It is suggested that mechanisms protecting epidermis of squamata species from UVB damage may involve in (1) Physical defensive mechanism: the death epidermal layer limited UVB transmitting to the viable cells;(2) Biochemical defensive mechanism: up-regulated CAT may protect skin from reactive oxygen species which may induced by UVB. Moreover, the lipid and proteins in the β-, meso- and α-layer may absorb incident UVB and formed damaged products that were limited in the original site;(3) Cellular defensive mechanism: quick initiating of proliferation of the germinal cells and forming of the new epidermis and shedding out the damaged epidermis shortened the damage process and restricted the damage area.

1物理性防御：角质层和中层阻挡绝大部分UVB透过，最大限度地减轻生发层的损伤；(2)生化性防御：通过上调CAT活性以减轻LVB诱导的活性氧对表皮的损伤，同时角质层蛋白质和中层脂类可吸收UVB，且形成的有害产物被局限于原位；(3)细胞性防御：通过迅速启动再生修复过程形成新的表皮，及时蜕去积累了脂类过氧化产物、受损蛋白质和晒斑细胞等的受损表皮，有效防止损伤的持续和蔓延。

Effect of sulfurization time, water content, oil as well as sulfur on spontaneous combustion of iron sulfide is investigated on the same sulfide formed from Fe2O3. It indicates that long sulfurization time, some oil, sulfur as well as good ventilation condition could accelerate oxidation and temperatures rise, but uncertain water content and poor ventilation condition lessen the spontaneous combustion tendency.

The basic data obtained from the experimental research were calculated and disposed with computer and concluded an important principle of Li〓O by silicon thermoreduction. The factors affected the reduction such as temperature, pressure and time were dicribed by methematical equations. The relation ships of reduction rate with temperature, pressure and time were directly expressed by three-dimension figures. The relating mathematical equations described the process derived from research were proved to be coincided with the practice. Therefore, the obtained results were accurate and reliable and of important value.
