按照经典的电子理论,电子在金属中运动的情形是这样的:在外加电场的作用下,自由电子发生定向运动,便产生了电流。电子在运动的过程中要不断地与金属离子发生碰撞,将动能交给金属离子,而自己的动能降为零,然后在电场的作用下重新开始加速运动(可看作匀加速运动),经加速运动一段距离后,再与金属离子发生碰撞。电子在两次碰撞之间走的平均距离叫自由程,用表示。电子运动的平均速度用表示,导体单位体积内自由电子的数量为n,电子的质量为,电子的电荷量为,电流的表达式I=nes。请证明金属导体的电阻率=

As nanny(保姆), cook, cleaner, shopper, driver, and gardener, she has one of the most demanding jobs in Britain today. And paying someone else to do the chores(家务活) which take the average housewife 71 hours a week would cost €349.

At over €18,000 a year that’s more than the earnings of 70 percent of the population, including train drivers, firemen, prison officers, and social worker. Looking after a baby less than a year old takes a housewife into a even higher pay league. According to a stud, she earns €457 a week – at nearly €24,000 a year, the same as teachers, engineers, and chemists.

Researchers put a price on each chore, then tried to find out how long the average person takes doing them. They found housewives spend an average 70.7 hours a week on housework – with looking after the children (17.9hours) and cooking and cleaning (12.9 hours each) the most time-consuming(费时).

A wife with a part-time job still works and average of 59 hours a week at home. Those in full-time employment put in longer hours at home than in the workplace. The good news is that these hours sharply as children get older. While the average mother with child under one puts in 90 hours weekly, the figure drops to 80 hours from one to four and to 66 hours from five to ten.

Mother-of-four Karen Williams from London said, “Paying the housewives may not be practical, but the government should recognize the value of housework, perhaps through the tax. Running a house takes a lot of time and most husbands don’t understand this. For example, my husband only puts a shelf up now and again. He never cleans the kitchen – that’s the real test.”
