The article is devoted to the experimental study of the change in the capillary radius of cells of metal woven nets, depending on the degree of deformation of the structure of their weaving. The values of the measurements of the capillary radius of the cells are given as a function of the interlacing angle of the fibers of the nets. Recommendations are given on the possibility of using deformed nets in devices to ensure the continuity of the components of the fuel tanks of spacecraft.

The paper presents a theoretical and experimental study of experimental methods for the determination of deformability. Thus we determined the degree of deformation of copper wire by testing to traction, the fragility by means of fragility testing and the elongation of the spire sample. The experimental attempts have highlighted the fact that the properties of materials are determined with the help of the experimental methods. These The indicated test methods show the deformability of the material in the process ofplastic deformation and they are representative of physical simulation attempts.

Final Steady State

In this paper the liquid absorption under capillary pressure, or wicking, in cylindrical polymer wicks made of sintered polymer beads is studied experimentally and theoretically. Three different polymer wicks (made from Polycarbonate, Polyethylene and Polypropylene) and three different well-characterized liquids (Hexadecane, Decane and Dodecane) are used in the present experimental study. These experimental results are then compared with the predictions of the capillary model. The capillary and hydraulic radii used in the model are found to behave like two independent wicking parameters and are needed to be measured separately to improve the accuracy of the capillary model in predicting wicking in polymer wicks. Accurate measurement of the capillary radius ensured a good prediction by the capillary model of the final steady-state height in the large-pore wicks.

Illumination Mode

The tilted beam illumination method is used to improve the resolution comparing with the axial illumination mode. Using this advantage, a restoration method of several tilted beam images covering the full azimuthal range was proposed by Saxton, and experimentally examined. To make this technique more reliable it seems that some practical problems still remain. In this report the restoration was attempted and the problems were considered. In our study, four problems were pointed out for the experiment of the restoration. (1) Accurate beam tilt adjustment to fit the incident beam to the coma-free axis for the symmetrical beam tilting over the full azimuthal range. (2) Accurate measurements of the optical parameters which are necessary to design the restoration filter. Even if the spherical aberration coefficient Cs is known with accuracy and the axial astigmatism is sufficiently compensated, at least the defocus value must be measured. (3) Accurate alignment of the tilt-azimuth series images.
