Analysis of elderly people s discrimination capability on bumpy roads;

The concave-convex property of a surface is one of the important and classical issues in differential geometry.

This article present the continuity,differentiability,monotonicity,concave-convex,parity and periodicity of the function netermined by the definite integral of variable upper limit and variable lower limit,establishes the sufficient and necessary requirements of functional convex and integrability of derived function by using the definite integral of variable upper limit.

Some definitions and discriminating methods have been given on the monotonicity,extreme value,concave-convex and inflection points of the curve r=r(θ).
