轨道电路

轨道电路由钢轨线路和钢轨绝缘构成的电路,用于自动、连续检测这段线路是否被机车车辆占用,也用于控制信号装置或转辙装置,以保证行车安全的设备。 整个轨道系统路网依适当距离区分成许多闭塞区间,各闭塞区间以轨道绝缘接头区隔,形成一独立轨道电路,各区间的起始点皆设有信号机(色灯式信号机),当列车进入闭塞区间后,轨道电路立即反应,并传达本区间已有列车通行,禁止其他列车进入的讯息至信号机,此时位于区间入口的信号机,立即显示险阻禁行的信息。

Directions:In this part, there is one passage followed by a summary. Read the passage carefully and complete the summary with the appropriate words from the passage. Remember to write the answers on the Answer Sheet.  Questions 1-5 are based on the following passage.  Wine can be made with red grapes or white grapes, and, especially in the case of red wines, a number of medical researchers have reported that a moderate amount of wine has certain health benefits. This may be one of the reasons why the number of people drinking wine has risen over the past years. As new wine shoppers browse the shelves of their local markets, they face a tough decision. Should they buy a wine with a cork or a screw top? And shoppers are not alone in their dilemma. Wineries are also facing tough choices in the best way to seal their products.  The root of the problem lies in “cork taint.” Cork taint refers to a problem with wine that has been sealed with a bad cork. Traditionally, all corks are made from a special oak tree that grows around the Mediterranean. In the process of making the corks and sealing wine bottles, a certain type of mold may start to grow on some corks. Over time, this mold can produce a chemical that makes the wine inside the bottle taste musty. In fact, the human tongue is so sensitive to this particular compound that people can taste it even diluted up to six parts per trillion!  How big is the problem of cork taint? Some experts from the wine industry claim cork taint affects one out of every ten bottles of wine. And as one spokesperson for an American winery says, “No other packaging industry in the world would put up with that kind of failure rate.”  Some wine makers see a possible solution to the problem of cork taint through adopting the tried and true method of sealing bottles with screw tops. However, many wineries are still playing it safe and sticking to corks for two reasons. First, there is the old belief among cork users that small amounts of oxygen are able to penetrate corks. This oxygen, they say, is necessary for the proper aging of fine wines, especially those aged 10 years or more. Screw tops do not allow for any oxygen to get into the bottles after they are sealed.  Another problem arises from the image screw tops have with the public. In most people’s minds, screw tops are only found on cheap, low-quality wines. It will take a lot of effort from wineries to re-educate the public if they want to change the image of screw tops. In addition, there is the problem of losing the romantic, elegant mood produced by the ceremonial popping of the cork. Consumers don’t seem to feel the same thrill when unscrewing a top.  Summary:  The wine industry is facing a dilemma. What is the best way to  1 wine bottles? Many people think that it is only  2 for wine bottles to be sealed with corks. They think that oxygen needs to be able to penetrate the cork. Other experts, however, suggest that wineries change to  3 . Using corks can lead to cork taint, a bad taste in the wine caused by  4 .
