| 一次性包装 | non-returnable container (Any container for which no specific provisions for its return from the consumer or final use has been established) | |
| 一氧化氮 | nitrogen oxide (A colorless gas that, at room temperature, reacts with oxygen to form nitrogen dioxide; may be used to form other compounds, NOx) | |
| 一氧化二氮 | nitrogen monoxide (A colourless gas, soluble in water, ethanol and ether. It is formed in many reactions involving the reduction of nitric acid, but more convenient reactions for the preparation of reasonably pure NO are reactions of sodium nitrite, sulphuric acid, etc.) | |
| 一氧化碳 | carbon monoxide (Colorless, odourless, tasteless, non-corrosive, highly poisonous gas of about the same density as that of air. Very flammable, burning in air with bright blue flame. Although each molecule of CO has one carbon atom and one oxygen atom, it has a shape similar to that of an oxygen molecule (two atoms of oxygen), which is important with regard to it's lethality, CO) | |
| 一氧化碳污染试验 | carbon monoxide pollution experiment | |
| 一般行政秩序 | general administrative order (An administrative mandate outlining the process by which a concept, plan, decree or law is to be put into actual practice by a specific organization or government agency) | |
| 刀耕火种文化 | slash and burn culture (A traditional farming system that has been used by generations of farmers in tropical forests and the savannah of north and east Africa. It is known to be an ecologically sound form of cultivation, and because the soil is poor in tropical rain forests it is a sustainable method of farming. It is still practised today, primarily in the developing countries. Small areas of bush or forests are cleared and the smaller trees burned. This unlocks the nutrients in the vegetation and gives the soil fertilizer that is easily taken up by plants. A few years later the soil is degraded and the farmer moves on to do the same at another site. The original ground is left fallow for anything up to 20 years so that the forest can regenerate. With the growth in population and in the subsequent need for more farming land to produce food, the method is increasingly being used today to clear large areas of tropical forests for cattle ranching, and in most cases the ground is not left fallow for long enough and, with modern mechanized farming systems, not enough tree stumps or suitable habitats for plant life are left to start the regeneration process) | |
| 开阔生境 | open habitat | |
| 开渠 | channelling (Any system of distribution canals or conduits for water, gas, electricity, or steam) | |
| 开放草坪 | open lawn (Any relatively unobstructed field of cultivated and mown grass, especially near a house or in a park) | |
| 开垦荒地 | land reclamation | |
| 开花植物 | flowering plant (Plants capable of producing conspicuous flowers) | |
| 开发合作 | development co-operation | |
| 开发地下水 | exploitation of underground water (The process of extracting underground water from a source) | |
| 开发区 | development area (Area which has been given special help from a government to encourage business and factories to be set up there) | |
| 开矿之后的地形 | landscape after mining (The process of mining disfigures the surface of the land, and in the absence of reclamation leads to permanent scars. The process spoils the vital topsoil, disrupts drainage patterns, destroys the productive capacity of agricultural and forest land and impairs their aesthetic and social value) | |

| Wyoming Oil and Gas Conservation Committee | ||
| 攀援植物 | climbing plant (A plant that lacks rigidity and grows upwards by twining, scrambling, or clinging with tendrils and suckers; wall) | |
| 最小成本加最低损失防火理论 | economic fire protection theory |
