酚二磺酸分光光度法测定水中硝酸盐氮时，在水样蒸干后，加入酚二磺酸试剂，充分研磨使硝化

A girl complained to her father about her hard life．She didn't know what she had to do and wanted to give up．She felt tired of fighting and fighting．One problem had been finished but another came over．

Her father，a cook，took her into the kitchen．He poured water into three pans and boiled(煮沸) them．After boiling，in the first pan was put some carrots，the second was put some eggs and the last was put with coffee．

The girl waited impatiently (不耐烦的)，confused by what her father did．About 20 minutes later，her father took out the carrots and put them in a bowl．He took the eggs and put them in a bowl．After that the coffee was poured into a cup．“My sweet heart，what do you see？” he asked．

“Carrots，eggs and coffee，” she replied．

Her father told her to close her eyes and asked her to touch the carrots．She did so and felt that the carrots were soft．After that he asked her to take the eggs and break them．After peeling (剥开) them，she got the eggs，cooked and hard．The last，the father let her smell the coffee． She asked，“What did you do this for，Father？” He explained that each had the same unlucky experience—the boiling water，but each had a different result． The strong and hard carrots had become soft and weak．The fragile eggs became hard after being cooked． The coffee was very special，they could change water．“Who are you？” asked her father．“When bad luck knocks at your door，what is your decision? Are you carrots，eggs or coffee？”
