Based on people-oriented principle, this design utilized Chinese 'Fu' (blessings) culture to express people’s eager for a better life and the atmosphere of good fortune. It also produced the image of ecological environment by designing water landscapes and plant landscapes, created active space like squares for activity and active water system and developed the characteristics of residential districts by designing landscape sketches and plant landscapes.展开更多

As a parameter is smoothly increased, a fascinating variety of dynamic behaviors are produced. For some families the behaviors are monotonic in the parameter, while in others they are not [3]. The question is what sort of conditions on a one parameter family will ensure this monotonicity of the behavior with the parameter？ The answer is unknown and will not be given here. What we do instead is to investigate certain geometric-dynamic-combinatorial consequences of assuming that the family has this monotonicity. Specifically, using tools of symbolic dynamics, state space is ＂course grained＂ with a finite alphabet. We decompose a non-invertible map into nonlinear but invertible pieces. From these invertible pieces, we form inverse maps via composition along words. Equations of motion are developed for both forward and inverse orbits （in both the variables of state space and the parameter）, and an equation relating forward and inverse motions at fix-points is exhibited. Finally, we deduce a list of conditions, each of which is equivalent to monotone behavior. One of these conditions states that simple parity characteristics of words correspond to definite dynamics near fixed-points and vice versa.展开更多

The mitochondrial genome （mtDNA） polymorphism is directly related to motor activity and has a high maternal genetic trait. Athlete mothers have higher testosterone, and their children have athletic advantages. 2D： 4D and mtDNA have good genetic markers, which are of great significance and prospect for the study of their inheritance of motor ability.展开更多
