ray aberration
1.Based on the three-dimensional ray tracing and aberration calculations,the off-axis mirror line focus system used in SERC Rutherford Appleton Laboratory is analyzed.
2.Influence of chronicγ-ray radiation on chromosome aberration,micronucleus and transformation frequency in peripheral blood lymphocytes in rabbits induced by acute radiation
3.Chromosome aberration analysis on medical X-ray workers
4.Results ① 95% of the types of chromosome aberration in all X-ray groups and normal controls were observed as acentric aberration. However, the chromosome somatotype aberration in X-ray groups was all 1 to 2 times higher than that in controls.
5.On the basis of analysis of samples of Qin Shi Huang Mausoleum colour drawings on the bronze chariot and horses components,the analogue test is made on the humidity to preserved surrounding environment of bronze chariot and horses. After changing environmental humidity, temperature and illuminating with or without ultraviolet ray, the changing situation of chromatic aberration Δ E according to the study of four typical mineral pigments including of white, blue, green pigments is inspected.
6.The Analysis of Distribution of the Chromosome Aberration Breakpoints from Medical Diagnostic X-ray Workers
7.Study on the application of chromosome aberration frequency for health inspection in X-ray workers
8.The cell survival rate and the chromosomal aberration induced by N-methyl-N-nitro-N-nitriosoguanidine (MNNG), mitomycin C (MMC) and ethyl methanesuiphonate (EMS) in V79 cells and its γ-ray-sensitive mutants (irs5 and mil) were observed in this study.
