Reductive group actions on affine quadrics with 1-dimensional quotient: Linearization when a linear model exists
      
A linear model for a given action is a linear orthogonal action with the same orbit types and equivalent slice representations.
      
We prove that if a reductive group action on an affine quadric with a 1-dimensional quotient has a linear model, then the action is linearizable.
      
Using the path model and the theory of crystals, we generalize the concept of patterns to arbitrary complex semi-simple algebraic groups.
      
In the model situationD is the Siegel disc,S is the manifold of Lagrangian subspaces andG is the symplectic group.

In this poper,the author offers three new formulae for the construction of waterlines and curves of sectional areas,together with a simple method in the derivation of such curves for new designs from the parent ships.Last- ly,numerical values are tabulated corresponding to the rations coefficients in these formulae,being calculated from actual experimental data of Todd's “60”and“57”ship model series.

The horizontal variation of temperature lapse rate being taken into consideration, the author proposes a three-parametric model for weather numerical forecasting. The three parameters are the height of the mean iso baric surface (near 500 mb surface), the temperature of the same surface, and the temperature of 1000 mb surface.

Considering the nucleus as an axial asymmetric quantum mechanical system, we have discussed the rotational spectra of even-even nuclei under the adiabatic approximation. The following results are obtained.1. From the detailed analysis of low-lying energy levels of ten nuclei, rotational spectra of axial asymmetric nuclei definitely exist. The theoretical values of energy levels agree with experimental results very well. (See Fig. 1)2. We have obtained the three principal moments of inertia, (?)1, (?)2 and (?)B,...

Considering the nucleus as an axial asymmetric quantum mechanical system, we have discussed the rotational spectra of even-even nuclei under the adiabatic approximation. The following results are obtained.1. From the detailed analysis of low-lying energy levels of ten nuclei, rotational spectra of axial asymmetric nuclei definitely exist. The theoretical values of energy levels agree with experimental results very well. (See Fig. 1)2. We have obtained the three principal moments of inertia, (?)1, (?)2 and (?)B, of ten nuclei (Os190, Os186, W183, Er168, Er166, Dy150, Gd156, Gd154, Pu283, Pu240).3. The relation among the throe moments of inertia, as predicated in Eolir's model, is proved to be incorrect. According fo Bohr's theory, one should haveThereforeBut the values of (?)1, (?)2, and (?)0, deduced from experiments do not satisfy this relation. (See Fig. 3)

把原子核看作一非轴对称量子力学体系,在绝热近似下,考虑了其转动激发能谱。我们只讨论了偶偶核。计算及讨论表明: (1)原子核,特别是重核,肯定存在着非轴对称转动能谱,从我们仔细计算过的十个原子核能谱来看,理论值和实验值符合得很好,(见图1),大多数与实验值的偏离≤1%。 (2)我们第一次求得了原子核(Os~(190),Os~(186),W~(132),E~(166),E~(165),Dy~(160),Gd~(156),Gd~(154),Pu~(238)和Pu~(240))的三个主转动惯量θ_1,θ_2和θ_3。(表1). (3)原子核转动惯量之间并无A.Bohr理论所指出的关系。按照Bohr理论, (θ_1/θ_3)~(1/2)-(θ_2/θ_3)~(1/2)=1 但我们从实验求得的θ_1,θ_2和θ_3并不满足上述关系式(见图3)。
