“maturation”的概念、定义、翻译、参考文献-科学参考

maturation

Chemical Engineering

An aging process used in the production of whisky following the process of distillation in which the distilled spirit is placed in wooden casks for long periods of time. There is a legal requirement to mature Scotch whisky for a minimum of three years and it is often much longer. During this time flavours from the casks that have been previously used in the wine, sherry, cognac, and port industries are imparted, and include lignin and vanillin from the wood. The aging process also imparts colour. Around 2 per cent is lost each year through evaporation known as the angel’s share.

Biology

1. The process of becoming fully developed, especially the final phase in the development of germ cells, which renders the egg or sperm capable of fertilization.
2. Changes in the neuromuscular system as an animal develops that improve coordination regardless of experience.

Geology and Earth Sciences

The evolution of hydrocarbons through the increasing pressure and temperature associated with burial. In the immature stage the product is gas; as it matures the development of heavy oils is succeeded by medium, and finally light oils. If the temperature exceeds approximately 100 °C, however, dry gas is the sole product and the stage of incipient metamorphism is reached. See also natural gas; petroleum.
