| 1. | Optical depth and optical path are often confused in the literature .
文献中光学厚度和光程时常混淆。 |
| 2. | Ultraviolet radiation ; two stream model ; optical depth
紫外辐射二流模式光学厚度 |
| 3. | Aerosol optical depth distribution over the pearl river estuary at 11 a . m . on 6 january 2005
2005年1月6日上午11时珠江三角洲地区的气溶胶光学厚度分布 |
| 4. | Aerosol optical depth is a measure of the opaqueness of air , and high values of aod indicate poor visibility
气溶胶光学厚度aod量度大气的透明度。高数值表示能见度较低。 |
| 5. | Aerosol optical depth ( aod ) is a measure of the opaqueness of air , and high values of aod indicate poor visibility
气溶胶光学厚度( aod )量度大气的透明度。高数值表示能见度较低。 |
| 6. | Neptune ' s rings do not fall into this neat dichotomy ; their optical depth lies between the two extremes
但是这简单的二分法却无法适用于海王星的星环系统，因为其光深度恰位于两极端之间。 |
| 7. | At the other extreme , the faintest known rings , such as jupiter ' s rings and saturn ' s outermost rings , have optical depths between 10 ? 8 and 10 ? 6
在另一个密度极小的极端情况当中，已知最模糊的行星环，如木星环与土星的最外环，其光深度只有10 - 8到10 - 6 。 |
| 8. | The extreme carbon stars , whose derived mass loss rates and optical depths are both very high , are more evolved than infrared carbon stars . these stars are expected to evolve into protoplanatary nebula soon
极端碳星是高度演化后的红外碳星，它的质量损失率及光深都非常高，几乎没有其光学对应体，并将很快演化为前行星状星云。 |
