 growth
 Complexity of Homogeneous Spaces and Growth of Multiplicities We give a representation-theoretic interpretation of this number as the exponent of growth for multiplicities of simple G-modules in the spaces of sections of homogeneous line bundles on G/H. A necessary and sufficient geometric condition on the growth of the boundary of approximate tiles is reduced to a problem in Fourier analysis that is shown to have an elegant simple solution in dimension one. We prove a Tauberian theorem of the form $\phi * g (x)\sim p(x)w(x)$ as $x \to \infty,$ where p(x) is a bounded periodic function and w(x) is a weighted function of power growth. A complex Radon measure μ on ?n is said to be of at most exponential-quadratic growth if there exist positive constants C and α such that. 更多

It is said that Pinus massoniana Lamb, which growing in the Kwangtung province is of two forms, i.e., one possessing more resin and the other with less resin. In the present paper, both the wood structure and the physico-mechanical properties of the two form timbers which were collected from the northern part of the province have been preliminarily studied. They are about thirty years old. According to the wood anatomical characteristics, these forms may be distinguished as follows: the first form comparing with the second form has wider ring-width, lower late-wood percentage, thinner tracheid-wall thickness and larger lumen-width, shorter tracheid-length, more rays and more radial resin ducts, less in numbers of tangential wall pits on late-wood tracheids, shallowly dentate ray tracheids, and more window-like pits per cross-field. Above all, the ring width and the tracheid length are the salient features. Among the physico-mechanical properties of the two forms of timbers, only both the strength in tension parallel to the grain and the shearing strength parallel to the grain have reliable differences. Moreover, the strength index, the strength/weight ratio and the height-growth rate are higher in the second form than which in the first one. In comparison with the race from other localities, the Masson pine timbers grown in the northern part of Kwangtung are the strongest in the main strength properties. 本文初步研究粤北乐昌大源林区近30年生馬尾松两个变型——“油松”和“糠松”的木材构造和物理力学性貭。依照木材解剖特征,将两个变型区别如次:油松的輪寬較大,晚材率較小,管胞壁厚稍小而腔闊稍大,管胞长度較短,木射线略多与径向树脂道較多,此外軸向管胞切向壁上具緣紋孔数目較少,射线管胞內壁鋸齿发育程度較浅,交叉場紋孔数目略多;糠松則相反。两者的主要差异为輪寬与管胞长度。油松与糠松两者的木材物理力学性貭,仅順紋拉力和順紋剪力有可靠的差异。此外,后者具有稍高的强度指标、貭量系数以及較大的树高生长。又粤北馬尾松木材的貭量系数,远胜他地同种松木,其主要力学指标較高,生长較快。 << 更多相关文摘
