 It is also shown that on the nilmanifold $\Gamma\backslash (H^3\times H^3)$ the balanced condition is not stable under small deformations. For $\gamma\in\mathbb{R}$ let $C(\gamma)$ be the set of all $f\in{\mathcal S}^\prime$ for which$\sum_{n=0}^{\infty}\,|(f,h_n)|\,(n+1)^{\gamma}>amp;lt;\infty$, where $(h_n)_{n=0,1,\dots}$ is the orthonormal base of Hermite functions. We show that $C(\gamma)\subset S_0$ if and only if $\gamma\geq\frac{1}{4}$ and that $S_0\subset C(\gamma)$ if and only if $\gamma\leq{-}\frac{1}{4}$. Using these results we give an explicit solution of the problem of optimal reconstruction of functions from Sobolev's classes $W^{\gamma}_{p}(M^{d})$ in $L_{q}(M^{d}), 1 \leq q \leq p \leq \infty$. This result generalizes the characterization of Fourier series of distributions with a distributional point value given in [5] by $\lim_{x\rightarrow\infty}\sum_{-x\leq n\leq ax}a_{n}e^{inx_{0}}=\gamma\ (\mathrm{C},k)\,$. 更多
 Based on statistical analysis and x~2 test of the field data, it is found that Gamma and Weibull distribution are suitable to express the distribution of wind wave run-up on slope, and the distribution parameters depend on relative depth and slope. According to the suggested theoretical distribution, the average values of the 1/n th highest wave run-up and the expected values of extreme for a sample of size N are computed while the results agree with the field data satisfactorily. Finally, an empirical...

According to the suggested theoretical distribution, the average values of the 1/n th highest wave run-up and the expected values of extreme for a sample of size N are computed while the results agree with the field data satisfactorily. Finally, an empirical expression for wind wave run-up height is presented. 本文根据实测爬高分布资料的统计分析,以及基于对几种常用理论分布的适度检验,建议采用一元三参数伽玛分布(包括韦伯分布)为爬高分布.实测资料还表明分布参数与堤坡坡度及堤前水深有一定关系.根据建议的理论分布计算了部分大爬高均值以及最大爬高的估值,並与实测资料进行比较.最后,基于实测资料分析,给出了确定不规则波爬高的经验公式. Eesponse of the inner magnetosphere and the ionosphere of middle and low latitudes to Bz variations of the interplanetary magnetic field is studied. It is pointed out that variations of the large-seale convective electric field in the magnetosphere arising from Bz variations will penetrate into the inner magnetosphere, and then map into the middle-low latitude ionosphere along magnetic field lines, producing a characteristic electric field and current system, which will distort the Sq current system and produce... Eesponse of the inner magnetosphere and the ionosphere of middle and low latitudes to Bz variations of the interplanetary magnetic field is studied. It is pointed out that variations of the large-seale convective electric field in the magnetosphere arising from Bz variations will penetrate into the inner magnetosphere, and then map into the middle-low latitude ionosphere along magnetic field lines, producing a characteristic electric field and current system, which will distort the Sq current system and produce a measurable magnetic disturbance on the earth surface. Numerical calculation shows that when Bz<0,Sq current system Will shift eastward and toward high latitude, and a magnetic disturbance of a few gammas will be observed on the earth surface. This provides a posibility of diagnosing the state of solar wind and the magnetosphere by magnetic observations at middle and low latitudes. Besides, the above-mentioned mechanism can be used to explain some aeronomie phenomena in the equatorial region, such as variations of electron drift speed, equatorial magnetic anomaly, disappearance of equatorial-type sporadic E, etc.. 本文讨论了行星际磁场B_2分量变化时内磁层和中低纬度电离层的响应.指出B_2变化引起的磁层大尺度对流电场的变化在一定条件下有可能透入内磁层,并沿磁力线映射到中低纬度电离层,在那里产生电场和电流体系,从而使S_q电流体系发生畸变,并在地面磁场中反映出来.数值计算表明,当△B_2<0时,S_q电流体系的焦点向东和向高纬移动,地面磁场会观测到数伽马的变化.这就为中低纬地磁观测诊断磁层和太阳风状态提供了一种可能性.此外,本文还用上述物理过程解释了赤道地区一些高空物理现象,如B_2倒转时电离层漂移速度的变化,赤道磁场异常以及赤道q型偶现E层的消失等等. It is proposed in this paper that an exponential gamma distribution be used as the theoretical model for the flood extremum distribution. The density functi on of the exponential gamma distribution is derived based on gamma distribution:The exponential gamma distribution, or the frequency curve, is found by integration of the above equation and it is pointed out that P-Ⅲ and K-M type frequency curves are exponential gamma distribution curves under different specific conditions. 本文提出用指数Г分布作为洪水极值分布的理论模型。以Г分布为转换基础,导出了指数Г分布的密度函数 f(x)=β~α/Г了(a)(x-δ)α/b-1e(~(-β)(x-δ),1/b) 对上式积分推求得指数Г分布,即频率曲线。监指出P-Ⅲ型、K-M型频率曲线是在不同的特定条件下的指数Г型分布曲线。用实例说明该函数对洪水适应性较好。 << 更多相关文摘
