A kind of loose-leaf system laboratory report

One, technical field:

The utility model relates to the teaching of generally using in university's teaching Process of experiment and use this, what be specifically related to is a kind of loose-leaf system laboratory report.

Two, background technology:

In the course that university was offered between the learning period, some course contains experimental project.The teacher need organize the student and do experiment, and after laboratory finished, the teacher also need mark, estimate student's experiment situation, and needs of students is used the related content of laboratory report record experiment etc. for this reason.Laboratory report like School of Economics and Business Management of Heilongjiang Bayi Agricultural Reclamation University is made up of strip of paper used for sealing and this core, and this core is bound between upper and lower strip of paper used for sealing; Be printed on printed words such as " laboratory report ", " course name ", " specialty ", " instructor " on the strip of paper used for sealing, be used to show the service orientation of laboratory report; This core is formed by the paper set of 10 unified sizes; The record format of every page of this core is all identical; Every page front all is made up of title bar and content bar; Title bar is printed on the printed words of " laboratory report " on top, content bar is divided into " experiment title ", " experiment purpose ", " experiment material instrument and equipment ", " experiment content and requirement ", " experimentation step " five columns; The reverse side of every page of this core is content bar, and this reverse side comprises " experimental result and analysis ", " experiment is known from experience ", " experiment achievement ".Wherein, in " experimental result and analysis " column content written generally all be by the student according to the postrun result of computer software, add the analysis of oneself after, copy in the blank space of " experimental result and analysis " column with straight.But for more, the more loaded down with trivial details experimental project of data result (or figure), it is more not only to cause the student to repeat work, and writes the space and can not guarantee.

Now, the student accomplishes experiment related content record through buying above-mentioned whole laboratory report, but because the part course only has 3-5 experimental project, this core of 5-7 page or leaf residue will be arranged approximately like this.Because number of student is more, will cause a large amount of wastes of this core like this.Simultaneously, because every part of laboratory report all has strip of paper used for sealing up and down, not only waste paper, increase purchase cost, and greatly increased the volume of laboratory report, institute has nothing for it but and stores laboratory report more space is provided.

Three, summary of the invention:

The purpose of the utility model provides a kind of loose-leaf system laboratory report, and " experimental result and analysis " column that this loose-leaf system laboratory report is used to solve present laboratory report writes that the space is not enough, attached sheet are lost easily and nonstandard problem and the unnecessary waste problem that this core and strip of paper used for sealing caused.

The utility model solves the technical scheme that its technical problem adopted: this loose-leaf system laboratory report by folding hard front cover, split clamp ring mechanism and this core is formed; Split clamp ring mechanism and be fixed on the hard front cover middle part, this core is contained in the clamp ring of splitting and between last strip of paper used for sealing and following strip of paper used for sealing; The reverse side of every page of this core all is provided with the material bag of placing the attached sheet material.

Material bag sticks on the reverse side of every page of this core in the such scheme, and material bag both sides and bottom stick on the reverse side of every page of this core, and the upper end is a sack, is used to put into or takes out experiment attached sheet material.

Beneficial effect:

1, this core in the utility model all is unified laboratory report lists that the loose-leaf hole is arranged of printing, and can split clamp ring and takes out easily or add through opening, and need not to tear.During use, earlier be distributed to the student according to the quantity of needs of students, after the student accomplishes and writes, deposit in the loose-leaf binder after collecting the loose-leaf report by the teacher by the teacher, convenient management not only, and can practice thrift a large amount of paper and the space that stores laboratory report.For example, be example with the microeconomics, this subject has 3 experimental projects, calculates by one 50 people's class, and loose-leaf system laboratory report and current experiments report unusable paper quantity contrast as follows:

The loose-leaf system laboratory report uses this core quantity=experimental project number * number of student=3 * 50=150 to open

The loose-leaf system laboratory report uses strip of paper used for sealing quantity=go up strip of paper used for sealing+following strip of paper used for sealing=2

Loose-leaf system laboratory report unusable paper Volume Composition=this core quantity+strip of paper used for sealing quantity=152

Existing laboratory report uses this core quantity=whole this core of this report quantity * number of student=10 * 50=500 to open

Existing laboratory report uses strip of paper used for sealing, and quantity=strip of paper used for sealing quantity * number of student=2 * 50=100 opens up and down

Existing laboratory report unusable paper Volume Composition=this core quantity+strip of paper used for sealing quantity=600

It is thus clear that the required paper of microeconomics curriculum experiment that uses two kinds of laboratory reports to accomplish a class just differs nearly 450.And the class that school offers the microeconomics course every year is all about 10-15 class, and only this subject just can be practiced thrift a large amount of paper.Every for course less than 10 experimental projects, all can calculate the number of paper that can practice thrift by this kind method; Even have the course of 10 experimental projects, also can practice thrift 2 times of class sizes' strip of paper used for sealing, and strip of paper used for sealing uses all generally the higher color page of the better price of quality to print, can be the student like this and practice thrift the cost of buying laboratory report.

Because the loose-leaf binder of general requirements all can be deposited the paper more than 500 pages; Many persons can deposit more than 800 pages; So can also several classes be left in same the loose-leaf binder with the laboratory report of a branch of instruction in school; It is just passable only to need to indicate title and the course name of depositing class in homepage, will practice thrift the storage area of laboratory report so more.
