| 不溶解性物质 | insoluble substance Substance incapable of forming a solution, especially in water (不能溶于溶液的物质，特别是指不溶于水。) |
| 可溶性 | solubility The ability of a substance to form a solution with another substance (一种物质与其他物质形成溶解的能力。) |
| 岩溶 | karst 1. A German rendering of a Serbo-Croat term referring to the terrain created by limestone solution and characterized by a virtual absence of surface drainage, a series of surface hollows, depressions and fissures, collapse structures, and an extensive subterranean drainage network. 2. A type of topography that is formed on limestone, gypsum, and other rocks by dissolution, and that is characterized by sinkholes, caves, and underground drainage. Etymology: German, from the Yugoslavian territory Krs; type locality, a limestone plateau in the Dinaric Alps of northwestern Yugoslavia and northeastern Italy (一个德国地域风味的塞尔维亚克罗地亚用语，指由石灰岩溶解创造的一种地形，其以假设的不存在地表排水系统、有一系列的表面凹地、凹陷和裂缝、崩塌结构以及遍布的地下排水系统为标志。 一种地貌，由石灰岩、石膏和其它岩石的溶解形成，以溶洞、洞穴和地下排水为标志。词源：德语，来自南斯拉夫领土krs；此类型地区在南斯拉夫的西北部和意大利东北部的迪纳拉造山带阿尔卑斯山的石灰岩高原。) |
| 总溶解固形物 | total dissolved solid |
| 有机溶剂 | organic solvent Organic materials, including diluents and thinners, which are liquids at standard conditions and which are used as dissolvers, viscosity reducers, or cleaning agents (有机材料，包括稀释剂和冲淡剂，它在标准条件是液体并被用作溶解装置、粘度还原剂或清洗剂。) |
| 核溶解 | core meltdown An accidental overheating of the part of the nuclear reactor where fission takes place, causing fuel elements and other parts of the reactor to melt, potentially leading to catastrophic consequences in which dangerous levels of radioactive materials would be released into the environment (部分产生原子分裂的核能反应器意外过热，造成燃料元素和其他部分反应器熔解，可能造成危险性放射物质溢散至环境中的灾难性后果。) |
| 溶剂 | solvent Substance, generally a liquid, capable of dissolving another substance (通常是可溶解另一种物质的液体物质。) |
| 溶剂回收 | solvent recovery Solvent recovery is a widely practised form of recycling where spent solvents are distilled and reused. However, the cheaper solvents are often incinerated or dumped in hazardous waste landfill sites (溶剂回收是蒸馏或再生溶剂的广泛采用的形式。然而，更便宜的溶剂通常是在危险废物焚烧或丢弃的堆积区。) |
| 溶媒回收 | solvent recovery |
| 溶度值, 溶液中与溶剂和总溶液的量成正比的溶质质量、体积、或摩尔数。 | concentration In solutions, the mass, volume, or number of moles of solute present in proportion to the amount of solvent or total solution; value |
| 溶性粒子 | dissolved particle |
| 溶液培养、水生栽培 | hydroculture Growing plants without soil but in sand or vermiculite or other granular material, using a liquid solution of nutrients to feed them (使植物在沙、蛭石或其它细小颗粒物等非土壤环境中生长，用液体营养液为其提供养分。) |
| 溶 融解 | diffluence |
| 溶解 | dissolution Dissolving of a material (物质的溶解。) |
| 溶解性有机碳 | dissolved organic carbon The fraction of total organic carbon (all carbon atoms covalently bonded in organic molecules) in water that passes through a 0.45 micron pore-diameter filter (水中全部有机碳(即所有碳原子以共价键联结成的有机分子)能通过0.45微米孔径滤纸所占的比例。) |
| 溶解氧 | dissolved oxygen The amount of oxygen dissolved in a stream, river or lake is an indication of the degree of health of the stream and its ability to support a balanced aquatic ecosystem. The oxygen comes from the atmosphere by solution and from photosynthesis of water plants. The maximum amount of oxygen that can be held in solution in a stream is termed the saturation concentration and, as it is a function of temperature, the greater the temperature, the less the saturation amount. The discharge of an organic waste to a stream imposes an oxygen demand on the stream. If there is an excessive amount of organic matter, the oxidation of waste by microorganisms will consume oxygen more rapidly than it can be replenished. When this happens, the dissolved oxygen is depleted and results in the death of the higher forms of life (溶解在溪流、河水或湖泊中的氧气浓度，可作为河川的健康程度和维持水生态系平衡能力的指标。水中溶氧来自于大气的溶解和水生植物的光合作用。河川水体所能维持的最大氧气浓度﹐称之为饱和溶氧量﹐其值与温度有关；温度愈高，水中饱和溶氧量愈低。 当有机废弃物排入河川，会导致河川的需氧量增加；而过量的有机物进入水体时，微生物氧化这些有机物所消耗的氧量远快于氧气补充入水的速率，一旦氧气被消耗殆尽，会导致较高等生物的死亡。) |
