PTC是一种新型的半导体陶瓷材料，它的发热效率较高，PTC有一个人为设定的温度。当它的温度低于设定温度时，其电阻值会随它的温度升高而变小；当它的温度高于设定温度时，其电阻值随它的温度升高而变大。如图1所示的陶瓷电热水壶就使用了这种材料。它的工作电路如图2所示，R₀是定值电阻，其阻值不受温度的影响。R_T是PTC的电阻，它的电阻值与温度的关系如图3所示。该电热水壶在R_T设定温度状态工作时，电路消耗的总功率1100W。

（1）R₀的阻值为多少?

（2）当R_T的温度为130℃时，电路中R_T的实际功率为多少?

An earthquake happens when two plates rub (碰撞) together. The earth plates travel in different directions and at different speeds. If one plate is slowly forced underneath the other,  pressure builds up until the plates break apart. This process causes the ground to move. It is an earthquake. In other words, earth-quakes are the shaking of the earth’s surface caused by the earth’s rocky outer layer as a result of the energy stored within the earth. The strain within the rocks is suddenly released (释放).

The damage an earthquake causes depends on where it is and the time it is happening. If an unpopulated region is struck, there will be low loss of life or property. If it hits a large city, there may be many in-juries and much destruction. Many of the areas at risk are largely populated now. Major earthquakes hitting those areas today could produce terrible damage.

Actually, there are several million small earth-quakes every year.  Large earthquakes such as the 1964 Alaskan quake that measured 9.2 on the Richter scale, cause millions of dollars in damage. In the last 500 years, millions of people have been killed by earth-quakes around the world — including 240,000 in the 1976 Tangshan earthquake in China.

A 60-second or less earthquake can cause devastation that continues for years after the first tremor (小震). In 1972, a series of severe earthquakes struck Managua, Nicaragua. Fifteen years later, the city still looked the way it had a week after the earthquake hit, because the country did not have the necessary money to rebuild it.

The shaking of the earth is sometimes not the greatest disaster. It is in the ensuing fires and floods that often the greatest damage occurs. In the 1906 earthquake, it was the fires caused after it that did the majority of the damage. An earthquake can also destroy dams high above a city or valleys, causing floods to sweep down and sweep away everything in their path.
