Abstract
The invention discloses a novel dynamic atmosphere pressure existence demonstration instrument. The novel dynamic atmosphere pressure existence demonstration instrument structurally and technically characterized in that a segment of long and straight transparent tube of which openings are arranged at two ends is vertically arranged; a colorful sliding plug is inserted into the lower end of the transparent tube; the lower end of the transparent tube is sealed; the transparent tube is full of water; and the upper end of the transparent tube is also sealed.
Description
Technical field: the invention provides a kind of junior physics experimental apparatus, especially relate to a kind of novel dynamic formula atmospheric pressure and have demonstrator.
Technical background: the existing various atmospheric instruments that are used for demonstrating in junior physics laboratory, have simple to operately, the operation that also has is more loaded down with trivial details, and generally speaking, it is not very enough using these demonstration instruments to demonstrate its innervation of atmospheric existence.The present invention is exactly that a kind of novel dynamic formula atmospheric pressure that designs for the innervation that improves the existence of demonstration atmospheric pressure exists demonstrator.
Technical scheme: have the purpose of design of demonstrator in order to realize this novel dynamic formula atmospheric pressure, basic structure of the present invention and technical characterictic are: hold up the long straight transparent pipe of one section both ends open, a colored slip stopper is filled in the lower end of transparent pipe, and the lower end of transparent pipe sealed, in transparent pipe, fill with 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, the helixseal cap, tank, lasso formula fixed mount, bore is slightly smaller than the sliding stopper of light color of bore in the transparent pipe, bore is a bit larger tham the indent formula water shutoff cap of the outer bore of transparent pipe, having the parts such as beaker of feeding the mouth of a river forms, concrete technical scheme is: at first be placed on long straight transparent pipe box on the lasso formula fixed mount fixing, and tank placed long straight transparent pipe below, again the sliding stopper of light color is filled in lower end in the transparent pipe, and screw-in helixseal cap seals transparent pipe lower end, fill with whole transparent pipe by having the beaker Dig water of feeding the mouth of a river then, and be inserted in indent formula water shutoff cap on transparent pipe top can be stand-by; Specific embodiments 2 is: comprise that the long straight transparent pipe of the glass of a both ends open or resin formula, helixseal cap, bore are slightly smaller than the parts such as indent formula water shutoff cap that the sliding stopper of light color of bore in the transparent pipe, bore be a bit larger tham the outer bore of transparent pipe and form, concrete technical scheme is: comprise that the glass of a both ends open or the long straight transparent pipe of resin formula, helixseal cap, bore are slightly smaller than the sliding stopper of light color of bore in the transparent pipe, the parts such as indent formula water shutoff cap that bore is a bit larger tham the outer bore of transparent pipe are formed.At first the sliding stopper of light color is filled in lower end in the transparent pipe, and screws in the helixseal cap transparent pipe lower end is sealed, in whole transparent pipe, fill with water then, and be inserted in indent formula water shutoff cap on transparent pipe top can be stand-by; Here it is, and there are two kinds of embodiments of demonstrator in novel dynamic formula atmospheric pressure.
Principle of work: this novel dynamic formula atmospheric pressure exists the principle of work of demonstrator embodiment 1 to be: exist the novel dynamic formula atmospheric pressure that assembles demonstrator to be placed on the horizontal table top earlier during use, the helixseal cap of the straight transparent pipe of the length of outwarding winding then lower end, the student can see that the colored slip stopper that is positioned at long straight transparent pipe lower end automatically gently rises along long straight transparent pipe inside, and around the colored slip stopper, the oozing out slowly of the water in the long straight transparent pipe, and along slowly past dirty of the inwall of long straight transparent pipe, rise to till the inner top of growing straight transparent pipe up to the colored slip stopper.Wherein long straight transparent pipe top is inserted in is indent formula water shutoff cap for this, purpose is to utilize the female parts of water shutoff cap to push the water of having filled with in the transparent pipe, guarantee that whole transparent pipe inside does not definitely have entrained air except water, thereby guarantee that atmospheric pressure can overcome the common downward pressure of water column in colored slip stopper and the whole transparent pipe, promotion colored slip stopper slowly rises along the inwall of long straight transparent pipe; The principle of work of the principle of work of embodiment 2 and embodiment 1 is basic identical.
Social benefit: there is demonstrator in this novel dynamic formula atmospheric pressure owing to used dynamic demonstration mode, therefore can excite the student to learn better and probe into atmospheric interest, and simple structure, compact conformation, install simple, easy to use, total manufacturing or use cost are not high yet, once promoting the use of, the development that promotes junior middle school physics teaching and junior middle school physics teaching instrument are had important practical significance.
