  gamma
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 $\lim_{x\rightarrow\infty}\sum_{-x\leq n\leq ax}a_{n}e^{inx_{0}}=\gamma\ (\mathrm{C},k)\,$.

The strong and weak points of some grade-sampling methods for uranium ores are discussed.The proposed sampling method is based mainly on the radiometric sampling of all lots checked with the material sampling of some lots of ore as reference standards.The regularized coefficients for gamma intensity of graded ore are first determined according to a statistical study of the results from radiometric sampling checked with the material lots of ore sampling. In so doing, by the radiometric sampling, the grade...

The strong and weak points of some grade-sampling methods for uranium ores are discussed.The proposed sampling method is based mainly on the radiometric sampling of all lots checked with the material sampling of some lots of ore as reference standards.The regularized coefficients for gamma intensity of graded ore are first determined according to a statistical study of the results from radiometric sampling checked with the material lots of ore sampling. In so doing, by the radiometric sampling, the grade of every lot of ore can be determined in time with relatively low error.

本文分析了对各种供矿矿石的取品位样方法的优缺点,提出了如下取样方案:以准确可靠的实物取样为基准,逆推放射性取样换算系数,消除系统误差;对所有供矿矿石进行放射性取样,既可降低偶然误差,又能及时地分批给出矿石品位。

A new radiometric-photometric sorting method for raising sorting efficiency of uraniferous ore is described.The equipment is mainly composed of 1011 type photometric sorter incorporated with radiometric measuring device for detecting gamma radiation coming from each piece of rock/ore by means of scintillation counters.The comparative tests between the radiometric-photometric sorting method and photometric method for the uraniferous ore of some mine were made.The results showed that the tailings from the ore feed amounting to 62-65% (weight) at the grade of 0.010-0.013% U could be rejected and the grade of the concentrate averaged 0.200% U as compared with 0.080% U of the ore feed.

本文所叙述的光电-放射性联合分选方法是在一台设备上相继进行光电分选与放射性分选以提高选矿效率的新方法。文中主要介绍了附加在1011M型光电分选机上的放射性测量装置和光电-放射性联合分选法的工作原理。对某铀矿样进行了联合分选和光电分选对比试验,结果表明,联合分选优于光电分选,联合分选可废弃铀品位为0.010~0.013%、产率为62~65%的尾矿,铀品位由原矿的0.080%富集到0.200%左右。

This paper researches into the problems of simulation for a shearer drum load by computer, in particular, studies the mathematical model of random simulation for a pick load.At present, foreign scholars suggested that Rayleigh random process for simulation of a pick load can be used. The paper proposes that Gamma-distribution may be adopted for this purpose if simulation time-interval is wider: otherwise random process should be suitable. Meanwhile a mathematical model for simulating radial force on the pick is set up. Further works, such as simulation of a shearer drum load, computer programs of random load on the shearer drum, and measurements for a specific one have been completed. Finally, an analysis is made on the results obtained by the methods above.

本文对采煤机螺旋滚筒负荷的计算机模拟问题进行了研究。特别是对截齿负荷随机模拟的数学模型进行了深入探讨。目前,国外提出用瑞利随机过程模拟截齿负荷。本文提出,当模拟时间间隔较大时,可以采用Gamma分布模拟截齿负荷;否则,可以用x~2随机过程模拟截齿负荷。同时提出模拟截齿径向力的数学模型。此后,对螺旋滚筒上的负荷进行了研究,编制了滚筒随机负荷的模拟程序。并对某矿井采煤机的实际负荷进行了模拟和实测。最后,对此进行了分析与评价。
