Britain has a naval task force of 27 ships led by the carrier HMS Illustrious on its way to the region to take part in a joint military exercise with Oman. Meanwhile, the US carriers attacked with their aircraft. The Royal Navy's carriers will, at 65,000 tonnes, be smaller, but they are likely to have the same propulsion system. In the long-term, trials are likely with the RN's future carriers HMS Queen Elizabeth and Prince of Wales. The 32 warships of the Royal Navy included five carriers, six cruisers, seven destroyers, and 14 frigates. The major problem facing the Royal Navy is that its carriers are too small. Once he learned of the disaster that had struck his carriers, Admiral Yamamoto, still hundreds of miles to the west with the main battlegroup, reversed course. Princess Margaret paid a call on HMS Illustrious - the carrier she launched 22 years ago. At dawn the next day aircraft from Nagumo's carriers attacked Midway, causing widespread damage. He opened a channel with the USS Carl Vinson, the command carrier of the naval force. In the Second World War carriers replaced battleships as the capital ships of modern navies because aircraft could perform the functions of naval guns more effectively. A Japanese strike force of 188 aircraft launched from four carriers about 350 km Northwest of Darwin over two separate attacks. The Ministry of Defence plans to build two new carriers for the Royal Navy at a cost of about £3.6 billion. The Royal Navy has three carriers equipped with Harrier aircraft but its ageing assault ships have been decommissioned - Fearless only a fortnight ago. The aviation assets required would come from the U.S. Navy's carriers. Aircraft developer Boeing has achieved a major milestone in the flight test programme of the X - 32B Joint Strike Fighter which it hopes to sell to the Royal Navy for its future carriers. At the end of the Battle of Midway, all four Japanese carriers involved in the attack on Pearl Harbor had been sunk, while the United States lost the carrier Yorktown. These weren't frigates, cruisers, carriers or even battleships. Type 22 frigate HMS Cumberland has been lending one of the Royal Navy's carriers a hand during a crucial training period. 2.3 A company that provides facilities for conveying telecommunications messages. 通讯公司 Example sentencesExamples This new company would serve multi-national business customers, international carriers and Internet service providers worldwide. The company's main customers are large businesses and telecommunications carriers. It is now up to cellular carriers and application providers to offer the right products and services to meet this demand. Over 40 international telecoms carriers currently do their billing with the company. In order to make Ethernet successful in metro networks, it indeed needs to evolve to meet requirements of service providers and carriers. Its most valuable customers are those with complex networking needs, and increasingly telecommunication carriers and internet service providers. Telecommunications carriers have to upgrade systems and equipment for state-of-the-art digital services. The dominant players in telecom outsourcing are long-distance carriers like AT&T, WorldCom and Sprint. The major telecom carriers all see wireless data as an important growth market, and they plan to package voice and data services into a one-stop-shop offering. The carriers have heard the message and are attempting to move in that direction. Nortel Networks has secured optical infrastructure contracts with three China Telecom regional carriers. Seven sells software to telecom carriers who manage wireless networks for corporate clients. In international trade, however, the lowest-cost carrier who provides acceptable service normally prevails. Phone companies and telecommunications carriers have been up on the block since British Telecom was sold almost two decades ago. While the large telecom carriers may have been slow to answer the call, they are certainly listening now. In the meantime, what are the winning strategies for telecom carriers? Both carriers are using fixed wireless to provide a bundle of services to business customers in the 40 to 60 markets where they also offer fiber connections. Since the government began to privatise the telecommunications carrier, basic telephone charges have increased by 160 to 220 percent. To meet these needs, a new category of system is now being deployed by carriers and service providers around the world. Courts are auctioning off equipment that belonged to bankrupt carriers and Internet service providers for 10 cents on the dollar. 3A person or animal that transmits a disease-causing organism to others. Typically, the carrier suffers no symptoms of the disease. 带菌者，病邮 the black rat, best known as carrier of bubonic plague Example sentencesExamples Rabies is most frequently transmitted to people by dogs, and so is most feared where dog populations are densest, although rural dogs and various wild animals are also carriers. It is known, however, that smallpox cannot be spread by an animal carrier, and therefore that method of transmission does not need to be considered. When the carrier insect feeds on a warm-blooded animal, the eggs hatch and the larva penetrates the skin. The problem with existing vaccines is that vaccinated animals can be carriers of the disease even though they do not show any symptoms. Approximately two-thirds of these people with chronic infection do not themselves get sick or die of the virus, but they are carriers and can transmit it to other people. If you see any mice, rodents or other potential carriers of those dangerous fleas, kill them immediately. Roughly 5 percent of those who contract the illness become chronic carriers - excreting the typhoid bacteria in their stools for more than a year. For instance, rabies can be controlled by avoiding rabid or any stray dogs coming into contact with sheep, as the dogs that may be carriers of the disease may bite them, and transmit the disease. Some infected but asymptomatic patients may be carriers. They cause dairy and deer farmers anxiety as they are carriers of bovine tuberculosis. Tsetse flies are carriers of trypanosomes - the parasites transmitted by their bites, which cause sleeping sickness in men and cattle. One solution commonly proposed to address disease outbreaks is to eliminate entire populations of the carrier animals. Sufferers of leprosy and tuberculosis as well as carriers of the germs responsible for those diseases are particularly at risk of this false positive reaction. It is an old enemy, the lethal form of a familiar virus, and a threat that has recurred down the centuries with animals the carriers, as the plague was spread by rats. Asymptomatic carriers can introduce the organism into new populations. Two of the carriers were a cardiothoracic surgeon and a perfusionist. The farmers were asking for government subsidies for the losses they have suffered due to fears that the animals are potential carriers of the virus. The dog is the important carrier or reservoir of rabies. These carrier animals could cause a new outbreak. The animal has been portrayed as a good sheep dog, a carrier of the needed aid, a messenger in the time of war, a seeing eye to the physically impaired, of simply a trusty household pet. 3.1 A person or other organism that possesses a particular gene, especially as a single copy whose effect is masked by a dominant allele, so that the associated characteristic (such as a hereditary disease) is not displayed but may be passed to offspring. 带隐性基因者 Example sentencesExamples If no disease is present then the gene is recessive; the person is a carrier, but may pass on the defective gene to the offspring. And there is a 25% chance that the baby will be completely free of the gene - not a carrier and not have the disease. According to the organisation, one in every 40 people is a genetic carrier of the disease and one in 6,000 babies is born with the disease. Between one and three percent of the Amish people of Lancaster County Pennsylvania are believed to be unaffected carriers of the disease, having just one copy of the altered gene. There is a two-in-four chance that the child will inherit one of each kind of gene and be a carrier like the parents and free of disease. Counseling regarding the trait is important because the hemoglobin gene can be passed on to a carrier's child. If they inherited one good copy and one mutant copy they would be carriers of the disease, while remaining healthy themselves. Premature ovarian failure occurs in up to 20 percent of women who are premutation carriers of the FMR1 gene. A male can't pass the gene for hemophilia to his sons, though all his daughters will be carriers of the disease gene. Kennedy's Syndrome occurs only in males, although 50% of female offspring are carriers. If they have one copy of the gene they are carriers. A child can only have Tay-Sachs disease if both parents are carriers of the gene. Daughters cannot inherit the disease in this way but can become carriers and pass it down to their sons. People with one normal gene and one sickle gene are carriers of the abnormal gene. In the 1980s, there was no test to identify a carrier of the recessive gene for Canavan disease and no test to identify a fetus with the disease. There is a 50% chance with each pregnancy that a carrier female will pass on the abnormal recessive gene. Counseling and education regarding the trait are important because the sickle gene can be passed to a carrier's children. Because women have two X chromosomes, one defective gene is not sufficient to cause the disease; instead women serve as carriers, passing the bad gene to sons. An unaffected carrier male will pass on the pre-mutation to all of his daughters but to none of his sons. Genetic tests can also be used to establish a diagnosis or identify gene carriers prior to the onset of symptoms. 4A substance used to support or convey another substance such as a pigment, catalyst, or radioactive material. （色素、催化剂或放射物质的）载体 Example sentencesExamples This radioactive source constantly gives off high-energy electrons, which collide with the sample molecules and the carrier gas to form ions. A film is printed onto a carrier of polyvinyl alcohol. Quinine and caffeine are two distinguished carriers of such alkaloids. The administration of ‘blood, red blood cells, artificial oxygen carriers and related blood products’ is banned. ‘Methanol is still a good carrier of hydrogen for fuel cell use,’ Browning says. The production of salves, creams and lotions will require some or all of the following which are used as the carriers for the active substances. Paints are made up of four components: pigment, binder, solvent/liquid carrier and additives. Ethanol functions as a carrier for the perfume oils. Herbicides can be applied in combination, using either water or liquid fertilizer as a carrier, to decrease trips over the field. An essential part of some carrier substances are the fixed oils and waxes. In the form of iodized salt, it is a carrier of iodine. Argon is also an ideal carrier gas, a propellant with no propensity to react. Use caution when using a nitrogen fertilizer as the carrier in mixtures. Case Slick uses an alcohol carrier that evaporates and leaves just a little lube on the case. This simultaneously reduces the number of free carriers in the material. Flux injection is a relatively new process in which fluxing compounds are introduced into the molten metal by a mechanical device using an inert gas carrier. Castor oil is also a source of glycerine, and the combination of glycerine and hydroxy fatty acids makes it an excellent emollient and pigment carrier. 4.1Physics short for charge carrier 4.2Biochemistry A molecule that transfers a specified molecule or ion within the body, especially across a cell membrane. 〔生化〕载体 Example sentencesExamples The plasma membrane is the first biological barrier encountered by the ODN carriers on their way into the cell cytoplasm. Today we recognise that viruses are gene carriers just as lipoproteins are the cholesterol/fatty acid carriers of the body's circulatory system. This protein, a carrier of small hydrophobic molecules including retinoic acid, has the potential to modulate lymphatic responses. Like insulin, glucagon lacks a plasma carrier protein, and like insulin its circulating half life is also about 5 minutes. The transcellular pathway involves the movement of ions across the cytoplasm via plasma membrane channels, carriers, and exchangers.
