| 生物燃料 |
biofuel (A gaseous, liquid, or solid fuel that contains an energy content derived from a biological source. The organic matter that makes up living organisms provides a potential source of trapped energy that is beginning to be exploited to supply the ever-increasing energy demand around the world. An example of a biofuel is rapeseed oil, which can be used in place of diesel fuel in modified engines. The methyl ester of this oil, rapeseed methyl ester (RME), can be used in unmodified diesel engines and is sometimes known as biodiesel. Other biofuels include biogas and gasohol) |
|
| 生物蓄积性污染物 |
bioaccumulative pollutant (Pollutants that become concentrated in living organisms through the consumption of food or water) |
|
| 生物过程 |
biological process (Processes concerning living organisms) |
|
| 生物过滤 |
biofiltration (The distribution of settled sewage on a bed of inert granular material through which it is allowed to percolate. In doing so, the effluent is aerated thus allowing aerobic bacteria and fungi to reduce its biochemical oxygen demand) |
|
| 生物富集系数 |
bioconcentration factor (The quotient of the concentration of a chemical in aquatic organisms at a specific time or during a discrete time period of exposure, divided by the concentration in the surrounding water at the same time or during the same period) |
|
| 生物反应器 |
bioreactor (A container, such as a large fermentation chamber, for growing living organisms that are used in the industrial production of substances such as pharmaceuticals, antibodies, or vaccines) |
|
| 生物量 |
biomass (Biomass refers strictly speaking to the total weight of all the living things in an ecosystem. However, it has come to refer to the amount of plant and crop material that could be produced in an ecosystem for making biofuels and other raw materials used in industry, for example) |
|
| 生物发光 |
bioluminescence (The production of light of various colors by living organisms (e.g. some bacteria and fungi, glow-worms and many marine animals). Luminescence is produced by a biochemical reaction, which is catalyzed by an enzyme. In some animals the light is used as a mating signal; in others it may be a protective device. In deep-sea forms luminous organs may serve as lanterns) |
|
| 生物发展 |
biological development (The action of growing of living organisms) |
|
| 生物监测 |
biological monitoring (The direct measurement of changes in the biological status of a habitat, based on evaluations of the number and distribution of individuals or species before and after a change) |
|
| 生物保护区 |
biological reserve (An area of land and/or of water designated as having protected status for purposes of preserving certain biological features. Reserves are managed primarily to safeguard these features and provide opportunities for research into the problems underlying the management of natural sites and of vegetation and animal populations. Regulations are normally imposed controlling public access and disturbance) |
|
| 生物因素 |
biotic factor (The influence upon the environment of organisms owing to the presence and activities of other organisms, as distinct from a physical, abiotic, environmental factor) |
|
| 生物工程 |
biological engineering (The application of engineering principles and techniques to living organisms. It is largely concerned with the design of replacement body parts, such as limbs, heart valves, etc.) |
|
| 生物固氮 |
biological nitrogen fixation |
|
| 生命大爆炸 |
life explosion |
|
| 生命质量 |
quality of life (Quality of life is largely a matter of individual preference and perception and overlaps the concept of social well-being. Generally the emphasis is on the amount and distribution of jointly consumed public goods, such as health care and welfare services, protection against crime, regulation of pollution, preservation of fine landscapes and historic townscapes) |
|
| 生命周期 |
life cycle (The phases, changes, or stages through which an organism passes throughout its lifetime) |
|
| 生命力 |
life force |
|
| 生命力 |
vitality |
|
| 生命科学 |
life science (A science based on living organisms collectively) |
