     Today people can use the phone to talk with others almost anywhere on earth. But when you use the

phone, you don't see the person you are talking with. This may change in the near future.

     Today some people are using a kind of telephone called the picture phone or vision phone. With it, two

people who are talking can see each other.

     Picture phones can be useful when you have something to show to the person you're calling. They may

have other uses in the future. One day you may be able to ring up a library and ask to see a book. Then you'll

be able to read the book right over your picture phone. Or you may be able to go shopping through your

picture phone. If you see something in the newspaper that you think you want to buy, you'll go to your phone

and call the shop. People at the shop will show you the thing you're interested in right over the phone. You'll be

able to shop all over town and never even leave your room!

发展休闲经济存在的问题及对策有哪些？

《木结构设计规范》GB50005-2003的4．1．7条，规定了结构重要性系数γ₀的取值，γ₀与设计使用年限有关。表4．2．1-5规定了对应于设计使用年限的强度调整系数。我发现，两者是互为倒数的，例如，设计使用年限为25年，γ₀取0．95，1／0．95=1．05，恰好为设计使用年限25年时的强度调整系数。由于设计时要求γ₀S≤R，规范在这个地方是不是重复计算了？
