  volume comparison
An extension of Günther's volume comparison theorem
      
The aim of this note if to give an extension of a classical volume comparison theorem for Riemannian manifolds with sectional curvature bounded above (see Günther, P.
      
We prove Hessian comparison theorems, Laplacian comparison theorems and volume comparison theorems for Finsler manifolds under various curvature conditions.
      
We also show that the dimension of the linear space of polynomial growth harmonic functions is finite if a volume comparison condition and a mean value inequality for nonnegative subharmonic functions hold in sufficiently large parts of each end.
      
Its proof is based on analyzing asymptotic structures of such manifolds at infinity and a volume comparison theorem.

The spinal cords of three men, nine cats, three dogs and four rabbits were chosen for the present investigation. It was found that the thoracic segment of the spinal cord is longer than the other segments in man and animals. The volume of the gray substance in the lumber enlargment are larger than that in the cervical enlargment in man, cat, dog and rabbit, The cross—section areas of the white substance of the spinal cord in man increase clearly at the cranial level but that of the rabbit does not.Based on the measurements we found that the move of the gray substance anteriorly in man and cat may be the mark of evolution of the mammals. Perheps the spinal eord of eat is a satisfectory specimen in neuro anatomical and neurophysiological laboratory.

本文选用三条人的脊髓,九条猫的脊髓,三条狗的脊髓,四条免的脊髓进行了研究。1.人脊髓最长的脊髓节是第三胸脊髓节(Th3),猫是第十二胸脊髓节(Th12),狗是第四颈脊髓节,兔是第三腰脊髓节(L3)。在人和动物,一般来说脊髓胸段都比脊髓其它段长。人和狗的脊髓颈段比腰骶段(L-S)长。猫和兔的腰骶段比颈段长。2.灰质体积的比较是人、猫、狗、兔的腰膨大均比颈膨大的灰质体积大。人的胸段灰质体积最大。3.人的脊髓白质面积近颅则有明显的增大,兔的脊髓白质面积近颅侧没有明显的增大。4.一般来说,动物脊髓前角的体积都大于后角,但是人脊髓颈段和胸段前角的体积小于后角。动物脊髓中间带的体积比人的大。5.人脊髓白质后索的面积比前索面积大,但是兔脊髓白质后索的面积比前索面积小。我们发现人和猫的灰质向前移动是动物进化在脊髓的标志。可能在神经解剖和神经生理实验方面猫的脊髓是比较满意的实验对象。

The structure of nioboborate glass was studied with a high power ro- tating anode type CuKα X-ray diffractometer.Based on the warren equation, a new way resolving the redical distribution function was established.It was comparatively simple,especially for the analysis of RDF of polycompo- nent glass system because it was concerned with fearer factors. Using this way the structure model of nioboborate glass was ob- tained.A loose construction is the feature of these glasses.That is to say the valume of structure unit in the glass is sufficientlylarge,there exist agre- at numberof wider hollows in the structure.This is the reason why the niobo- borate glass has high dispersion and comparatively low density.Besides this, some glasses in the system also have high conductance.

本工作用大功率转靶 X 射线衍射仪研究铌硼酸盐玻璃结构;根据 B·E·War-ren 方程,建立了一种计算玻璃原子径向分布函数(RDF)的解析方法。因其涉及因素少,计算简便,适用于多元系统玻璃结构分析。应用本方法,已获得了 Nb-B-K 系统玻璃的比较完整的三维结构模型。模型表明,这种玻璃结构松散,克分子体积比较大,并具有较高的自激发极化率。于是铌硼酸盐玻璃的低密度、低折射率和相对高的色散,以及较高的电导率等特殊性质的结构因素得到了证实。
