The regional metallogeny is discussed, and the ore-forming fluid systems are classified in this article. It is proposed that the fluid ore-forming activities in the Jiangnan Uplift both in northern Jiangxi and southern Anhui have close relationships with the crust-mantle interaction and magmatic-tectonic activities. The types and scales of the mineralization on the both sides of the eastern Jiangnan Uplift were determined by fluid ore-forming systems and geological backgrounds.展开更多

Methods: this study was divided into groups, mainly focusing on 116 elderly patients in chronic rehabilitation department who were hospitalized in our hospital from June, 2020 to October, 2022. The observation group adopted high-quality nursing scheme and the control group adopted routine nursing scheme, and the nursing satisfaction of the two groups was compared. Depression and anxiety score;Nursing technology;Nursing environment and nursing knowledge. Results: comparing the observation group with the control group, it was found that the nursing satisfaction of the former was lower than that of the latter. Depression and anxiety scores were higher than those of the latter;Nursing technology, nursing environment and nursing knowledge are better than the latter. Conclusion: in the clinical nursing of elderly patients with chronic diseases treated by intravenous therapy, the provision of high-quality nursing services is beneficial to patients anxiety and depression, and has certain popularization and use significance.展开更多

The experimental results of a kind of glass between 300 and 800 K are presented.展开更多
