This pa.e. studies the influence of a finite container on an ideal *** tra.e.of the heat kernel (t) =exp, where a.e.the eigenvalues of the negative Laplacian -in Rn(n = 2 or 3), is studied for a general multi-connected bounded drum ft which is surrounded by simply connected bounded domains Ωi with smooth boundaries Ωi(i = 1,… ,m) where the Dirichlet, Neumann and Robin boundary conditions on Ωi(i = 1,…,m) a.e.considered. Some geometrical properties of Ω a.e.determined. The thermodynamic quantities for an ideal gas enclosed in Ω a.e.examined by using the asymptotic expansions of (t) for short-time t. It is shown that the ideal gas can not feel the sha.e.of its container Ω, although it can feel some geometrical properties of it.

The tra.e.of the wa.e.kernel μ（t） =∑ω=1^∞ exp（-iteω^1/2）, where {eω}ω^∞=1 a.e.the eigenvalues of the negative Laplacian -△↓2 = -∑k^3=1 （δ/δxk）^2 in the （x^1, x^2, x^3）-spa.e. is studied for a variety of bounded domains, where -∞ 〈 t 〈 ∞ and i= √-1. The dependence of μ （t） on the connectivity of bounded domains and the Dirichlet, Neumann and Robin boundary conditions a.e.analyzed. Particular attention is given for a multi-connected vibrating membra.e.Ω in Ra surrounded by simply connected bounded domains Ω j with smooth bounding surfa.e. S j （j = 1,……, n）, where a finite number of piecewise smooth Dirichlet, Neumann and Robin boundary conditions on the piecewise smooth components Si^＊（i = 1 ＋ kj-1,……, kj） of the bounding surfa.e. S j a.e.considered, such that S j = Ui-1＋kj-1^kj Si^＊, where k0=0. The basic problem is to extract information on the geometry Ω by using the wa.e.equation approach from a complete knowledge of its eigenvalues. Some geometrical quantities of Ω （e.g. the volume, the surfa.e.a.e., the mean curvuture and the Gaussian curvature） a.e.determined from the asymptotic expansion ofexpansion of μ（t） for small │t│.

海——微生物栖息的特殊环境。特殊的盐类成分,低温,高压,低浓度的有机物质,植物及动物区系的稀少等组成了微生物生命活动的广阔海洋区域一些主要生态特征。海洋中最初的微生物学研究,早在上一世纪就已进行了,但是它们局限于较狭小的任务——确定细菌在海洋中的存在及其组成。而伊萨琴科的卓越著作《北冰洋细菌的研究》奠定了阐明微生物在全世界海洋(约近15亿立方公里)的巨大水团内物质转化过程中作用的开端。这项工作是在1908年结束的,但是直到1914年才出版。这篇包括有关海区中微生物活动多方面资料的专论,确定了海洋微生物学多年的研究方向并使海洋微生物学发展成独立的科学部门。
