有二组六块芯样经加工后的试件尺寸分别列下表，请计算这六块芯样试件尺寸偏差是否可用作抗压强度试验，为什么？
参考答案：
为了避免对芯样高径比进行修正，按《规范》要求，芯样试件高度小于0.95d或大于1.05d（d为芯样试件平均直径），不得作为抗压强度试验。经计算：
一组：第1块 试验高度为0.99d 可作为抗压强度试验
第2块 试验高度为1.06d 不得作为抗压强度试验
第3块 试验高度为0.99d 可作为抗压强度试验
二组：第1块 试验高度为1.04d 可作为抗压强度试验
第2块 试验高度为0.93d 不得作为抗压强度试验
第3块 试验高度为0.97d 可作为抗压强度试验
| A few years ago, my friend Al won the lottery ( * * ), which changed his life. He was not born with a silver spoon in his mouth. 1 , my friend was always hard up for cash. He did not have much money. And the money he did earn was chicken feed - very 2 . Sometimes Al even had to 3 some gifts from his family and friends. He was not the kind of person who never paid the money he 4 .He was always very careful with the money he spent. The 5 times were when he was flat broke and had no money at all. One day, Al scraped together a few dollars for a 6 ticket. He thought he would never gain lots of money 7 . But his combination of numbers was chosen and he 8 the lottery. That is to say, he won a great deal of 9 . Al was so 10 . The first thing he did was to buy a new car. He showed off the one thing that he normally would not buy. Then he started spending money on 11 things. It was like he had money to 12 . He had more money than he needed and it was burning a hole in his pocket so he spent it quickly. When we 13 for a meal at a restaurant, Al paid every time. He would always pay bills for others. He told me the money made him feel like a millionaire 14 he felt very happy. But shortly after that my friend was 15 and out again. He had no money left. He had 16 his bottom dollar, his very last amount. I admit I do feel 17 for my friend. He had enough money to live like a king. Instead, he is 18 to living on a shoestring - a very low budget. Some might say he is penny 19 and pound foolish. He was wise about small things, but 20 about important things. | ||||
