不影响肺内气体交换的因素是

A.气体的扩散系数

B.肺活量

C.呼吸膜的面积

D.通气/血流比值

答案

参考答案:B

解析:气体的扩散系数可影响气体在肺内的扩散速率。呼吸膜的面积和通气/血流比值是影响肺换气的因素。肺活量是反映肺功能的常用指标,与肺内气体交换无关。

Following the nuclear at the Fukushima (福岛) nuclear power station in Japan, Germany has decided to abandon the use of nuclear energy sooner than it had planned.

Germany was planning to cut its use of nuclear power slowly over 25 years. But now, the government has speeded up its program. Germany’s government has said that seven of its 17 nuclear reactors (反应堆) will stop working for three months for safety checks.

Nuclear power has been very unpopular in Germany since the Chernobyl (切尔诺贝利) nuclear reactor disaster in Ukraine (乌克兰) in 1986. Since then, the country has been working on developing new resources of energy.

The plan to give up nuclear power will cost the country at least 150 billion euros (1.4 trillion yuan)) in investment. Experts say this will likely lead to a rise in electricity prices.

Some experts think Germany is setting a good example for countries such as the US to follow. Germany now gets 23 percent of its energy from nuclear power –about as much as the US.

However, France, which relies on nuclear energy for more than 70 percent of its power, shows no sign of changing its policy.

A.In both the US and Germany, approximately a quarter of their energy are from nuclear power now.

B.The explosion of some Fukushima nuclear reactors has quickened Germany’s pace to abandon nuclear energy.

C.France, which relies on nuclear energy for more than 70 percent of its power, will follow Germany and cut its use of it at any cost.

D.The Chernobyl nuclear disaster seemingly cast a huge shadow over the Germans, making them increasingly suspicious of the safety of nuclear energy.
