lower end automatically gently rises along long straight transparent pipe inside, and the water in long straight transparent pipe oozes out from colored slip stopper surrounding slowly, and along growing the inwall of straight transparent pipe slowly toward dirty, until colored slip stopper rises to the inner top of long straight transparent pipe.Wherein long straight transparent pipe top is inserted in is concave water shutoff cap for this, object utilizes the female parts of water shutoff cap to extrude the water filled in transparent pipe, ensure that whole transparent pipe is inner and be not definitely mixed into air except water, thus ensure that atmospheric pressure can overcome the jointly downward pressure of water column in colored slip stopper and whole transparent pipe, promote colored slip stopper and slowly rise along the inwall of long straight transparent pipe; The principle of work of embodiment 2 is substantially identical with the principle of work of embodiment 1.
Social benefit: this novel dynamic formula atmospheric pressure exists demonstrator owing to employing dynamic demonstration mode, therefore, it is possible to excite Students ' Learning better and probe into atmospheric interest, and simple structure, compact conformation, install simple, easy to use, total manufacture or use cost are not high yet, once promoting the use of, to promoting that the development of junior middle school physics teaching and junior middle school physics teaching instrument has important practical significance.
