Three bearing point of the 3-DOF Parallel Driven Platform adopted the distribution of the right triangle, and calculation and comparison with the other three bearing point of parallel driven platform show that the platform only produces a additional movement of rotating z_axis, and the structure is simple, and easy to r.

According to the research of the sides and the integer in a right triangle, this thesis puts forward the subject on the numbers of triangles on condition that the hypotenuse is the odd prime number and the right-angle side is the integer, and then makes a demonstration for it by means of the formula 2n+1=p, and number sequence.

This paper proves that the triangle method and the uncertain degree weight method for transforming vague sets into fuzzy sets are practical methods,and proves that these methods are the same methods,and proves that these methods are the special cases of the weight mean modified methods.

Method of isosceles right triangle on Fuzzy clustering;

In order to improve the ratio of binary image compression,using top-dowm method of coding,bring forward a fractal image compression method based on isosceles right triangle,and simulated.
