  small hole
Indefinite metric and scattering by a domain with a small hole
      
For the problem of plane waves scattered by a domain with a small hole, we suggest a model based on the theory of self-adjoint extensions of symmetric operators in a space with indefinite metric.
      
Since the discharge unit is a nonuniform gas-dynamic system (the gas is fed through a small hole into a chamber of limited size), there is a possibility of generating vortex flows that intensively mix the gas.
      
The principal terms of the asymptotic expansion of a resonance (quasi-eigenfrequency) are derived for waveguides coupled via a small hole.

The Permeability of clayed soil is depended first on the hole dimensions, and secondly on the amounds of the holes. Based on the tests of determining holes by the mercury-injection method and the tests about the permeability of the Luochuan loess layers, this paper sifted out the independent variables by using the curve-analysis method and the progressive regression method, and has discovered that the smallest permeable aperture of the loess layers is more 5 mm. From this it has calculated that the thickness...

The Permeability of clayed soil is depended first on the hole dimensions, and secondly on the amounds of the holes. Based on the tests of determining holes by the mercury-injection method and the tests about the permeability of the Luochuan loess layers, this paper sifted out the independent variables by using the curve-analysis method and the progressive regression method, and has discovered that the smallest permeable aperture of the loess layers is more 5 mm. From this it has calculated that the thickness of the combined water in the loess layers is about 9000 times larger than the water molecule diameter.

粘性土的透水性首先取决于孔隙的大小,其次是孔隙的多少。本文在对洛川塬黄土地层进行水银测孔试验和渗透试验的基础上,用曲线图分析法及逐步回归分析法对自变量进行筛选,找出了黄土地层透水的最小孔径大于5μm,并以此推算出黄土地层中结合水的厚度约是水分子直径的9000倍。文中还建立了描述渗透系数与透水孔隙孔容关系的随机数学模型,开辟了一条通过水银测孔取得粘性土渗透系数值的新途径。
