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: 94 patients who came to our center to treat HIV infection from February 2019 to February 2021 were randomly and evenly divided into two groups: the control group and the experimental group, with 47 patients in each group. Among them, the control group was treated and cared according to the normal nursing and psychological intervention methods, while the experimental group was given more targeted intervention based on the theory and method of positive psychology. After a period of nursing, the intervention effects of different nursing methods were evaluated, and the psychological stress state and compliance of two groups of patients were emphatically analyzed. Results: before the intervention, the SCL-90 MOS-HIV scores of the two groups were relatively high, and there was no significant difference (P>0.05). After the intervention, the SCL-90 score of the observation group was lower than that of the control group, and the MOS-HIV score was higher than that of the control group, and the difference was statistically significant (P < 0.05). Conclusion: according to the experimental results, the nursing intervention method based on positive psychology can have positive significance for AIDS patients with HIV virus, especially in improving patients' stress psychology and optimizing their compliance.展开更多

The X-ray spectra were measured by Si(Li) detectors with effective energy ranging from 1 keV to 60 keV. The results show that, the X-ray emission from the formed HA is closely correlated with the charge state of the projectile ions, and weakly correlated with the velocity of the projectile ions. For example, it was found that when Ar^18+ ions interact with Be-target, the yield of K X-ray with character energy of 3.0 keV is 7.2×10^-3 per ion, which is two times and 5 order of magnitude higher than those in the interactions of Ar^17+ and Ar^16+ ions respectively. When Ar15+ ions interact with the same targets, the Argon K X-ray would be too feeble to be detected. The X-ray yield with single ion in this experiment can be represented by the following equation,展开更多

We altered the projectile kinetic energy from 150 keV to about 400 keV. The X-ray excited by the projectile with the surface is shown in Fig.l, and a threshold of the projectile kinetic energy for this excitation is observed. Combining the colliding theory of classic electrodynamics with the concept of quantized orbits, we crudely give this threshold energy Tm as follows,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
