Auto identification of rolling layers in roller-compacted concrete dam

A scheme for identifying rolling layers in roller-compacted concrete (RCC) dam automatically was presented. First, a conceptual model was developed. Second, by using a computational geometry method, the auto identification of rolling layers and auto matching between rolling compaction machines and rolling layers were realized based on spatial control points. An application to the construction of Guandi RCC dam showed that the auto identification of rolling layers played an important role in ensuring the engineering quality.     

深圳华科瑞HW2096型酶标洗板机故障检修3例

洗板机是专门清洗酶标板的,一般和酶标仪配套使用。它的应用领域广泛,已在医院、血站、卫生防疫站、试剂厂、研究室的酶标板清洗配套使用。深圳华科瑞HW2096型酶标洗板机能自动完成各种酶标板的清洗工作,采用超大流量和极高的真空度,保证洗板的残留液控制在1ul以内;合理性的开关机蒸馏水自动冲洗程序和堵孔报警系统,可以有效的避免因堵孔而造成的花板、假阳性现象。以下主要介绍华科瑞HW2096型酶标洗板机在日常工作中出现的故障以及分析和排除情况。
