“specific”的概念、定义、翻译、参考文献-科学参考

specific

Physics

1. Denoting that an extensive physical quantity (see extensive variable) so described is expressed per unit mass. For example, the specific latent heat of a body is its latent heat per unit mass. When the extensive physical quantity is denoted by a capital letter (e.g. L for latent heat), the specific quantity is denoted by the corresponding lower-case letter (e.g. l for specific latent heat).

2. In some older physical quantities the adjective ‘specific’ was added for other reasons (e.g. specific gravity, specific resistance). These names are now no longer used.

Chemical Engineering

Relating to a specified or particular thing, such as being a characteristic property especially in relation to the same property of a standard reference substance expressed per unit mass. For example, the latent specific heat of a substance is the latent heat per unit mass. The adjective is also used in relation to other terms, such as specific speed, in which the performance of a centrifugal pump is compared to the performance of other pumps.
