Abstract
Urinary density can be determined by measuring the change in the natural frequency of a hollow oscillator when filled with liquids of different density. The method requires only 0.6 ml of sample, and the precision is plus or minus 2. 5 - 10-4 g/cm-3. For clinical use a determination rate of approximately 60 samples an hour with a precision of 1 - 10-3 g/cm-3 may be reached.
摘要
尿比重可通过测量空心振荡器在填充不同密度液体时固有频率的变化来确定。该方法仅需0.6毫升样品，精度为±2.5×10⁻⁴克/立方厘米。用于临床时，每小时大约可测定60个样品，精度可达1×10⁻³克/立方厘米。
