Both the inertia term and coupling term are considered in the dynamic coupled problem. The formulation of the problem by a statistical second-order two-scale （SSOTS） analysis method and the algorithm procedure based on the finite-element difference method are presented. Numerical results of coupled cases are compared with those of uncoupled cases. It shows that the coupling effects on temperature, thermal flux, displacement, and stresses are very distinct, and the micro- characteristics of particles affect the coupling effect of the random composites. Furthermore, the coupling effect causes a lag in the variations of temperature, thermal flux, displacement, and stresses.展开更多

Methods: 62 patients with dysphagia caused by cerebral apoplexy were selected as test subjects, and the treatment time in our hospital was from January 2021 to January 2022. According to the method of touching the ball, 62 test subjects were divided into 2 groups, with 31 test subjects in each group. Routine nursing intervention and IOE management nursing intervention were implemented respectively. The scores of dysphagia, nursing satisfaction and quality of life of the two groups were observed. Results: after nursing intervention, the swallowing disorder scores of the two groups were compared. The nursing intervention group was lower than the routine group (P 0.05);The quality of life and nursing satisfaction in the nursing intervention group were higher than those in the routine group (P 0.05). Conclusion: the clinical nursing effect of using IOE tube for patients with dysphagia is more ideal and can be widely used in clinic.展开更多
