Secondly,the pointwise recurrent Warsaw circle maps are the identity map and that h_A(fg)=h_A(gf) for each increasing sequences of positive integers A.

It is showed that if f is pointwise chain recurrent (that is, every point of X is chain recurrent under f),then f is identity if Fix(f) is connected;f is turbulent if Fix(f) is disconnected.

Through stepwise regression analysis of the damaging degree and the willow features,the relationship between the variant regulation of the indices among different willow varieties and damage degree by Anoplophora glabripennis were studied.

In terms of artificial neural network method,mean generation function and stepwise regression analysis,a prediction model for the annual number of tropical cyclones affecting Guangxi is developed in this paper.

The test data are analyzed with progressive regression,finding that the load-bearing capacity of package of T203 and T204 is superior to T202 but their anti-oxidation and anti-corrosion abilities are well-matched,and DNA and CuDDP have good anti-oxidation performances.

Firstly,progressive regression technique is used to seek the dominating factors affecting energy forecast and eliminate the secondary ones.
