| Terms for subject Environment (7358 entries) |
| 残油 | residual products | |
| 残油回收 | oil residue recuperation (The recovery of oil that is leftover or left behind, usually following the primary containment operations for an oil spill) | |
| 趋势 | trend (The general drift, tendency, or bent of a set of statistical data as related to time or another related set of statistical data) | |
| 二次处理 | secondary treatment (Stage of the process of waste water treatment: following primary treatment by sedimentation, the second step in most wastewater systems in which biological organisms decompose most of the organic matter into a innocuous, stable form) | |
| 二次燃烧 | afterburning (An afterburner is a gadget fitted to the exhaust flues of furnaces and also to the exhaust systems of motor vehicles. They remove polluting gases and particles, which are the result of incompletely combusted fuel, by incineration and break down other chemical molecules associated with combustion into inert chemicals) | |
| 二氧化氮 | nitrogen dioxide (A reddish-brown gas; it exists in varying degrees of concentration in equilibrium with other nitrogen oxides; used to produce nitric acid, NO2) | |
| 二氧化硫 | sulphur dioxide (Emissions of the gas given off during the burning of fossil fuels in power stations and other boilers. Sulphur dioxide is created because sulphur is an impurity in most coal and oils. When the fuel is burned the hot sulphur reacts with oxygen in the atmosphere to form sulphur dioxide, SO2) | |
| 二氧化硫胁迫 | SO₂stress | |
| 二氧化硫胁迫 | sulfur dioxide stress | |
| 二氧化钛 | titanium dioxide (A white, water-insoluble powder that melts at 1560°C, and which is produced commercially from the titanium dioxide minerals ilmenite and rutile; used in paints and cosmetics) | |
| 二氧化碳 | carbon dioxide (A colourless gas with a faint tingling smell and taste. Atmospheric carbon dioxide is the source of carbon for plants. As carbon dioxide is heavier than air and does not support combustion, it is used in fire extinguishers. It is a normal constituent of the atmosphere, relatively innocuous in itself but playing an important role in the greenhouse effect. It is produced during the combustion of fossil fuels when the carbon content of the fuels reacts with the oxygen during combustion. It is also produced when living organisms respire. It is essential for plant nutrition and in the ocean phytoplankton is capable of absorbing and releasing large quantities of the gas, CO2) | |
| 二氧化碳同化的三碳途径 | C3 pathway of CO2 assimilation | |
| 二氧化碳税 | carbon dioxide tax (Compulsory charges levied on fuels to reduce the output of carbon dioxide (CO2), which is a colourless and odourless gas substance that is incombustible) | |
| 二氧化碳固定 | carbon fixation | |
| 二氧化碳固定 | carbon capture | |
| 二氧化碳固定 | carbon dioxide fixation | |
| 二元经济 | dual economy (An economy based upon two separate/distinct economic systems which co-exist in the same geographical space. Dualism is characteristic of many developing countries in which some parts of a country resemble advanced economies while other parts resemble traditional economies, i.e. there are circuits of production and exchange) | |
| 二手商品 | second-hand goods (Goods or products that have been used previously) | |
| 二恶英 | polychlordibenzo-p-dioxin (PCDD are formed (along with variants including furans) when compounds containing chlorine are burnt at low temperature in improperly operated/designed domestic refuse and industrial waste incinerators where PCDDs can be found in both the flue gases and the fly ash) | |
| 二级变水 ［类］ | secondarily poikilohydric form |
