Objective: To analyze the impact of the healthcare roundtable model on the major disease perceptions and competencies of cardiovascular nursing staff. Methods: Forty female nursing staff working in the hospital from April to june 2023 were selected and were randomly divided into a control group and an observation group, with 20 in each group. For 60 days, the control group used the conventional learning and communication model and the observation group used the medical and nursing roundtable model. The cognitive scores of cardiovascular disease-related knowledge, competency scores, and satisfaction with the learning and communication model before and after the implementation of the model in both groups were compared. Results: After the implementation, the cognitive scores related to cardiovascular disease-related knowledge, competency scores, and satisfaction with the learning and communication model in the observation group were significantly higher than those in the control group (P < 0.05). Conclusion: The healthcare roundtable model improved the knowledge and competence of cardiovascular internal medicine nursing staff in major diseases, and it is worth popularizing.

[目的]Jag S是一种新型可用于调控水土流失的高分子化学材料,揭示Jag S对降雨入渗的化学调控效应,为黄土坡面水土流失治理提供科学依据。[方法]采用人工模拟降雨试验研究Jag S对黄土坡面入渗调控效应。[结果](1)撒施Jag S坡面入渗率随降雨过程的变化趋势与裸坡相似,起初皆随降雨历时的延长先快速减小,随后趋于稳定状态;(2)撒施Jag S的坡面和裸坡相比,初始产流的时间提前,入渗率减小速率较大,达到稳渗阶段所用的时间少,且前期入渗率小于裸坡坡面前期入渗率,但稳渗率大于裸坡;(3)撒施Jag S坡面的入渗量明显高于裸坡的入渗量,在各个剂量下,入渗量均随坡度的增加而减小,随雨强的增加而呈现递增变化趋势。[结论]因此撒施Jag S可有效增加土壤入渗和强化入渗效应。强化入渗效应的Jag S剂量顺序依次为:1g/m2>3g/m2>5g/m2。
