| 1. | Most marine plants can live only in the photic zone .
海洋植物多半只能生活在透光层里。
|
| 2. | It is generally assumed that the photic zone extends to the depth at which the light intensity is reduced to 1% of the value at the surface .
通常认为光照带伸展到光强度降低为表面值为1的深度。

| 7. | Objective to study and compare photic stabilities among extracted black rice , amaranth and grape pigment from natural products
摘要目的从天然产物中提取黑米、苋菜红、葡萄红这三种花青素类色素，并比较它们的光稳定性。
|
| 8. | Methods to study the photic stabilities of these three types of pigment in an uniform environmental condition , using the same radiation lamp - house with the same illuminance
方法在统一的环境条件下，使用相同的辐射光源、照度，在近似相同的初始吸光度值下，对这三种色素的光稳定性进行比较研究。
|
| 9. | When the illuminance rose , the photic decomposition rates of the natural anthocyan pigments rose as well , but there was no linear relation between photic decomposition rate and illuminance
随着照度的增大，花青素类色素的光降解速率也增大，但光降解速率常数的改变和照度之间不存在线性对应关系。
|
| 10. | Results the natural anthocyan pigments were relatively stable under the radiation of incandescent lamp , whereas their photic decomposition rates became faster under the radiation of high - pressured mercury lamp
结果花青素类天然色素在白炽灯下较为稳定，而在高压汞灯照射下，光降解速度明显加快。
