对继电保护装置的基本要求是：可靠性、选择性、快速性和灵敏性。

The internet has led to huge increase in credit-card (信用卡) fraud. Your card information could even be for sale in an illegal Website (非法网站). Websites offering cheap goods and services should be regarded with card. On line, shoppers who enter their credit-card information may never receive the goods they thought they bought.

The thieves then go shopping with your card number or sell the information over the Internet.

Computer hackers have broken down security (安全) system, raising questions about the safety of card-holder information.

Several months ago, 25000 customers of CD universe, an on-line music retailer, were not lucky. Their names, addresses and credit-card numbers were posted on a Website after the retailer refused to pay USD 157 828 to get back the information.

Credit-card firms are now fighting against on-line fraud. Master-card is working on plans for Web-only credit-card, with a lower credit limit. The card could be used only for shopping on-line. However, there are a few simple steps you can take to keep from being cheated.

Ask about your credit-card firm’s on-line rules: Under British law, cardholders are responsible for the first USD 78 of any fraudulent spending.

And shop only at secure sites: Send your credit-card information only if the Website offers advanced secure system.

If the security is in place, a letter will appear in the bottom right-hand corner of your screen. The Website address may also start the extra “s” stands for secure. If in doubt, give your credit-card information over the telephone.

Keep your password (密码) safe: Most on-line sites require a user name and password before placing an order. Treat your password with care.
