【摘要】 <正> 动物尿能值是代谢试验必需的参数。尿能测定的准确性主要取决于所取干尿样的数量与燃烧时载体产热误差的大小。用冻干法冻干后则热、成本及设备要求高,用纤维吸附法易受载体产热误差的影响。我们过去是用定量滤纸作载体的滤纸吸附法,但效果仍不理想,每次燃烧时尿样热值与载体热值之更多还原

【Abstract】 The usual way of using filter paper as loader for urine was compared to polytyrene beaker and our handmade plastic tubes in energy determinations. The differences were insignificant. The standard errors of the means from the handmade tubes were less than those of the other two.更多还原
