And use the prior and more consummate ways to carry through vaneaccidence design, These ways have own technology points and disadvantage, In this paperstressly discuss the momentum-element theory way, this way was developed in the basic ofthe two ahead ways, and it overcome their defect. It also use element theory to deal withvane design. In the vane designing and aerodynamical characteristic calculating they bothrelate with intervene gene, so the keystone is to carry through the intervene gene in twocase, thereout to do the vane design and aerodynamical characteristic calculating.

Given a finite training sample set, according to the proposal of establishing a Local Most Entropy probability density function to estimate the number of cluster a method for estimating 〓 is proposed, where a complicated method based on Maximum Likelihood Cross-Validation is replaced by Chebyshev inequality.

Based on momentum balance and the law of momentum conservation, two new graphic methods are developed to determine the pre-impact vehicle momentum or collision speed in this paper.

However, the single closed loop controlling only can make the ratio a certain number, the defect is it could not eliminate the spontaneity surge of main momentum, so minor momentum changes when the main momentum fluctuates, the total flux could not remain fixedness.

After the discussion of the constrain condition for Bose-Einstein statistics in NC Phase space, the Hamiltonian operator of the two dimensional charged harmonic oscillator in external electric field was discussed.

In the process of moving from single-sustenance to double- sustenance, the angel of body tends to enlarge; in the process of moving from double-sustenance to single-sustenance, the angle of body tends to decrease; when the right leg is kicking on the ice, the center of gravity is just moved to the upper point of fulcrum, which means the center of gravity is vertical to fulcrum, while the left leg starts to kick on the ice when center of gravity completely surpass fulcrum; right knife touches the front ice of the supporting foot, the left knife touches the interior and front ice; small momentum variation coefficient and good effect of momentum move show the rationality of action and abundance of

In the modified Newtonian mechanics, the law of conservation of momentum and the law of conservation of energy become invalid; instead, the inherent momentum and inherent kinetic energy can be defined to make the law of conservation of inherent momentum and the law of particle inherent kinetic energy valid.

Because of the space is uniform,So that the momentum conservation is occurrence in nature,it explain the momentum conservation is a attribute of the space.

The results are consistent with the interpretation that positive intangible information tends to trigger institutional herding on the buy side.3. The securities Investment Funds act as momentum traders in bear market while as contrariant traders in bull market. Further analysis reveals that momentum trading by investment funds intensifies stock return momentum but stock price experiences a long-term reversal. It indicates return momentum results from mispricing instead of risk. The securities Investment Funds hamper market efficiency when they act as momentum traders.4 Both momentum trading and herding behavior intensify market anomalies and hamper market efficiency. However, momentum trading or herding behavior is the only one of the many aspects of the institutional investor.

In chapter 4, by AREELS, the Generalized Oscillator Strength Density Spectra were measured in the energy region from 56 to 66eV, with the incident energy 2. 5 keV and energy resolution 80 meV, at scattering angles from 0°to 6°, corresponding to the momentum transfer K〓=0.03~2. 01 a. u. The Fano profile parameters f〓 and q for the optically allowed transition 〓(0, 1)〓P°and the optically forbidden transitions 〓(1, 0)〓S〓and 〓(1, 0)〓D〓 were obtained as a function of K〓. With the hyperspherical coordinate wavefunctions, the dynamical correlation are discussed qualitatively. So, a new experimental way to study dynamical electron correlation effect is opened.In chapter 5, the widely used R-matrix theory was introduced. Then, the GOSDS for the optically allowed excitation series (1s〓)〓S〓→〓(0, 1)〓P°(n=2-4) were calculated by this method, and the Fano profile parameters f〓 and q were obtained sequently. So the electron correlation effect can be described by these parameters quantitatively, and the theoretical results were compared with our AREELS experimental results.
