What\'s more, different intervals of UV have their own characters in influencing DNA: the damage to some bases by UVA may be more serious than that by UVB, and UVB did more severe damage to some deoxyribose than UVA; however, as far as the pyrimidine bases are concerned, the damage by UVB is by far more serious than that by UVA. These results may indicate that there are preferential damaging sites on DNA molecules caused by UVA and UVB irradiation. Moreover, with UVA or UVB irradiation for a long time, the photoreactivation of DNA occurred. The serious damage to deoxyribose and bases by UVB and UVC may confirm the conformation of cyclobutane pyrimidine dimers and (6-4) photoproducts.

而不同波段紫外辐射对DNA的损伤各具特点并且差异明显，UVA对一些碱基的损伤比UVB要严重，而UVB在对脱氧核糖和磷酸盐的损伤上又比UVA要严厉，但就嘧啶碱基来说，UVB对它的损伤远大于UVA，这似乎表明了不同的紫外波段对生物大分子DNA的损伤是有选择性的。

We wish to suggest a structure for the salt of deoxyribose nucleic acid.

我们希望建议一个结构为deoxyribose 核酸盐。

After experiments, we got some results as the following:1.Induced by semi-conductor laser, solid DNA changes as below: 1the deoxyribose-phosphate backbone vibrations in DNA decreasing, these bands are at 884~890cm~(-1),1112cm~(-1) and 1168cm~(-1). 2 deoxyribose and C-O stretch vibration in d increasing, there are new bands occurring at 1436cm~(-1) and 1072cm~(-1), the intensities of these bands at 1466cm~(-1) and 1030cm~(-1) increase.
