问题 问答题

某化工厂仓储区有甲醇罐和乙烯罐各1个,两罐相距150m,储量分别为15t和6t。 问题:该仓储区是否构成特大危险源(储存区甲醇的临界量是20t,贮存区乙烯的临界量是10t)。

答案

参考答案:

解析:按照国家标准《重大危险源辨识》,对于单元内存在危险物品是多种时,以是否满足以下公式来确定是否构成重大危险源:qi/Qi≥1,则15/20+6/10=1.35>1,所以该仓库储区构成重大危险源。

阅读短文,根据要求完成下面各小题。

Michael went back to Fullerton, his home town. His visit to Fullerton was very special to him. He was born there, he grew up there. But he hadn’t been back there since he finished high school.

He went to places he hadn’t gone to in years. He walked through the park and remembered the days he had walked through that same park with his friend. He passed by the field where he and his friends had played baseball every day after school. And he stood in front of the movie theater and thought about all the Saturday afternoons he had spent there, watching his favorite movie heroes and eating popcorn.

He did things he hadn’t done in a long time. He had some home-made ice cream at the ice cream shop. He rode on the merry-go-round in the park, and he went fishing at the lake. For a little while, he felt like a kid again.

He saw people he hadn’t seen in years. He visited several of his old neighbors. He said hello to the owners of the candy store near his house. And he also went to see Mrs. Riley, his tenth-grade science teacher.

Michael’s trip back to Fullerton was a very nostalgic (怀旧的) experience for him. Going back to Fullerton brought back many memories of days gone by.
