The article presents theoretical studies of filtration transport of moisture through capillaries of woody plants that is determined by humidity gradients. The emerging humidity fields and the magnitude of the gradients significantly affect the growth and development of woody plants biomass. The aim of theoretical research was to use mathematical tools of operational calculus that provide an opportunity to consider the filtration of moisture through the capillaries of wood materials using a third-kind boundary condition, when the substance is exchanged with the environment at the considered boundary. As a result of the use of Laplace transform a mathematical model for studying the movement of moisture in the capillaries of woody vegetation through filtration transport has been obtained. Modelling of a moisture transport process in wood materials is an important tool in theoretical and experimental studies. This is particularly important for conducting long-term experimental studies of the site quality of stand of trees from the technogenic impact of vehicles on roadside ecological systems.

木本植物毛细血管水分过滤运动的理论研究

本文介绍了水分通过由湿度梯度确定的木本植物毛细血管的过滤运输的理论研究。新兴的湿度场和梯度的大小显着影响木本植物生物量的生长发育。理论研究的目的是使用运算微积分的数学工具,当物质在所考虑的边界处与环境交换时,该工具提供了一个机会来考虑使用第三类边界条件通过木质材料的毛细管过滤水分。作为使用拉普拉斯变换的结果,已经获得了用于研究通过过滤传输在木本植被毛细血管中的水分运动的数学模型。模拟木质材料中的水分传输过程是理论和实验研究的重要工具。这对于从车辆对路边生态系统的技术影响对林分场地质量进行长期实验研究尤为重要。
