| 病毒 |
virus (Submicroscopic agents that infect plants, animals and bacteria, and are unable to reproduce outside the tissues of the host. A fully formed virus consists of nucleic acid (DNA or RNA) surrounded by a protein and lipid (fat) coat. The nucleic acid of the virus interferes with nucleic acid-synthesizing mechanism of the host cell, organizing it to produce more viral nucleic acid. Viruses cause many diseases (e.g., mosaic diseases of many cultivated plants, myxomatosis, foot and mouth disease, the common cold, influenza, measles, poliomyelitis). Many plant viruses are transmitted by insects, some by eelworms. Animal viruses are spread by contact, droplet infection or by insect vectors and some are spread by the exchange of body fluids) |

| 装备最优化 |
installation optimisation (Adjustments made to a building or to a mechanical or electrical system or apparatus in order to maximize its functionality and efficiency) |
|
| 装备需求认可 |

| 铅 |
lead (A heavy toxic bluish-white metallic element that is highly malleable; occurs principally as galena and is used in alloys, accumulators, cable sheaths, paints, and as a radiation shield, Pb) |
|
| 铅化合物 |
lead compound (Lead compounds are present as gasoline additives, in paint, ceramic products, roofing, caulking, electrical applications, tubes, or containers. Lead exposure may be due to air, water, food, or soil. Lead in the air is primarily due to lead-based fuels and the combustion of solid waste, coal, oils, and emissions from alkyl lead manufacturers, wind blown dust volcanoes, the burning of lead-painted surfaces, and cigarette smoke. Lead in drinking water comes from leaching from lead pipes, connectors, and solder in both the distribution system and household plumbing) |

| 铅污染 |
lead contamination (The presence and release into the air, water and soil, of lead, a toxic metal used in plumbing, gasoline and lead-acid batteries) |
|
| 准备市场 |
preparation for market (The containment, protection, handling and presentation of goods for the market) |
|
| 密封 |
encapsulation (The enclosure of any polluting product with a material that prevents its release in the environment) |
