| Terms for subject Environment (7347 entries) |
| barren patch | 芜原地块 | |
| barrier beach (An elongated sand or shingle bank which lies parallel to the coastline and is not submerged by the tide. If it is high enough to permit dune growth it is termed a barrier island) | 沿岸沙滩 | |
| barrier reef (An elongated accumulation of coral lying at low-tide level parallel to the coast but separated from it by a wide and deep lagoon or strait. The coral is thought to have formed initially on a flat surface: then as the sea-level rose in post-glacial times, thereby submerging the irregular wave-cut platform, the coral growth kept pace with the rising ocean level, so creating the great thickness witnessed today in such places as the Great Barrier Reef off the East coast of Queensland, Australia. This stretches for more than 1900 km and varies in width from about 30 km to 150 km) | 堤礁 | |
| base (Any chemical species, ionic or molecular, capable of accepting or receiving a proton (hydrogen ion) from another substance; the other substance acts as an acid in giving of the proton; the other ion is a base; chemical) | 碱 | |
| baseline monitoring (Monitoring of long-term changes in atmospheric compositions of particular significance to the weather and the climate) | 基线检测 | |
| basic food requirement (The minimum nutriments deemed necessary for a person of a particular age, gender, physiological condition and activity level to sustain life, health and growth) | 基本食物需求 | |
| basic metabolic process | 基本代谢过程 | |
| basicity (The state of a solution of containing an excess of hydroxyl ions) | 碱性度 | |
| basidiomycete | 担子菌类 | |
| bastardisation of fauna (One of the possible consequences of the introduction of animal species in an area where they are not indigenous. Such translocation of species always involves an element of risk if not of serious danger. Newly arrived species may be highly competitive with or otherwise adversely affect native species and communities) | 动物种群相劣化 | |
| bastardisation of flora (One of the possible consequences of the introduction of plant species in an area where they are not indigenous) | 植物群相劣化 | |
| batch process (A process that is not in continuous or mass production; operations are carried out with discrete quantities of material or a limited number of items) | 批处理 | |
| batch process | 间歇〔断续〕过程 | |
| batch process | 批量生产〔制法〕 | |
| batch process | 分批〔间歇〕法 | |
| batch process | 周期性过程 | |
| bathing freshwater (Freshwater in which bathing is explicitly authorised or in which bathing is not prohibited and is traditionally practised by a large number of bathers. Water in such areas must meet specified quality standards relating to chemical, microbiological and physical parameters) | 沐浴用淡水 | |
| bathing seawater (Sea waters in which bathing is explicitly authorised or in which bathing is not prohibited and is traditionally practised by a large number of bathers. Water in such areas must meet specified quality standards relating to chemical, microbiological and physical parameters) | 沐浴用海水 | |
| bathing water (All waters, inland or coastal, except those intended for therapeutic purposes or used in swimming pools, an area either in which bathing is explicitly authorised or in which bathing is not prohibited and is traditionally practised by a large number of bathers. Water in such areas must meet specified quality standards relating to chemical, microbiological and physical parameters) | 沐浴用水 | |
| battery (A series of cells, each containing the essentials for producing voltaic electricity, connected together) | 电池 |
