$\alpha$放射性粉塵の粒子径測定方法のひとつとしてオートラジオグラフ法がある。この方法を日常の放射線管理により使い易いものにするため、1978年に曝射用カメラと蛍光膜を組み合わせたオートラジオグラフ装置(以下「ARG」という)が製作され、その装置を用いて粒子径測定方法が確立された。筆者らは、この粒子径測定方法での、ARG写真からのスポット像の読み取り及びデータ処理に、多大の労力と時間を費やしていることに着目し、読み取り装置とデータ処理を含くむシステムの自動化の検討と試作機(以下「画像解析装置 ...

Shuitu Baochi Xuebao[目的] 为明晰降雨能量和初始含水率对土壤团聚体溅蚀过程机制的影响。[方法] 选取东北典型耕层黑土为研究对象,通过人工模拟降雨试验,探讨不同初始含水率、降雨能量和团聚体初始粒径的团粒溅蚀特征。[结果] (1)4种初始粒径黑土团聚体的溅蚀量均在初始含水率4%时最大,其中初始粒径＜0.25 mm团聚体溅蚀量是相同降雨能量下各粒径团聚体溅蚀量的1.21~5.50倍。随初始含水率的增加各初始粒级团聚体溅蚀量呈减小趋势,而初始含水率＞25%后则呈增大现象。(2 ...
