Abstract. The material presented here demonstrates the experience gained over the past two decades. The emphasis is made on solving the fundamental problems of vortex aerohydromechanics and thermal physics that are related to the construction science. One of the major objectives of this work is to arrange the research directions according to this subject with the intent of showing their inter-discipline character.
От первого отличается относительно более короткими внешними губными щетинками, более короткими спикулами и более дальним положением вульвы от переднего конца тела. От D. minutum новый вид отличается более длинным телом, менее стройным хвостом, более длинными спикулами и более близким положением фовей амфидов по отношению к переднему концу тела. От D. alternum новый вид отличается более коротким и толстым телом, менее стройным хвостом, более длинными спикулами, относительно более короткими щетинками и более близким положением фовей амфидов по отношению к переднему концу тела.
Abstract. The paper proposes mathematical model for unsteady-state moisture behaviour calculation of single-layer enclosing structures by means of moisture potential and discrete-continuous method. A formula for moisture potential value calculation for single-layer enclosing structure in any enclosing structure section, at any moment of time, under continuous control for temperature distribution, has been derived. Moisture transfer between the enclosing structure and ambient air is taken into account by means of third-kind boundary conditions. Temperature distribution is taken as constant during a month. The proposed method allows for moisture potential determination according to the proposed formula for every month. Calculation results obtained by the proposed method, well-known unsteady-state method and engineering method developed by V.G. Gagarin and V.V.Kozlov have been compared for single-layer enclosing structure made of aerated concrete. It was shown that average value calculation results disagreement does not exceed 7% for the proposed method and unsteady-state method. However, the proposed approach allows for moisture distribution determination using analytical expression, which is convenient for use in engineering practice.
