A comprehensive study on Raman spectroscopy with different excitation wavelengths, sample sizes, and sample shapes for optic phonons (OPs) and acoustic phonons (APs) in polar and non-polar nano-semiconductors has ...A comprehensive study on Raman spectroscopy with different excitation wavelengths, sample sizes, and sample shapes for optic phonons (OPs) and acoustic phonons (APs) in polar and non-polar nano-semiconductors has been performed. The study affirms that the finite size effect does not appear in the OPs of polar nano-semiconductors, while it exists in all other types of phonons. The absence of the FSE is confirmed to originate from the long-range FrShlieh interaction and the breaking of translation symmetry. The result indicates that the Raman spectra of OPs cannot be used as a method to characterize the scale and crystalline property of polar nano-semiconductors.展开更多

Methods: a total of 80 patients with neck shoulder lumbago and leg pain in our hospital from January to June 2021 were randomly divided into two groups by number table method. The control group received conventional western medicine nursing, the experimental group carried out conventional western medicine nursing combined with traditional Chinese medicine nursing. Quality of life score, neck and shoulder pain score, lumbar and leg pain score, average length of stay and rehabilitation effect were compared between the two groups before and after nursing. Results: the score of quality of life in the experimental group was higher than that in the control group, and the score of neck and shoulder pain and lumbar and leg pain was lower than that in the control group. The average hospital stay was shorter than that in the control group, and the rehabilitation effect was higher than that in the control group, with significant difference (P < 0.05). Conclusion: the combination of Traditional Chinese and western medicine nursing intervention for patients with neck, shoulder and waist and leg pain is effective in relieving neck, shoulder and waist and leg pain, reducing the occurrence of complications, shortening the length of hospital stay, with high clinical safety and feasibility, worthy of promotion and use.展开更多
