medium intensity light

Spatial distribution of water erosion was divided into two areas: north hilly area of medium erosion intensity and central district of light erosion intensity.

并将库区水力侵蚀空间分布划分为北部中低山丘陵中强度侵蚀区和中部河谷城区轻度流失区。

Based on the above-mentioned sub-district, a district generally need a master can lighting, this should be the main lights set within the wall, light intensity of appropriate medium.

基于上面说到的分区，一个区一般只需要一台主照明灯即可，这台主照明灯应是镶在墙体之内的，光亮强度中等为宜。

T he training program might include light, medium and heavy phases that vary the workload a light phase means a low workload of mostly lower intensity training like jogging, drills and light weights.

这些项目包括轻度、中度和高强度三种。经度训练指强度相对较低的训练，如：慢跑、练习、轻量训练。
