Multiply charged Ti ions were accelerated to 80 MeV and 120 MeV, and directed through a 25μg/cm2 carbon foil. Ion currents before the foil were about 80 nA. The light emitted by the foil-excited ions was dispersed by a 2.2 meter grazing incidence GIM-957 XUV-VUV monochromator, built at CIAE, and equipped with a展开更多

Methods: a total of 120 patients who were treated for urethral calculi in our hospital in 2021 were randomly divided into observation group and control group, with 60 patients in each group. Both groups of patients will be treated with pneumatic lithotripsy under ureteroscope after entering our hospital. Patients in the observation group will receive comprehensive care, while those in the control group will receive general care. After the treatment, the operation, nursing satisfaction, postoperative complications and hospitalization of the two groups were compared. Results: the observation group showed more advantages in operation and nursing satisfaction. Conclusion: patients suffering from urethral calculi and receiving pneumatic lithotripsy under ureteroscope should use more advanced comprehensive care and the final treatment effect will be better, which is worth popularizing.展开更多

Spectral lines emitted from fifty- three excited energy levels were observed in the wavelength range 120—220 ?, among which eleven lines were new. Our experimental results show good agreement with the results of laser plasma experiments, and are in reasonable agreement with theoretical calculations.展开更多
