This model gives an all-sided consideration on factors that influence the ASR. Results suggest that (1) Annual ASR has a progressive decrease trend from south to north; (2) the magnitude order of seasonal ASR is: summer>spring>autumn>winter; (3) topographical factors have robust effect on the spatial distribution of ASR, particularly in winter when a lower sun elevation angle exists; (4) the ASR of slopes with a sunny exposure is generally 2 or 3 times that of slopes with a shading exposure and the extreme difference of ASR for different terrains is over 10 times in January; (5) the spatial differences of ASR are relatively small in summer when a higher sun elevation angle exists and the extreme difference of ASR for different terrains is only 16% in July; and (6) the sequence of topographical influence strength is: winter>autumn>spring>summer.展开更多

Methods: Choose in February 2020 - February 2022 as A case study range, object to enter the HD joint HP treated in our hospital and uremic patients, quantity statistics for 100 cases, included in the category mode can be identified as double-blind principle, into group A and group B 50 cases respectively, which choose the mode of conventional intervention, the former seamless nursing intervention mode selection, Compare the two groups how to reflect the specific nursing effect. Results: Before and after intervention, the indexes of the two groups were compared, including quality of life, psychological level, inflammatory factors, etc., which showed that the observation group was better than the control group after nursing, indicating P value 0.05. Conclusion: Through the implementation of seamless nursing measures for HP combined with HD in the treatment of uremia patients, committed to physiological and physiological dual quality assurance, improve patients nursing satisfaction, the results of the study confirmed that it can be used for clinical promotion.展开更多
