Abstract
An experimental instrument for measuring liquid surface tension coefficient by adopting the half-bubble method relates to the technical field of physical experiments or detection. The experimental instrument comprises a measurement box (1), a digital display micro air gauge (2) and an inflating bag (3), wherein the measurement box (1) is a box body with at least one surface box wall adopting an openable structure; a plane mirror structure is arranged on the inner side of one side box wall of the measurement box (1); the side box wall opposite to the plane mirror is a transparent body with vertical scales; and a foaming hole (4) is formed at the bottom of the measurement box (1) and simultaneously communicated with the digital display micro air gauge (2) and the inflating bag (3) through a pipeline. The experimental instrument has the advantages of simple structure, definite principle, simplicity and convenience in operation, easiness in bubble formation, apparent phenomena, and two functions of demonstration and quantitative inspection, and can achieve the continuous variation characteristic of radii of bubbles so as to show the relationship between the bubble radii and the surface tensions under the condition of the same precision, thereby facilitating applying various data processing manners.
Description
Technical field
The utility model relates to Physical Experiment or detection technique field, is specifically related to a kind of half bubble method and surveys the Coefficient of Tension of Liquid Surface appearance.
Background technology
The most frequently used experimental technique has the breakaway connector direct method of measurement, the kapillary rising formula indirect method of measurement and the maximum bubble method etc. of dripping in Physical Experiment.The breakaway connector experimental method is simple to operate and directly perceived, influences big, the easy generation than mistake but influenced with instrument performance by operator's human factor; Capillary tube technique is comparatively accurate, but bore and intraluminal fluid post height are difficult to accurate measurement.
Summary of the invention
The utility model technical matters to be solved is: provide a kind of half bubble method that can accurately measure to survey the Coefficient of Tension of Liquid Surface appearance.
The technical solution of the utility model is: it comprises measure case, digital display microbarometer and the capsule of inflating; Measure case is that to have a tank wall at least be the casing of retractable structure; Measure case one of which side box wall is provided with the level crossing structure in the inboard; A side box wall relative with level crossing is the transparent body that is provided with vertical scale, and the bottom of measure case has foam hole, and foam hole is communicated with the digital display microbarometer and the capsule of inflating through pipeline simultaneously.
The technique effect of the utility model is: it has simple in structure; Clear principle, easy and simple to handle, bubble forms easily; Phenomenon obviously, have demonstration and two kinds of functions of quantitative measurment; Owing to can realize bubble radius continually varying characteristics, thereby appearing of concerning between the vacuole radius and surface tension under the precision conditions such as be implemented in, make things convenient for the utilization of several data processing mode.
Description of drawings
Fig. 1 is the three-dimensional structure diagram of the utility model.
Embodiment
As shown in Figure 1; It comprises measure case 1, digital display microbarometer 2 and the capsule 3 of inflating; Measure case 1 is the casing of retractable structure for having a tank wall at least, and measure case 1 one of which side box wall is provided with the level crossing structure in the inboard, and a side box wall relative with level crossing is the transparent body that is provided with vertical scale; The bottom of measure case 1 has foam hole 4, and foam hole 4 is communicated with the digital display microbarometer 2 and the capsule 3 of inflating through pipeline simultaneously.
Said measure case 1 has at least a tank wall to be provided with the hole with external communications except that the bottom surface.
Embodiment one:
Utilize water white poly (methyl methacrylate) plate to process foam box, open a foaming aperture at base plate, top cover is with holes; Communicate with the external world guaranteeing, one is sidelong to have and can opens glass door, can be conveniently in foam hole injection testing liquid and on base plate, brush testing liquid; In order to guarantee the smooth formation of half bubble, print or stickup rectangular coordinate pattern at plate outer surface, with the diameter of convenient directly observation bubble; At front side board the vernier caliper that can move up and down is installed, at the inside surface mounting plane mirror of back side panel, in order to the radius of accurate measurement bubble; In base levelling bolt is installed; And spirit-leveling instrument is installed on base plate, in order to guarantee floor level, be furnished with the capsule of inflating of digital microbarometer and band self-locking device in addition; And microbarometer, the capsule of inflating are connected with foam hole with sebific duct with three-way pipe, to ensure the accurate mensuration of foaming minute-pressure difference smoothly and inside and outside the bubble.
When carrying out qualitative demonstration research, can obviously observe the Changing Pattern that bubble diameter appears with the variation of air pressure inside; When carrying out quantitative measurment, can be through the measured many groups experimental data of same change procedure, the graphic interpretation of applying in a flexible way, carry out data processing by difference method, averaging method and least square method etc.
