Under the laboratory environment which has no the measures of vibration isolation and constant temperature. the measuring accuracy of the transverse aberration is -1.2￣+1.1μm and repeated measuring accuracy is:-1.7μm< 3 σ <1.7μm.
The analysis shows, using the glass with typical optical properties as the base glass, both Na +/Li + exchanging and K +/Cs + exchanging are suitable for preparing a low chromatic aberration GRIN rod lens, while K +/Tl + exchanging and Na +/Ag + exchanging might produce a GRIN rod lens with much higher chromatic aberration.
The resolution of the designed optical system reaches 0.7 mrad which is close to eyes minimum resolution,the lateral chromatic aberration is less than 42 μm for visible light band,and the maximum distortion is less than 2%.
Critical stages of carcinogenesis such as acquisition of cell ability for invasion may be regarded as the genetic aberration of normal search migration: cancer cells perform an endless search but cannot make final choice.

The Database for Analysis of Quantitative Characteristics of Chromosome Aberration Frequencies in the Culture of Human Periphera
The data on spontaneous chromosome aberration rates in cultures of human peripheral blood lymphocytes obtained in the past 30 years have been collected to form a database.
No differences between sexes have been found with respect to either the total chromosome aberration rate or the rates of individual aberration types.
