The Outcome shows that the influences ofcoupling effects of thrust magnetic bearing and tilt of journal on critical rotational speeds ofsystem are very large, and the stability of system reduces greatly. That shows it is important thatthe influence of coupling effects of thrust and radial magnetic bearings due to the rotor tiltingmust be considered in the study of rotor-magnetic bearings system dynamic characteristics, and alsoshows it is important that the rotor is mounted and debugged in ideal alignment of magneticbearings.展开更多

Methods: the nursing effect of stroke patients in our hospital was retrospectively analyzed, and the observation objects were selected: stroke patients confirmed by neurosurgery and receiving treatment in our hospital. The observation objects were selected from September 2019 to September 2021, with a total of 70 cases. The groups were identified by random double-color ball method, 35 patients were included in the control group, routine rehabilitation nursing measures were implemented, 35 patients were included in the observation group, and routine rehabilitation + traditional Chinese medicine rehabilitation nursing were implemented. Comparing different rehabilitation nursing on patients neurological function, limb function recovery, TCM symptom score of limb disorder, cognitive function, rehabilitation self-efficacy, patients satisfaction with nursing service. Results: compared with the control group, the observation group had low nerve score, significant limb function recovery effect, low TCM symptom score, high cognitive function score, high rehabilitation self-efficacy score and high patient satisfaction score (P < 0.05). Conclusion: traditional Chinese medicine rehabilitation nursing for stroke patients can effectively improve the neurological function of patients and improve the living standard of patients.展开更多

In order to meet the needs of China's high-speed railway construction, China Railway Corporation launched a major scientific research project "Research on Key Technologies for the Construction of Long-span Simply Supported Beams for High-speed Railways" in 2016. Beijing Railway Fangshan Bridge Co., Ltd. is mainly responsible for the manufacture of 40-meter full-scale test beams, and template assembly is an important factor affecting the quality of the test beams. The summary of formwork assembling construction technology for 40-meter full-scale test beam can provide technical guarantee for formwork assembling construction for the production of high-speed railway long-span simply supported beam in the future.展开更多
