But, the bead of preceding case, remove traditional abacus unique spacer and represent quantity " fives' " bead, be to be a string with nine beads, though color separation in the sixth of the twelve Earthly Branches on the basis of using, every limit pearl string is long, the in fact study of unfavorable iconic memory, and numeral " eight " and " seven " are taken place easily, " four " see the facts of obscuring with " three " mistake.

Because above-mentioned commonly use abacus and before the existing shortcoming of case, the utility model people is at the deep research and design in addition of above-mentioned disappearance, after experiment improves in many ways, generation of the present utility model is arranged finally.

Summary of the invention

Fundamental purpose of the present utility model, i.e. the new-type abacus design of easier interpretation when a kind of the calculation is provided makes things convenient for image study, iconic memory to reach, and then increases learning efficiency and entertaining.

The architecture advances of a kind of decimal system abacus of the utility model, it respectively is provided with the figure notation of " 5 " on the edge of the left and right sides of a framework, logarithm purpose memory when calculating to increase, and in framework, be provided with several axostylus axostyles, string has nine beads on the every axostylus axostyle, every bead is represented numeral " ", and five is one group above the bead, below four be one group, two groups altogether, two groups of bead colors are different, and for example one, two, three, four, five is yellow, six, seven, eight, nine is red, in view of the above, make when operation calculation with the decimal system, can be by the permutation and combination of two kinds of colors being convenient to distinguish, correct interpretation goes out numeral fast.

For further understanding composition of the present utility model, mode of operation, reach the effect that is produced, lift the utility model now than specific embodiment, and be described with reference to the accompanying drawings as follows:

Embodiment

Consult Fig. 1, shown in Figure 2, the utility model respectively is provided with 1 on the left and right sides edge of a

framework

1,2,3,4,5,6,7,8,9 figure notation " 5 ", logarithm purpose memory when calculating to increase, and in framework 1, establish the axostylus axostyle 2 that several parallel longitudinals are arranged, string has nine beads 3 on the every axostylus axostyle 2, its improvement is characterised in that: every adjacent top five beads 3 are one group, below four be first group, below four be first group, two groups separate mutually with different colors, except that the difference that can utilize bead 3 positions, more can utilize the color interpretation to go out numeral, quick and convenient.

During enforcement, two groups color can arbitrarily be matched, for example, wherein one, two, three, four, five is yellow, six, seven, eight, nine is red, and the upper ledge lower frame of first, fourth, seven, ten, 13 rows' axostylus axostyles 2 and its framework 1 intersection on skeleton frame respectively is provided with a gauge point 4, as the usefulness of differentiating a position, kilobit, megabit, billibit, megabit.
