问题 单项选择题

钢结构焊接中,可以引弧的构件是()。

A.主要构件 

B.次要构件 

C.连接板 

D.引弧板 

答案

参考答案:D

解析:这是一道有关施工技术及质量控制的题,主要考核钢结构施工过程中打火引弧的知识点。通过观察四个选项,用排除法能轻易选出正确答案。对于具有一定现场实践经验的考生,此题相对简单。 相关规范规定,钢结构焊接施工过程中,严禁在焊缝区以外的母材上打火引弧。在坡口内起弧的局部面积应焊接一次,不得留下弧坑。 由此可见,只能在结构构件以外单独设置引弧板,故本题的正确项为“D.引弧板”。 考点 建筑工程施工质量管理

The Man of Many Secrets — Harry Houdini — was one of the greatest American entertainers in the theater this century. He was a man famous for his escapes — from prison cells, from wooden boxes floating in rivers, from locked tanks full of water. He appeared in theaters all over Europe and America. Crowds came to see the great Houdini and his “magic” tricks.

Of course, his secret was not magic, or supernatural powers. It was simply strength. He had the ability to move his toes as well as he moved his fingers. He could move his body into almost any position he wanted.

Houdini started working in the entertainment world when he was 17, in 1891. He and his brother Theo performed card tricks in club in New York. They called themselves the Houdini Brothers. When Harry married in 1894, he and his wife Bess worked together as magician and assistant. But for a long time they were not very successful. Then Harry performed his first prison escape, in Chicago in 1898. Harry persuaded a detective to let him try to escape from the prison, and he invited the local newspapermen to watch.

It was the publicity(宣传) that came from this that started Harry Houdini’s success. Harry had fingers trained to escape from handcuffs and toes trained to escape ankle chins. But his biggest secret was how he unlocked the prison doors. Every time he went into the prison cell, Bess gave him a kiss for good luck — and a small skeleton key, which is a key that fits many locks, pass quickly from her mouth to his.

Harry used these prison escapes to build his fame. He arranged to escape from the local prison of every town he visited. In the afternoon, the people of the town would read about it in their local newspapers, and in the evening every seat in the local theater would be full. What was the result? World-wild fame, and a name remembered today.
