On the differences in determining the time and vertical velocity characteristic scales and analyzing high order derivatives suggested by certain authors, discussions are made and preliminary conclusions are drawn, namely,τ~L/U, W≤ MUH/L and  nf/x n～F/L n,n>1 for a single scale motion.

A preliminary discussion of correction method in the calculation of atmospheric vertical velocity;

Creation mechanism of take-off vertical velocity of long jump on kinematics and kinetics;

Biomechanical research of the vertical velocity of high jump take-off;

The nature of the jumping action is to create the vertical speed while the horizontal speed has been obtained from approach running.

The analysis shows that the long-jump run-up take-off training should put increasing the horizontal speed as well as vertical speed on the first place in physical education.

The characteristic scales of the urban landscape in the Nanjing metropolitan region;

A study on characteristic scale of reservoir rock continuity;

The natural lacunarity curve was firstly employed in the Hetian Oasis landscape pattern and the zigzag oasis sample for their spatial heterogeneity in multi-scales,and then the coherence and complementary validation was performed on the characteristic scale extraction of the Hetian Oasis by landscape lacunarity analysis and wavelet transformation.
