| 中文摘要: |
| 针对轻工业技术科学领域数十年一直沿用的“液固比(或液料比 )”这一约定俗成的名称,提出了“相除关系之商不能都称作比率”的观点。分析所谓“液 固比”的错误所在,并认为量纲不为一的量必须标明单位。例析了比率相关量如质量比与质 量分数、摩尔比与摩尔分数、体积比与体积分数的区别。建议轻工业酿造酒行业将传统的“ 酒度”改称为标准化的“酒精体积分数”。 |
| 英文摘要: |
| The conventional term “liquid/solid ratio” or “liquid/material ratio” has been using in the area of light industry for many years. The author presents a point of view that it cannot be named as “ratio” for all the quotients by dividing two numbers. The author also analyzes the mistakes of the so called “liquid/solid ratio” and holds that the units must be marked for those quantities if their dimension is not 1. Examples are given to differentiate quantity ratio and mass fraction, mol ratio and mol fraction, cubage ratio and cubage fraction. The author suggests to change the conventional term “wine degree” into standardized “alcohol cubage fraction” in the brewage industry. Keywords\ ratio; dimension; fraction Author’s address\Editorial Department of Journal of Jiangnan University,214122,Wuxi,Jiangsu,China |
