表皮生发层

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。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
