relative activity level的意思|示意

To overcome this problem, a novel fusion algorithm is proposed, which is based on a new image region focus measure, Relative Activity Level (RAL), presented in this paper.

该算法定义了图像区域的相对清晰度判定指标，并根据多焦距图像像素邻域的相对清晰度来逐个选取聚焦清晰的像素点从而构成融合图像。

The simulation results showed that under the same coke level, the activity of the coked catalyst depended on the location of the coked sites and the relative coke growth rate.

模拟结果表明，在一定的积炭量下，催化剂的活性主要与积炭的位置及焦炭相对增长速率有关。

Sequences tend to show cyclicity of changes in relative sea level and widespread unconformities, processes of sedimentation and sources of sediments, climate and tectonic activity over time.
