Three pulsars (PSR 0329+54,0834+06,1133+16) with high quality signal-to-noise of radio mean pulse profiles are selected from the available literature.The characteristics of the radio mean pulse profiles are analyzed for three pulsars.The phase-resolved spectrum and the correlations between radio emissions flux and frequency at the same phase are obtained.The results are as follows: The characteristics of the phase-resolved spectra are different among three pulsars.For 1133+16,the spectra is steep at two sides of pulse profiles,otherwise flatter in the middle.For 0329+54 and 0834+06,the spectra are flat at the leading part and steeper at the trailing.According to those spectra characteristics,pulsars can be classified.For 1133+16,there are good correlations between radio emission and frequency at same phase,and when |Φ| > 3°,the correlation coefficient R>0.8 and chance probability P<0.03,which show that the radio emission of 1133+16 is power low spectrum.So,for 0329+54,when 4° > Φ > 3° and Φ < -3°,R>0.5,P<20%,and for 0834+06,those relationships are mutative and weakly at different phase,and means the radio emission may be not power low.

Using the similar formulas of the preference relation and the utility function,the author introduces the confidence relations and the corresponding influence functions that represent various interacting strengths of different families,cliques and systems of organization.Since they can affect products,profit,prices and so on in an economic system,and are usually independent of economic results,the system can produce a multiply connected topological economics.When the changes of the product and the influence are independent of one another,they may be a node or saddle point.When the influence function is large enough to achieve a certain threshold value,it will form a wormhole with loss of capital.Some shortages on the west economics are reviewed.Then combining with the east thinking-system,especially,Lao-Zhuang philosophy,the author proposes an east economics and its three principles:the common restraint or common promotion principle of the Yin-Yang and the Five-Elements,the whole principle of heaven-humanity-earth,and the cycle principle of some elements.Its major characteristics are entirety,balance and harmony.The highest aim is the principle of unified nature-human-society harmony.Further more,the author researches the corresponding mathematical theories and some concrete applications.The east economics is a nonlinear whole economics,and also a multiply connected topological economics related with various factors.These will redound to reconstruct of economics.

Through analyzing quantum communication in the token-ring network of three-particles entangled GHZ state，two articulation points are found and the fidelity is calculated.The calculation results show that the maximum fidelity is 1 for |a|=0,|b|=1 or |a|=1,|b|=0.For |a|=|b|=2/2,the fidelity is 0.5.The average fidelity is 0.67 at Bell-state measurement.With Von Neuman measurement,the fidelity relates to analyzer angle θ.If θ=π/4±kπ （k=0,1,2,…），the maximum fidelity is 1;if θ=π/4±kπ/2/（k=0,1,3,5…），the minmum of the fidelity is zero.The average fidelity is 0.5 .

The Modern astronomic theory of the Milky Way Galaxy is called ‘Density wave theory’.Density wave theory is used to make attempt in explaining the catastrophes and paleontological records.Coincidentally,but still disputed,each time solar system entered into the spiral arms corresponds to impact events,respectively.Furthermore,earth was heated up while traversing the spiral arms.Therefore,warmed climate would reach its climax at the end of a traversing.Calculations revealed that the spiral arms would impose an influence on earth and the solar system,which is astronomically slight but biologically considerable.Fossil records and geological survey corroborated such statement.Both abnormal events during the transition of Perseus Arm and Scutum-Crux Arm are discovered in this article.Research on lunar vestiges and craters is under process,in order to compensate earth’s geologic process which might efface records.

The final goal of scrambling for firm’s control power is obtaining the gains of control power.The firm’s control power is composed by the “core” of control power and the outer-control power.The “core” of control power is decided by property capital and it defines the allocation of the outer-control power.Family firm is the means of realizing familial goal by the family special interest group.The “core” of control power is grasped by family and will be inherited within family.According to the scale of family firm and the trust extent of family for professional manager,the outer-control power present dynamic distribution from being completely grasped by family to being completely authorized to professional manager.
